Description

Description

Title of the invention: Dry shampoo without propellant The present invention relates to a dry shampoo without propellant. Furthermore, the present invention relates to a powder sprayer comprising the dry shampoo without propellant. Furthermore, the present invention relates to a process for treating keratin fibers and using the dry shampoo without propellant for hair care, for hair washing, in a hair coloring process and / or for setting temporary hair form.

Daily body care generally involves cleaning the hair with commercially available shampoos. Hair and scalp should be rid of skin fats formed in the sebaceous glands, which are secreted by the sebaceous glands under the name of sebum. In addition, the hair and scalp should be rid, when cleaning the hair, of inorganic salts, amino acids, urea and lactic acid, secreted by the sweat glands with water, as well only flaking skin particles, environmental soiling, odors and possibly residues of cosmetic treatments for the hair. Regular shampoos contain surfactants and other ingredients for this purpose.

It is known that the hair is moistened or wet with water during the usual washing of the hair, that the shampoo is massaged on the hair and then that the shampoo is rinsed with water. However, one may not wish to have to soak the hair in order to clean it, since the hairstyle, such as a notched ripple must not be undone. In addition, washing your hair with a regular shampoo may not be practical or may not be possible while traveling. Despite everything, it is necessary to clean your hair so that it does not have a shiny and dirty appearance.

Dry shampoos offer an alternative to washing compared to traditional shampoos. The objective of an application with dry shampoos is to remove dirt from the hair without destroying the hairstyle by washing with water. However, dry shampoos are not shampoos in the traditional sense of the term, because they do not contain any ingredient characteristic of shampoos. Their effect is based on the adsorption capacity and possibly an abrasive effect of the pulverulent particles, which applied to dry hair, are distributed as finely as possible on the hair, possibly massaging with a towel and are generally carefully removed by brushing after absorption of sebum and impurities.

Hair treatment with dry shampoos without surfactants, but containing solvents and propellants, which are sprayed by means of an aerosol device on the hair, is known. The starch particles contained in the dry shampoo absorb, after evaporation of the solvent, the sebum and the impurities and are removed by brushing after a certain time of action.

The drawback of these known dry shampoos lies on the one hand in the use of propellants. For reasons of environmental protection, it is advisable to avoid propellants. In addition, carrying aerosol cans containing propellants while traveling is impractical or should be avoided for safety reasons. Providing a dry shampoo without a propellant requires a dry shampoo composition which can be easily removed from a container. Said powder composition must be produced in such a way that it can be extracted from a container, for example by a pumping operation, in which the extraction must not be disturbed by the aggregation of the powder composition in the pump channel then blocked. Those skilled in the art will readily understand that extracting a powder composition from a container is technically more difficult to resolve than that of a solution or a paste. For the technically advantageous extraction of powder compositions, but also for the technically advantageous extraction of suspensions with a high content of solid particles, the nature of the powder or solid composition itself plays an important role.

In addition, dry shampoos have in principle a cleaning effect and a performance lower than that of conventional shampoos, so that it is necessary to provide improved dry shampoos. An improvement of these shampoos aims, on the one hand, to improve their cleaning effect, and on the other hand, to allow better shaping of the hair.

The problem underlying the invention is to overcome the aforementioned drawbacks of the prior art, in particular to provide an improved dry shampoo and environmentally friendly, which offers the user greater comfort. use.

The problem underlying the invention is resolved by the subject of claim 1. A first subject of the invention is therefore a dry shampoo without propellant comprising at least one homoglycan product and at least one hydrophobically modified silicic acid.

In the context of the present invention, the term “dry shampoo” means an appropriate composition intended for cleaning the hair, the dry shampoo becoming a dry shampoo due to the hair washing process, namely that it does not There is no need to dampen or wet the hair with water in the hair washing process, as is the case with a traditional shampoo.

The composition comprising at least one homoglycan product and at least one hydrophobically modified silicic acid is a dry shampoo which can be massaged into the hair without first wetting the hair. The dry shampoo can be brushed, without this operation being compulsory, to give hair that is cleaned or at least partially cleaned. It is even particularly preferred that the dry shampoo is not brushed and thus contributes to (temporary) shaping of the hair. In addition, the dry shampoo without propellant is characterized in that there is no addition of significant amounts of isolated surfactants, which are not adsorbed by particles.

In addition, only the compositions without propellant are in accordance with the invention, that is to say the compositions containing no expansive substance for extracting the compositions from a container.

A homoglycan product is a substance which is a homoglycan or contains a homoglycan, a homoglycan being a polysaccharide composed of similar monosaccharides. Homoglycans include, for example, cellulose or starch. In dry shampoo without propellant, the homoglycan product is used to absorb contaminants, odors, amino acids, lactic acid, etc., as well as to adsorb sebum and flaking skin particles. The advantage of using homoglycans is the availability from their natural sources, that is to say that they are renewable raw materials.

The dry shampoo without propellant also contains hydrophobically modified silicic acid. In the context of the present invention, the expression hydrophobically modified silicic acid is understood to mean any amorphous or partially amorphous silicon dioxide having on its surface silanol groups which react partially or entirely by chemical reaction, so that the surface is at least partially provided of an organic radical after the reaction. Hydrophobically modified silicic acids are used in many technical fields and are described in a variety of ways in the state of the art.

Hydrophobically modified silicic acid fulfills several functions in dry shampoo without propellant. On the one hand, it acts as an abrasive substance, that is to say, used to remove sebum, dirt particles and flaking skin particles. In addition, hydrophobically modified silicic acid contributes to the styling properties of dry shampoo. In particular, hydrophobically modified silicic acids create very good volume and texture of the hair, as well as a certain capacity for remodeling.

In addition, the combination of a homoglycan product and a hydrophobically modified silicic acid guarantees the property that the dry shampoo in the form of composition without propellant can be extracted in a reliable and practical manner. in a distributor without having a tendency to aggregate. The powder composition according to the invention must be produced in such a way that it can be extracted from a container, for example by a pumping operation, in which the extraction must not be disturbed by the aggregation of the pulverulent particles. in the pump channel then blocked. Hydrophobically modified silicic acid prevents aggregation of solids in the composition and allows the dry shampoo without propellant to flow in such a way that it can be extracted from a pump dispenser without clogging certain parts of the pump dispenser .

In a preferred embodiment, the homoglycan product is an adsorption product of a starch and a surfactant. In the context of the present invention, the term “adsorption product” means any product in which a surfactant is adsorbed on the surface of the starch. Due to the alcoholic groups of starch, their surface tends to be polar, so that a suspension of starch with a dissolved surfactant gives an adsorption product in which the surfactant is physically adsorbed on the particles d starch and thus generates the adsorption product. By surface-active substance is meant, in the context of the present invention, any substance which, in principle, is capable of forming micelles in water or which, when dissolved in water, reduces surface tension with respect to pure water.

In a preferred embodiment, the starch used for the homoglycan product has an amylose content, relative to the total weight of the starch, of less than 30% by weight. Starch is mainly composed of amylose, that is to say linear chains of helical structure, which are only linked in an al, 4-glycosidic and amylopectin, highly branched structures, comprising a- 1,6-glycosides et al, 4-glycosides. The proportion of amyloidosis compared to amylopectin is highly dependent on the origin of the starch. There are plant species that produce lower amylose starch than others. Surprisingly, it has been found that the cleaning effect is particularly high when using starches having an amylose content of less than 30% by weight. In a particularly preferred manner, the homoglycan is chosen from the group consisting of corn starch, in particular starch derived from Zea Mays, tapioca starch and rice starch, in particular rice starch derived from the plant species Oryza Sativa. The homoglycan product particularly preferably contains rice starch derived from the plant species Oryza Sativa. These starches have been found to be particularly advantageous.

The origin of starch can play an important role, not only for the amylose content. The origin of starch also has an influence on the size and size distribution of starch particles and therefore on the size of the specific surface area of the particles. This also seems to be a cause of the fact that the starch extracted from the above-mentioned plant species is particularly well suited for use in dry shampoo without a propellant.

In a preferred embodiment of the present invention, the starch is a colored starch. Dry shampoos have the disadvantage that the powder leaves a gray veil on the hair. In particular, people with dark or even black hair thereby exclude the use of dry shampoos for themselves. The advantage of this preferred embodiment is to avoid gray haze on the hair. The starches used according to this preferred embodiment are prepared by mixing dyes with the starch. As the starch is in the form of particles, the dye molecules can be absorbed by the starch particles. The dyes can also be deposited on the surfaces of the starch particles.

The homoglycan product is preferably a product for the adsorption of a starch and a surfactant. Preferably, the surfactant is a polyorganosiloxane, preferably a polymethylsilsesquioxane, and / or the surfactant is a cationic surfactant, preferably an alkylammonium salt, more preferably an alkylammonium salt having at least one linear alkyl group. having 12 to 24 carbon atoms, even more preferably having 14 to 20 carbon atoms, and in particular a cetyltrimethylammonium salt. Any cosmetically acceptable cation is envisaged as a counterion to the alkylammonium cation, in particular to the cetyltrimethylammonium cation, but preferably the chloride or bromide ion. The surfactant can also be a colorant.

The preparation of the adsorption product is not critical. For example, it can be prepared by dispersing the starch in a medium in which the surfactant is dissolved.

The use of an adsorption product has several advantages. On the one hand, the adsorption of the surfactant changes the polarity of the surface of the homoglycan product. This has an influence on its fluidity and its tendency to form aggregates. On the other hand, the surfactant changes the receptivity of the homoglycan product to contaminants and hair fats. Polyorganosiloxanes, in particular polymethylsilsesquioxane, have proved to be particularly advantageous for solving the problem underlying the invention. These surfactants advantageously modify the polarity and make it possible to provide a product which has good cleaning performance.

Polyorganosiloxanes are also used as film-forming agents in hairdressing products. It has surprisingly been found that the use of polyorganosiloxanes, in particular polymethylsilsesquioxane as a surfactant on the starches used facilitates the shaping of the hair. The preferred embodiment therefore has the advantageous effect of improving the styling results of the hair. This effect can be explained by assuming that part of the ten-sioactive substance remains on the surface of the hair.

Alkylammonium salts are particularly advantageous because they hydrophobize the starch particles well and are at the same time particularly commercially available. This is particularly true for cetyltrimethylammonium salts.

In a preferred embodiment, the homoglycan product is (a) a first starch adsorption product, in particular rice starch, with the alkylammonium salt, in particular with the salt cetyltrimethylammonium, (b) a second starch adsorption product, in particular tapioca starch, with the polyorganosiloxane, in particular polymethylsilsesquioxane, or a mixture of (a) and (b), preferably a mixture of (a) and (b) with a weight ratio between (a) and (b) of 40: 1 to 5: 1, more preferably from 30: 1 to 10: 1.

This preferred embodiment, and in particular the use of two different adsorption products as homoglycan products, allows tailor-made adaptation of the desired properties. A rice starch adsorption product with an alkylammonium salt has proven to be advantageous for adjusting the hydrophobic nature of the particles and therefore the fluidity of the dry shampoo without a prepared propellant. An adsorption product of tapioca starch with a polyorganosiloxane is advantageous for the styling properties of hair treated with dry shampoo without propellant. The use of a mixture of these adsorption products is therefore advantageous for solving the problem underlying the invention. In particular, the more preferred mixture makes it possible to regulate advantageous properties in a targeted manner.

In a preferred dry shampoo without propellant, hydrophobically modified silicic acid is a product of the silylation of a silicic acid, in particular a pyrogenic silicic acid and an organosilicon compound. The silylation reactions of silicic acids with organosibiated compounds are known and used industrially on a large scale. The organosibiated compounds are covalently linked to the silicic acids by reacting the silanol groups of the silicic acids with the organosibiated compounds. In a preferred embodiment, the organosilicon compound is an alkylsiloxane or a silazane, the organosilicon compound preferably being an alkylsilazane, in particular hexamethyldisilazane. These substances are those which are best suited for the reaction. Hydrophobization with hexamethyldisilazane is the most widespread and the hydrophobized products are the best commercially available.

Mention may be made, for example, of Aerosil® R104 V, Aerosil® R106, Aerosil® R202, Aerosil® R805, Aerosil® R812, Aerosil® R812S, Aerosil® R972 and Aerosil® R8200

Degussa, as well as HDK® H2000, HDK® H2050 and HDK® H3004, and all Wackers. To summarize, the hydrophobically modified silicic acids are chosen from the compounds bearing the names INCI Silica Dimethyl Silylate (for example Aerosil® R792, Aerosil® R794), Silica Dimethicone Silylate (for example Aerosil® R202), Silica Caprylyl Silylate (for example Aerosil ® R805) and Silica Silylate (for example Aerosil® R812 or Aerosil® R816). It is particularly preferred to use the compounds bearing the name INCI Silica Silylate.

Pyrogenic silicic acids are particularly easy to obtain commercially. Their preparation is known and described in detail in the state of the art.

In a preferred embodiment, the homoglycan product is present in the dry shampoo without propellant in an amount ranging from 15 to 60% by weight, preferably from 20 to 50% by weight, more preferably 25 to 35% by weight, relative to the total weight of the dry shampoo without propellant.

These amounts have been found to be particularly advantageous for solving the problem underlying the invention.

In a preferred embodiment, the hydrophobically modified silicic acid is present in the dry shampoo without propellant in an amount ranging from 4 to 40% by weight, preferably from 8 to 25% by weight, more preferred from 10 to 20% by weight, relative to the total weight of the dry shampoo without propellant.

These quantities have been found to be particularly advantageous for solving the problem underlying the invention. In the preferred embodiments, which are characterized by the indicated amounts of hydrophobically modified homoglycan and silicic acid product, it should be taken into account that their sum does not always total 100. In such embodiments, d Other ingredients or liquid media are included in the dry shampoo without propellant.

In a particular embodiment of the present invention, the dry shampoo without propellant also contains a dye and / or pigments, in particular surface-modified pigments. This embodiment offers advantages for permanently dyed hair. As explained above, dry shampoos have the disadvantage that the powder can leave a gray veil on the hair. A dye or pigment can prevent this gray veil.

In a preferred embodiment of the present invention, the dry shampoo without propellant also contains a film-forming agent, preferably an acrylate-based polymer as film-forming agent, more preferably a copolymer consisting at least octylacrylamide, acrylic acid and butylaminoethyl methacrylate monomer units as film-forming agent. The term film-forming agent means polymers which, when dried, can leave a continuous film on the skin, hair or nails. Such film-forming agents can be used in a wide variety of cosmetic products, such as, for example, masks, makeup, hair fixers, hair sprays, hair gels, hair waxes, hair treatments, shampoos or nail polish. In the context of the present invention, the term “film-forming agent” is understood to mean in particular polymers which, when used at 0.05 to 20% by weight (relative to the total weight of the cosmetic product) of an aqueous solution, alcoholic or hydroalcoholic, are able to deposit on the hair in the form of a transparent polymer film. For the purposes of the present invention, acrylate-based film-forming agents are preferred.

This includes all polymers composed of acrylate or methacrylate monomer units. Preference is given to a copolymer composed of at least octylacrylamide, acrylic acid and butylaminoethyl methacrylate monomer units. This copolymer is a ter-polymer. It is also possible to use a copolymer composed of these three monomers and another monomer. An example that can be cited is the Amphomer® copolymer from AkzoNobel Surface Chemistry).

The film-forming agent is present in powder form in the dry shampoo without propellant. By incorporating the dry shampoo without propellant into the hair, one of the film-forming agents remains on the hair, thus guaranteeing an improvement in the styling, in particular a better hold of the hairstyle.

In another preferred embodiment of the present invention, the dry shampoo without propellant has, relative to the total weight of the dry shampoo without propellant, a water content less than or equal to 70% by weight, preferably less than or equal to 60% by weight, more preferably less than or equal to 50% by weight. The dry shampoo without propellant may also comprise an aqueous medium, for example a hydroalcoholic medium.

The fact that they are dry shampoos does not necessarily mean that they are purely powdered compositions. Reference is made here to what has been discussed above on dry shampoos. The use of water or aqueous solvents allows better incorporation into the hair. The ingredients can be better distributed in the hair and the styling of the hair is facilitated. The elimination or partial elimination of the dry shampoo without propellant - if desired - is also greatly improved.

A second object of the invention is a powder sprayer comprising a dry shampoo without propellant according to the invention.

Powder sprayers are known in the state of the art.

Dry shampoos without propellant can be dosed with a powder sprayer of this type for the application. The powder sprayers according to the invention offer better possibilities for giving the hair a fresher appearance even without ordinary complete washing and / or for temporarily shaping it.

In a preferred embodiment of the present invention, the dry shampoo without propellant is present in the powder sprayer in powder form. The advantage of this preferred embodiment resides in the fact that the composition of active principle, that is to say the dry shampoo without propellant, is a solid and that, consequently, the hair does not need to be wet for a cleaning operation.

A third object of the invention is a process for treating keratin fibers, in particular human hair, comprising the steps consisting in - applying the dry shampoo without propellant according to the invention to the keratin fibers, in particular on human hair, during a first step, and [0046] - treating the keratin fibers, in particular human hair, with a tissue and / or shaping the keratin fibers, during a second step.

According to this method, the hair can be cleaned using a dry shampoo without propellant and optionally temporarily shaped. In the first step, the dry shampoo without propellant is applied to the hair. Preferably, the dry shampoo without propellant is carefully mixed with the hands and left to act for a certain time. In a second step, the hair can be treated with a fabric. By treatment, it is preferably meant treatment or mechanical manipulation. By this operation, the dry shampoo without propellant is distributed evenly in the hair. The fabric can be a traditional towel, a disposable towel, etc.

Alternatively, the dry shampoo without propellant is distributed in the hair without prior treatment with a fabric and the hair is shaped or reshaped to obtain the desired hairstyle, in the second step. Preferred embodiments of the present invention include a homoglycan product comprising a polyorganosiloxane. This homoglycan product helps to shape the hair.

The method is in particular a method of dry cleaning and / or temporary shaping of keratin fibers, in particular human hair.

A fourth object of the invention is the use of a dry shampoo without propellant according to the invention for hair care, hair washing, in a coloring process and / or temporary shaping hair.
