Emulsion based hair cosmetic

Abstract

Provided is an emulsion based hair cosmetic containing (A) a cationic surfactant, (B) a higher alcohol, (C) L-histidine, (D) L-arginine, and (E) 0.1-0.5 mass% of a water-soluble polymer compound, wherein the total compounded amount and the mass ratio of the components (C) and (D) are: (C) 0.01-0.5 mass%, (D) 0.01-0.5 mass%, and (C) + (D) = 0.05-0.6 mass%; and (C) / (D) = 0.2-5.

Description

technical field [0001] The present invention relates to an emulsified hair cosmetic having excellent hair internal restoration and emulsification stability. Background technique [0002] Due to perm treatment, dyeing treatment, aging, etc., problems such as hollowing inside the hair, roughness and curling become obvious. Conventionally, there are known techniques for moisturizing the hair and suppressing frizz by using emulsified hair cosmetics such as rinse-off conditioners and hair-conditioning creams to penetrate the hair with low-molecular-weight amino acids (Japanese Patent Laid-Open No. 2007-8884 Publication No. 2011-84584, Japanese Patent Laid-Open No. 2011-195553). [0003] However, in order to penetrate the amino acid into the hair, it is necessary to increase the blending amount of the amino acid, and if the blending amount of the amino acid is too large, the emulsion stability will deteriorate. Therefore, in amino acid-containing emulsification-type hair cosmeti...

Problems solved by technology

[0003] However, in order to penetrate the amino acid into the hair, it is necessary to increase the mixing amount of the amino acid, and if the mixing amount of the amino acid is too large, the emulsion stability will deteriorate

Therefore, in emulsified hair cosmetics containing amino acids, it is difficult to achieve both emulsification stability and penetrability of amino acids into the hair.
