Abstract: A microemulsion with a mean particle diameter of 5-20 nm includes 5-50% by weight of at least one alkyl and/or alkenyl oligoglycoside carboxylic acid salt corresponding to formula (I): R1O[G]pO[(CH2)mCOO?X+]n (I) wherein R1 is an alkyl and/or alkenyl group containing 4-22 carbon atoms, G is a sugar unit containing 5 or 6 carbon atoms, p is a number of 1-10, m is a number of 1-5, n is a number of 1-5 and X represents alkali metal, alkaline earth metal, ammonium, alkanolammonium, alkyl ammonium or glucammonium; 5-50% by weight of an oil component; and 0-15% by weight of mono- and/or polyhydric alcohols containing 1-4 carbon atoms, and an article or formulation containing the microemulsion are provided.

Abstract: The invention relates to an emulsifier combination which is free from ethoxylated emulsifiers, contains less than 20% by weight water and comprises C8-14 alkyl oligoglycoside, polyol polyhydroxystearate and C6-22 acyl glutamate. The emulsifier is suitable for the production of nanoemulsions by conventional cold/cold or hot/hot processes. The invention also relates to a process for the production of the emulsifier combination and to wipes coated with the nanoemulsions.
