Abstract
The present invention relates to a sensory emulsifying composition, in particular for cosmetic use, capable of obtaining a liquid oil-in-water-type emulsion comprising at least one cyclodextrin in the form of solid particles, said particles having a volumetric average particle size d(4,3), measured by laser granulometry, of between 2 and 20 μm, preferably between 3 and 12 μm, and more preferably between 4 and 8 μm, and at least one emulsifier of natural origin selected from water-in-oil emulsifiers, having a hydrophilic-lipophilic balance (HLB) of less than 8.
