摘要:
Provided is a novel surfactant which is less irritating to the skin or the mucous membrane than prior art surfactants, which exhibits excellent conditioning effects and fabric softening effects, and which can be widely used in a toiletry or detergent composition. Basic amino-acid derivatives or salts thereof obtained by reacting glycidyl ethers with basic amino acids or salts thereof are incorporated into a toiletry or detergent composition or a conditioning agent.

摘要:
A detergent composition which comprises (A) an N-acyl amino acid salt of an amino acid selected from glycine, alanine and .beta.-alanine where the acyl group is a saturated or unsaturated fatty acid residue having 8 to 20 carbon atoms and (B) a higher fatty acid salt at a Component (A)/Component (B) weight ratio of 99.5/0.5 to 90/10, and another detergent composition derived from the above composition, which comprises further a higher alcohol and/or polyhydric alcohol. According to the present invention, properties of N-acyl amino acid salts as detergents can be improved.
摘要:
There are provided cosmetics which have not only a reduced effect on the “gleam” caused by irregular light reflection but also a reduced effect on “stickiness” based on an oil raw material, giving a good feeling during use such as spreadability, etc., and being excellent in the sustaining of the makeup effect. There are used N&egr;-long chain acyllysine crystals whose average diameter or mode diameter lies in the range of 3˜15 &mgr;m without being subjected to the mechanical pulverization.
