Abstract
The application relates to an emulsifying composition, in particular for cosmetic use, allowing an oil-in-water emulsion (O/W) to be obtained, the emulsion comprising at least one cyclodextrin and at least one O/W emulsifier of natural origin with a hydrophilic-lipophilic balance value (HLB) of more than 8. The O/W emulsifier of natural origin can be selected from alkyl polyglucosides, mixtures of at least one alkyl polyglucoside and at least one fatty alcohol, and non-ethoxylated polyol fatty esters. The application also relates to a composition of the Pickering emulsion type, in particular for cosmetic use, containing the emulsifying composition according to the invention, and to the process for preparing such a composition of the O/W Pickering emulsion type, in particular at low temperatures.
