Abstract: This invention relates to storage oil-in-water emulsions, hereinafter referred to as 0/w emulsions, containing alkyl glucosides and a partial glyceride with a monoglyceride content of 60-95% by weight and to emulsifier concentrates containing alkyl glucosides, a partial glyceride with a monoglyceride content of 60 to 95% by weight and a long-chain alcohol.

Abstract: Alkyl and/or alkenyl oligoglycosides can be obtained in short reaction times and high yields by a process in which glycose is reacted with fatty alcohols at elevated temperature in the presence of sulfomonocarboxylic acids containing 2 to 8 carbon atoms, carboxylic anhydrides thereof and/or mixed cyclic sulfonic/carboxylic anhydrides thereof as acidic catalysts, the water of reaction is removed and the reaction products are worked up.

Abstract: This invention relates to alkyl and/or alkenyl oligoglycoside isethionates prepared by reacting salts of vinyl sulfonic acid at an elevated temperature and in the presence of basic compounds, with alkyl and/or alkenyl oligoglycosides of the formula (1): R.sup.1 O--(G).sub.p in which R.sup.1 is a straight-chain or branched-chain aliphatic hydrocarbon group with 6 to 22 carbon atoms and 0, 1,2 or 3 double bonds, G is a glycose unit with 5 or 6 carbon atoms, and p is a number between 1 and 10. The products exhibit marked surface-active characteristics and are useful as surfactants.
