AI Technical Summary

Technical Problem

Existing hair cleansers with amino acid-based surfactants face challenges in achieving suitable viscosity, maintaining transparency at low temperatures, and ensuring foam spreads over a wide area during hair washing, particularly for long hair.

Method used

A hair cleansing composition comprising specific ratios of components (A) to (E), including a surfactant represented by Formula (1), an anionic surfactant, an amphoteric surfactant, and a compound represented by Formula (2), along with water, to achieve suitable viscosity, low-temperature stability, and wide foam distribution.

Benefits of technology

The composition maintains transparency at low temperatures and ensures foam spreads effectively over a wide area during hair washing, providing a pleasant cleansing experience.

Abstract

To provide a hair washing agent composition that has a viscosity suitable for use as a washing agent, ensures stability under low temperatures, and allows foam to spread over a wide area during hair washing.SOLUTION: A hair washing agent composition contains: a component (A) which is a surfactant represented by formula (1); a component (B) which is an anionic surfactant other than the component (A); a component (C) which is an amphoteric surfactant; a component (D) which is a compound represented by formula (2); a component (E) which is a compound represented by formula (3) or a salt thereof; and water. Based on the entire hair washing agent composition, a content of the component (A) is 0.1 to 10 mass%, a content of the component (B) is 1 to 20 mass%, a content of the component (C) is 1 to 20 mass%, a content of the component (D) is 0.1 to 5 mass%, and a content of the component (E) is 0.001 to 1.0 mass%. A mass ratio of (A) / (B) is from 0.1 to 0.9, a mass ratio of {(A)+(B)} / (C) is from 0.2 to 4, and a mass ratio of (A) / (E) is from 15 to 300.SELECTED DRAWING: None
