Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a good foaming property and a feeling of foam, and has a good washing effect on hair and excellent hair after washing and drying. The present invention relates to a shampoo composition having a texture. [0002] With the diversification of hair care in recent years, the functions required of shampoos have become diversified and complicated. In particular, hair colors and permanents are established, and the chance of adversely affecting the texture of hair is increasing. Against this background, shampoos are required to have an excellent hair texture after washing and drying, specifically, a supple and moist feel, in addition to the conventional washing effect. As components that improve the texture of the hair after washing and drying, oil components such as hydrocarbon oils, lanolin derivatives and silicone oil derivatives, moisturizing components such as propylene glycol and glycerin, and cationic polymers are known. ing. [0003] However, the above-mentioned components do not always show a sufficient effect. That is,
Oily components such as hydrocarbon oils, lanolin derivatives, and silicone oil derivatives have the effect of improving the texture of the hair after shampooing and drying, but are difficult to formulate into shampoos, or by blending them. There are drawbacks such as impairing the foaming properties of the shampoo itself. In addition, most of moisturizing components such as propylene glycol and glycerin are washed away by rinsing, and the effect cannot be sufficiently exhibited. Further, the cationic polymer improves finger passage at the time of rinsing, but has an insufficient effect of supple hair after washing and drying. Accordingly, the present invention has been made in view of the above circumstances, and has good foaming properties and foam feeling,
An object of the present invention is to obtain a shampoo composition having both excellent washing effect and excellent hair texture after washing and drying hair. [0005] The present inventors have conducted intensive studies to achieve the above object, and as a result, a shampoo composition containing polyglycerin in a shampoo base has been developed.
The inventors have found that the above-mentioned problems can be solved, and have completed the present invention. That is, the present invention provides (A) at least one or more surfactants selected from anionic surfactants, amphoteric surfactants and nonionic surfactants, and (B) average polymerization calculated from the hydroxyl value. The present invention relates to a shampoo composition containing a polyglycerin having a degree of 3 or more. Hereinafter, the present invention will be described in detail. Surfactants used as a shampoo base used in the present invention are anionic surfactants, amphoteric surfactants and nonionic surfactants usually used for shampoos, and use at least one or more selected from them. However, a combination of two or more types is preferable from the viewpoints of foaming properties, foam persistence, and the like. Examples of these surfactants include anionic surfactants such as alkyl sulfates, polyoxyethylene alkyl ether sulfates, alkyl amide sulfates, alkyl phosphates, alkyl amide phosphates, and polyoxyethylene alkyl ether phosphates. Acid salts, N-acyl taurine salts, N-acyl amino acid salts and the like. Examples of the amphoteric surfactant include an alkyl betaine type, an amido betaine type, and an imidazoline type amphoteric surfactant. Examples of the nonionic surfactant include polyglycerin fatty acid ester, polyoxyethylene fatty acid ester, and polyoxyethylene alkyl ether. , Alkylolamide, sucrose fatty acid ester, polyoxyethylene fatty acid amide, polyoxyethylene alkylamine, alkylglucoside and the like. [0008] In the shampoo composition of the present invention, the above surfactant is added to the shampoo composition in an amount of 5.0 to 30.
0% by weight (in terms of solid content of surfactant), preferably 1%
0.0 to 25.0% by weight (based on the solid content of the surfactant) is blended. If the amount is less than 5.0% by weight, the functions required as a shampoo, such as foaming properties and detergency, become insufficient. Further, if the content exceeds 30.0% by weight, inconvenience occurs in rinsing, which is not preferable in use. The polyglycerol having an average degree of polymerization calculated from the hydroxyl value of 3 or more used in the present invention includes triglycerin, # 350, # 500, and # 750 (all of which are polyglycerol manufactured by Sakamoto Yakuhin Kogyo KK). The average degree of polymerization calculated from the hydroxyl value corresponds to 3, 4, 6, or 10), and one or more of these are used. The shampoo composition of the present invention contains 1.0 to 10.0% by weight, preferably 3.0 to 7.0% by weight of polyglycerin having an average degree of polymerization of 3 or more calculated from the above hydroxyl value.
0% by weight is blended. If it is less than 1.0% by weight, the suppleness and moist feeling of the hair after washing and drying become insufficient,
The desired shampoo composition cannot be obtained. Also, 10.0
If it is added in excess of weight%, it takes a long time to foam, and the foam is heavy. Further, the shampoo composition of the present invention may contain, as desired, various additive components to be added to conventional shampoos, in addition to the above-mentioned essential components, as long as the object of the present invention is not impaired. it can. The additives include inorganic salts such as sodium chloride and sodium sulfate, propylene glycol, glycerin,
Polyhydric alcohols such as diglycerin, antioxidants such as dibutylhydroxytoluene and tocopherol acetate, ultraviolet absorbers, hydrolyzed collagen derivatives, hydrolyzed silk derivatives, hydrolyzed keratin derivatives, mucopolysaccharides such as hyaluronic acid and chondroitin, plants Extracts, crude drugs, organic acids and salts thereof such as citric acid and succinic acid, amino acids such as glycine and alanine, preservatives, bactericides, flavors and the like are included. These additional components can be appropriately blended alone or in combination of two or more. The shampoo composition of the present invention can be produced according to a conventional method, and can be obtained, for example, by heating and stirring and dissolving all components to be blended. The present invention will be described below in more detail with reference to examples, but the present invention is not limited to these examples. Examples 1 to 6 and Comparative Examples 1 to 5 Shampoo compositions were prepared according to the compositions shown in the tables and evaluated by the following methods. The results are shown in Tables 1 and 2. (Evaluation method) 1) Using 30 shampoo compositions prepared in Examples and Comparative Examples for 30 healthy female panelists, "foaming", "foaming", "rinsing", and hair washing and drying The following items of "cleanability" of the scalp and hair, "suppleness" of the hair, and "moistness" were scored out of 100 points, and the average score was calculated and evaluated according to the following criteria. 2) Stability After the compositions prepared in Examples and Comparative Examples were left in a thermostat at a temperature of 0 ° C. and 50 ° C. for one month, the state was visually observed.
Evaluation was made based on the following evaluation criteria. ：: No change in state X: Separation part is observed. [Table 1] [Table 2] The shampoo compositions of Examples 1 to 6 exhibited the desired performance in terms of feeling of use and stability. On the other hand, Comparative Example 1
The shampoo compositions of Nos. To 5 were unsatisfactory in use feeling and stability. EFFECT OF THE INVENTION The shampoo composition of the present invention has a good foaming property and a feeling of foam, and also has an excellent washing effect on hair and an excellent texture of the hair after washing and drying. It relates to a composition.
