EP3476927B1 - Solid composition containing perfume - Google Patents

Description

The present invention relates to fusible bodies according to claim 1.

The invention also relates to a method for producing the solid composition according to claim 8 and a washing or cleaning agent containing the solid composition according to claim 10. The present invention also relates to the use of such a solid composition as a textile care agent for scenting of textile fabrics according to claim 9.

When using detergents and cleaning agents, the consumer not only pursues the goal of washing, cleaning or caring for the objects to be treated, but he also wishes that the treated objects, such as textiles, after the treatment, for example after the laundry, smell pleasant. For this reason in particular, most commercially available detergents and cleaning agents contain fragrances.

Fragrances in the form of fragrance particles are often used either as an integral part of a washing or cleaning agent, or else are metered into the washing drum in a separate form directly at the start of a wash cycle. In this way, the consumer can control the scent of the laundry to be washed through individual dosing.

The main component of such fragrance pastilles known in the prior art is typically a water-soluble or at least water-dispersible carrier polymer, such as polyethylene glycol (PEG), which serves as a vehicle for the integrated fragrances and which more or less completely dissolves in the washing liquor during the waxing process dissolves in order to release the fragrances contained and any other components in the wash liquor. For the production of the known scent pastilles, a melt is produced from the carrier polymer, which contains the other ingredients or these are then added, and the melt obtained is then fed to a shaping process during which it cools, solidifies and assumes the desired shape.

The known products have the disadvantage that the polymer materials used, in particular PEG, have delayed solubility, which can lead to residues on the laundry or in the washing machine, particularly with short wash cycles, low temperatures or other unfavorable conditions.

For example, a solid particulate detergent composition comprising sodium acetate trihydrate, a fragrance and a buffering system is disclosed in EP 1 054 946 A1 or U.S. 2004/033924 A1 or U.S. 2004/152616 A1 disclosed.

U.S. 2003/109396 A1 discloses detergents which reduce wrinkling with the aid of triglycerides.

However, it has now been found that an alternative composition, which shows a suitable processing range and at the same time has improved water solubility in the usual temperature ranges in which work is carried out, can be provided by using a water-containing salt ( hydrate) is used, the water vapor partial pressure of which at a certain temperature in the range from 30 to 100°C corresponds to the H ₂ O partial pressure of the saturated solution of this salt at the same temperature, so that the salt dissolves in its own crystal water at this temperature, a process which can be described phenomenologically as melting, but which is thermodynamically a solution process. The use of sodium acetate trihydrate is particularly advantageous.

However, sodium acetate and its hydrate has the disadvantage that although it is odorless as such, it produces an essign note when it comes into contact with acid, even weak acid, since the action of the acid drives acetic acid out of the acetate. It has been shown that the pH value of human skin of approx. 5.5 is already sufficient to leave a vinegar smell on the skin when it comes into contact with the sodium acetate-based lozenges, which the consumer can find unpleasant.

A solution to this problem would be to add alkali, such as caustic soda. Here, however, the problem arises that many fragrances can be damaged by excessive alkalinity, which can lead to odor off-notes.

The object of the present invention was therefore to find a system which, on the one hand, is capable of buffering the protective acid mantle of the human skin, but, on the other hand, does not damage the fragrances. This object was achieved according to the invention in that the sodium acetate-based composition additionally contains a buffer system which can buffer the effects of acids.

In yet another aspect, the present invention is directed to the use of the melt bodies, as described herein, as textile care agents, preferably scenting agents, for scenting textile fabrics.

In another aspect, the present invention further relates to a detergent or cleaning agent, comprising a melt body as described herein.

These and other aspects, features and advantages of the invention will become apparent to those skilled in the art from a study of the following detailed description and claims. Each feature from one aspect of the invention can be used in any other aspect of the invention. In particular, it is intended that all preferred embodiments described herein can be transferred to or combined with all aspects of the invention. This applies in particular to the first to eighth aspects of the invention as described above. Furthermore, it should be understood that the examples contained herein are intended to describe and illustrate the invention, but not to limit it, and in particular the invention is not limited to these examples.

All percentages are % by weight unless otherwise stated. Numerical ranges given in the format "from x to y" include the stated values. Where multiple preferred numeric ranges are given in this format, it is understood that any ranges resulting from the combination of the different endpoints are also included.

"At least one" as used herein refers to 1 or more, for example 1, 2, 3, 4, 5, 6, 7, 8, 9 or more. In particular, this information relates to the nature of the agent/compound and not to the absolute number of molecules. "At least one fragrance, therefore means that at least one type of fragrance is detected, but 2 or more different types of fragrance can also be included.

"About" or "about" as used herein in connection with a numerical value means the numerical value ±10%, preferably ±5%. A temperature of about 50°C thus means 45-55°C, preferably 47.5-52.5°C.

"Water-soluble" as used herein means a solubility in water at 20°C of at least 1 g/L, preferably at least 10 g/L, more preferably at least 50 g/L.

The solid, particulate composition as described herein is prepared from a solution of the carrier material in the water/crystal water contained in the composition, the term "melt" also being used here for such a solution, in contrast to the established usage, to describe the state in which the carrier material dissolves in its own water of crystallization due to the elimination of water and thus forms a liquid. The term "melt", as used herein, thus designates the liquid state of the composition, which occurs when the temperature is exceeded at which the carrier material splits off water of crystallization and then dissolves in the water contained in the composition. The corresponding dispersion, which contains the (solid) substances described herein dispersed in the melt of the carrier material, is therefore also a subject of the invention. So when reference is made below to the solid, particulate composition, the corresponding melt/melt dispersion from which it can be obtained is always included. Since these do not differ in composition, with the exception of the physical state, the terms are used synonymously here.

The term "fused body" is used herein to describe the solid particles obtainable from a liquid composition upon cooling by solidification/transformation.

The main component of the melted bodies as described herein is at least one water-soluble carrier material. The carrier material is characterized in that it is a water-containing salt whose water vapor partial pressure at a temperature in the range from 30 to 100° C. corresponds to the H ₂ O partial pressure of the saturated solution of this salt at the same temperature. This means that the corresponding water-containing salt, also referred to herein as "hydrate", changes when this temperature is reached or exceeded dissolves in its own water of crystallization and thus changes from a solid to a liquid state of aggregation. The carrier materials according to the invention preferably show this behavior at a temperature in the range from 40 to 90.degree. C., particularly preferably between 50 and 85.degree. C., even more preferably between 55 and 80.degree.

According to the invention, the carrier material is sodium acetate trihydrate (Na(CH ₃ COO).3H ₂ O).

According to the invention, the hydrate is sodium acetate trihydrate (Na(CH ₃ COO).3H ₂ O), since it dissolves in its own crystal water in the particularly preferred temperature range of 55 to 80° C., specifically at about 58° C. The sodium acetate trihydrate can be used directly as such, but alternatively the use of anhydrous sodium acetate in combination with free water is also possible, the trihydrate then being formed in situ. In such embodiments, the water is used in less than or more than the stoichiometric amount based on the amount necessary to convert all of the sodium acetate to sodium acetate trihydrate, preferably in an amount of at least 60% by weight, preferably at least 70% by weight %, more preferably at least 80%, most preferably 90%, 100% or more by weight of the amount theoretically required to convert all the sodium acetate to sodium acetate trihydrate (Na(CH ₃ COO) · 3H ₂ O). The more than stoichiometric use of water is particularly preferred. Based on the compositions according to the invention, this means that if (anhydrous) sodium acetate is used alone or in combination with a hydrate thereof, preferably the trihydrate, water is also used, the amount of water being at least the amount that would be stoichiometrically necessary. to ensure that at least 60% by weight of the total amount of sodium acetate and its hydrates, preferably at least 70% by weight, more preferably at least 80% by weight, even more preferably at least 90% by weight, most preferably at least 100% by weight, is in the form of sodium acetate trihydrate. As already described above, it is particularly preferred that the amount of water exceeds the amount that would theoretically be necessary to convert all of the sodium acetate into the corresponding trihydrate. This means, for example, that a composition containing 50% by weight anhydrous sodium acetate and no hydrate thereof contains at least 19.8% by weight water (60% of the 33% by weight that would theoretically be necessary to contain all the sodium acetate into the trihydrate).

All of the embodiments described below can be explicitly combined with both of the aforementioned alternatives.

In various embodiments, the carrier material is used in an amount such that the resulting melted body, i.e. the scented pastille, is from 30 to 95% by weight, preferably from 40 to 90% by weight, for example 45 to 90% by weight, based on the total weight of the melted body containing the carrier material.

Another component of the melted body as described herein is at least one fragrance. A fragrance is a chemical that stimulates the sense of smell

Substance. In order to be able to stimulate the sense of smell, the chemical substance should be at least partially airborne, i.e. the fragrance should be at least slightly volatile at 25°C. If the fragrance is now very volatile, the odor intensity then quickly fades away. With a lower volatility, however, the odor impression is more lasting, i.e. it does not disappear as quickly. In one embodiment, the fragrance therefore has a melting point in the range from -100°C to 100°C, preferably from -80°C to 80°C, more preferably from -20°C to 50°C, in particular from - 30°C to 20°C. In a further embodiment, the fragrance has a boiling point which is in the range from 25° C. to 400° C., preferably from 50° C. to 380° C., more preferably from 75° C. to 350° C., in particular from 100° C. to 330°C.

Overall, a chemical substance should not exceed a specific molecular mass in order to function as a fragrance, since the required volatility can no longer be guaranteed if the molecular mass is too high. In one embodiment, the fragrance has a molecular mass of 40 to 700 g/mol, more preferably 60 to 400 g/mol.

The smell of a fragrance is perceived as pleasant by most people and often corresponds to the smell of, for example, blossoms, fruits, spices, bark, resin, leaves, grass, moss and roots. Fragrances can also be used to mask unpleasant odors or to provide a non-smelling substance with a desired smell.

The silicas used are preferably highly disperse silicas, for example those with BET surface areas of more than 50 m ² /g, preferably more than 100 m ² /g, more preferably 150 to 250 m ² /g, in particular 175 to 225 m ² /g .

Suitable silicas are commercially available from Evonik under the trade names ^Aerosil® and ^Sipernat® . ^Aerosil® 200 is particularly preferred.

In various embodiments, the composition can additionally or alternatively contain other (at 20° C. and 1 bar) solid or liquid ingredients that can be used to set desired properties of the composition. Such properties can also be the viscosity or the rheological properties of the melt. Such substances are, for example, organic rheology modifiers, preferably cellulose, in particular microfibrillated cellulose (MFC, nanocellulose). MFCs are particularly suitable as cellulose, such as those found, for example, as Exilva (Borregaard) or Avicel ^® (FMC) are commercially available. In addition or as an alternative to the aforementioned substances, further solids or fillers that differ from the aforementioned can be contained.

Microfibrillated cellulose (MFC) is preferably used in amounts of up to 5% by weight, more preferably 0.1 to 3% by weight, more preferably 0.3 to 2% by weight, based in each case on the total weight of the composition, deployed.

Also suitable as ingredients are emulsifying substances such as fatty alcohols, such as stearyl alcohol, fatty alcohol alkoxylates, such as fatty alcohol ethoxylates used as nonionic surfactants, fatty alcohol and fatty alcohol ether sulfates and alkylbenzenesulfonates, especially those that are also used as anionic surfactants. Suitable fatty alcohol ethoxylates are in particular the C10-22 fatty alcohol ethoxylates with up to 50 EO, very particularly preferably the C12-18 alkyl ethers with 5-8, preferably 7EO, or the C16-18 alkyl ethers with up to 30 EO. Suitable fatty alcohol ether sulfates are the sulfates of the aforementioned fatty alcohol ethers, suitable fatty alcohol sulfates in particular the C10-18 fatty alcohol sulfates, especially the C12-16 fatty alcohol sulfates. The linear C10-13 alkylbenzene sulfonates are particularly suitable as alkyl benzene sulfonates. In summary, emulsifiers from the group consisting of fatty alcohols, fatty alcohol alkoxylates, fatty amide ethoxylates, fatty alcohol sulfates, fatty alcohol ether sulfates, alkyl benzene sulfonates, allyl polyglycosides, fatty acid sorbitan esters, alkyl amine oxides, alkyl betaines or combinations thereof are preferred.

The composition may contain other solids or fillers (f) other than components (a) to (f). The proportion by weight of these solids or fillers in the total weight of the composition is, for example, up to 25% by weight, preferably up to 20% by weight, more preferably up to 18% by weight, in particular up to 15% by weight, based on the total weight of the Composition to be used.

The composition according to any one of the preceding claims, characterized in that components (c) (d), (e), (f) and (g) are present together in amounts of 0 to 25% by weight, preferably 1 to 20% by weight. -%, more preferably 2 to 18% by weight, in particular 3 to 15% by weight, based on the total weight of the composition, are present in the composition.

In order to improve the aesthetic appeal of the composition, it can be colored with suitable dyes. Preferred dyes, the selection of which presents no difficulty to the person skilled in the art, should have a high storage stability and be insensitive to the other ingredients of the detergent or cleaning agent and to light and not have any pronounced substantivity to textile fibers so as not to stain them. Such dyes are known in the prior art and are typically used in concentrations of 0.001 to 0.5% by weight, preferably 0.01 to 0.3% by weight.

As already described above, the composition may also contain free water. The term "free water" as used herein refers to water which is not bound as water of crystallization in any of the salts contained in the composition.

A composition as described herein can be used, for example, in the wash cycle of a laundry cleaning process and thus transport the perfume to the laundry right at the start of the washing process. Furthermore, the composition according to the invention is easier and easier to handle than liquid compositions, since no drops remain on the edge of the bottle, which lead to edges on the substrate or unsightly deposits in the area of the closure when the bottle is subsequently stored. The same applies in the event that some of the composition is accidentally spilled during dosing. The spilled amount can also be cleaned up more easily and cleanly. A method for treating textiles, in the course of which a composition according to the invention is metered into the wash liquor of a textile washing machine, is another subject of this application.

The composition can optionally contain other customary ingredients, for example those which improve the performance and/or aesthetic properties.

The composition according to the present invention is a solid, particulate composition. The individual particles of the composition are referred to as melted bodies, which are solid at room temperature and temperatures of up to 30.degree. C., preferably up to 40.degree.

In various embodiments of the invention, the melting bodies according to the invention are coated. Tablet coatings known from the pharmaceutical literature, for example, are suitable as coating agents. However, the lozenges can also be waxed, i.e. coated with a wax, or powdered with a powdery material, for example a release agent, to prevent caking (agglomeration). It is preferred that the coating does not consist of PEG or that it comprises a significant amount (>10% by weight, based on the coating).

3. (c) Zudosieren, vorzugsweise kontinuierliches Zudosieren, des mindestens einen Duftstoffs und optional eines Farbstoffs zu der Schmelze;
4. (d) Mischen der Schmelze und des mindestens einen Duftstoffs; und
5. (e) Abkühlen und optional Umformen der Mischung um parfümhaltige Schmelzkörper zu erhalten.

A method for producing such a melting body can include the following steps:

1. (a) Generating, preferably continuously generating and conveying, a melt comprising the at least one water-soluble carrier material and the buffer system
2. (b) optionally metering in other optional ingredients;
3. (c) Metering, preferably continuous metering, of the at least one fragrance and optionally a colorant to the melt;
4. (d) mixing the melt and the at least one fragrance; and
5. (e) Cooling and optional reshaping of the mixture in order to obtain melt bodies containing perfume.

The melted bodies produced in this way can have any desired shape. The shaping takes place in particular in step (d) of the method described. Preference is given to solid, particulate forms, such as, for example, essentially spherical, figured, scaly, cuboid, cylindrical, conical, spherical cap or lens-shaped, hemispherical, disk-shaped or needle-shaped particles. For example, the particles can have a gummy bear-like, figurative configuration. Due to their packaging properties and their performance profile, hemispherical particles are particularly preferred.

It is also preferred if the composition consists of at least 20% by weight, preferably at least 40% by weight, particularly preferably at least 60% by weight and particularly preferably at least 80% by weight, of particles which in each have a spatial extent of between 0.5 to 10 mm, in particular 0.8 to 7 mm and particularly preferably 1 to 3 mm, in any spatial direction. Corresponding particles are characterized by increased customer acceptance due to their aesthetics.

Finally, it has proven to be advantageous for the dosage and the fragrance effect if the composition contains at least 20% by weight, preferably at least 40% by weight, particularly preferably at least 60% by weight and particularly preferably at least 80% by weight. -% consists of particles which have a particle weight between 2 and 150 mg, preferably between 4 and 60 mg and in particular between 5 and 10 mg.

The particularly preferred melted bodies described above, in particular those with a particle weight of between 2 and 150 mg, a spatial extent of between 0.5 and 10 mm and a hemispherical three-dimensional shape, can be produced in an advantageous manner by means of pastillation.

Within the scope of such a preferred variant of the method, the melt of the water-soluble carrier material is pressed into a heated inner body and a drum-shaped outer tube with numerous bores, which rotates concentrically around the fixed inner body and thereby deposits product drops over the entire width of a circulating cooling belt, preferably a steel belt .

The viscosity (Texas Instruments AR-G2 rheometer; plate/plate, 4 cm diameter, 1100 μm gap; shear rate 10/1 sec) of the mixture when it emerges from the rotating, perforated external drum is preferably between 1000 and 10000 mPas.

The droplets of the mixture discharged from the droplet former are solidified on the steel belt to form solid melted bodies. The time between dropping the mixture onto the steel strip and complete solidification of the mixture is preferably between 5 and 10 minutes 60 seconds, particularly preferably between 10 and 50 seconds and in particular between 20 and 40 seconds.

The solidification of the mixture is preferably supported and accelerated by cooling. The droplets applied to the steel strip can be cooled directly or indirectly. Cooling by means of cold air, for example, can be used as direct cooling. However, indirect cooling of the droplets by cooling the underside of the steel strip with cold water is preferred.

A very particularly preferred variant of the method, in particular for the production of the melted bodies described in the formulas 1 to 100 with regard to their composition, comprises the steps:

1. (a) generating, preferably continuously generating and conveying, a melt comprising the at least one water-soluble carrier material sodium acetate trihydrate (Na(CH ₃ COO).3H ₂ O) and the buffer system;
2. (b) optionally metering in other optional ingredients;
3. (c) Metering, preferably continuous metering, of the at least one fragrance, the at least one buffer system and optionally a colorant to the melt;
4. (d) mixing the melt and the at least one fragrance;
5. (e) application of droplets of the resulting mixture onto a cooling belt by means of a droplet former with a rotating, perforated outer drum; and
6. (f) solidification of the droplets of the mixture on the steel strip to form solid hemispherical melted bodies.

In various embodiments, a melt is generated, the melting, in step (a) of the methods described herein by heating to a temperature which is not more than 20 ° C above the temperature of the carrier material at which the water vapor partial pressure of the hydrate dem H ₂ O partial pressure of the saturated solution of this salt corresponds. As already described above, the carrier material can already be used as a hydrate or the hydrate is obtained by combining the anhydrous salt and water in a sub-stoichiometric, stoichiometric or super-stoichiometric amount, preferably a stoichiometric or super-stoichiometric amount, based on the amount required to convert the entire salt into the desired hydrate generated in situ prior to step (a) or in step (a).

The melting can be carried out using all customary methods and devices known to those skilled in the art. The melt, which contains the at least one carrier material, is produced continuously, for example, by mixing the at least one carrier material, the bitter substance and any other optional components of the melt body, such as the pyrogenic silica, the cellulose, the fatty alcohols, fatty alcohol alkoxylates, fatty alcohol sulfates, fatty alcohol ether sulfates, Alkyl benzene sulfonates or a solid or filler alone or in combination are fed continuously to a corresponding device in which they are heated and the melt thus produced is conveyed, for example pumped. However, the melt can also be produced separately, for example in a batch process. The invention also includes embodiments in which the components of the melt are mixed with one another at any point in time before carrying out the method according to the invention and the mixture is stored in molten or cooled solid form until the method is carried out. The melt produced in this way can be used as a masterbatch, to which in the following step different fragrances and possibly other ingredients such as dyes are then added as required.

In a next step, the at least one fragrance is then metered continuously into the melt. For this purpose, the at least one fragrance is preferably used in liquid form, for example as a perfume oil, a solution in a suitable solvent or as a suspension of perfume capsules in a typically aqueous solvent. "Liquid" as used in this context means liquid under the conditions of use, preferably liquid at 20°C. In addition to the fragrance, a dye can also be dosed in this step. The dye can be indicative of the type of fragrance, for example, ie a special dye or mixture of dyes is used for a specific fragrance/fragrance mixture in order to make the lozenges obtained visually distinguishable directly.

During production, the flow can optionally be controlled by measuring the flow rate of the individual dosing streams, i.e. the melt, the fragrance stream and, if necessary, other ingredient streams. This can also be used, for example, to set the proportions of the individual components. The ingredients in addition to the carrier material and the fragrances can either be produced directly with the carrier material as a melt, metered into the melt together with the fragrances or separately. In the latter alternative, metering can take place before or after metering in the fragrances.

In some embodiments, the method according to the invention is characterized in that the at least one buffer system and optionally at least one further component of the melted body, such as the pyrogenic silica, the cellulose, the fatty alcohols, fatty alcohol alkoxylates, fatty alcohol sulfates, fatty alcohol ether sulfates, alkyl benzene sulfonates or a solid or filler alone or are metered in combinations to the melt produced and conveyed in step (a) and/or are already contained in the melt produced and conveyed in step (a).

The mixing of the combined metered streams can then take place directly after metering or downstream after metering of several or all of the ingredients using suitable mixers, such as customary static or dynamic mixing units.

After mixing, the melt, which contains the fragrance, the buffer system and optionally solids and possibly other ingredients as well as the carrier material, is cooled and optionally fed to the forming process, where the melt solidifies and acquires its final shape. Suitable methods for shaping are known to those skilled in the art. Common forms have already been described above.

The invention also relates to the melting bodies obtainable by means of the processes described herein and to their use as textile care agents, preferably scenting agents for scenting textile fabrics. The melted bodies can be a textile treatment agent, such as a fabric softener, or part of such an agent.

The invention also relates to a washing or cleaning agent comprising the melted bodies produced according to the invention.

By introducing the perfume-containing melting bodies produced according to the invention into a washing or cleaning agent, the consumer has a textile-care washing or cleaning agent ("2-in-1" washing or cleaning agent) available and he does not need to dose two agents or a separate rinse cycle. Since the compositions produced according to the invention are perfumed, the washing or cleaning agent does not have to be perfumed as well. Not only does this result in lower costs, but it is also beneficial for consumers with sensitive skin and/or allergies.

The melt body compositions described here are particularly suitable for scenting textile fabrics and are brought into contact with the textile fabrics together with a conventional detergent or cleaning agent in the (main) wash cycle of a conventional washing and cleaning process.

If the hot-melt composition according to the invention is part of a detergent or cleaning agent, a solid detergent or cleaning agent can preferably be mixed with 1 to 20% by weight, in particular with 5 to 15% by weight, of the composition according to the invention.

The preferred embodiments described in connection with the methods according to the invention can also be applied to the melted bodies as such, the detergents and cleaning agents containing them and the uses described therein and vice versa.

The table below contains an example of a formulation according to the invention (all data in % by weight) Table 1: Compositions Sodium Acetate Trihydrate 84.70 Sodium Acetate (anhydrous) 56.0 Hydrophilic Fumed Silica (Aerosil 200) 1.50 C16/18 fatty alcohol 30 EO 0.80 Microfibrillated cellulose (2% in water) 29.2 Perfume 4.5 0.9 Perfume capsule slurry (50%) 5.5 5.8 Buffer system, preferably TRIS 0-5 (variable) 0-5 (variable) dye 0.1% water to 100 to 100

For the preparation, the sodium acetate trihydrate was heated to a temperature of 70° C. and largely dissolved in the water of crystallization which had been split off, with stirring. The other components were then incorporated. When using anhydrous acetate, the solution was prepared by stirring it with the water of the formulation and the microfibrillar cellulose containing 98% water at 70°C. Pastilles were produced by dropping the liquid mixture (“melt”) onto a cooling plate maintained at room temperature (23° C.).

The inventive fragrance pastilles produced in this way were then tested for their buffering capacity by dissolving 1 g of the pastilles in 50 mL deionized water in a 400 mL beaker while stirring with a magnetic stirrer at 300 rpm and 20° C. and then adding HCl (aq) were titrated until a pH of 6.75 was reached. The buffer capacities obtained are given in Table 2. Table 2: Buffer capacities mg (HCl) 1g pastilles 1.77 +1% TRIS 4.55 +2% TRIS 6.72 +5% TRIS 16.1 + ₁ % _Na2CO3 5.75 + ₅ % _Na2CO3 21.79
