Problems solved by technology

However, as we age, the hair loses its strength, elasticity, and looseness, which is not ideal
In addition, with the increase of gray hair, frequent hair dyeing will cause hair damage, especially wet hair is easy to entangle with each other, prone to hair breakage, split ends
On the other hand, when the existing hair cosmetics impart the repairing effect to the hair, it is unfavorable that the hair loses its fluffy feeling due to stickiness and stickiness caused by oils and the like.
In addition, in conventional hair cosmetics containing cationic polymers or specific vinyl copolymers (see Patent Document 1: Japanese Patent Laid-Open No. 2006-347973, Patent Document 2: Japanese Patent Laid-Open No. 2007-31615 ), during the drying process of wet hair, the comb and fingers are not sufficiently dredged, resulting in broken hair and split ends

[0090] [modulation method]

[0091] According to the composition shown in Tables 2-9, the rinse-off hair conditioner was prepared by the following method. Specifically, the mixed oily components were dissolved in a water bath at 80° C., and (C) polyhydric alcohol or sugar alcohol was added, mixed, and homogenized to form a gel liquid crystal. The (A) acrylic polymer is added to this gel liquid crystal, and it further mixes uniformly. Then, the aqueous phase in which (B) an organic carboxylic acid having 8 or less carbon atoms or a salt thereof, and a water-soluble component are dissolved is added to perform phase transfer emulsification. It was further cooled to room temperature while stirring. The pH was adjusted to 3-4 with sodium hydroxide. Moreover, pH and viscosity of the obtained rinse-off conditioner were measured by the following method, and the following evaluation was performed.

Abstract

Disclosed is a hair cosmetic comprising 0.1 to 2 mass% of (A) an acrylic polymer, 0.1 to 3 mass% of (B) an organic carboxylic acid having 8 or less carbon atoms or a salt thereof, and 10 to 50 mass% of (C) a polyhydric alcohol or a sugar alcohol, wherein the mass ratio of the content of the component (A) to the content of the component (B) (i.e., a (A) / (B) ratio) is 0.20 to 8.00, and wherein the acrylic polymer (A) comprises 70 to 95 mol% of a monomer unit represented by general formula (1) and 5 to 30 mol% of a monomer unit represented by general formula (2) [in the formulae, R1 represents a hydrogen atom or a methyl group; R2 represents a hydrogen atom or a group -CH2OH; A represents an oxygen atom or -NH-; R3 represents a hydrogen atom or a methyl group; and M represents a hydrogen atom, an alkali metal atom, an ammonium or an amine].

Description

technical field [0001] The present invention relates to hair cosmetics suitable for hair that loses volume, strength, and elasticity with age. Background technique [0002] In an aging society, the need to live a healthy and comfortable life is increasing. However, as we age, hair loses its strength, elasticity, and less volume, which is not ideal. In addition, with the increase of gray hair, frequent hair dyeing treatment will cause hair damage, especially wet hair is easy to entangle with each other, prone to hair breakage and split ends. On the other hand, when the conventional hair cosmetics impart repairing effects to the hair, the stickiness and stickiness caused by oils and the like occur, and the hair loses its fluffy feeling, which is unfavorable. In addition, in conventional hair cosmetics containing cationic polymers or specific vinyl copolymers (see Patent Document 1: Japanese Patent Laid-Open No. 2006-347973, Patent Document 2: Japanese Patent Laid-Open No. 20...
