Abstract (en)

Solid surfactant mixtures are based on fatty acid polyhydroxyamides (I), derived from 8-32 carbon (un)saturated fatty acids, and other nonionic surfactant(s) and/or other anionic surfactant(s). Solid surfactant mixtures are based on fatty acid polyhydroxyamides of formula (I), derived from 7-31 carbon (un)saturated fatty acids, and other nonionic surfactant(s) and/or other anionic surfactant(s): R = 7-31 carbon (C) alkyl or alkenyl; Z = a polyhydroxyhydrocarbyl group with NOTLESS 2 hydroxyl (OH) groups, which may also be alkoxylated; R<1> = 1-8 C alkyl or a group of formula -(CH2)xNR<2>R<3> pr R<4>O(CH2)n-; R<2>, R<3> = 1-4 C alkyl or 2-4 C hydroxyalkyl; R<4> = 1-4 C alkyl; x = 1-10; n = 2-4.
