23443-472 ABSTRACT An emulsifier system for the preparation of oil-in- water emulsions of ethereal oils is disclosed. The system comprises alkyl polyglycosides of the formula I R-O-Z (I) wherein R represents a straight-chain or branched, saturated or unsaturated alkyl radical having 8 to 16 C atoms, Z represents an oligoglycoside radical and n is on average 1 to 5. The system may further comprise small amounts of conventional co- emulsifiers. The alkyl polyglycosides of formula I show an excellent skin and mucosa tolerance, combined with high emulsifiability for oils and fat phases, as well as a low toxicity and outstanding biodegradability. The oil-in-water emulsions of ethereal oils, on their own or in admixture with a fat phase, are used in cosmetics and medicine.
