Use Of Special N-Alkyl-N-Acylglucamines For Conditioning Hair In Hair Washing Agents

摘要

The invention relates to N-alkyl-N-acylglucamines of formula (I), which exhibit in hair-washing agents comprising an aqueous surfactant system with at least one anionic surfactant, a hair-conditioning effect, wherein, in formula (I), Ra is a linear or branched, saturated or unsaturated C5-C21 alkyl radical and Rb represents a C1-C4 alkyl radical, and wherein the N-alkyl-N-acylglucamines (I) contain at least 8 wt. %, based on the total amount of N-alkyl-N-acylglucamines (I), of compounds with a saturated C16-, C18- or a mono- or polyunsaturated C18 fatty acid radical Ra—CO—.;

1. A method for conditioning hair, comprising the step of contacting the hair with a hairwash composition comprising at least one N-alkyl-N-acylglucamine of the formula (I) and at least one aqueous surfactant system, wherein the at least one aqueous surfactant system comprises at least one alkyl sulfate and/or one alkyl ether sulfate as anionic surfactant, where in the formula (I) Ra is a linear or branched, saturated or unsaturated C5-C21 alkyl radical and Rb is a C1-C4 alkyl radical, and wherein the at least one N-alkyl-N-acylglucamine according to formula (I) comprises at least 8 wt %, based on the total amount of the at least one N-alkyl-N-acylglucamine, of a saturated C16, C18, or singly or multiply unsaturated C18 fatty acid radical Ra—CO—.
