Abstract

Coated pigments and diluent pigments for use in cosmetic products, in which the pigments and diluent pigments are coated with a mixture comprising at least the N-acyl derivatives of the 14 amino acids glycine, L-alanine, L-valine, L-leucine, L-isoleucine, L-phenylalanine, L-proline, L-threonine, L-serine, L-arginine, L-histidine, L-lysine, L-aspartic acid and N-glutamic acid, the N-acyl derivatives optionally being in the form of salts.

Description

The subject of the present invention is pigments and diluting pigments.

  new coated materials, in particular a new coated material in a finely pulverized state (powdery), that is to say new coated pigments and diluents which can be used for cosmetic products, and new cosmetic products containing

  coated pigments and diluents.

  It relates more particularly to the diluting pigments and pigments, coated with a mixture comprising at least 14 acylated amino acids or their salts, the amino acids being obtainable from or being obtained by total hydrolysis of any of the animal proteins , such as silk and mother-of-pearl, and vegetable proteins, such as wheat and soy proteins, as well as cosmetic products containing these pigments and diluent pigments. Pigments and thinners pigments, coated with a mixture

  comprising at least 14 acylated amino acids, said amino-

  acids which may be present in the form of salts in one or more of the 14 amino acids, are extremely soft to the touch and have greater cohesion with the skin and the hair (biocompatibility), which means that cosmetic products comprising pigments and pigments thinners are considered to be highly promising as a

  cosmetic products having these advantageous properties.

  Pigments and diluent pigments, added to cosmetic products, in particular inorganic pigments, have better spreadability (spreading capacity), are hard and heavy (coarse), that is to say free of elasticity, and generate a feeling of resistance, thereby causing physical irritation to the skin. In addition, since these pigments are inorganic, they have a poor affinity for the skin. In this regard, a good affinity for the skin means a light sensation to the touch of the skin and a pleasant cutaneous sensation. To overcome these drawbacks, a certain number of types of coated pigments and diluents have been proposed, that is to say surface-treated pigments and diluents. For example, a number of different methods have hitherto been known, such as a surface coating method with oily esters, a metallic soap, lecithin, a silicone oil, a perfluoroalkyl oil, or a method coating with a single acylated amino acid or an acylated form of a polypeptide, which is an amino acid polymer;

  see Japanese patent publication Kokai JP-A-6 173 775.

  During the preparation of this invention

  tion, the following problems were also noted by

the present inventors.

  In connection with the aforementioned references concerning

  In this area, the known techniques mentioned above

  have a number of drawbacks.

  Pigments and thinners pigments, coated with oily esters, a metallic soap, lecithin, a silicone oil or a perfluoroalkyl oil, although having a soft tactile sensation and generating reduced physical stimuli in the skin, have a poor compatibility with the human body, which makes

  that they have a bad affinity for the skin.

  There has been described the coating of pigments and diluent pigments with amino acids or polypeptides to improve affinity with the skin, as described in Japanese patent publication Kokoku JP-B-1202, and patent publications Japanese Kokai JP-A-61-73 775,

  JP-A-61-10 503, JPA-61-7 207, JP-A-61-69 709, JP-A-5-186 706,

  JP-A-3 200 879, JP-A-9-328 413 and JP-A-10-226 626. Although these publications indicate that the pigments and diluents pigments coated have a soft tactile sensation and a great affinity for the skin , it is not possible to consider that the advantageous effect of pigments and pigments

coated thinners is optimal.

  Pigments and diluent pigments, coated with an N-acylated amino acid, as described in Japanese patent publication Kokoku JP-B1-50 202, by

  example with N-acyl-L-glutamic acid, N-methyl-

  N-methylglycine or N-acyl-N-methyl-3-alanine, although having a mild tactile sensation, do not exhibit optimal affinity for the skin. Pigments and diluent pigments, coated with an N-acylated peptide, are not sufficiently smooth and also generate harmful physical stimuli, due to the hard and heavy (coarse) sensation generated by the polypeptides (refer to patent publication

Japanese Kokai JP-A-61-73 775).

  Pigments and thinners pigments, coated with a basic N-mono-amino acid with long chain, although having a soft tactile sensation, do not have an optimal affinity for the skin due to the presence of basic amino acids (see Japanese patent publications Kokai JP-A-61-10 503, JPA-61-7 207, JP-A-61-69 709

and JP-A-5-186 706).

  In a similar way about the publica-

  Japanese patent Kokoku JP-B-1-50 202, pigments and diluent pigments coated with N-acylated aspartic acid,

  although having a soft tactile sensation, does not present

  not try an optimal affinity for the skin (see the publica-

  Japanese patent Kokai JP-A-3-200 879).

  Consequently, as in the case of pigments and diluting pigments, coated with the N-acylated peptide, the

  pigments and diluents pigments mentioned above do not equally

  not a soft sensation beneficial to the touch or an advantageous affinity for the skin (with regard to the pigments and diluent pigments coated with the N-acylated silk peptide, described in the Japanese patent publication Kokai JP-A-9- 328,413, see Japanese patent publication

Kokai JP-A-61-73 775).

  Pigments and diluent pigments, coated with sericin, which contains a large amount of serine, which consists of one of the hydroxyamino acids retained as

  that amino acids can be used in place of an AHA (a-hydroxy-

  acid), exhibit improved affinity with the skin (see Japanese patent publication Kokai JP-A-10-226 626). However, a soft tactile sensation cannot be obtained5 with such a substance. For the above reason, it has been desired for a long time to develop pigments and coated diluting pigments having a pleasant sensation during application and a superior affinity for the skin or the hair. An object of the present invention is to provide pigments and diluting pigments having a soft tactile sensation when used in cosmetic products and excellent cohesion with the skin and the hair, that is to say having a superior affinity. 15 higher for skin or hair (biocompatibility). Another objective of the present invention consists in proposing

  cosmetic products with the advantageous properties

  mentioned above due to the presence in these products

  cosmetic pigments and thinners pigments mentioned above

above.

  The present inventors have carried out research

  in depth to solve the above problems and have

  found that the pigments and thinners coated pigments include

  containing pigments and diluting pigments, in the form of a material in the finely pulverized state, coated with a mixture comprising at least the N-acylated forms of 14 amino acids consisting of glycine, L-alanine, L-valine, L -leucine, L-isoleucine, L-phenylalanine, L-proline, L- threonine,

  L-serine, L-arginine, L-histidine, L-lysine, L-aspar- acid

  tick and L-glutamic acid, preferably coated with a mixture comprising at least the N-acylated forms of the 14 amino acids, obtainable or being obtained by

  acylation of amino acids comprising at least the 14 amino-

  acids, represented by the following general formula:

R2CHCOOM

J

HNCOR1 (1)

  and obtainable by total hydrolysis of at least one type of protein preferably derived from animal proteins, such as silk and mother-of-pearl, and vegetable proteins, such as wheat and soy proteins, formula in which R1 represents an alkyl group having 8 to 22 carbon atoms which may contain a carbon-carbon double bond and / or a carbon-carbon triple bond in the molecule, such as an alkenyl group, saturated or unsaturated, or a hydrocarbon group having a structure alicyclic from 8 to 22 carbon atoms, saturated or unsaturated

R2CHCOO

I HN

  which consists of any residue from one of the 14 amino-

  acids, more precisely any of the glycine, alanine, valine, leucine, isoleucine, phenylalanine, proline, threonine, serine, arginine, histidine, lysine, aspartic acid and glutamic acid residues, M is chosen from H, Na, K, a polyvalent metal such as Ba, Zn, Ca, Mg, Fe, Zr, Co, Al and Ti, the ammonium ion and an alkanolamine onium

  organic, such as monoethanolamine, diethanol-

  amine, triethanolamine, 2-amino-2-methyl-propanol, 2-amino-2methyl-1,3-propanediol and triisopropanolamine, have an extremely soft tactile sensation and a superior affinity for the skin and hair and, in addition, are particularly suitable for addition to cosmetic products. In the aforementioned cases, such an N-acylated form may be in the form of a salt and, consequently, such

  N-acylated form consists of the free form and / or the salt.

  This discovery made it possible to complete the

present invention.

  More specifically, the present invention contains the following aspects: 1. the coated diluents pigments and pigments usable in cosmetic products comprising diluents pigments and pigments, said diluents pigments and pigments being coated with a mixture comprising at least the N-acylated forms of 14 amino acids consisting of glycine, L-alanine, L-valine, L-leucine, L-isoleucine,

  L-phenylalanine, L-proline, L-threonine, L-serine, L-argi-

  nine, L-histidine, L-lysine, L-aspartic acid and L-glutamic acid, the N-acyl-amino acid can be in salt form, which means that the amino acid can be in free form and / or in the form of salt; the 14 amino acids, in the present invention, are L isomeric forms occurring in nature or available from natural substances. However, glycine does not have asymmetric carbon atoms and, therefore, does not have such an isomeric form, consisting of an L or D form. In most cases, the amino acids have isomers. In such amino acids, the amino acids can be used in the form of a mixture of isomers or of a compound formed of these isomers insofar as the amino acids contain the isomers existing in nature

  or available from natural substances, i.e.

  say in the form L. If, for example, there are forms

  D and L, the form L exists in nature. In such amino-

  acids, amino acids of forms D, L can be used in the present invention insofar as the amino acids contain the naturally occurring form L. It is also possible that the mixture containing the N-acylated form used in the present invention contains other N-acylated forms of any L-amino acids other than those used in the present invention, such as L- tyrosine, L-methionine, L-cystine and L-cysteine, and acylated forms of any amino acid isomers other than those mentioned above (glycine and the 13 L-amino acids) and substances other than amino acids and their derivatives, provided that the mixture contains the 14 forms

  Above-mentioned N-acylates used in the present invention.

  In basic amino acids, having several amino groups, including imino groups, such as lysine, it is sufficient that the N-acylated form is a derivative of which at least one N position is acylated. The N-acylated form of amino acids, used in the present invention, may be a free form or be in the form of a salt. In the latter case, the forms or bases for the salts of the amino acid derivative in the salt forms are independent of each other and may be in whole or in part identical forms or bases or

different for these salts.

  It is sufficient that the amino acid serving as starting material is in the natural form (L form with the exception of glycine) and it can be in the form of a mixture if it contains this isomer. There are no limitations with respect to the routes of production. Accordingly, the amino acids produced by various production methods, such as extraction, synthesis, a method of production by microorganisms and a method of hydrolysis of proteins or peptides, can be used. It should be noted that these amino acids other than glycine are in the L form. The process for coating pigments and pigments

  thinners (finely sprayed substances) may not be

  which of the known coating processes used classi-

  only for the modification of pigments and diluting pigments which have been used previously in the field of

cosmetic products.

  2. The pigments and coated diluent pigments corresponding to the above definition in which at least part (all or part) of the 14 amino acids consists of at least one of the amino acids which can be obtained from a total hydrolyzate (hydrolysis product) of a protein; 3. coated pigments and diluting pigments meeting the above definition in which the protein can be obtained from an animal protein, or consists of at least one of the animal proteins, such as silk, mother-of-pearl, collagen, keratin, etc., and vegetable proteins, such as wheat, soy protein, etc., containing the 14 amino acids as the main constituent amino acids; 4. coated pigments and diluting pigments corresponding to the above definition in which the mixture comprising at least the N-acylated forms of the 14 amino acids comprises 14 acylated amino acids, which can be obtained by

  acylation of amino acids containing at least 14 amino-

  acids, represented by the following general formula, the N-acylated form possibly being in the form of a salt:

R2CHCOOM

HNCORN (1)

  and obtainable or being obtained by total hydrolysis of at least one type of protein, formula in which R1 represents an alkyl group or an alicyclic hydrocarbon group each having 8 to 22 carbon atoms, saturated or unsaturated

R2CHCOO

  I HN represents an amino acid residue, more precisely any of the glycine, alanine, valine, leucine, isoleucine, phenylalanine, proline, threonine, serine, arginine, histidine, lysine, aspartic acid and

  glutamic acid, M is chosen from H (a hydro-

  gene), a metal atom, the ammonium ion and an onium of an organic alkanolamine; 5. the pigments and coated diluent pigments corresponding to the above definition in which the metal atom consists of any one of Na, K, Ba, Zn, Ca, Mg, Fe, Zr, Co, A1 and Ti and the organic alkanolamine is any of the compounds consisting of monoethanolamine, diethanolamine, triethanolamine, 2-amino2-methylpropanol, 2-amino-2-methyl-l, 3-propanediol and triisopropanolamine; 6. coated pigments and diluting pigments corresponding to the above definition in which at least part of the 14 amino acids consists of one or more amino acids which can be obtained or are obtained by total hydrolysis of a protein derived from at least one of the substances consisting of silk and mother-of-pearl; 7. the coated pigments and diluting pigments corresponding to the above definition, in which the diluting pigments and pigments are coated with a mixture containing the N-acylated forms of amino acids obtained by total hydrolysis of at least one of the proteins chosen from silk, mother-of-pearl, collagen, keratin, wheat protein, soy protein, etc. According to the present invention, any pigments and diluent pigments, coated with a mixture containing at least the N-acylated forms of the aforementioned 14 amino acids, can be used as pigments and coated diluent pigments of the present invention. It is desirable

  to impart a soft feeling of incorporating one or more

  other natural amino acids (form L), in addition to the 14 amino acids mentioned above, to the N-acylated amino acids used for the present invention. In addition, from a production point of view, it is preferred to coat the pigments and diluent pigments with a mixture obtained by total hydrolysis of a protein such as silk, followed by Nacylation. Examples of additional amino acids which can be advantageously incorporated include L-tyrosine, L-methionine, L-cystine, L-cysteine, etc .; and 8. cosmetic products comprising

  coated pigments and diluents meeting the definition

  tion according to any one of the aforementioned paragraphs 1 to 7.

  In the process of mixing these pigments and diluent pigments in the present invention to prepare

  cosmetics, it is possible to use any

  wear what suitable processes previously known for

  mix or combine the known pulverized materials or other known coated pulverized materials used for cosmetic products during the preparation of these cosmetics.

  Other features and advantages stand out

  from the detailed description which follows, made in

  look at the attached drawing in which: FIG. 1 represents the results of the test for the softness of the pigments and diluent pigments in the present invention. Coated pigments and thinners

  intended to be mixed with conforming cosmetic products

  ment to the present invention consist at least in part of

  pigments and diluting pigments mixed with cosmetic products

  ticks that are (at least in part) coated on the surface

  by treatment with a mixture comprising 14 amino derivatives

  N-acyl acids which may include one or more forms

  free and / or one or more salts. Although the 14 amino-

  aforementioned acids are sufficient as amino acids for N-acylation, it is desirable to incorporate in addition to the mixture of natural amino acids (L forms) to improve

more sweetness.

  As amino acids before acylation according to the present invention, natural amino acids are advantageous. As starting materials, the amino acids which can be obtained or obtained by total hydrolysis of one or

  several proteins containing mainly the 14 amino-

  aforementioned acids or a greater number of amino acids, and in particular the aforementioned 14 amino acids, such as

  animal proteins, including silk, mother-of-pearl, colla-

  gene and keratin, and plant proteins, such as

  wheat and soy proteins are used advantageously-

  is lying. Most simply, the mixture of amino acids resulting from total hydrolysis is N-acylated and applied to the pigments and

thinners pigments for coating.

  With regard to silk, it is possible to use cocoons of silkworms, raw silk, cocoon residues, residues of raw silk thread, silk thread, residues of silk fabric, etc. . As mother-of-pearl, it is possible to use various mollusc shells, such as mussels, freshwater mussels, hard shell mussels, mytilidae, bivalves, etc. As collagen, it is possible to use cow or beef skin tissue, soft bone tissue and pigskin, collagen extracted from the connective tissue of fish, such as cod, flatfish, halibut, sardines, salmon, trout, mackerel, tuna and grouper, Daucus carota (vegetable), etc. As keratin, it is possible to use wool, animal fur, human hair, leather, nails, and keratin of plant origin, for example soy keratin, wheat, barley ,

corn, sesame and millet.

  With regard to the tactile sensation, the pigments and diluting pigments coated with the amino acids of mother-of-pearl or their salts or acylated silk consisting mainly of acylated forms of total hydrolysates (hydrolysis products) of fibroin silk and

  conchyoline, containing a considerable amount of alkyl-

  amino acids such as glycine and alanine are

geux.

  For economic reasons, pigments and diluent pigments coated with acylated amino acids derived from silk, which can be in the form of salts, mainly consisting of total hydrolysates (products

  hydrolysis) acylates of silk fibroin are preferred.

  The acylated amino acids used in the present invention can be prepared using known methods, such as those described in Japanese patent publication Kokai JP-A-6-256 274 or patent publication

Japanese Kohyou JP-A-7-502 010.

  For example, hydrolysis of cocoon silk threads with strong acids, such as hydrochloric acid or sulfuric acid, gives peptides, such as fibroin or sericin. By further hydrolysis, these peptides are transformed into amino acids which can then be acylated with long chain fatty acids having 9 to 23 carbon atoms and sometimes transformed into salts, when necessary. The amino acids used in the present invention are in the form of a mixture of distinct unpolymerized amino acids. In the above general formula (1), R1 represents alkyl groups or alicyclic hydrocarbon residues having 8 to 22 carbon atoms of long chain fatty acid residues, which may sometimes contain any unsaturated carbon-carbon bonds. The constituent fatty acids for N-acylation in the present invention may include capric acid, lauric acid, myristic acid, isomyristic acid palmitic acid, isopalmitic acid, stearic acid, l isostearic acid, arachic acid, undecylenic acid, oleic acid, myristic acid, elaidic acid, linoleic acid, linolenic acid, arachidonic acid, fatty acid palm oil, acid

  beef tallow fat and resinic acid (abietic acid).

  The acylamino acids used in the present invention are preferably in the form of polyvalent salts

  since the acids are then hydrophobic.

  The acylamino acids can be acylamino-

  commercially acquired acids, such as "C8 SILK HYDRO", "C12 SILK Na" and "IC16 SILK ACID", which are marketed by PHYTOCOS, France, and "amino-form W" (Croda, Japan)

"Crosilk A / S" (Croda, United Kingdom).

  Examples of amino acid compositions

  of animal origin such as silk and mother-of-pearl, and of

  vegetable gine such as those derived from wheat and soybeans, constituting the side chain R2 in the general formula (1) above, are presented in Table 1. Since the 14 amino acids are present in these compositions, the mixture of the N forms -acylated obtained from the amino acid compositions indicated in the table is included in the

  mixture containing at least the N-acylated forms of the 14 amino-

  acids used in the present invention.

Pigments and thinners for cosmetic products which will

  developed in the future may also be used.

  With regard to the diluting pigments and pigments, it is possible to cite as fillers, for example, mica, sericite, talc, kaolin, synthetic mica, calcium carbonate, magnesium carbonate, silicate of magnesium, aluminum silicate, calcium phosphate, silicic anhydride, alumina, magnesium oxide, aluminum hydroxide, barium sulfate, magnesium aluminate silicate, metasilicate magnesium aluminate and boron nitride. In addition, it is possible to cite as white pigments titanium dioxide, zinc oxide and cerium oxide, it is possible to cite as colored inorganic pigments red iron oxide, yellow iron oxide , black iron oxide, chromium oxide, chromium hydroxide, Berlin blue, blue

  overseas, etc., as pigments and diluents used.

  It is also possible to cite pearlescent pigments consisting of bismuth oxychloride, mica or titanium (mica

  coated with titanium) and flakes of fish scales.

  It is also possible to cite organic resin powders consisting of nylon powders, polyethylene powders, polyurethane powders, polystyrene powders, methyl methacrylate polymer powders, silicone powders, Teflon, cellulose powders, polyvinylpyrrolidone powders, etc. As other powders for pigments and diluent pigments, mention may be made of a dye derived from tar, as organic pigment, aluminum powders, stainless steel powders, etc. The pigments and diluent pigments used can be in the form of mixtures with multiple constituents, complex composite products, fixed products or similar products known in the forms and processes usually used for cosmetic products. For example, these pigments and diluent pigments can be formulated or doped, as required. For example,

  pigments and diluting pigments made up of inorganic pigments

  colored nicks, such as red iron oxide, coated with silicic anhydride, powders consisting of nylon coated with white pigments, powders consisting of a filler coated with a white pigment in ultrafine particles, etc., are cited. The type or quantity of pigments and diluting pigments used for cosmetic products are chosen according to the objective sought, the configuration of the cosmetic products and similar parameters. For example, one or more of the aforementioned pigments and diluting pigments can be used. Pigments and thinners that will be developed in the future may also

  be used. The type, quantity or process of use

  tion are chosen in association with the methods of use

  tion known pigments and thinners pigments that can be used in cosmetic products or processes that

will be developed in the future.

  The amount of acylated amino acids applied as a coating to the pigments and diluent pigments is in the range of about 0.1 to 30% by weight and preferably about 1.0 to 10% by weight. weight based on the diluting pigments and pigments, as a function of the particle diameter, the specific surface or the surface properties of the diluting pigments and pigments. If the amount of acylated amino acids is less than 0.1% by weight, an optimal tactile sensation cannot be obtained while, if it exceeds 30% by weight, not only does it result in economic loss but, in addition, soft tactile sensation or affinity for skin and hair does not

can be improved.

  These pigments and diluting pigments can be

  coated by any known process with amino-

  acyl acids. For example, the water-soluble salts of amino-

  acyl acids are dissolved in water and the pigments and diluent pigments are added to this solution and are finely dispersed there. During the stirring of the liquid dispersion, an aqueous solution of polyvalent metal ions, for example salts of Mg, Ca, Co, Zn, Ba, Zr, Al, Ti, etc., is applied there dropwise to make the coating. The coated product is filtered, washed and then dried. The water-insoluble acylated amino acid salts are dissolved in suitable solvents such as ethyl acetate, mixed with the diluting pigments and pigments and dried to obtain the coated diluting pigments and pigments. However, the present invention is not limited to this method of

coating.

  The amount of the coated pigments and diluents pigments incorporated into the cosmetic products, optionally selected depending on the properties of the cosmetic products, is in the range of about 0.01 to 100% by weight based on the total composition. One or more different types of pigments and thinners pigments

  can be used sometimes, as needed.

  In the present invention, it suffices to use the coated diluting pigments and pigments, which consist of a coated pulverulent material, obtained in accordance with the present invention, as at least part of the diluting pigments and pigments used in cosmetic products. However, more of the coated pigments and thinners are desirable in the present invention. To achieve an optimal effect, an amount of at least 10% and preferably not less than 50% of the pigments and diluting pigments used in cosmetic products thus consists of pigments and pigments

  diluents coated in accordance with the present invention.

  Cosmetic products to which pigments and thinners pigments coated with the mixture are added

  of acylated amino acids can consist of cosmetic

  makeup ticks, such as powder foundation, liquid foundation, oily foundation, stick foundation, compressed powder, facial powders, lipstick, lip gloss , lip pencil, eye shadow, eyebrow pencil, brown pencil, eyeliner, mascara, water nail polish, oily nail polish, emulsion nail polish, a protective layer and a base layer for nail polish, cosmetic products for the skin such as an emollient cream, a cold cream, a white cream, a lotion, aqueous cosmetic products, care liquids, a lotion carmine, a liquid cleansing cream, a cleansing cream, cleansing powders, a cleansing foam, a makeup remover and a body lotion, hair cosmetic products such as a hair gloss, a hair cream, a shampoo, a hair rinse, hair coloring products and volumizers, and other products such as sunscreen and tan creams and lotions, soaps, bath products and perfumes. Cosmetic products comprising the pigments and diluting pigments coated with the mixture comprising at least 14 acylated amino acids, in which the amino acids may be in the form of salts, may be added with pigment dispersing agents, oily ingredients , of

  surfactants, UV absorbing agents, antisep-

  ticks, antioxidants, film-forming agents, hydrating agents, thickeners, dyes, pigments or

  perfumes, conventionally used in cosmetics-

  ticks, as described above, and in a quantity

  not altering the effects obtained in the present invention.

  The reasons why the pigments and diluent pigments coated with the mixture of acylated amino acids of the present invention offer an extremely soft tactile sensation and have a higher affinity for the skin or the hair (biocompatibility) can be summarized as follows:

  first of all, amino acids are constituents

  basic kills of proteins from living organisms. A

  protein is a compound with a diverse steric structure

  It consists of thousands to tens of thousands of polymers having dimensions greater than those of polypeptides which are polymers of hundreds of 5-amino acids. These proteins and polypeptides are made up of approximately 20 different amino acids and exhibit extremely high safety and considerable adaptability to living organisms, and therefore

  suitable as constituents of cosmetic products.

  However, since proteins have an immunological activity vis-à-vis living organisms and are harder due to their steric structure, amino acids and polypeptides are used preferentially to the

  place of these proteins in cosmetic products.

  It is considered that the higher the degree of polymer

  The higher the amino acid content, the greater the film-forming (film-forming) properties. However, higher polymerization means lower affinity for, or absorption capacity by, the skin and

  hair. In other words, the isolated amino acids,

  ie the amino acid monomers, have a maximum affinity for the skin and the hair. As a result, it is

  amino acids are considered to have reparative effects

  skin and restorative effects on the hair

damaged.

  Second, the advantage of acylation of

  amino acids with alkyl groups or hydrocarbon groups

  ales with an alicyclic structure sometimes containing one or more carbon-carbon unsaturation double bonds, such as alkenyl groups, saturated or unsaturated, having 8 to 22 carbon atoms, is the obtaining of a soft and slippery tactile sensation characteristic of higher fatty acids. The amino acid carries diverse functional groups, such as -COO-, -NH3 * or -OH groups, and is adsorbed with water molecules, so that it exhibits water retention properties . In general, it is believed that an oleophilic amino acid has a higher affinity for the skin and hair than a hydrophilic amino acid. For this reason, the amino acid is acylated with superior fatty acids and is thus made oleophilic to increase affinity for the skin and hair. This means that, since the N-acylated amino acid is able to supply water and oil simultaneously, the skin and

  hair needing these two constituents, this pro-

  priety is responsible for its superior affinity for

the human organism.

  It has been found that the higher the degree of polymerization

  The higher the amino acid content, the more the sticky feeling and the hardness specific to the peptides are manifested, which leads to a loss of the satisfactory tactile sensation caused by acylation. This means that the optimal tactile sensation can be obtained by acylating the amino acid instead of the polypeptide. If the number of carbon atoms in the acyl group is less than 8, astringent skin irritation occurs with a reduced tactile sensation while, if the number of carbon atoms is greater than 22, there is an heavy (coarse) tactile sensation and loss of softness, which is therefore not

not preferable.

  Third, there are approximately 20 amino acids in the composition of the human body. These amino acids are classified into alkylamino acids, such as glycine and alanine, oxyamino acids, such as serine, basic amino acids, such as lysine and arginine, amino acid acids such as l and glutamic acid

  aspartic, and aromatic amino acids such as tyrosine.

  A mixture of the amino acids obtained by total hydrolysis of at least one of the proteins of animal origin such as silk and mother-of-pearl, and of vegetable origin, such as wheat and soy proteins, contains 14 or more 14 amino acids, as described above, these amino acids entering

  the composition of living organisms. These various amino-

  acids play complex roles in establishing the affinity of the amino acid by the living organism, so that a satisfactory affinity cannot be obtained with

  a single amino acid or a mixture of a few amino acids.

  The mixture of acylated amino acids made up of various amino acids is considered to have optimal performance with regard to the soft tactile sensation and

  affinity for skin and hair (bioadaptability).

  The 14 or more of 14 amino acids used in the present invention can be produced by any

  which of the synthesis, fermentation or extraction processes

  tion. Similar effects can be achieved by coating

  pigments and thinners pigments with a mixture of amino-

  distinct acyl acids. These processes, which should be included in the present invention, are very expensive with the current production technique and are therefore not economically advantageous at present, but can be expected to do the object

improvements in the future.

  The various amino acids, obtained by total hydrolysis of an animal protein, such as silk and mother-of-pearl, or a vegetable protein, such as wheat and soy protein, usually have amino acid compositions different due to differences in the starting materials. The experiments carried out by the

  Applicant indicate that, the higher the proportion of 3 amino-

  acids, consisting of glycine and alanine as alkyl-

  amino acids and serine as the oxyamino acid in the total amino acid composition, the greater the affinity

  for skin and hair is strong.

  In cosmetic products, the tactile sensation is a very important factor to assess. The ability to spread evenly when applied to the skin without abrasion and a feeling of roughness is crucial. The feeling of abrasion and roughness is responsible for the irritation

  physical and causes roughness of the skin and inflammation

  cutaneous tion. Affinity is classified in the criteria of finish of cosmetic products allowing to obtain a lightness of load on the skin, a soft feeling and application and a great harmlessness. This means that, in order to obtain diluting pigments and pigments with an extremely soft tactile sensation and a very high affinity for the skin and hair (biocompatibility), it is crucial to coat the diluting pigments and pigments with a mixture of acylated amino acids. , in which the amino acids can be in the form of salts, such as polyvalent metal salts, this mixture being obtained by acylating at least 14 amino acids themselves obtained by total hydrolysis of an animal protein such as silk and mother-of-pearl, or a vegetable protein such as protein

wheat and soy.

  Pigment and diluent pigment smoothness test The diluent pigments and pigments were applied to a sheet of collagen paper 8 cm by cm produced by IDEMITSU KAGAKU under the trade name "1SUPPLALE", in an amount of 1 mg / cm2, and the assembly was placed on a test apparatus for measuring the alternative coefficient of friction produced by KATOTEC. A sheet of uncoated collagen paper was placed and subjected to a load of 50 g / cm2. The resulting assembly was subjected to an alternating movement five times in order to graphically represent the variations in the coefficient of friction (MIU). The smoothness determination tests were performed on sericite representing the

  most significant difference in smooth feel.

  FIG. 1 represents the results of the test for determining the smooth sensation of the pigments and diluent pigments. As can be seen in FIG. 1, the pigments and diluent pigments coated in Examples 1 to 7 of the present invention have a low coefficient of

  friction and give an excellent smooth feeling (sensa-

  smooth touch). In addition, the pigments and diluent pigments of the present invention are superior to the

  uncoated sericite, i.e. untreated sericite.

  The pigments and coated diluent pigments of the present invention were transformed into facial powders having the following simple composition, which were then evaluated by a set consisting of thirty subjects in order to determine the affinity for the skin according to the following criteria. The affinity for the skin was controlled by means of four criteria consisting of spreadability, smoothness on application, wet feeling and

sensation after application.

  The smooth tactile sensation and the affinity for the skin of the pigments and diluting pigments coated with the present

  invention, in dosage form, have been controlled.

  The hair treatment agent of Comparative Example 19 was powdery and had poor affinity, while that of Example 18 was able to smooth the

  hair and had an affinity for hair.

  The following test was carried out to control the effect in cosmetic products of pigments and coated diluent pigments of the present invention with regard to the smooth tactile sensation and the affinity for

skin and hair.

  (Smooth tactile sensation test of a double foundation, a liquid foundation and a moisturizer) The pigments and diluting pigments were applied to a sheet of collagen paper 8 cm by 5 cm produced by IDEMITSU KAGAKU under the trade name "SUPPLALE", in an amount of 1 mg / cm2, and the sheet was placed on a test apparatus for measuring the alternative coefficient of friction produced by KATO-TEC. A sheet of uncoated collagen paper was installed and subjected to a load of 50 g / cm2. The resulting assembly was subjected to five alternative movements to obtain the average value of the five coefficient values (MIU). This operation was

  repeated three times to obtain an average value.

  (Hair treatment agent smoothness test) 15 hairs were fixed at intervals of 1 mm from each other on a glass slide. The hair treatment agent was sprayed for five seconds on the hair, which gave spray samples which were then placed on a tester for measuring the coefficient of friction with alternating motion produced by KATO-TEC. A sheet of collagen paper not

  coated was installed and subjected to a load of 30 g / cm2.

  The resulting assembly was subjected to five alternative movements to determine the average value of the five

  coefficient values (MIU). Regarding the varia-

  measurement, the above operation was repeated three

  times to get an average value.

  (Affinity test for skin and hair) The ability to spread during application, the oily feeling and the feeling of hydration during application as well as the feeling of application, as

  that assessment criteria were assessed by 30 determina-

* scorers according to the following criteria: (Evaluation values) excellent 4 points good 3 points acceptable 2 points bad 1 point very bad O point (Judgment) average value of 3.0 to 4.0 O average value of 2, 0 to 3.0 o mean value from 1.0 to 2.0 A mean value from 0.1 to 1.0 X The results are presented in tables 14 to 21.

  14 naturally occurring amino acids. Among these amino-

  acids, only glycine has no L-isomeric form,

  other amino acids being in the L form. The N- derivatives

  acylated can also be in the form of salts. The pigments and diluent pigments obtained in the present invention generate a smooth tactile sensation and an extremely smooth tactile sensation when used in cosmetic products, which generates a satisfactory sensation when applied to the skin and hair and excellent affinity for the skin or hair. By applying the pigments and diluting pigments (spray) of the present invention, it is possible to obtain products

  cosmetics with these superior properties.
