Description

"Hair Cosmetic Preparations"

Field of the Invention

The invention relates to hair cosmetic preparations for cleaning and / or grooming hair which contain a special binary combination of active ingredients.

State of the art

Today human hair is treated in a variety of ways with hair cosmetic preparations. These include cleaning the hair with shampoos and shower preparations, as well as bleaching, dyeing and shaping the hair with waving agents, tinting agents and styling preparations.

However, almost all types of hair treatment can be accompanied by undesirable impairments of the hair structure. These impairments are expressed, among other things, in a deteriorated combability of the hair when wet or dry, an increased electrostatic charge, an increased brittleness, a reduced maximum tensile strength and elongation at break of the hair as well as a deteriorated external appearance of the hairstyle.

There has been no shortage of approaches to post-treating the hair with appropriate active ingredients in order to moderate or eliminate the extent of the circumstances mentioned. As a rule, cationic surfactants were used, often in combination with other auxiliaries. This procedure, which is well known from the prior art, is unsatisfactory in several respects. It is known that cationic surfactants are only suitable for treating non-greasy hair; However, their use is problematic in the case of rapidly regreasing hair, because they put additional strain on the hair and promote the natural regreasing of the hair.

In addition, the quaternary ammonium compounds commonly used as cationic surfactants are only insufficiently biodegradable, so that their use should be reduced as much as possible for ecological reasons.

In particular, however, it is unsatisfactory that the treatment with cationic surfactants generally has to take place in a separate step, usually a rinse, since these cationic surfactants are frequently not found in preparations based on anionic surfactants, as are usually used in shampoos. have it incorporated.

Description of the invention

There is therefore a constant need for hair cosmetic preparations which are distinguished by a reduction in the undesirable impairment of the hair without having the disadvantages of the agents of the prior art.

It has now surprisingly been found that preparations containing an amphopolymer and special esters of monovalent fatty acids meet these requirements in every respect.

The invention therefore relates to hair cosmetic preparations based on conventional constituents for cleaning and / or grooming hair, comprising an active ingredient combination of (A) an amphopolymer and (B) a fatty acid ester of formula R1-C00R2, wherein

- R ^{1 is} a saturated or unsaturated, linear or branched alkyl radical having 8 to 22 carbon atoms and

R is a saturated or unsaturated, linear or branched alkyl radical having 1 to 12 carbon atoms or a group (CHR ³ -C00) _n M, where R is a saturated or unsaturated, linear or branched alkyl radical having 1 to 4 C atoms, n is an integer from 1 to 5 and M is hydrogen, an alkali metal, an alkaline earth metal, aluminum or an alkyl or alkylolam onium group with 1 to 4 C atoms in each alkyl or alkylol group.

The preparations according to the invention bring about good wet combability of hair while at the same time increasing dry combability. This requires both a significant improvement in hair styling when wet, as well as an increase in hairstyle hold when dry. In addition, the preparations according to the invention improve the curl retention and the bounce of wavy hair. Last but not least, when applied to colored hair, pronounced color protection is achieved with good leveling. In addition, the color gloss is increased. The observed effects are surprisingly greater in the mixtures according to the invention than in preparations which contain only one of the components.

An amphopolymer (A) is understood to mean polymers which contain both free amino groups and free -C00H or SO3H groups in the molecule and are capable of forming internal salts, zwitterionic polymers which group quaternary ammonium groups in the molecule and -C00 "or -Sθ3" groups, and such polymers containing -C00H or SC ^ H groups and quaternary ammonium groups. An example of an amphopolymer that can be used according to the invention is the acrylic resin available under the name Amphomer ^, which is a copolymer of tert-butylaminoethyl methacrylate, N- (1,1,3,3-tetramethylbutyl) acrylate and two or more monomers represents from the group acrylic acid, methacrylic acid and their simple esters.

Further amphopolymers which can be used according to the invention are the compounds mentioned in British Laid-Open Application 2 104 091, European Laid-Open Application 47 714, European Laid-Open Application 217 274, European Laid-Open Application 283 817 and German Laid-Open Application 2817 369.

Ampho-polymers used with particular preference are those polymers which essentially consist of one another

(a) monomers with quaternary ammonium groups of the general formula (i),

R -CH = CR5-C0-X- (C _n H2n) -N ( ⁺ ) R ⁶ R ⁷ R ⁸ Ä ( ^" ) (i)

in which R ⁴ and R - independently of one another stand for hydrogen or a methyl group and R-, R7 and R ⁸ independently of one another for alkyl groups with 1 to 4 carbon atoms, X an NH group or an oxygen atom, n an integer from 2 to 5 and Ä (") is the anion of an organic or inorganic acid

and

(b) monomeric carboxylic acids of the general formula (ii),

R9-CH = CR10_C00H (ii) in which R9 and R ^ ~ are independently hydrogen or methyl groups.

These compounds can be used according to the invention both directly and in salt form, which is obtained by neutralizing the polymers, for example with an alkali metal hydroxide. With regard to the details of the production of these polymers, reference is expressly made to the content of German laid-open specification 3929973.

Polymers based on monomers of type (a) in which R-, Rδ and R? Are methyl groups, X is an NH group and A (") is a halide, methoxysulfate or ethoxysulfate ion; acrylic amidopropyl trimethyl ammonium chloride is a particularly preferred monomer (a). As monomer (b) for the mentioned polymers, acrylic acid is preferably used.

The active ingredients (A) are contained in an amount of 0.05 to 5% by weight, based on the entire preparation. Concentrations of 0.1 to 3% by weight are preferred.

In a preferred embodiment of the present invention, those compounds are used as fatty acid esters (B) in which the radical R ^{2 is} (CHR ³ -C00) _n M; R and M have the meaning given above, n stands for an integer from 1 to 3.

The active ingredients (B) are present in an amount of 0.1 to 10% by weight, based on the entire preparation. Concentrations of 0.5 to 5% by weight are preferred.

It has been shown that a particularly advantageous effect is achieved when the compounds (A) and (B) in a weight ratio of 1: 4 to 1:10 are present; Preparations in which the components (A) and

(B) approximately in a weight ratio of 1: 8 are particularly preferred.

It has also been found that good results in the sense of the teaching according to the invention are achieved if the mixtures according to the invention additionally contain a cationic surfactant (C). Preferred cationic surfactants

(C) are quaternary ammonium compounds.

Suitable quaternary ammonium compounds are, for example, alkyltrimethylammonium salts with 12-22 carbon atoms in the optionally substituted alkyl chain, such as e.g. Hexadecyltrimethylammoniumsalze and Ricinolsäuropropylamidotrimethylam oniumsalze, and Dialkyldimethylammoniumsalze with 2-22 C atoms in the optionally substituted alkyl chain such as e.g. 2-hy- droxyhexadecyl-2-hydroxyethyldimethylammoniumsalze, Dodecylethyldi ethylammoniumsalze, Stearylbenzyldimethyl-, Dodecylbenzyldimethyl- and other Alkylbenzyldimethylarnmoniumsalze, Distearyldi ethylammoniumsalze, fettsäureamidopropylethyldimethylammoniumsalze lanolin, cetyl-2-hydroxyethyldi- ethylammoniumsalze, Dikokosacyldimethylammoniumsalze, Dirübacyl-l, l-di- methylethyl -dimethylammonium salts, isopropyl diolate dimethylammonium salts, gluconamidopropyl-2-hydroxyethyl-dimethylamπ.oniumsalze, Mink- amidopropyl-2-hydroxyethyl-dimethylammoniumsalze.

Also suitable are polyoxyethylstearylammonium salts, penta (oxyethylene) octadecylammonium salts, bis-tallowacylaminoethyl-2-hydroxyethyl-methyl-a monium salts, di- (tallow carboxyethyl) -hydroxyethyl-methylammonium-methosulfate, cocospentaethoxy-methylethyl-3-ammonium acylamino-salts, linium salts, tallow alkylamidoethyl-methyl-2-tallowalkylimidazolinium salts, bis-oleylamidoethyl-2-oleylimidazolinium salts and alkylamidoethyl-methyl-alkylimidazolinium salts. Trialkylmethylammonium chloride, e.g. B. Tricetylmethylammonium chloride, also Glucquat 100 (CTFA-Na- e: lauryl-methyl gluceth-10-hydroxypropyl-dimonium-chloride). Compounds of the alkyl pyridiniu salt type, such as lauryl pyridinium salts, are also suitable. The alkyl and acyl groups contained in the compounds mentioned usually have about 12 to 22 carbon atoms. For example, halide ions, in particular chloride and bromide ions, lactate ions, methosulfate ions, ethosulfate ions, phosphate ions, hydrogen and dihydrogen phosphate ions, saccharinate ions and acetate ions can act as counterions in these salts.

The cationic surfactants (C) are preferably present in the preparations according to the invention in an amount of 0.05 to 5, in particular 0.1 to 3% by weight, based on the preparation as a whole.

In addition, it may be desirable to add certain cationic polymers (D) to the preparations according to the invention. Examples of suitable polymers (D) are:

- Quaternized cellulose derivatives, as are commercially available under the names Celquat ^R and Polymer JR ^R. The compounds Celquat H 100, Celquat L 200 and polymer JR ^R 400 are preferred quaternized cellulose derivatives.

- Copolymers of vinyl pyrrolidone with quaternized derivatives of dialkyl inoacrylate and methacrylate, such as, for example, vinyl pyrrolidone-dimethylaminomethacrylate copolymers quaternized with diethyl sulfate. Such compounds are commercially available under the names Gafquat ^R 734 and Gafquat ^R 755.

- Copolymers of vinyl pyrrolidone with vinyl imidazolium methochloride, such as those offered under the name Luviquat ^R. - Polymer Dimethyldiallylamπioniumsalze and their copolymers with esters and A iden of acrylic acid and methacrylic acid. The products commercially available under the names Merquat ^R 100 (poly (dimethyldiallylammonium chloride)) and Merquat ^R 550 (dimethyldiallylammonium chloride-acrylamide copolymer) are examples of such cationic polymers.

The cationic polymers (D) are preferably present in the preparations according to the invention in an amount of 0.05 to 5, in particular 0.1 to 3,% by weight, based on the preparation as a whole.

It is known to the person skilled in the art that the consistency of aqueous emulsions can be influenced in a targeted manner by adding so-called thickeners. It may therefore be desirable for the emulsions according to the invention to contain 0.1 to 10% by weight, preferably 0.5 to 5% by weight, of a thickener in order to set a viscosity suitable for the particular application. It is again preferred to use thickeners of natural origin. Such are e.g. Polysaccharides, in particular xanthan gum, guar gum, agar agar, alginates and tyloses, locust bean gum and pectins.

In addition, carboxymethyl cellulose, methyl hydroxypropyl cellulose and hydroxyethyl cellulose, higher molecular weight polyethylene glycol mono- and diesters of fatty acids, polyacrylates, polyvinyl alcohol and polyvinyl pyrrolidone are suitable as thickeners.

However, inorganic electrolyte salts can also be used as thickeners. All water-soluble alkali, onium and alkaline earth metal salts, for. B. the fluorides, chlorides, bromides, sulfates, phosphates and nitrates and hydrogen carbonates, insofar as they are soluble in water in an amount of at least 1 wt .-% at 20 ° C. The chlorides or sulfates of an alkali metal, ammonium or magne- siu s used; sodium chloride and magnesium chloride are particularly preferred. The amount of the electrolyte salt is preferably 0.1 to 10% by weight, in particular 0.2 to 5% by weight.

The skin-protecting properties of the agents according to the invention come into their own when they are formulated in such a way that they have a pH close to the neutral point of the skin. Agents with pH values in the range from 2.5 to 7.5, in particular from 3.5 to 5.8, are therefore preferred.

The preferred acidic setting of the agents according to the invention already has a positive effect on their durability. However, additional preservatives can be used. Suitable for this purpose are, for example, formic acid, propionic acid, salicylic acid, benzoic acid, sorbic acid, cinnamic acid and their esters and salts, furthermore menthol, thymol, eugenol and lemon grass extract as well as the substances listed in the annex to the Cosmetics Regulation. The preservatives are usually used in the hair treatment emulsions in amounts of 0.1 to 2% by weight. The use of benzoic acid as a preservative is particularly preferred.

The preparations according to the invention can be used both in those hair treatment processes in which the preparations are rinsed out of the hair after use, and in those hair treatment processes in which the preparation remains in the hair.

Preparations, after which the hair is usually rinsed, are, for example, shampoos, hair rinses, waving agents and colorants. Products that usually remain in the hair are, for example, hair setting agents, hair treatments and hair dryer preparations. Depending on the type of In addition to the mandatory components, all auxiliaries and additives customary for the respective application can be included.

In the case of shampoos, these are usually anionic, nonionic and zwitterionic surfactants, pearlescent agents, perfumes, agents for adjusting the pH, dyes, preservatives, optionally alkoxylated fatty acids and fatty alcohols and components for adjusting the viscosity in addition to the base of water.

Hair rinses, which are also usually based on water, generally contain quaternary ammonium compounds, lower alcohols, solubilizers, active ingredients such as. B. panthenol, nonionic polymers, viscosity adjusting agents and perfume oils.

In addition to water, hair setting agents usually contain lower alcohols, tensides, preferably nonionic, stabilizers, cationic and / or anionic polymers, agents for adjusting the pH and, in the case of formulations as foam hair setting agents, blowing agents.

Hair dyes usually contain direct dyes and / or precursors for oxidation dyes (coupler, developer components), surfactants, fatty alcohols, reducing agents, perfume oils and agents for adjusting the pH.

In addition to the reducing agent (thioglycolic acid, thiolic acid), waving agents generally contain components for adjusting the pH, surfactants, complexing agents, solubilizers, fatty alcohols and perfume oils. The corresponding fixing solutions contain oxidizing agents such as hydrogen peroxide and potassium bromate instead of the reducing agent. Particularly important of the auxiliary substances present in the consumer products mentioned are:

Surfactants / emulsifiers, e.g. anionic surfactants with carboxylate, sulfonate, sulfate or phosphate groups such as soaps, alkyl and aryl ether sulfates, fatty amines, quaternary ammonium and pyridinium compounds, nonionic emulsifiers such as ethylene oxide adducts with alcohols, carboxylic acids, partial glycerides and sorbitan esters, amphoteric and zwitterionic emulsifiers , Betaines or sulfobetaines and, for example Fatty acid esters and sorbitan fatty acid esters (cf. e.g. W. Umbach [ed.], "Cosmetics - Development, Manufacture and Use of Cosmetics", pp. 86-87, Stuttgart 1988).

Oil components, e.g. Substances such as paraffin oil, vegetable oils, fatty acid esters, squalane and 2-0ctyldodecanol; as fats and waxes, for example, walrus, beeswax, montan wax, paraffin and cetylstearyl alcohol.

Thickeners, e.g. Polysaccharides, in particular xanthan gum, guar gum, agar agar, alginates and tyloses, and also carboxymethyl cellulose and hydroxyethyl cellulose, as well as higher molecular weight polyethylene glycol mono- and diesters of fatty acids, polyacrylates, polyvinyl alcohol and polyvinyl pyrrolidone.

Superfatting agents, e.g. polyethoxylated lanolin derivatives, lecithin derivatives and fatty acid alkanols, the latter also serving as foam stabilizers.

Biogenic active ingredients such as plant extracts, protein breakdown products and vitamin complexes.

Humectants, for example glycerol, polyglycerols, sorbitol, 1,2-propanediol, 1,2,3-butanetriol, polyethylene glycols, mannitol, xylitol, pyrollidone carboxylic acid salts (PCA), amino acids, lactic acid. Antimicrobial substances as preservatives, such as benzoic acid, salicylic acid, sorbic acid, and their esters and salts, as well as the substances listed in the annex to the Cosmetics Regulation. Pearlescent agents such as ethylene glycol distearate or fatty acid monoglycol esters. Fragrances, for example natural fragrances, which are obtained from plants by distillation, extraction or pressing, and synthetically produced fragrances (see, for example, H.Aebi, E. Baumgartner, HPFiedler, G.Ohloff, "Cosmetics, Fragrances and Food Additives" , Stuttgart 1978).

Antioxidants, e.g. Tocopherols, lecithin, guaiacol, butyl cresol, 4-methyl-2,6-di-tert-butyl-phenol (BHT), 4-methoxy-2 (3) tert-butylphenol (BHA)

Dyes such as e.g. are compiled by the Dye Commission of the German Research Association for Cosmetics ("Colorants for Cosmetics" Notice 3, Wiesbaden 1968). The dyes are usually used in concentrations of 0.001 to 0.1% by weight, based on the mixture as a whole. pH regulators: If desired, further components of the agents according to the invention are substances which serve to adjust the pH of the agents.

The total amount of auxiliaries is 0-30% by weight, preferably 0-20% by weight.

To produce the mixtures according to the invention, components (A) and (B) or (A) to (C) or (A) to (D) are usually stirred together at 60 to 80 ° C. The mixtures are stirred and then cooled to normal temperature (20 to 40 ° C).

The preparations according to the invention are generally distinguished by a double function, since they have a cleaning and nourishing effect at the same time Have an effect. The main focus of the preparations based on the binary combination of active ingredients of (A) and (B) is the nourishing effect. Another object of the invention is therefore the use of the preparations according to the invention for the care of hair. As a result of the additional presence of cationic surfactants (C) and other auxiliaries with a surfactant character, which is possible according to the invention, the cleaning action of the preparations can be modified as desired.

In the treatment of hair, the preparations according to the invention are usually applied to the hair and, after an exposure time, rinsed off again with water. On the other hand, those preparations in which the nourishing character is in the foreground are applied to the hair and remain there.

The following examples serve to illustrate the invention and are not to be interpreted as restrictive.

2. Determination of dry combability

The combability test was carried out using the method according to J. Soc. Cosm. Chem. 1973 [24] 782 used as a basis.

The dry combing work was investigated on brown hair (Alkinco # 6634, strand length 12 cm, strand mass 1 g). It was slightly pre-damaged (bleached) hair, as can be expected from the average user. After the zero measurement, the strands were impregnated with 100 ml of the formulation to be tested. After a contact time of 5 minutes, the strands were rinsed out under running water (1 l / min, 38 ° C.) for 1 minute. The strands were then dried for 12 hours at 30 ° C. and a relative atmospheric humidity of 20% and then measured again and the result result compared to the zero measurement. The results of the dry combability tests are summarized in Table 1.

Table 1 Dry combability (-)

(1) The information in the upper block of the table relates to% by weight of active substance. The information in the lower block of the table relates to the experimentally determined value of dry combability TK in comparison to the zero measurement.

(2) The statistical certainty of the TC values was 99.99%.

The example B1 according to the invention has a significantly higher dry combability than VI and V2. Because TK is a measure of. for the hold of the hairstyle, an improvement in hairstyle hold has been proven for Bl. 3. Determination of wet combability

Wet combing was examined on brown hair (Alkinco # 6634, strand length 12 cm, strand mass 1 g). The hair was slightly damaged (bleached), as can be expected from the average user. After the zero measurement, the strands were impregnated with 100 ml of the formulation to be tested. After an exposure time of 5 minutes, the strands were rinsed out under running water (1 l / min, 38 ° C.) for 1 minute. The strands were measured again and the result compared with the zero measurement. The results of the wet combability tests are summarized in Table 2.

Table 2 wet combability)

(1) The information in the upper block of the table relates to% by weight of active substance. The information in the lower block of the table relates to the experimentally determined value of the wet combability NK in comparison to the zero measurement. (2) The statistical certainty of the TC values was 99.99%.

Example B1 according to the invention has a significantly lower value for wet combability than VI and V2. Since lower values of NK mean better combability of wet hair, an improvement in wet combability has been shown for B1.

4. Determination of curl retention

A 15 cm long strand of hair (Alkinco 6634; strand weight: 2 g) was treated with 0.5 g of the substance, left to act for 2 minutes, rinsed and wound on a glass tube with an outer diameter of 2.0 cm, fixed and dried. A measure of the stability of the curl obtained after pulling out the glass rod is the curl retention value. The curl retention value (CR value) is defined as [(ll _x ) / (ll ₀ )] * 100%, where 1 is the length of the strand of hair (15 cm), 1 _{0 is} the length of the lock of hair immediately after drying and l _{x is} the length of the hair curl after 8 hours storage hanging in a drying cabinet at constant conditions (25 ° C, 60% relative humidity) is. The results of the measurements are summarized in Table 3.

Table 3 curl retention)

(1) The information in the upper block of the table relates to% by weight of active substance. The information in the lower block of the table relates to the experimentally determined CR value.

The example B1 according to the invention has a higher CR value than VI and V2. Since higher CR values indicate an improved curl retention capacity, an improvement in the curl retention capacity is shown for B1.

5. Determination of bounce

An apparatus is used for the objective evaluation of the influence of hair treatment agents on the bounce of hair, in which individual locks of hair are attached to a force measuring device. The curls are treated preparatively on winders with diameters that give exactly one turn. The winding lies in the plane that is perpendicular to the horizontal. Then the curl with a special bracket, which is located within the curl, moves downwards; this movement continues until the end of the curl slides past the bracket and swings upwards. The damped vibration of the curl is a measure of the elastic vibration of the hairstyle. The stretching work, the initial amplitude, the oscillation frequency and the damping constant of the damped oscillation are used to evaluate the means with which the curls were treated.

The results of the measurements are summarized in Table 4. A summary of the measured values for MP1, MP5 and MP6 shows that the example B1 according to the invention has a significantly improved bounce compared to V3 and V4.

The desired state of resilience of the hair, achieved by the compositions according to the invention, can be clearly understood to lie between the extremes of a fully elastic, undamped oscillation and a "shock-absorber-like" strongly damped oscillation. For the measured value MP1, this means, for example, that the frequency values of the comparisons are close to the vibration braked like a shock absorber, while example B1 shows an increased frequency. The example B1 shows at the same time - as can be seen from the values MP5 and MP6 - a higher damping.

Table 4 Bounce (!)

(1) The information in the upper block of the table relates to% by weight of active substance. The data MP 1 to MP 6 in the lower block of the table relate to the experimentally determined measurement parameters (the data in each case represent the differences between treated and untreated strands of hair). They were measured uniformly at a relative air humidity of 60%. The meanings are: MP 1 = frequency in s-1; MP 2 = maximum stretching work in j; MP 3 = 0 amplitude of the maxima in mN; MP 4 = O amplitude of the minima in mN; MP 5 = attenuation of the maxima in s "l; MP 6 = attenuation of the minima in s'l. 6. Examples of use

Typical examples of recipes based on the mixtures according to the invention are given in the examples in Table 5. All percentages are to be understood as% by weight of active substance. The difference to 100% is water.
