Description

 Composition containing perfume oil and perfume capsules

The present invention relates to a composition in the form of a suspension comprising at least one free perfume oil, at least one encapsulated perfume oil and at least one specific stabilizer. Further, the present invention is directed to a process for making such a composition and to the use of the stabilizers described herein for stabilizing a composition containing both perfume oil and perfume capsules. Furthermore, the present invention also relates to an agent, such as cosmetic products, detergents or cleaners, containing at least one composition as described herein.

The commonly used detergents and cleaners as well as cosmetics are usually perfumed. In addition to the actual perfuming by the free fragrances, for example in the form of perfume oils, increasingly encapsulated perfumes are used. Consumers demand both sufficient self-scenting of the product and coverage of "bad" secondary odors, as well as long-lasting and fresh perfumes, which can be achieved in an advantageous manner by the use of encapsulated fragrances.

In the production of corresponding products, the perfume oil is currently dosed directly into the corresponding product formulations or sprayed on pul verförmigen products also. The latter inevitably leads to undesirable losses. Before and during the dosing of encapsulated perfumes (capsule slurries), it is necessary to thoroughly homogenize them to ensure a homogeneous and qualitatively appropriate dosage. This process step is not particularly economical due to the high expenditure of time. In addition, two metering operations with two separate metering units are required for the metering of the perfume oil and the encapsulated perfuming. Again, the economic aspect is not optimal due to the longer production times and investments in metering units. In addition, very small amounts (<0.05%) of encapsulated perfumes can currently only be dosed with a high error.

The object of the present invention was therefore to provide a stable combination of perfume oils and encapsulated perfumes (capsule slurries) in order to realize a simple and efficient dosing of the described components.

It has now been found that this object is achieved by the addition of at least one stabilizer selected from the group of the alk (en) ylsulfosuccinamates according to formula I, where R = Cs-ds-alkyl, C8-Ci8 alkenyl and M ⁺ = Na ⁺ , K ⁺ , NhV, to a mixture containing both perfume oil and perfume capsules, can be dissolved.

In a first aspect, the present invention is therefore directed to a composition, characterized in that the composition comprises at least one free perfume oil, at least one encapsulated perfume oil and at least one stabilizer selected from the group according to formula I. The composition is in the form of a stable suspension of the perfume capsules in the liquid components of the composition.

In a further aspect, the present invention is directed to a process for preparing a composition as herein described, characterized in that the at least one perfume oil, the at least one encapsulated perfume oil and the at least one stabilizer are mixed together.

In a further aspect, the present invention is directed to the use of at least one stabilizer selected from the group of the alk (en) ylsulfosuccinamates according to the present invention for stabilizing a composition comprising at least one free perfume oil and at least one encapsulated perfume oil.

In yet another aspect, the present invention is directed to a cosmetic product, a laundry or cleaning composition comprising at least one composition 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. Any feature of one aspect of the invention may be employed in any other aspect of the invention. Further, it is to be understood that the examples contained herein are intended to describe and illustrate the invention, but not to limit it, and in particular that the invention is not limited to these examples.

All percentages are, unless otherwise stated,% by weight, in each case based on the total weight of the corresponding composition. Numeric ranges given in the format "from x to y" include the values mentioned If numeric ranges are specified in this format, it goes without saying that all ranges resulting from the combination of the various endpoints are also captured.

"At least one" as used herein refers to 1 or more, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9 or more.

"Approximately" as used herein in numerical terms means the corresponding value ± 10%, preferably ± 5%, more preferably ± 3%, most preferably ± 1%.

A first object of the present invention is a composition which is preferably in the form of a suspension. The suspension comprises at least one free perfume oil, at least one encapsulated perfume oil and at least one stabilizer according to the present invention.

In the context of the present invention, the term "perfume oil" refers to individual fragrance or fragrance compounds or mixtures of several such compounds, and thus includes, for example, ester, ether, aldehyde, ketone, alcohol, and hydrocarbon synthetic products, as well as natural fragrance mixtures, such as those vegetable sources are accessible.

In the context of the present invention, the term "free perfume oil" refers to a perfume oil which is present as such in a suspension as described herein, i.e. the individual components of the perfume oil are, in particular, unencapsulated.

A fragrance is an odor-causing chemical substance. In order to stimulate the sense of smell, the chemical substance should be at least partially redistributable in the air, i. the perfume should be at e.g. 25 ° C at least to a small extent volatile. If the fragrance is very volatile, the odor intensity sounds quickly again. At a lower volatility the odor impression is more sustainable, i. he does not disappear so fast. In one embodiment, therefore, the perfume has a melting point in the range of -100 ° C to 100 ° C, preferably from -80 ° C to 80 ° C, more preferably from -20 ° C to 50 ° C, especially of 30 ° C to 20 ° C. In a further embodiment, the perfume has a boiling point ranging from 25 ° C to 400 ° C, preferably from 50 ° C to 380 ° C, more preferably from 75 ° C to 350 ° C, especially from 100 ° C to 330 ° C is located.

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

The smell of a fragrance is perceived by most people as pleasant and often corresponds to the smell of, for example, flowers, fruits, spices, bark, resin, leaves, grasses, mosses and roots. Thus, fragrances can also be used to superimpose unpleasant odors or even to provide a non-smelling substance with a desired odor.

In various embodiments, the composition described herein contains the at least one free perfume oil in an amount of 10 to 98 wt.%, Preferably 10 to 95 wt.%, More preferably 15 to 90 wt.%, Preferably 50 to 95 Wt .-%, based on the total weight of the composition.

Furthermore, the composition / suspension according to the present invention comprises at least one perfume oil which is in the form of an encapsulated perfume oil, i. in the form of perfume oil capsules, is present.

In the context of the present invention, the term "encapsulated perfume oil" means a perfume oil which is present inside a capsule, ie it is not a free perfume oil, wherein the at least one appropriately encapsulated perfume oil may be a perfume oil as defined above and may be one or more comprise several of the aforementioned fragrances.

A "capsule" in the context of the present invention is constructed in particular of a casing and a core, wherein at least one perfume oil, as defined above, is present in the core, and optionally further advantageous agents, for example textile care agents be liquid or viscous, ie for example also present as a melt or have a wax-like structure are possible both capsules in which the at least one perfume oil and, optionally, the / the other (s) benefit agent is substantially contained in pure substance, and capsules in which the core is formed by a carrier mixed or impregnated with the at least one perfume oil and, optionally, the further benefit agent (s) Preferably, the core of the capsules is at temperatures below 120 °, preferably below 80 ° C, especially below 40 ° C liquid, viscous or at least meltable.

Particularly preferred capsules in the context of the present invention are those which have a mean diameter d 50 of <250 μm, preferably 1 to 100 μm, preferably 5 to 80 μm, particularly preferably 10 to 50 μm and in particular 15 to 40 μm , The dso value indicates the diameter which results when 50% by weight of the capsules have a smaller diameter and 50% by weight of the capsules have a larger diameter than the dso value determined. It is further preferred that the dgo value of the particle size distribution of the microcapsules is <70 pm, preferably <60 pm, particularly preferably <50 m. The dgo value of the particle size distribution is the value at which 90% of all particles are smaller and 10% of the particles are larger than this value.

The determination of the diameter of the capsules or the particle size of the microcapsules can be carried out by conventional methods. It can be determined, for example, by means of dynamic light scattering, which is usually carried out on dilute suspensions, e.g. 0.01 to 1 wt .-% capsules, can be performed. It can also be done by evaluating light microscopic or electron micrographs of capsules.

As materials for the capsule wall are usually high molecular weight compounds, in particular polymers, in question, such. Proteins (e.g., gelatin, albumin, casein, and others), cellulose derivatives (e.g., methylcellulose, ethylcellulose, cellulose acetate, cellulose nitrate, carboxymethylcellulose, and others), and especially synthetic polymers (e.g., polyamides, polyethylglycols, polyurethanes, epoxies, and others). For example, melamine-urea-formaldehyde resins or melamine-formaldehyde resins or urea-formaldehyde resins may preferably be used as capsule wall materials.

The capsules can release the encapsulated fragrances via various mechanisms. They are e.g. Capsules can be used, which have a mechanically stable capsule shell, but then due to one or more environmental factors, such as change in temperature or ionic strength or the pH of the surrounding medium, for the contained funds is permeable. Also possible are stable capsule wall materials through which the at least one perfume oil as well as the one or more further advantageous agents can diffuse through over time. The capsules may release the at least one perfume oil and the further advantage (s) preferably when the pH or ionic strength of the environment changes, as the temperature changes, upon exposure to light, through diffusion and / or under mechanical stress.

In a preferred embodiment of the present invention, the capsules are fragile, that is, they can contain entrapped agent due to mechanical stress such as friction, pressure or shearing stress breaking the shell of the capsules. In another preferred embodiment, the capsule is thermally labile, that is, entrapped materials may be released when the capsules are at a temperature of at least 70 ° C, preferably at least 60 ° C, more preferably at least 50 ° C, and most preferably at least 40 ° C is exposed.

In a further preferred embodiment, the capsule for the entrapped agent (at least one perfume oil and optionally one or more other benefit agents) may become permeable after exposure to radiation of a certain wavelength, preferably by the action of sunlight.

It is also possible that the capsules are fragile and at the same time thermally labile and / or unstable to radiation of a specific wavelength.

The capsules which can be used according to the invention may be water-soluble and / or water-insoluble capsules, but are preferably water-insoluble capsules. The water insolubility of the capsules has the advantage that these wash, unification or other treatment applications can survive and so are capable of the at least one perfume oil and other Vorteilsitte! only after the aqueous washing, cleaning or treatment process, such as when drying by mere increase in temperature or by sunlight or in particular friction of the surface.

Particularly preferred are water-insoluble capsules which are broken up by friction, wherein the wall material preferably melamine-formaldehyde resins, polyurethanes, polyolefins, polyamides, polyureas, polyesters, polysaccharides, epoxy resins, silicone resins and / or Pdykondensationsprodukte Carbonyi compounds and NH-containing compounds ,

The term "drippable" or "breakable by friction" capsules, means in particular those capsules, which, if they adhere to a surface treated therewith (eg textile surface) can be opened or broken by mechanical rubbing or by pressure, so that a Content release only results as a result of mechanical action, for example when one dries hands with a towel on which such capsules are deposited. Preferably usable, reusable capsules have average diameter dso in the range of 1 to 100 μιτι, preferably between 5 and 95 μιη, in particular between 10 and 90 μιτι, eg between 10 and 80 μιτι, for example between 15 and 40 μιτι. The shell of the capsules enclosing the core or (filled) cavity preferably has an average thickness in the range between approximately 0.01 and 50 μm, preferably between approximately 0.1 μm and approximately 30 μm. in particular between about 0.5 pm and about 8 pm or about 5 pm. Capsules are particularly easy to squeeze if they are within the ranges given above regarding the average diameter and the average thickness.

Microcapsules with capsule walls of melamine-formaldehyde resins are particularly advantageous because of their excellent impermeability and mechanical stability.

Methods for microcapsulation are known and described, for example, in US 20030004226 A1 (BASF), to which reference is hereby made.

Usually, during production, the core material, i. the at least one perfume oil, and optionally further benefit agents, in an aqueous solution of a protective colloid, which preferably has an acidic pH, emulsified into fine droplets. To the resulting emulsion is then added while mixing e.g. the aqueous solution of a melamine-formaldehyde precondensate or melamine and formaldehyde added individually for in-situ polymerization. This forms microcapsules. Upon completion of the addition, the condensation is completed. The capsules can be preformed, which is preferred, but also preformed, and then preferably by increasing the temperature (for example, temperature of at least about 40 ° C, preferably about 75 to 95 ° C) cure the capsule wall.

According to a preferred embodiment of the invention, the capsule dispersion according to the invention comprises water-insoluble microcapsules, preferably core-shell microcapsules, wherein the capsule walls in particular comprise melamine-formaldehyde resins. These microcapsules may contain, in addition to the at least one perfume oil, other liquids, but also readily solids, e.g. in the form of dispersions, for example, very fine hydrophobic silica dispersed in the at least one perfume oil.

In various embodiments of the invention, the capsules may comprise, in addition to the at least one perfume oil, at least one benefit agent, such as in particular skin care agents, fabric care agents and / or odor neutralizers. Under the term Advantage Center! in particular

According to the present invention, the at least one encapsulated perfume oil is usually in the form of a (capsule) slurry, i. a slurry of the capsules in a liquid medium.

The term "slurry" in the context of the present invention refers to a, typically aqueous, slurry of the perfume capsules as defined above The liquid medium is preferably predominantly, ie more than 50% by weight, but may or may not be water completely, ie 100% water. The slurry is preferably pourable, ie it can be poured out of a vessel by tilting the vessel. A castable slurry is understood as meaning, in particular, a capsule / liquid mixture which, in particular at the processing temperature, preferably at not more than 40 ° C., in particular at not more than 20 ° C., has a viscosity of less than 10-10 ⁴ mPas (Brookfield otation viscometer, spindle 2, 20 U / min.).

The slurry may contain other auxiliaries, for example those which ensure a certain durability or stability. Frequently used adjuvants include, for example, surfactants, especially anionic and / or nonionic surfactants. Corresponding capsule slurries are commercially available and known to those skilled in the art.

In various embodiments, the capsules described above in an amount of 1 to 50 wt .-%, preferably 20 to 48 wt .-%, in particular 35 to 45 wt .-% in the slurry.

In various embodiments, the composition according to the invention is characterized in that the at least one encapsulated perfume oil in the form of a capsule slurries in an amount of 2 to 90 wt .-%, preferably from 2 to 89 wt .-%, preferably from 2 to 85 wt. %, more preferably from 3 to 70 wt .-%, more preferably 4 to 50 wt .-% based on the total weight of the composition in this is contained. Accordingly, in consideration of the fact that the slurry preferably contains the capsules only in an amount of from 1 to 50, in particular from 20 to 48,% by weight, the proportion of capsules in various embodiments is from 0.02 to 45, preferably from 0.4 to 43.2, more preferably 0.6 to 33.6 wt .-% based on the total weight of the composition.

In various embodiments, the weight ratio of the at least one free perfume oil to the capsule slurry as described above is from 10:90 to 98: 2, preferably from 50:50 to 95: 5.

The perfume oil capsule suspension according to the present invention further comprises at least one stabilizer selected from the group consisting of alk (en) sulfosuccinamates according to the present invention.

The stabilizer serves to stably disperse the capsules in the composition.

In various embodiments, the at least one stabilizer is contained in an amount of from 0.05 to 10% by weight, preferably in an amount of from 0.5 to 5% by weight, based on the total weight in the composition. As already mentioned above, the composition according to the invention is preferably in the form of a suspension of the capsules in a continuous, liquid phase. The suspension is preferably stable, ie it comes even after prolonged storage periods of for example several days to weeks at usual temperatures in the range up to 40 ° C, for example 4 weeks at a temperature between> 0 and 40 ° C, not to agglomeration, sedimentation and / or floating the capsules or other phase separation. In various embodiments, the composition contains water, which is introduced, for example, via the capsule slurry. The water content may be, in various embodiments, from about 5 to 50 wt%, preferably 5 to 40 wt%, more preferably 5 to 20 wt%, even more preferably 5 to 10 wt%. In such embodiments, water may form the continuous phase in which the capsules and optionally also the perfume oil are (stably) dispersed, ie the suspension is an aqueous suspension. It should be noted here that even in embodiments in which the water phase does not constitute the main portion of the liquid phase, for example, the perfume oil may be contained in a relatively larger amount, the water phase may form the continuous phase in which the other phase suspends or emulsifies are.

In various embodiments, the composition as described above is further characterized by having a viscosity of from 50 to 5000 mPas, preferably from 100 to 3000 mPas (Brookfield rotational viscometer, spindle 2, 20 rpm).

In addition, the composition / suspension may additionally contain further ingredients which are typically contained in detergents or cleansing products or cosmetic products. For example, in one embodiment, the perfume oil capsule suspension contains, in addition to the at least one free perfume oil, at least one encapsulated perfume oil in the form of a capsule slurries and the at least one stabilizer as described herein, one or more dyes (e ). The dyes may be present in an amount of 0.01-5 wt .-% in the composition.

The present invention further provides a process for preparing a composition, ie a perfume oil capsule suspension as described above, characterized in that the at least one perfume oil containing at least one encapsulated perfume oil in the form of a capsule slurries and the at least one Stabilizer are mixed together. Suitable methods of mixing the foregoing components are known in the art and may include, for example, mixing in a homogenizer. In the event that one or more of the aforementioned components are not liquid at room temperature, the respective components may be heated prior to mixing with the other components, for example at temperatures between 20 ° C to 100 ° C, preferably between 25 ° C and 60 ° C so as to facilitate mixing with the remaining components.
