Abstract: A process for the preparation of mixtures which comprise mostly sorbitol monoesters, sorbitol diesters and partial glycerides, sorbitol being reacted with triglycerides in the presence of at least one alkaline catalyst, is described, wherein the cocatalyst used for the reaction is:a) a part amount of the product of the above reaction as a self-emulsifier and/orb) an amidoamine of the following formula (I) ##STR1## in which in which: R.sup.1 is an alkyl or alkenyl group having 6 to 13 carbon atoms, R.sup.2 is an alkyl group having 1 to 6 carbon atoms or an H atom, R.sup.3 is an alkyl group having 1 to 6 carbon atoms and n is a number from 1 to 6. The novel process gives purer products and leads to a considerably improved space/time yield.

Abstract: Amidopropyl-N-alkyl-polyhydroxyalkylamines of the following formula (1) ##STR1## in which Z is a linear polyhydroxyhydrocarbon radical having at least 2 free or oxyalkylated hydroxyl groups, R.sup.1 is a C.sub.1 to C.sub.7 -alkyl radical or C.sub.2 to C.sub.4 -hydroxyalkyl radical and COR is an aliphatic acyl radical having 6 to 22 carbon atoms, and salts thereof from an inorganic or organic acid are described. They are prepared by a) reaction of a compound of the formula (2) ##STR2## with acrylonitrile to give the compound of the formula (3) ##STR3## b) hydrogenation of the product obtained in step a) to give the compound of the formula (4) ##STR4## and c) monoacylation of the product obtained in step b) in the melt to give the compound of the formula (1) mentioned. The compounds according to the invention are readily soluble in water and water/alcohol mixtures and are advantageous co-surfactants for use in detergents and cleaning compositions and in cosmetic preparations for cleansing the hair and skin.

Abstract: New saturated fluoroalkylamines and carboxyalkylbetaines and alkylsulfobetaines derived therefrom, and mixtures containing the new fluoroalkylamines and mixtures containing the new fluorobetaines are described. The saturated fluoroalkylamines conform to the formula below ##STR1## in which n is an integer from 3 to 17 and R.sup.1 and R.sup.2 are C.sub.1 to C.sub.4 -alkyl, C.sub.1 to C.sub.4 -hydroxyalkyl or hydrogen, with the proviso that only one of the two substituents R.sup.1 and R.sup.2 is hydrogen. The carboxyalkylbetaines and sulfobetaines and the mixtures thereof are highly effective products for reducing the surface tension of water/air systems and the interfacial tension of water/hydrocarbon systems.
