Abstract

PROBLEM TO BE SOLVED: To obtain a composition for caring hair and a skin capable of giving a refreshing and wet feeling, and a moisted feeling after application as well as a smooth feel by mixing pantothenic acid compounds with specific keratin derivatives in a preferred ratio. SOLUTION: This composition is obtained by mixing (A) 0.1-20wt.% of pantothenic acid having characteristics of prevention of loss of hair, nutrition of a skin, etc., with (B) 0.001-20wt.% of keratin hydrolysate being a low-cost material. Pantothenic acid, pantothenyl alcohol, pantothenylethyl ether, etc., are exemplified as pantothenic acid compounds. Liquid hydrolysed keratin, keratin polypeptides, etc., are exemplified as keratin hydrolysate and molecular weights of them esp. preferably range from 500 to 10,000. It is more effective to mix pantothenic acid compounds with keratin hydrolysate in a ratio of (100-1):1, esp.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a cosmetic or cleaning composition to be applied to hair and skin.

[0002]

2. Description of the Related Art In recent years, the frequency of shampooing has increased in accordance with the improvement in cleanliness, and in addition to the basic function of cleaning and cleaning hair and scalp, the hair and scalp have a moist, moisturizing and smooth feeling. There is a demand for a shampoo which has an effect of giving the skin and a soap or a skin conditioner which has a function of giving a moist feeling, a moist feeling and a smooth feeling. To meet such demands, cosmetics and cleaning agents for hair and skin have been diversified, and many products have been developed.

[0003] Pantothenic acid compounds are also used in various cosmetics because they have properties such as hair loss prevention and nutritional supplementation to the skin. However, there was a drawback that there was an unpleasant stickiness. Therefore, in order to eliminate the sticky feeling, a cosmetic characterized by containing pantothenic acid and its analogs and lecithin (Japanese Patent Laid-Open No. 62-4215)
Has been proposed.

[0004] Keratin is also used to repair hair damage,
It is an inexpensive material that is known as a functional cosmetic raw material with good effects such as moisturizing and film formation, and has good safety, and is widely used in general. As a detergent containing keratin,
A shampoo composition containing a keratin substance-decomposing derivative (JP-A-57-85896) and the like can be found. However, these methods are not sufficient for the effect of giving a moist feeling, moisturizing feeling and smoothness to hair or skin, and there are products that can sufficiently satisfy the demands of moist feeling, moisturizing feeling and smooth feeling desired by consumers. It is not at present.

[0005]

SUMMARY OF THE INVENTION In diversifying compositions such as shampoos, soaps, facial cleansers, detergents, baths, etc., in addition to the cleaning function, a smooth feel during use on hair and skin, hair or skin There is a need for cosmetics and cleaning agents that have a moist, moisturizing, and smooth feeling. For example, by giving the hair a moist feeling, a moist feeling, and a smooth feeling, the hair can be combed, the hair can be easily adjusted, and tangles and split ends can be prevented.

[0006] The appearance of a product that satisfies these requirements and exhibits a more useful effect has been expected. An object of the present invention is to provide a shampoo and a soap that are expected to impart a refreshing moist feeling, a moist feeling, and a smooth feeling to hair and skin after use, in addition to smoothness during use, for hair and skin. And cosmetics and cleaning agents such as facial cleansers, detergents and baths.

[0007]

In order to solve the above-mentioned problems, the present inventors have conducted intensive studies to solve the above-mentioned problems. As a result, the present invention has been applied to cosmetics or cleaning agents such as shampoos, soaps, facial cleansers, detergents and baths. By using the pantothenic acid compound in an amount of 0.1 to 20% by weight and the keratin hydrolyzate in an amount of 0.001 to 20% by weight, the unpleasant stickiness of the pantothenic acid compound is improved, and it is applied to hair and skin. The present invention has found that, in addition to the smooth feel during use, an excellent effect of imparting a refreshing moist feeling, moisturizing feeling, and smooth feeling to the hair or skin after use can be obtained even more strongly than when formulated alone. Was completed.

The details will be described below. The pantothenic acid compound used in the present invention includes pantothenic acid, pantothenyl alcohol, pantothenyl ethyl ether, pantethine, calcium pantothenate, sodium pantothenate, D-pantothesaine, vantothenoyl-L-cysteine, and di-D-pantothenoyl-L -Cystine, D-pantothenoic acid-4-phosphate, D-pantothenoyl-L-cysteine-4-phosphate, di-D-pantothenoyl-L-cystine-4,4'-diphosphate, D-dicarbet Refers to one or more of ethyl xipanotothenate (bihuvanto). The addition amount is preferably from 0.1 to 20% (weight, the same applies hereinafter) of the total amount, more preferably from 0.5 to 5.0%. The addition amount is
If it is less than 0.1%, the expected moist feeling cannot be obtained, and if it exceeds 20%, a feeling of incongruity is felt during use, which is not appropriate.

Keratin is generally a vertebrate epithelial tissue,
That is, it is an insoluble protein having a high cysteine content, which is found as a constituent component of horns, nails, epidermis, hair, feathers, wool, and the like. The keratin hydrolyzate used in the present invention is generally a hydrolyzed keratin solution, a hydrolyzed keratin ethyl solution, a keratin polypeptide, or a hydrolyzed polypeptide, and preferably has a molecular weight of 500 to 10,000. If the molecular weight is less than 500, the intended effect is low, and if it exceeds 10,000, the properties are close to those of undecomposed keratin, and the effect is lost. The addition amount is preferably 0.001 to 20% of the total amount, more preferably 0.1 to 20%.
01 to 5.0%. If the amount is less than 0.001%, the desired effect cannot be obtained.
Solubility and dispersibility deteriorate. These keratin hydrolysates are hydrolysates of hair, wool, or the like as raw materials by an oxidation method, a reduction method, or an enzymatic method, and derivatives thereof, and various products are commercially available.

In addition, the compounding ratio of the pantothenic acid compound and the keratin hydrolyzate is 100-1: 1, preferably 10-10
A more favorable effect can be obtained by blending in a ratio of 5: 1. The amount of the blended mixture varies depending on the type, purpose and form of the composition, but is preferably 0.1 to 40% based on the total amount of the composition, and more preferably 3 to 10%. It is.

Further, the hair and skin composition of the present invention may contain a composition having other effects such as a moisturizing effect and a conditioning effect. Specific examples include polyoxyethylene sorbitan fatty acid esters, glycerin, propylene glycol, sorbit, hyaluron, and the like. As the composition for hair and skin of the present invention, cosmetics for hair, for example, shampoo, rinse, conditioner, hair styling, hair cream, etc., cosmetics used for skin, for example, body soap, soap, face wash,
Other household products such as lotions, emulsions, creams, packs, lipsticks, and the like, for example, dishwashing detergents, bath agents, toiletry products, pet products, and the like. The composition of the composition is not particularly limited, and any composition such as a solution, a solubilized, an emulsified, a powder-dispersed, a water-oil two-layer type, a water-oil-powder three-layer type can be used. It may be a type. These compositions of the present invention
Each can be manufactured by a known method.

[0012]

The effect exerted by the present invention imparts a fresh moist feeling, a moist feeling and a smooth feeling to the hair or skin after use, in addition to the smooth feel during use. For example, by giving the hair a moist feeling, a moist feeling, and a smooth feeling, the hair can be combed, the hair can be easily adjusted and tangling and split ends can be prevented, and if the skin is moistened and smooth, hands, elbows, and knees can be used. Bulkiness such as is improved.
