Problems solved by technology

However, this technology only discloses the effect of amide sulfate ester-based surfactants as the main detergent base and the addition of a small amount of coconut oleic acid N-methylethanolamide on detergency and foaming properties
Therefore, there is no mention of obtaining a detergent composition that produces little skin irritation and has a rich lather

Abstract

Disclosed is a detergent composition characterized by low skin irritation, good foamability, easy handling at the time of manufacture, and excellent stability when stored as a product. The detergent composition is a composition which contains a specific amount of (A) a specific amide alcohol and (B) at least one surfactant selected from an anionic surfactant, a nonionic surfactant, and an amphoteric surfactant, wherein the pH (25 DEG C.) of the 20-fold diluted aqueous solution of the composition is 4.5 to 6.8.

Description

technical field [0001] The present invention relates to a detergent composition such as a detergent for shampoos, body washes, face washes, hand washes and dish washes. Background technique [0002] Hitherto, detergents used for shampoos, body washes, etc. to rinse off after being applied to the skin or hair are mainly composed of detergent bases such as alkyl sulfates, polyoxyalkylene alkyl ether sulfates, and the like. However, an amide such as monoethanolamide or diethanolamide is also used to improve the sudsing performance of the detergent since the use of this detergent base alone results in poor sudsing performance. [0003] However, since monoethanolamide is solid at normal temperature, there are operational problems in production. In addition to this, there is another problem such as crystal precipitation during storage at low temperature. On the other hand, there are concerns about the potential of nitroamines from the use of diethanolamide. [0004] In general,...
