Abstract: The invention relates to new liquid and readily pumpable o/w emulsifiers containing a1) alkyl and/or alkenyl oligoglycosides, a2) fatty acid N-alkyl polyhydroxyalkylamides and/or a3) acyl glutamates and b) polyol polyhydroxystearates, with the proviso that the ratio by weight of a) to b) is in the range from 90:10 to 10:90.

Abstract: A process for thickening a water-in-oil and oil-in-water emulsion involving adding to the emulsion a thickening agent consisting of an alkyl or alkenyl oligoglucoside ester formed by esterifying an alkyl or alkenyl oligoglycoside corresponding to formula I:R.sup.1 O--?G!.sub.p (I)wherein R.sup.1 is an alkyl or alkenyl oligoglucoside containing from about 4 to about 22 carbon atoms, G is a sugar unit containing from 5 to 6 carbon atoms, and p is a number having a value of from 1 to about 10, with a fatty acid corresponding to formula II:R.sup.2 CO--OH (II)wherein R.sup.2 CO is an aliphatic acyl radical containing from about 6 to about 22 carbon atoms, and up to about 3 double bonds.
