O / W microemulsions

O/W micro-emulsions contain: (A) an oil phase based on (A1) mono- and/or diesters and/or (A2) fatty acid triglycerides; (B) as emulsifiers (B1) fatty acid N-alkylpolyhydroxyalkylamides and/or (B2) alkyl and/or alkenyl oligoglycosides, as well as (C) partial esters of fatty acids with polyols as co-emulsifiers. These O/W micro-emulsions may be prepared in a two-stage cold preparation process and are characterised by their storage stability, their good environmental compatibility and excellent nourishing properties.
