  • Patent number: 10961484
    Abstract: What are described are compositions comprising a) one or more sugar amines of the formula (I) in which R1 and R2 are independently H, CH3 or 2-hydroxyethyl and/or one or more corresponding protonated sugar amines with the counterion R—COO— in which R is defined as R from the substances of component b) below, and b) one or more substances selected from the group consisting of fatty acids of the formula R—COOH, fatty acid salts of the formula R—COO-M+ and mixtures thereof, in which R is a linear or branched saturated alkyl radical having 11 to 21 carbon atoms or a linear or branched, mono- or polyunsaturated alkenyl radical having 11 to 21 carbon atoms and M+ is a counterion. The compositions described are very advantageous, for example, for production of liquid washing compositions, and of shower gels, liquid soaps or face cleansers. In addition, the sugar amines are advantageously suitable as neutralizing agents for fatty acids.
