Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hair cosmetic that has excellent elongation during use and imparts excellent smoothness to the hair. Normally, hair contains animal and vegetable oils such as hair creams and hair oils, as well as secretions from the hair itself. However, if you wash your hair with soap or synthetic detergent, more of these oils and fats will be removed than necessary.As a result, your hair will not lose its smoothness after washing. This results in a rough, stiff feel, which makes it difficult to comb, making it easier to get frizz and split ends.

In order to eliminate such inconveniences, various hair cosmetics have been developed and used as hair treatment agents after hair washing. These hair cosmetics include dialkyl dimedelammonium chloride and alkyltrimethylammonium chloride C.
The main active ingredients are two representative quaternary ammonium salts.

There are two types of ammonium salts: those that are poorly soluble in water and those that are easily soluble in water. Correspondingly, hair cosmetics C; are available in ``rinsing type'' and ``non-rinsing type''. To prevent the hair from squeaking and tangling after washing, etc., and to improve the finish when it is dry (the second is the above ammonium The salt must be adsorbed to the hair, but conventional hair cosmetics have been unsatisfactory due to problems with the faj152 properties and adsorption properties of the ammonium salts, no matter how they are used.

In particular, the elongation during use and the smoothness of the hair when finished were extremely inadequate.

The present invention was made under the above circumstances, and an object of the present invention is to provide a hair cosmetic that has excellent elongation during use and imparts excellent smoothness to hair.

That is, the hair cosmetic of the present invention contains mono-N-long chain acyl basic amino acid lower alkyl ester H, PFI C-N
R* (wherein, R is an alkyl group having 12 to 22 carbon atoms, R1 is -CH, C00X or -CH, CH, 80,
and X is HaNa or K. ), the blending ratio (m/n) is 115 to 10/1, and the blending amount (m+1) is 0.1 to b Hereinafter, the hair cosmetics of the present invention will be explained in detail.

As the lower alkyl ester salt of a mono-N-long chain acyl basic amino acid which is the first essential component of the present invention, those shown in Japanese Patent Publication No. 51-22055J are used.

That is, the basic amino acid components include natural amino acids such as ornidene, lysine, and arginine, as well as synthetic amino acids such as α,-IP-cyaminobutyric acid, and these are either optically active or racemic. Good too.

The acyl group is a saturated or unsaturated unsaturated or synthetic fatty acid residue having 8 to 22 carbon atoms, preferably 12 to 18 carbon atoms, and examples of such acyl groups include lauroyl group, myristyl group, noramitoyl group, In addition to single fatty acid residues such as stearoyl groups, there are natural mixed fatty acid residues such as coconut oil fatty acid residues and bovine fatty acid residues. Suitable lower alkyl ester components include methyl ester, ethyl ester, clobyl ester, ff ester, pentyl ester, hexyl ester, heptyl ester, and octyl ester. In addition, organic acid salts such as %/N-long-chain acyl basic amino acid esters, pyroglutamine I, and other organic acid salts are used. Among these, acidic amino acid salts are expected to have a nutritional effect on hair. DL- or optically active pyroglutamate is preferred because it also acts as a wetting agent.

The effects of the present invention cannot be obtained using only the ester salts described above. Therefore, the hair cosmetic of the present invention has the effects of the present invention by blending the ester salt with a highly safe anionic surfactant as a second essential ingredient to form an econgrex (aggregate).・R1-C-N-R1 (wherein R is an alkyl group having 12 to 22 carbon atoms, R1 is -CH, C00X or -CH,CH,
S O,X and X is H,N! Or K. ) is an anionic surfactant represented by Such anionic surfactants include lauroyl sarcosine, myristoyl tyrcosine, balmitoyl sarcosine, stearoyl tyrcosine, beheroyl sarcosine, N-cocoyl mebuturine, N-myristoylmethyl taurine, N-noyalumitoyl Methyl taurine.

There are N-stearoylmethyltaurine, N-beheroylmethyltaurine, and salts thereof.

These anionic surfactants can be used alone or in combination of two or more. Among these surfactants, particularly preferred are N-myristoylmedeltaurinsome, N-lauroylmedeltaurin, lauroylcontainer, and the like.

The blending amount of the 7-ion surfactant is preferably 0.05 to 5% by weight, more preferably 0.1 to 3% by weight based on the hair cosmetic material.

In the hair cosmetic of the present invention, the weight ratio of the lower furkyl ester salt of a mono-N-long chain aryl basic amino acid to the anionic surfactant must be in the range of 115 to 10/1. Moreover, the preferable range is 1/4 to 4/1. If this weight ratio is less than 115, the adsorption of the hair cosmetic to the hair C deteriorates, and the ability to impart smoothness to the hair C is not exhibited, which is not preferable. On the other hand, if the above weight ratio exceeds 10/l, the hair cosmetic will not elongate when used.

The total amount of both components is 0.1 to 15% by weight, preferably 0.1 to 10% by weight. If it is less than 0.1% by weight, the effect of the present invention will not be exhibited, and if it exceeds 15% by weight,
The smoothness of the hair deteriorates, which is not desirable.

The hair cosmetics of the present invention (:) can be blended with other ingredients within a range that does not affect the effects of the present invention.

Such optional ingredients include the following substances: Quaternary ammonium salts of monoalkyl type or dialkyl type such as stearyltrimethylammonium chloride, hydrogenated tallow alkyltrimethylammonium chloride, eicosyltrimethylammonium chloride, heneicosyltrimethylammonium chloride; alginate furopylene gelicol ester, sodium alginate, alginate Colloid, pyroglutamate monostearin,
-Loglutamic acid monoolein, higher fatty acids, oxycanosyponic acid.

It is also possible to incorporate the following general-purpose ingredients. Hydrocarbons such as petrolatum and olefin oligomer; isopropyl myristate, isopropyl noylmite), stearyl stearate, octerdodenyl myristate.

Esters such as octyldodecyl oleate and tridaryceride 2-ethylhexanoate; higher alcohols such as cetanol, stearyl alcohol, cetostearyl alcohol, behenyl alcohol, yohyeldecanol; glyceryl monostearate, sorbitan mononodalmitate, 4-lyoxyethylene Cether ether.

4 emulsifiers such as lyoquine ethylene stearate and polyoquine ethylene sorbitan monolaurate; cellulose fat conductors such as dimethyl cellulose, hydroxylethyl cellulose, hydroxyl (/7') cellulose and cationized cellulose; Viscous agents; humectants such as ethylene glycol-propylene glycol, 1,3-butylene glycol, glycerin and sorbitol; and other solvents, disinfectants.

It is a small amount of ingredients such as fragrances.

The hair cosmetic composition of the present invention can be used for various hair treatment applications such as hair rinses, spray-type or dispenser-type hair conditioners, and hair lotions.

The hair cosmetic of the present invention exhibits excellent elongation and smoothness of the hair when applied to either type C ("rinsing type" or "non-single type").
