New compositions based on alkylpolyglycosides and fatty alcohols, in particular for the preparation of stable fluid emulsions

摘要

Compositions comprising 5-60 wt. % of a mixture of alkyl polyglycosides and 40-95 wt. % of one or more fatty alcohols are new. The compositions comprise: (a) 5-60 wt. % of a mixture of alkyl polyglycosides of formula (I): and (b) 40-95 wt. % of one or more alcohols of formula (II): R = linear or branched aliphatic groups containing y carbon atoms; y = 12, 14, 16, 18, 20 or 22; G = saccharide residues; x = 1-5; where the mixture comprises 10-25 wt. % of (I;y=12), 10-30 wt. % of (I; y=14), 0-10 wt. % of (I; y=16) + (I; y=18), and 40-80 wt. % of (I; y=20) + (I; y=22); R' = 12-22C linear or branched aliphatic groups, preferably R. An Independent claim is also included for stable fluid emulsions comprising at least one aqueous phase, an oil phase and a composition as above as emulsifier.
