Description

Technical Field

[0001] The present invention relates to a personal care composition suitably used in at least one of skin cleansing agents, hair cleansing agents, and hair conditioning compositions.

Background Art

[0002] In recent years, for cleansing agent compositions for the body and hair, not only high detergency but also a cleansing agent composition with little irritation to the skin and excellent usability is desired, and it is required to have good foaming properties in order to reduce frictional damage.

[0003] Generally, detergents mainly use anionic surfactants and are combined with nonionic and / or amphoteric surfactants to enhance foaming and detergency. However, when washing, sebum components are excessively removed, and at the time of rinsing and finishing, there are problems such as a feeling of dryness and tightness on the skin, tangling and coarseness of the hair.

[0004] For example, in Patent Document 1, in order to improve washing effects such as foaming property, detergency, and foam quality, and usability such as a moist feeling after washing and conditioning effects, (A) 1 to 30% by weight of a higher fatty acid salt, (B) 0.1 to 20% by weight of a polyhydric alcohol, and (C) 0.01 to 5% by weight of an acrylic acid alkyl copolymer are contained in the detergent composition. However, at present, the detergent composition of Patent Document 1 has not reached a sufficient level in terms of imparting a moist feeling when the content of the surfactant is relatively high.

[0005] Further, in Patent Document 2, by blending an amphoteric polymer composed of a specific acrylic acid / dimethyldiallylammonium chloride / acrylamide copolymer and a cationic polymer such as poly(dimethylmethylenepiperidinium chloride), cationized cellulose, cationized guar gum, or a diallyl quaternary ammonium salt / acrylamide copolymer, a detergent composition having good foaming properties and a usability without a tight feeling has been proposed. Furthermore, Patent Document 3 proposes a shampoo composition that provides a good foaming sensation and gives hair a smooth feel when rinsing by combining a copolymer of dialkyldiallylammonium salt and cationized cellulose. However, while the compositions described in Patent Documents 2 and 3 provide a smooth feel during rinsing, they do not provide specific descriptions regarding the moisturizing effect in the finished product, and they fail to solve the problem of exhibiting a film-like and stiff feeling after drying, resulting in a poor user experience.

[0006] Furthermore, Patent Document 4 proposes a hair cosmetic containing (A) diethyl sebacate and (B) one or more selected from the group consisting of siloxane compounds, cationic polymer derivatives, plant extracts or presses, peptide derivatives, royal jelly or extracts thereof, in order to improve hair tangling after washing and enhance the conditioning effect. However, the hair cosmetic described in Patent Document 4 has not yet achieved satisfactory performance in achieving both improved moisturizing effect after drying and reduced film-like feeling and stiffness.

Advantages of the Invention

[0014] According to the present invention, it is possible to provide a personal care composition having good foaming properties, no stickiness and film feeling on hair and skin, and excellent moisturizing effect.

Modes for Carrying Out the Invention

[0015] The personal care composition of the present invention contains (A) 2,3 - butanediol, (B) fructan, and (C) a cationic polymer, and further contains other components as required.

[0016] <(A) 2,3 - butanediol> 2,3 - butanediol as component (A) is a known substance which is a kind of dihydric aliphatic alcohol. 2,3-Butanediol is butylene glycol obtained by fermenting carbohydrates with bacteria such as Klebsiella and Bacillus, and when its diacetate is thermally decomposed, butadiene can be obtained in a high yield. Therefore, it was studied for industrial production in various countries during the war. 2,3-Butanediol is present at 1 ppm to 500 ppm in a wide range of microbial cultures and fermented foods (such as beer, wine, bread, cheese, etc.), and is said to impart its flavor. Examples of the production bacteria used for fermentation by bacteria include Klebsiella pneumoniae, Bacillus polymyxa, B. subtilis, Aeromonas hydrophila, Serratia marcescens, and the like. There are three kinds of optical isomers of 2,3-butanediol: D(-)-, L(+)-, or meso-. The products obtained by fermentation vary depending on the bacteria, and mostly the meso form is obtained.

[0017] The content of 2,3-butanediol in component (A) is preferably 0.1% by mass to 20% by mass, more preferably 1% by mass to 15% by mass, still more preferably 3% by mass to 15% by mass, and particularly preferably 5% by mass to 10% by mass, based on the total amount of the personal care composition. If the content of 2,3-butanediol in component (A) is less than 0.1% by mass, a sufficient moisturizing feeling of the finish may not be obtained, and if it exceeds 20% by mass, deterioration of skin compatibility and stickiness may occur.

[0018] <(B) Fructan> Fructan is a general term for polysaccharides in which fructose is polymerized to sucrose by β(2→1) bonds and β(2→6) bonds, and it can have glucose at the end in addition to fructose. Examples of fructan include linear inulin-type fructan (β2→1 bond), levan-type fructan (β2→6 bond), branched graminan-type (β2→1 bond and β2→6 bond), and the like. Among these, inulin-type fructan is particularly preferred in terms of the smoothness of the finish. Inulin-type fructans are preferably characterized by having an average degree of polymerization of 13 to 23 and containing 95% or more by mass of inulin with a degree of polymerization of 5 to 29 relative to 100% by mass of total inulin, due to their high water solubility. Commercially available inulin-type fructans can be used, such as Inulin-SC (manufactured by Nippon Seika Co., Ltd.). "Inulin-SC" has an average degree of polymerization of 13 to 23 and contains 95% by mass or more of inulin with a degree of polymerization of 5 to 29 relative to 100% by mass of total inulin.

[0019] The fructan content of component (B) is preferably 0.01% to 5% by mass, more preferably 0.05% to 3% by mass, and even more preferably 0.1% to 1% by mass, based on the total amount of the personal care composition.

[0020] <(C) Cationic polymer> A cationic polymer is a polymer that has substituents that become cationized when dissolved in water. Examples of cationic polymers for component (C) include cationic polysaccharides and acrylic cationic polymers. Among these, cationic polysaccharides are preferred.

[0021] Cationic polysaccharides are modified polysaccharides in which a cationic group is introduced into the polymer backbone of a polysaccharide. Examples include cationized guar gum, cationized tara gum, cationized fenugreek gum, cationized locust bean gum, cationized cellulose, cationized hydroxyethylcellulose, cationized hydroxypropylcellulose, cationized carboxymethylcellulose, cationized cassia gum, cationized xanthan gum, cationized starch, or derivatives thereof. These may be used individually or in combination of two or more. Among these, cationized cassia gum or its derivatives are particularly preferred in terms of the absence of a film-like feeling in the finished product and good foaming properties. Cassia gum is a polysaccharide obtained by crushing the endosperm of the seeds of the legume plant Cassia tora or Cassia obtusifolia.

[0022] Examples of acrylic cationic polymers include dimethyldiallylammonium chloride-acrylamide copolymer, dimethyldiallylammonium chloride-acrylic acid copolymer, and vinylpyrrolidone-quaternized dimethylaminoethyl methacrylate copolymer.

[0023] The content of the cationic polymer in component (C) is preferably 0.02% to 2% by mass, more preferably 0.05% to 2% by mass, and even more preferably 0.1% to 1% by mass, based on the total amount of the personal care composition. If the content of the cationic polymer in component (C) is less than 0.02% by mass, sufficient lathering, smoothness during rinsing, and moisturizing feeling in the finish may not be obtained, and if it exceeds 2% by mass, a film-like feeling may develop, resulting in a poor finish.

[0024] <Other ingredients> The personal care composition of the present invention may contain other components as needed, in addition to components (A) to (C) above, as long as they do not impair the purpose and effects of the present invention. Specific other components are listed below. In the following description, POE is an abbreviation for polyoxyethylene, and POP is an abbreviation for polyoxypropylene.
