Description

Technical Field

[0001] The present invention relates to hair cosmetics, and particularly to hair cosmetics that can impart smoothness during rinsing, smoothness during styling, a good sense of cohesion during styling, and no stickiness during styling.

Background Art

[0002] It is known that hair is damaged by chemical treatments such as hair coloring, bleaching, and permanent waving, and the good texture that healthy hair originally has is impaired. In addition to feeling poor finger combability due to hair squeaking and catching during rinsing, or feeling poor cohesion due to hair spreading during styling after drying, problems such as feeling poor finger combability due to hair frizz and catching are known.

[0003] In order to reduce the influence of the above-mentioned damage, the hair cosmetic of Patent Document 1 discloses that by containing a cationic surfactant, a higher alcohol, a silicone compound containing a phosphate group, and an amino-modified silicone, it can improve the persistence of slipperiness, the persistence of cohesion, and the lack of stickiness in the hair during styling.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, while Patent Document 1 examines the persistence of smoothness, manageability, and lack of stickiness in the finished hair, it was not entirely satisfactory. Furthermore, it did not examine how easily the fingers can comb through the hair during rinsing, and therefore did not simultaneously satisfy the requirements of smoothness during rinsing, smoothness of the fingers during the finished hair, good manageability, and lack of stickiness during the finished hair, leaving room for further research.

[0006] Therefore, the object of the present invention is to provide a hair cosmetic that can provide smoothness to the fingers during rinsing, smoothness to the fingers during the finished hair, good manageability during the finished hair, and no stickiness during the finished hair. [Means for solving the problem]

[0007] The inventors have selected (A) one or more selected from dimethyldiallylammonium chloride / acrylamide copolymer, polydimethylmethylenepyrrolidinium chloride, dimethyldiallylammonium chloride / acrylic acid copolymer, or acrylamide / acrylic acid / dimethyldiallylammonium chloride copolymer, (B) one or more selected from O-[2-hydroxy-3-(trimethylammonio)propyl]guar gum chloride or O-[2-hydroxy-3-(trimethylammonio)propyl]hydroxyethylcellulose chloride, and (C) aminopropyldimethicone, amodimethicone, or bis-methyldimethicone. We have discovered that a hair cosmetic can be obtained that provides smoothness when rinsing, smoothness when finished, manageability when finished, and lack of stickiness when finished, by providing a hair cosmetic that contains one or more selected from tearyl amodimethicone and (D) linoleamidopropyl PG-dimonium chloride phosphate dimethicone, wherein the content of component (A) is 0.04 to 1.7% by mass, the content of component (B) is 0.05 to 2% by mass, the content of component (C) is 0.05 to 10% by mass, and the content of component (D) is 0.06 to 2.5% by mass, and thus the present invention has been completed.
