Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hair cosmetic composition which has an excellent moisturizing effect and consequently imparts good softness to the hair.

[Prior Art] As moisturizers conventionally blended in hair cosmetics, glycerin, propylene glycol, urea, sorbitol,
Alkylene oxide adducts of alcohol are known.

[Problems to be Solved by the Invention] Hair cosmetics using these moisturizers provide softness to the hair due to its moisturizing effect for so-called healthy hair that is less damaged by perms, bleaches, hair dies and the like. Although it can be imparted, conventional moisturizers cannot suppress the evaporation of water from the hair and cannot impart the desired softness to so-called damaged hair that is significantly damaged.

[Means for Solving Problems] The present inventors focused their attention on the above-mentioned problems, and as a result of earnest studies on a moisturizing agent that gives good flexibility to damaged hair, as a result, an extract extracted from a specific plant The present invention has been accomplished by finding that the addition of a polyhydric alcohol and a polyhydric alcohol to a hair cosmetic composition can suppress water vaporization from the hair and impart preferable flexibility to damaged hair.

That is, the present invention relates to loquat ( Eriobotrya ja - ponica Lind
A hair cosmetic composition comprising 0.001% by weight or more of the extract extracted from l.) and one or more polyhydric alcohols selected from dipropylene glycol, polyethylene glycol and glycerin. It is provided.

Hereinafter, the configuration of the present invention will be described in detail.

The extract used in the present invention is loquat ( Eriobotrya j
a- ponica Lindl.) bark, leaves, pulp, seeds, and rhizome dried products are obtained by an ordinary method using water, a hydrophilic organic solvent, a water-containing hydrophilic organic solvent, another organic solvent or liquid oil as an extraction solvent. be able to. As a particularly preferred solvent,
Water, ethanol, glycerin, propylene glycol,
It is 1.3-butylene glycol, and these solvents can be used either alone or as a mixture. In addition, the extraction step is performed by using an equal amount or more of a solvent for the dried loquat material as a raw material, at room temperature for 1 hour or more, and if necessary, heating. As the extract, the extract containing the extraction solvent is used as it is, or the extraction solvent is removed. The amount of loquat extract to be incorporated in the hair cosmetic composition of the present invention is preferably 0.001 to 10% by weight based on the total amount of the hair cosmetic composition as a dry weight.

In the present invention, the above extract is used in combination with one or more polyhydric alcohols selected from dipropylene glycol, polyethylene glycol and glycerin. These polyhydric alcohols are used in the amount of 0.
Used from 1 to 30% by weight.

The hair cosmetic composition of the present invention further comprises known cosmetic ingredients in addition to the above essential ingredients, such as esters of fatty acids with low alcohols and polyhydric alcohols, paraffin hydrocarbons, fatty acids, linear or branched higher alcohols, alkyl glycerin ethers, and silicones. Oils such as oils and polyoxyethylene alkyl ethers are acetates, higher fatty acid salts, N-acyl amino acid salts, alkyl sulfates, alkyl allyl sulfates, α-
Olefin sulfonate, acyl isethionate, alkyl sulfosuccinate, N-acylmethyl taurine salt,
Anionic sea surface active agents such as polyoxyethylene alkyl ether sulfates, alkyl phosphates, polyoxyethylene alkyl ether phosphates, etc., and polyoxyethylene alkyl ethers, esters of fatty acids with lower alcohols and higher alcohols, or ethylene thereof. Oxide adduct, polyoxyethylene polyoxypropylene alkyl ether, polyoxyethylene alkylphenyl ether, polyoxyethylene alkylamine,
Nonionic surfactants such as fatty acid alkanolamides, ethylene oxide adducts of fatty acid and polyvalent alkyl esters and hydrogenated products thereof, and amphoteric surfactants such as carboxybetaine, sulfobetaine and imidazoline derivatives, and monoalkyltrimethyl Cationic surfactants such as ammonium chloride, dialkyldimethylammonium chloride, monoalkenyltrimethylammonium chloride, lower alcohols, anionic, cationic and nonionic water-soluble polymers, vitamins and other drugs, Preservatives, zinc pyrithione, trichlorocarbanilide, piroctone olamine, bactericidal agents such as sulfur, pH adjusters, ultraviolet absorbers, antioxidants, sequestering agents, fragrances, dyes, nylon, polyethylene, cellulose, chitin, Inorganic compounds, etc. By appropriately blending the sexual fine powder or the like, for example Shiyanpu, hair rinse, hair treatment, hair tonic, is used as a hair styling agent or the like.

[Effects of the Invention] The hair cosmetic composition of the present invention prevents water vaporization of so-called damaged hair, which is significantly damaged by perm, bleach, hair dye, etc., and imparts preferable softness.

EXAMPLES Next, the present invention will be described in detail with examples.

Prior to the examples, the test method and evaluation method adopted in each example will be described.

Hair flexibility evaluation method A panel of hair damaged by perm was used in the same manner as a sample is normally used, and the flexibility was 1 to 5 in sensory evaluation.
Scored by points. The number of panels is 5 for each sample,
Evaluation was made in 3 stages based on the average score of 5 persons.

⊚: 4 points or more, remarkable flexibility is recognized.

Δ: 2 points or more and less than 4 points, some flexibility is recognized.

X: less than 2 points, flexibility is not recognized.

The loquat extract used in each Example and Comparative Example was produced by the method described below.

To 10 parts of dried loquat leaves, 100 parts of a 1: 9 mixed solvent of water and 1,3-butylene glycol was added, and after soaking at room temperature for 10 days, this was filtered to obtain 90 parts of an extract. This extract was used without removing the solvent.

Examples 1 to 4 and Comparative Examples 1 to 3 were used to prepare shampoos having the composition shown in Table 1.
The effect of imparting hair flexibility was examined.

As shown in Table 1, this example showed an excellent effect of imparting hair softness.

Examples 5 to 6 and Comparative Examples 4 to 6 Hair rinses having the composition shown in Table 2 were prepared,
The effect of imparting hair flexibility was examined.

As shown in Table 2, this example showed an excellent effect of imparting hair softness.

Example 7 A hair liquid having the following composition was prepared by a conventional method.

95% Ethyl alcohol 50 Glycerin 5 Polyoxypropylene (40 mol) Butyl ether 15 Loquat extract 1 Fragrance 0.5 Water Residue This hair liquid showed an excellent effect of imparting hair softness.

Example 8 A hair cream having the following composition was prepared by a conventional method.
