1. An emulsifying composition, capable of obtaining a liquid oil-in-water-type emulsion comprising:
a) 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,
b) and at least one emulsifier of natural origin selected from water-in-oil-type emulsifiers, having a hydrophilic-lipophilic balance of less than 8.
