Abstract

The invention relates to hairspray concentrates that are characterised by the use of specific film-forming components and special valves.

Description

Compact hairspray

The invention relates to a preparation for the treatment of keratin fibers, in particular human hair in the form of an aerosol spray, and the use of this preparation for the treatment of keratin fibers, in particular human hair.

Keratin fibers, especially human hair, are undergoing a variety of treatments nowadays. The treatments that serve to permanently or temporarily shape the hair play an important role. Temporary shapes that are supposed to provide a good hold without impairing the healthy appearance of the hair, such as, for example, its shine, can be achieved, for example, by hair sprays, hair waxes, blow dryer waves, etc.

Hair sprays usually contain synthetic polymers as a shaping component. Preparations which contain a dissolved or dispersed polymer can be applied to the hair by means of propellant gases or by a pump mechanism.

An attractive looking hairstyle is now generally considered an indispensable part of a well-groomed exterior. Due to current fashion trends, hairstyles are always considered chic, which for many hair types can only be built up using setting agents or can be maintained for a longer period of time up to several days.

BESTATIGUNGSKOPIE Hair treatment agents that give the hair more volume and hold are known. The cosmetic polymers usually used for this purpose show good strengthening properties in aqueous, aqueous-alcoholic or alcoholic solutions, which deform and strengthen the hair more or less well after use and which. can also give the hair more volume. Often, however, this effect does not last long and the desired volume effect is sometimes lost when you comb your hair. Many of the setting or bulking polymers often have undesirable side effects, which are noticeable in the fact that the treated hair has too rough a grip, too high a load or insufficient elasticity, or too many visible residues form on the hair. Inadequate washability after using these hair treatment products can also be a problem.

The firming active ingredients, which are typically polymeric ^compounds' can be used in usual hair cleansing or incorporated -konditioniermittel. In many cases, however, it is advantageous to use them in the form of special agents such as hair fixers, hair gels, hair waxes or hair sprays.

Setting hair treatment agents are used several times a day. The corresponding hair treatment agent is often always at hand by the consumer. However, the large volume of the usual aerosol cans is a major disadvantage. Although the aerosol cans could be reduced in volume, for example to cans of 100 ml or 50 ml, the content would then only be sufficient for a few applications. This is not acceptable to the consumer and also increases the amount of waste. This could be remedied by highly concentrated, at least twice to five times as highly concentrated hair spray formulations based on the content of setting polymers.

From EP 0 674 899 B1, deodorants in the form of aerosols are known, which for ecological reasons are packaged in as small containers as possible become. In order to maintain the spray rate in a concentrated deodorant spray in such a way that not too much product is discharged, the formulations were thickened. Polymers are used to formulate hair treatment agents. If these polymers are then concentrated, the formulation becomes significantly more viscous. This in turn leads to sticking and clogging of the valve. In addition, too much product is discharged, so that additional disadvantages, for example extreme stickiness, arise due to the excessive amount of product on the hair. Conversely, if the outlet opening of the valve is reduced accordingly, the valve becomes even more sticky and clogged.

The US Pat. No. 5,068,099 describes setting hair treatment agents which, when sprayed, only have an average droplet size of approximately 60 μm. However, the spray rate is significantly increased compared to conventional hair sprays. In addition, the water content in these formulations is limited to a maximum of 10% by weight. The problem of sticking the valves remains. Furthermore, the excessive product release also leads to sticking to the hair. No steady consolidation is achieved. The low water content on the other hand means a high content of volatile organic compounds. In modern recipes that are common today, however, the water content is up to 45% by weight.

There is therefore still the task of developing corresponding highly concentrated agents which, with regard to the application properties, for example the long-lasting hold of the hairstyle, in particular a long-lasting (up to days) high volume, the fullness, the easy combability of the wet and dry hair Forms of hairstyles, especially in the area of the hair tips, the shine, the velvety, smooth feel of the hair, the possibility of shaping hairstyles and a short drying time with setting hair care products, as well as the flexibility of the shaped hairstyle and the washability of the compositions, the expectations set by the consumer fulfill. In addition, the consumer desires a small package that can be easily transported and is therefore available everywhere. Despite the desired small packaging, however, the content should suffice for numerous applications and correspond to or exceed the number of applications of a commercially available hairspray.

It has now been found that the object is achieved by a setting hair treatment composition which is composed of: (A) at least 3.0% by weight of at least> one film-forming and / or setting polymer, (B) 10.0 to 80% by weight. % of a protic solvent and (C) 20 to 90% by weight of a blowing agent, characterized in that the mean droplet size of this composition when sprayed is less than 40 μm.

The film-forming and / or setting polymer (A) in the agent according to the invention is preferably in an amount from 3.0 to 40% by weight, particularly preferably from 3.0 to 30% by weight, very particularly preferably in an amount from 3.0 to Contain 20 percent by weight. Of course, several film-forming and / or solid polymers can also be contained in the agent according to the invention. These film-forming and / or setting polymers can be both permanent and temporary cationic, anionic, nonionic or amphoteric. Furthermore, the present invention also includes the knowledge that when at least two film-forming and / or setting polymers are used, these can of course have different charges. It can be preferred according to the invention if an ionic film-forming and / or setting polymer is used together with an amphoteric and / or non-ionic film-forming and / or setting polymer. The use of at least two oppositely charged film-forming and / or setting polymers is also preferred. In the latter case, a special embodiment can again have at least one contain further amphoteric and / or nonionic film-forming and / or setting polymer.

Since polymers are often multifunctional, their functions cannot always be clearly and unambiguously distinguished. This applies in particular to film-forming and setting polymers. Nevertheless, some film-forming polymers should be described as examples. However, reference is explicitly made here to the fact that both film-forming and setting polymers are essential in the context of the present invention. Since both properties are also not completely independent of one another, the term “setting polymers” is always also understood to mean “film-forming polymers” and vice versa.

Film formation is one of the preferred properties of the film-forming polymers. Film-forming polymers are understood to mean those polymers which, when dried, leave a continuous film on the skin, hair or nails. Such film formers can be used in a wide variety of cosmetic products such as, for example, face masks, make-up, hair fixatives, hair sprays, hair gels, hair waxes, hair treatments, shampoos or nail varnishes. Polymers which have sufficient solubility in alcohol or water / alcohol mixtures to be present in the agent according to the invention in completely dissolved form are particularly preferred. The film-forming polymers can be synthetic or natural in origin.

According to the invention, film-forming polymers are furthermore understood to mean those polymers which, when used in 0.01 to 20% aqueous, alcoholic or aqueous-alcoholic solution, are able to deposit a transparent polymer film on the hair. The film-forming polymers can be charged anionically, amphoterically, non-ionically, permanently cationically or temporarily cationically. Suitable synthetic, film-forming, hair-fixing polymers are homopolymers or copolymers which are composed of at least one of the following monomers: vinylpyrrolidone, vinylcaprolactam, vinyl esters such as, for example, vinyl acetate, vinyl alcohol, acrylamide, methacrylamide, alkyl and dialkyl acrylamide, alkyl and dialkyl methacrylamide, alkyl acrylate, Alkyl methacrylate, propylene glycol or ethylene glycol, the alkyl groups of these monomers preferably being C1 to C7 alkyl groups, particularly preferably C1 to C3 alkyl groups. Homopolymers of vinyl caprolactam, vinyl pyrrolidone or N-vinyl formamide are suitable, for example. Other suitable synthetic film-forming, hair-fixing polymers are, for example, copolymers of vinylpyrrolidone and vinyl acetate, terpolymers of vinylpyrrolidone, vinyl acetate and vinyl propionate. Polyvinylpyrrolidone and polyvinylpyrrolidoneΛ ethyl acetate copolymers are particularly preferred.

Substances which further impart hydrophobic properties to the hair are preferred here because they reduce the tendency of the hair to absorb moisture, that is to say water. This reduces the sagging of the hair strands and thus ensures a long-lasting hair style build-up and maintenance. The so-called curl retention test is often used as a test method for this. These polymeric substances can continue to be successfully incorporated into leave-on and rinse-off hair treatments or shampoos. Since polymers are often multifunctional, that is to say they have several effects which are desired in terms of application technology, numerous polymers can be found in several groups which are classified according to the mode of action, as also in the CTFA manual. Because of the importance of the setting polymers, they should be listed explicitly in the form of their INCI names. This list of the polymers which are particularly preferably to be used according to the invention therefore naturally also includes the cationic polymers.

Acrylates / t-butylacrylamide copolymers, octylacrylamides / acrylates / butylaminoethyl methacrylate copolymers are very particularly preferred,

Polyurethane-1, polyvinylcaprolactam and VPΛ / A copolymer. Amphoteric polymers can also be used as polymers. The term amphoteric polymers includes both those polymers which contain both free amino groups and free -COOH or SO ₃ H groups in the molecule and are capable of forming internal salts, and also zwitterionic polymers which contain quaternary ammonium groups and -COO in the molecule Contain ^" - or -SO ₃ ^" groups, and summarize those polymers which contain - COOH or SO ₃ H groups and quaternary ammonium groups.

An example of the present invention amphopolymer suitable is that available under the name Amphomer ^® acrylic resin which is a copolymer of tert-butylaminoethyl methacrylate, N- (1, 1, 3,3-tetramethylbutyl) -acrylamide and two or more monomers from the group of acrylic acid, Methacrylic acid and its simple esters.

Amphoteric polymers which are preferably used are those polymers which essentially consist of one another

(a) Monomers with quaternary ammonium groups of the general formula (G3-1), R ¹ -CH = CR ² -CO-Z- (C _n H _2n ) -N ⁽⁺⁾ R ³ R ⁴ R ⁵ A ^H (G3- I) in which R ¹ and R ² independently of one another represent hydrogen or a methyl group and R ³ , R ⁴ and R ⁵ independently of one another are alkyl groups having 1 to 4 carbon atoms, Z is an NH group or an oxygen atom, n is an integer from 2 to 5 and A is the anion of an organic or inorganic acid, and

(b) monomeric carboxylic acids of the general formula (G3-II), R ⁶ -CH = CR ⁷ -COOH (G3-II) in which R ⁶ and R ^{7 are} independently hydrogen or methyl groups.

These compounds can be obtained either directly or in salt form, by neutralizing the polymers, for example with an alkali metal hydroxide will be used according to the invention. With regard to the details of the production of these polymers, reference is expressly made to the content of the German published application 39 29 973. Those polymers in which monomers of type (a) are used, in which R ³ , R ⁴ and R ^{5 are} methyl groups, Z is an NH group and A ^{w is} a halide, methoxysulfate or ethoxysulfate ion, are very particularly preferred ;, Acrylamidopropyl-trimethyl-ammonium chloride is a particularly preferred Monbmeres (a). Acrylic acid is preferably used as monomer (b) for the polymers mentioned.

Finally, the composition according to the invention can be influenced in a targeted manner, in particular with regard to the setting, softening and antistatic effect, if anionic polymers are also formulated. The anionic polymers are, inter alia, anionic polymers which have carboxylate and / or sulfonate groups. Examples of anionic monomers from which such polymers can consist are acrylic acid, methacrylic acid, crotonic acid, maleic anhydride and 2-acrylamido-2-methylpropanesulfonic acid. The acidic groups can be present in whole or in part as sodium, potassium, ammonium, mono- or triethanolammonium salt. Preferred monomers are 2-acrylamido-2-methylpropanesulfonic acid and acrylic acid.

Anionic polymers which contain 2-acrylamido-2-methylpropanesulfonic acid as the sole or co-monomer have proven to be very particularly effective, the sulfonic acid group being able to be present in whole or in part as the sodium, potassium, ammonium, mono- or triethanolammonium salt ,

Anionic polymers which are also suitable according to the invention include a .:

Vinyl acetate / crotonic acid copolymers, such as are commercially available for example under the names Resyn ^® (National Starch), Luviset ^® (BASF) and Gafset ^® (GAF). VinylpyrrolidonΛ / inylacrylate copolymers, available for example under the trademark Luviflex ^® (BASF). A preferred polymer is that available under the name Luviflex VBM-35 ^® (BASF) vinylpyrrolidone / acrylate terpolymers.

Acrylic acid / ethyl acrylate N-tert-butyl acrylamide terpolymers, which are sold, for example, under the name Ultrahold ^® strong (BASF).

Another very particularly preferred group of polymers are polyurethanes. The polyurethanes consist of at least two different types of monomers, a compound (V1) with at least 2 active hydrogen atoms per molecule and - a di- or polyisocyanate (V2).

The compounds (V1) can be, for example, diols, triols, diamines, triamines, polyetherols and polyesterols. The compounds with more than 2 active hydrogen atoms are usually used only in small amounts in combination with a large excess of compounds with 2 active hydrogen atoms.

Examples of compounds (V1) are ethylene glycol, 1,2- and 1,3-propylene glycol, butylene glycols, di-, tri-, tetra- and poly-ethylene and propylene glycols, copolymers of lower alkylene oxides such as ethylene oxide, propylene oxide and butylene oxide, Ethylenediamine, propylenediamine, 1, 4-diaminobutane,

Hexamethylenediamine and α, ω-diamines based on long-chain alkanes or polyalkylene oxides.

Polyurethanes in which the compounds (V1) are diols, triols and polyetherols can be preferred according to the invention. In particular polyethylene glycols and polypropylene glycols with molecular weights between 200 and 3000, in particular between 1600 and 2500, have proven to be particularly suitable in individual cases.

Polyesterols are usually obtained by modifying the compound (V1) with dicarboxylic acids such as phthalic acid, isophthalic acid and adipic acid.

The compounds (V2) used are predominantly hexamethylene diisocyanate, 2,4- and 2,6-toluene diisocyanate, 4,4'-methylene di (phenyl isocyanate) and in particular isophorone diisocyanate.

Furthermore, the polyurethanes used according to the invention can also contain building blocks such as, for example, diamines as chain extenders and hydroxycarboxylic acids. Dialkylolcarboxylic acids such as dimethylolpropionic acid are particularly suitable hydroxycarboxylic acids. With regard to the other building blocks, there is no fundamental restriction as to whether the building blocks are nonionic, anionic or cationic.

With regard to further information on the structure and manufacture of the polyurethanes, reference is expressly made to the articles in the relevant reference works such as Römpps chemistry lexicon and Ullmanns encyclopedia of technical chemistry.

Polyurethanes which can be characterized as follows have proven particularly suitable according to the invention in many cases:

- only aliphatic groups in the molecule

- No free isocyanate groups in the molecule

- Polyether and polyester polyurethanes

- anionic groups in the molecule.

It has also proven to be advantageous in some cases if the polyurethane is not dissolved in the system but is dispersed in a stable manner. Furthermore, it has proven to be advantageous for the preparation of the agents according to the invention if the polyurethanes are not mixed directly with the other components, but instead are introduced in the form of aqueous dispersions. Such dispersions usually have a solids content of approximately 20-50%, in particular approximately 35-45%, and are also commercially available.

An inventively particularly preferred polyurethane is available under the trade name Luviset.RTM ^® PUR (BASF).

In a further embodiment, the agents according to the invention can contain nonionic polymers.

Suitable nonionic polymers include: vinyl pyrrolidone / Vinylester copolymers, as are marketed, for example under the trademark Luviskol ^® (BASF). Luviskol ^® VA 64 and Luviskol ^® VA 73, each vinylpyrrolidoneΛ inylacetate copolymers, are also preferred nonionic polymers.

- polyvinylpyrrolidones, as, for example, sold under the name Luviskol ^® (BASF).

- siloxanes. These siloxanes can be both water-soluble and water-insoluble. Both volatile and non-volatile siloxanes are suitable, non-volatile siloxanes being understood to mean those compounds whose boiling point is above 200 ° C. at normal pressure. Preferred siloxanes are polydialkylsiloxanes, such as, for example, polydimethylsiloxane, polyalkylarylsiloxanes, such as, for example, polyphenylmethylsiloxane, ethoxylated polydialkylsiloxanes and polydialkylsiloxanes which contain amine and / or hydroxyl groups.

- Glycosidically substituted silicones according to EP 0612759 B1.

It is also possible according to the invention that the preparations used contain several, in particular two different polymers of the same charge and / or each contain an ionic and an amphoteric and / or non-ionic polymer.

Other preferred polymers are all polymers which in the "International Cosmetic Ingredient Dictionary and Handboo.k" (seventh edition 1997, The Cosmetic, Toiletry, and Fragrance Association 1101 17 ^th Street, NW, Suite 300, Washington, DC 20036-4702 ) are mentioned as polymers in one of the chapters on polymers such as "film formers" or "hair fixatives" and are commercially available. Reference is expressly made to this document and the sections cited from it.

The agent according to the invention is preferably made up in an aqueous * alcoholic or in an aqueous alcoholic medium with preferably at least 10% by weight of water. In particular, the lower alcohols with 1 to 4 carbon atoms usually used for cosmetic purposes, such as ethanol and isopropanol, can be included as alcohols. The agent according to the invention can be present in a pH range from 2 to 11. The pH range between 2 and 8 is particularly preferred.

Organic solvents or a mixture of solvents with a boiling point below 400 ° C. can be present as additional co-solvents in an amount of 0.1 to 15 percent by weight, preferably 1 to 10 percent by weight. Unbranched or branched hydrocarbons such as pentane, hexane, isopentane and cyclic hydrocarbons such as cyclopentane and cyclohexane are particularly suitable as additional co-solvents. Further, particularly preferred water-soluble solvents are glycerol, ethylene glycol and propylene glycol in an amount of up to 30 percent by weight.

The third component of the preparations according to the invention is the blowing agent.

Propellant gases must be used to use the compositions according to the invention as aerosol sprays. The preferred according to the invention Propellants are selected from hydrocarbons with 3 to 5 carbon atoms, such as propane, n-butane, iso-butane, n-pentane and iso-pentane, dimethyl ether, carbon dioxide, nitrous oxide, fluorocarbons and chlorofluorocarbons and mixtures of these substances. Very particularly preferred propellant gases are propane, butane, isobutane, pentane, isopentane, dimethyl ether and the mixtures of these aforementioned propellant gases. Most preferred propellant gases according to the invention are the mixtures of dimethyl ether with hydrocarbons. Preferred among the group of hydrocarbons as propellants are n-butane and propane.

The blowing agent is advantageously selected so that it can simultaneously serve as a solvent for other ingredients such as oil and wax components, the fatty substances (D). The blowing agent can then serve as a solvent for these latter components if at least 0.5% by weight, based on the blowing agent, of the latter is soluble in it at 20 ° C.

According to a preferred embodiment, the preparations according to the invention contain the hydrocarbons mentioned or mixtures of the hydrocarbons mentioned with dimethyl ether as the sole blowing agent. However, the invention also expressly includes the use of blowing agents of the chlorofluorocarbon type, but especially the fluorocarbons.

The propellant gases are present in amounts of 5-98% by weight, preferably 10-98% by weight and particularly preferably 20-98% by weight, very particularly preferably from 40 to 98% by weight, in each case based on the total aerosol composition ,

The compositions according to the invention can be packaged in commercially available aerosol cans. The cans can be made of tinplate or aluminum. Furthermore, the cans can be coated on the inside in order to keep the risk of corrosion as low as possible. If the compositions according to the invention are used as a non-aerosol spray application, there is of course no propellant gas. However, the spray heads must always be selected according to the required spray rates.

The cans are equipped with a suitable spray head. Depending on the spray head, discharge rates based on fully filled cans can range from 0.1 g / s to 5.0 g / s. The spray rate is determined in such a way that an aerosol can filled with propellant gas and the appropriate composition and sealed with the relevant valve is first weighed at room temperature (about 23 ° C.). The can and its contents are shaken vigorously by hand 10 times so that the contents mix well. Then the valve of the vertical can is actuated for 10 s. Then weigh again. The process is carried out 5 times in a row and the statistical mean is formed from the results. The difference between the two weighings is the spray rate per 10 s. From this, the spray rate per second can be determined by simple division. In the case of non-aerosols, the spray mechanism is actuated 10 times. In the latter case, the spray rate is to be understood as the average amount applied per burst (pump burst). Spray rates of 0.1 to 0.5 g / s are preferred. Spray rates of 0.1 to 0.4 g / s are particularly preferred.

Another characteristic influence on the efficiency and formulability as a compact spray is the spray pattern. The spray pattern is decisively influenced by the valve and its nature. If, for example, the film former in a hairspray formulation is increased up to five times compared to a conventional formulation, in addition to the increased viscosity of the formulation to be observed and avoided, the spray rate already discussed is also essential for the formulation to be observed. In addition, however, the spray pattern, that is to say the opening cone of the valve, and the droplet size must also be taken into account. If the opening cone has an opening angle that is too large, then the product is applied to a hair surface that is too small at a usual distance of the spray can from the user's head of about 10 to 40 cm. This leads to a change in the effectiveness of the composition. There are either forgiveness due to excessive amounts of product or an insufficient strengthening effect due to insufficient application of product. In the latter case, the opening cone is too large, so that an excessively large hair surface is treated with the composition. It has now been shown that the opening cone should ideally be between 25 ° and 65 °. An angle of 30 ° to 60 ° is preferred. Opening cones between 35 ° and 50 are very particularly preferred

The influence of the droplet size is as follows: If the droplets are too large, the formulation is not evenly distributed on the hair, so that too many product quantities occur in many places. On the other hand, product quantities are too small. Numerous tests have now shown that the average droplet size should ideally be less than 50 μm. Droplet sizes smaller than 45 μm are preferred. Droplet sizes smaller than 40 μm are very particularly preferred.

The droplet size is determined using a laser diffraction meter of the type Masterizer, Series 2600 Droplet and Particle Size Analyzer from Malvern. For this purpose, the sample is sprayed at a defined distance through the light beam from the laser and the particle size distribution is determined using laser diffraction.

The viscosity of the formulation to be sprayed can also have an influence, depending on the concentration of the film-forming polymers. At the same time, however, valves are also known, with the help of which even gels can be sprayed. However, it can be preferred according to the invention if the viscosities of the Recipes less than 5000 mPas measured according to Brookfield with spindle 3 at 20 rpm and 25 ° C. The viscosities of the recipes are measured before the addition of propellant. It can be particularly preferred if the viscosities are less than 2500 mPas and very particularly preferably less than 1000 mPas.

Finally, in addition to the targeted selection of the film-forming polymers, the problem of the valves sticking can also be positively influenced by appropriate processing, material selection and / or pretreatment of the valves. It is essential that all parts of the valve that come into contact with the composition have the smoothest possible surface. The smoother the surface, the less the composition can adhere to it through adhesion. This counteracts sticking of the nozzle. The achievement of particularly smooth surfaces is known to the person skilled in the art, for example by executing the surface in the form of nanoparticles in order to achieve a lotus flower effect or polishing the surfaces, for example electropolishing.

When applying the composition according to the invention, the hair should be shaped into a specific hairstyle. To do this, it may be necessary to positively influence the hair structure and condition. For example, it can be advantageous if the combing resistances are low during the build-up of the hairstyle. Furthermore, the hairstyle should show a certain shine or colored shimmering effects. The hair is said to give a vital impression when styled. For this it is necessary to incorporate care substances into the composition according to the invention.

Suitable compounds in the context of the present invention as hair care compounds are described in more detail below. To the natural and synthetic cosmetic oil bodies (D4), which the

The effect of the composition according to the invention can be increased, for example:

- vegetable oils. Examples of such oils are sunflower oil, olive oil, soybean oil, rapeseed oil, almond oil, jojoba oil, orange oil, wheat germ oil, peach seed oil and the liquid components of coconut oil. Other triglyceride oils such as the liquid portions of beef tallow and synthetic triglyceride oils are also suitable.

The total amount of oil and fat components in the agents according to the invention is usually 0.1-50% by weight, based on the total agent. Quantities of 0.1-30% by weight are preferred according to the invention.

Furthermore, in a preferred embodiment of the invention, the use of UV filters (I) can give further advantages with regard to the structure of the hair and thus advantages in terms of combability, gloss or volume. The hair is protected from the effects of UV light with the help of the UV filter.

Preferred UV filters are those whose molar extinction coefficient at the absorption maximum is above 15,000, in particular above 20,000.

Furthermore, it has been found that in structurally similar UV filters, the water-insoluble compound has, in the context of the teaching according to the invention, the higher activity than those water-soluble compounds which differ from it by one or more additional ionic groups. Within the scope of the invention, water-insoluble are UV filters which do not dissolve in water at 20 ° C. by more than 1% by weight, in particular not more than 0.1% by weight. Furthermore, these compounds should be at least 0.1, in particular at least 1% by weight soluble in conventional cosmetic oil components at room temperature). The use of water-insoluble UV filters can therefore be preferred according to the invention. According to a further embodiment of the invention, those UV filters are preferred which have a cationic group *, in particular a quaternary ammonium group.

These UV filters have the general structure U - Q.

The structural part U stands for a group that absorbs UV rays. This

In principle, a group can be derived from the known UV filters mentioned above, which can be used in the cosmetics sector, in which a group in which

Usually a hydrogen atom of the UV filter is replaced by a cationic group Q, in particular with a quaternary amino function.

Compounds, can vary from ¹ to derive which the structural moiety U, for example,

- substituted benzophenones,

p-aminobenzoic acid ester,

- diphenylacrylic acid ester,

- cinnamic acid esters,

- salicylic acid esters,

- benzimidazoles and

o-aminobenzoic acid esters.

Structural parts U which are derived from cinnamic acid amide or from N, N-dimethylaminobenzoic acid amide are preferred according to the invention.

The structural parts U can in principle be selected so that the absorption maximum of the UV filter can be both in the UVA (315-400 nm) - and in the UVB (280-315nm) - or in the UVC (<280 nm) range. UV filters with an absorption maximum in the UVB range, in particular in the range from approximately 280 to approximately 300 nm, are particularly preferred.

Furthermore, the structural part U, also depending on the structural part Q, is preferably chosen so that the molar extinction coefficient of the UV filter is on Absorption maximum is above 15,000, in particular above 20,000.

The structural part Q preferably contains a quaternary ammonium group as the cationic group. In principle, this quaternary ammonium group can be directly connected to the structural part U, so that the structural part U is one of the four substituents of the positively charged nitrogen atom. However, one of the four substituents on the positively charged nitrogen atom is preferably a group, in particular an alkylene group having 2 to 6 carbon atoms, which functions as a connection between the structural part U and the positively charged nitrogen atom.

Advantageously, the group Q has the general structure - (CH ₂ ) χ-N ⁺ R ¹ R ² R ³ X ^" , in which x represents an integer from 1 to 4, R ¹ and R ² independently of one another represent Cι- ₄ -alkyl groups, R ³ stands for one

or a benzyl group and X ^" for a physiologically acceptable anion. In the context of this general structure, x preferably stands for the number 3, R ¹ and R ² each for a methyl group and R ³ either for a methyl group or a saturated or unsaturated, linear or branched hydrocarbon chain with 8 to 22, in particular 10 to 18, carbon atoms.

Physiologically compatible anions are, for example, inorganic anions such as halides, in particular chloride, bromide and fluoride, sulfate ions and phosphate ions, and organic anions such as lactate, citrate, acetate, tartrate, methosulfate and tosylate.

Two preferred UV filters with cationic groups are the commercially obtainable compounds Zimtsäureamidopropyl- trimethylammonium chloride (lncroquat ^® UV-283) and dodecyl tosylate (Escalol ^® HP 610). Of course, the teaching according to the invention also includes the use of a combination of several UV filters. In the context of this embodiment, the combination of at least one water-insoluble UV filter with at least one UV filter with a cationic group is preferred.

The UV filters (I) are usually contained in the agents used according to the invention in amounts of 0.1-5% by weight, based on the total agent. Amounts of 0.4-2.5% by weight are preferred.

The effect of the combination according to the invention can be further increased by a 2-pyrrolidinone-5-carboxylic acid and its derivatives (J). Another object of the invention is therefore the use of the active ingredient in combination with derivatives of 2-pyrrolidinone-5-carboxylic acid. Preferred are the sodium, potassium, calcium, magnesium or ammonium salts in which the ammonium ion carries one to three Q to C ₄ alkyl groups in addition to hydrogen. The sodium salt is very particularly preferred. The amounts used in the agents according to the invention are 0.05 to 10% by weight, based on the total agent, particularly preferably 0.1 to 5 and in particular 0.1 to 3% by weight.

It has also proven to be advantageous to add vitamins, provitamins and vitamin precursors and their derivatives (K) to the compositions according to the invention. It may be preferred to select only those vitamins, provitamins and vitamin precursors and their derivatives that are only soluble in alcohol and / or in alcohol / water mixtures.

Vitamins, pro-vitamins and vitamin precursors which are usually assigned to groups A, B, C, E, F and H are preferred according to the invention.

The group of substances called vitamin A includes retinol (vitamin Ai) and 3,4-didehydroretinol (vitamin A ₂ ). The ß-carotene is that Provitamin of retinol.

- Vitamin B ₅ (pantothenic acid, panthenol and pantolactone). Within this group, panthenol and / or pantolactone is preferably used. Derivatives of panthenol which can be used according to the invention are, in particular, the esters and ethers of panthenol and cationically derivatized panthenols. Individual representatives are, for example, panthenol triacetate, panthenol monoethyl ether and its monoacetate and the cationic panthenol derivatives disclosed in WO 92/13829. The compounds of the vitamin B ₅ type mentioned are preferably present in the agents used according to the invention in amounts of 0.05-10% by weight, based on the total agent. Amounts of 0.1-5% by weight are particularly preferred.

- Vitamin B ₆ (pyridoxine, pyridoxamine and pyridoxal).

Vitamin C (ascorbic acid). Vitamin C is preferably used in the agents used according to the invention in amounts of 0.1 to 3% by weight, based on the total agent. Use in the form of the palmitic acid ester, the glucosides or phosphates can be preferred. Use in combination with tocopherols may also be preferred. Vitamin E (tocopherols, especially α-tocopherol). Tocopherol and its derivatives, which include in particular the esters such as acetate, nicotinate, phosphate and succinate, are preferably present in the agents used according to the invention in amounts of 0.05-1% by weight, based on the total agent ,

Vitamin F. The term “vitamin F” usually means essential fatty acids, in particular linoleic acid, linoleic acid and arachidonic acid.

Vitamin H. The compound (3aS, 4S, 6aR) -2-oxohexa- hydrothienol [3,4-] imidazole-4-valeric acid is referred to as vitamin H, but for which the trivial name biotin has now become established. Biotin is contained in the agents used according to the invention preferably in amounts of 0.0001 to 1.0% by weight, in particular in amounts of 0.001 to 0.01% by weight.

Preferably, the iviinei vuamiπe used according to the invention contain provitamins and vitamin precursors from groups A, B, E and H.

Panthenol, pantolactone, pyridoxine and its derivatives as well as nicotinamide and biotin are particularly preferred.

Finally, the effect can also be increased by the combined use with plant extracts (L).

These extracts are usually produced by extracting the entire plant. In individual cases, however, it may also be preferred to produce the extracts exclusively from flowers and / or leaves of the plant.

With regard to the plant extracts which can be used according to the invention, reference is made in particular to the extracts which are published in page 44 of the 3rd edition of the guide to the declaration of ingredients of cosmetic products are listed by the Industrieverband Körperpflege- und Waschmittel eV (IKW), Frankfurt.

According to the invention, the extracts from green tea, oak bark, nettle, witch hazel, valerian, hops, He.nna, chamomile, burdock root, horsetail, hawthorn, linden flowers, mandei, aloe vera, spruce needles, horse chestnut, sandalwood, juniper, coconut, mango , Apricot, lime, wheat, kiwi, melon, orange, grapefruit, sage, rosemary, birch, mallow, cuckoo flower, quendella, yarrow, thyme, lemon balm, squirrel, coltsfoot, marshmallow, meristem, ginseng and ginger root preferred.

The extracts from green tea, oak bark, nettle, witch hazel, hops, valerian, chamomile, burdock root, horsetail, linden flowers, almond, aloe vera, coconut, mango, apricot, lime, wheat, kiwi, melon, orange, grapefruit are particularly preferred. Sage, rosemary ,. Birch, cuckoo flower, quendel, yarrow, hake, meristem, ginseng and ginger root.

The extracts from green tea, valerian, almond, aloe vera, coconut, mango, apricot, lime, wheat, kiwi and melon are particularly suitable for the use according to the invention.

Water, alcohols and mixtures thereof can be used as extractants for the production of the plant extracts mentioned. Among the alcohols, lower alcohols such as ethanol and isopropanol, but in particular polyhydric alcohols such as ethylene glycol and propylene glycol, are preferred, both as the sole extracting agent and as a mixture with water. Plant extracts based on water / propylene glycol in a ratio of 1:10 to 10: 1 have proven to be particularly suitable.

According to the invention, the plant extracts can be used both in pure and in diluted form. Unless they are used in diluted form they usually contain about 2 to 80% by weight of active substance and the extractant or mixture of extractants used in their extraction as a solvent.

Furthermore, it may be preferred to use mixtures of several, in particular two, different plant extracts in the agents according to the invention.

In addition, it can prove to be advantageous if, in addition to the combination according to the invention, penetration aids and / or swelling agents (M) are present. These auxiliaries ensure better penetration of active ingredients into the keratin fiber or help swell the keratin fiber. These include, for example, urea and urea derivatives, guanidine and its derivatives, arginine and its derivatives, water glass, imidazole and its derivatives, histidine and its derivatives, benzyl alcohol, glycerol, glycol and glycol ethers, propylene glycol and propylene glycol ethers, for example propylene glycol monoethyl ether, carbonates, hydrogen carbonates Diols and triols, and in particular 1,2-diols and 1,3-diols such as, for example, 1,2-propanediol, 1,2-pentanediol, 1,2-hexanediol, 1,2-dodecanediol, 1,3-propanediol, 1st , 6-hexanediol, 1, 5-pentanediol, 1, 4-butanediol.

When the preparations are perceived, in particular as a result of aesthetic packaging, possibly in conjunction with aromatic fragrance notes, the consumer may associate the composition according to the invention with a stimulant. In principle, this association, in particular in children, means that oral intake or swallowing of the composition cannot be completely ruled out. In a preferred embodiment, the compositions according to the invention therefore contain a bitter substance in order to prevent swallowing or accidental ingestion. Bitter substances are preferred according to the invention which are soluble in water at 20 ° C. to at least 5 g / l. With regard to an undesirable interaction with fragrance components possibly contained in the composition according to the invention, in particular a change in the fragrance note perceived by the consumer, the ionogenic bitter substances have proven to be superior to the nonionic, ionogenic bitter substances, preferably consisting of organic cation (s) and organic anion (s) are therefore preferred for the preparations according to the invention.

Quaternary ammonium compounds which contain an aromatic group both in the cation and in the anion are particularly suitable as bitter substances. One such compound is commercially available for example under the trademark Bitrex ^® and Indige-stin ^® available benzyldiethyl ((2,6 Xylylcarbamoyl) methyl) ammonium benzoate. This compound is also known as Denatonium Benzoate.

The bitter substance is present in the compositions according to the invention in amounts of 0.0005 to 0.1% by weight, based on the shaped body. Quantities of 0.001 to 0.05% by weight are particularly preferred.

Other active ingredients, auxiliaries and additives are, for example

hair-conditioning compounds such as phospholipids, for example soy lecithin, egg lecithin and cephalins, and silicone oils,

- perfume oils, dimethyl isosorbide and cyclodextrins,

Solvents and intermediates such as ethanol, isopropanol, ethylene glycol, propylene glycol, glycerin and diethylene glycol,

Pearlescent agents such as ethylene glycol mono- and distearate and PEG-3 distearate,

- pigments,

Propellants such as propane-butane mixtures, N ₂ O, dimethyl ether, CO ₂ and air,

- antioxidants.

With regard to further optional components and the amounts of these components used, reference is expressly made to the relevant manuals known to the person skilled in the art, e.g. B. referred to the above monograph by KH Schrader. ¹

Sprays, aerosols and foam aerosols are suitable. The pH of these preparations can in principle be between 2 and 11. It is preferably between 3 and 10, values from 5 to 8 being particularly preferred. Virtually any acid or base that can be used for cosmetic purposes can be used to adjust this pH.

Food acids are usually used as acids. Edible acids are those acids that are ingested as part of normal food intake and have positive effects on the human organism. Edible acids are, for example, acetic acid, lactic acid, tartaric acid, citric acid, malic acid, ascorbic acid and gluconic acid. In the context of the invention, the use of citric acid and lactic acid is particularly preferred. Preferred bases are ammonia, alkali hydroxides, monoethanolamine, triethanolamine, aminomethylpropanol, triisopropanolamine, and N, N, N ', N'-tetrakis (2-hydroxypropyl) ethylenediamine. These bases are also used to neutralize or partially neutralize the fixing and / or fixing polymers, if this is necessary.

A very particularly preferred form of application is an aerosol and / or non-aerosol spray application. Here, the agent according to the invention Sprayed using a suitable mechanically operated spraying device. Mechanical spray devices are to be understood as devices which enable the spraying of a liquid without using a propellant. A suitable mechanical spray device can be, for example, a spray pump or an elastic container provided with a spray valve, in which the cosmetic agent according to the invention is filled under pressure, the elastic container expanding and from which the agent continuously as a result of the contraction of the elastic container when the spray valve is opened is used.

To design the invention as an aerosol application, any corresponding aerosol valve can be used which enables the spray rate according to the invention and / or the corresponding droplet sizes. It can be advantageous here if the valve opening has a diameter of at most 0.4 mm. An opening of 0.35 mm is preferred. Valve openings of at most 0.3 mm are very particularly preferred. Corresponding aerosol valves are described, for example, in the patents US Pat. No. 4,152,416, US Pat. No. 3,083,917, US Pat. No. 3,083,918, US Pat. No. 3,444,258. Such valves are commercially available, for example, from Seaquist Perfect Dispensing GmbH or Coster Technologie Speciali s.p.a. can be obtained. In a very particularly preferred embodiment, the Ariane M valve from Seaquist is used as the valve. It can be particularly preferred if this valve is used together with a special throttling. The throttling is either in the star of the valve or in the spray head. This is shown graphically in drawing I. Another particularly preferred embodiment uses a valve with a side bore as a valve, such as is offered by the Coster company under the type designation K 125 SL 184/3/6.

For further development, express reference is made to Andreas Domsch, "The Cosmetic Preparations", Volume II, Chapter 4, Aerosols, page 259, following, Publishing House for the Chemical Industry, H. Ziolkowsky Kg, Augsburg, 1992. According to the invention, it goes without saying that the aerosol container can be made of aluminum monobloc cans, but also of plastics such as PET or glass.

Any spray pump which enables the spray rate according to the invention can be used to design the invention as a non-aerosol. Corresponding systems are commercially available, for example, under the name Calmar Mark II from Calmar Inc.
