Description

[Technical Field]

[0001] The present invention relates to a hair cosmetic composition. More specifically, the present invention relates to a hair cosmetic composition that has excellent spreadability upon application, smoothness upon rinsing, and a manageable and moist finish. [Background technology]

[0002] With the recent popularity of hair coloring and perms, hair damage care has become increasingly important. Among hair coloring agents, permanent hair dyes such as oxidative hair dyes and hair lightening bleaches generally contain alkaline agents, which place a heavy burden on hair and cause it to become rough and stiff after treatment. Perm agents also place a similar burden on hair. In addition, there are various other factors that can damage hair in everyday life, such as daily brushing and the use of hair irons, and this has led to an increasing demand for hair cosmetic compositions such as rinses and hair conditioners for hair care.

[0003] Consumers demand that hair cosmetic compositions such as rinses and hair conditioners provide a good feeling when used, such as smoothness when running fingers through the hair after rinsing, and a good texture when finished, such as a smooth feel and manageability when touching the hair after treatment.

[0004] To solve these problems, polymer compounds such as dimethyldiallylammonium chloride-acrylic acid copolymer, silicone compounds, cellulose compounds, etc. are blended.

[0005] Patent Document 1 proposes a hair treatment agent containing hydroxyethyl cellulose and / or hydroxypropyl cellulose and polyquaternium-52, which allows for smooth finger-combing when rinsing and leaves hair feeling smooth and manageable when touched. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-82169 Summary of the Invention [Problem to be solved by the invention]

[0007] However, although the hair treatment agent in Patent Document 1 has been examined for its ease of running fingers through the hair when rinsing, it has not been examined for its spreadability upon application, nor has it been examined for its manageability and moisturized feel, which are important factors in hair finish.

[0008] Therefore, an object of the present invention is to provide a hair cosmetic composition that spreads well when applied, feels smooth to the touch when rinsed off, and leaves hair with a good manageable and moist finish. [Means for solving the problem]

[0009] As a result of extensive research, the present inventors have found that the above-mentioned problems can be solved by a hair cosmetic composition comprising (A) dimethyldiallylammonium chloride-acrylamide copolymer, (B) acrylamide-acrylic acid-dimethyldiallylammonium chloride copolymer, (C) O-[2-hydroxy-3-(trimethylammonio)propyl]hydroxyethylcellulose chloride, (D) O-[2-hydroxy-3-(trimethylammonio)propyl]guar gum chloride, (E) hydroxyethylcellulose, (F) polypropylene glycol, (G) propylene glycol, dipropylene glycol, and glycerin, wherein the content of component (A) is 0.05 to 0.5% and the content of component (B) is 0.1 to 0.7%, and have completed the present invention. [Effects of the Invention]
