(FR) COMPOSITION ÉMULSIONNANTE CONSTITUÉE D'UN ÉMULSIONNANT HUILE-DANS-EAU ET D'UNE CYCLODEXTRINE DE GRANULOMÉTRIE SÉLECTIONNÉE, APTE À FOURNIR UNE ÉMULSION HUILE-DANS-EAU AVEC EFFETS SENSORIELS AMÉLIORÉS, À USAGE COSMÉTIQUE
Abstract
(EN)
The present invention relates to a sensory emulsifying composition, in particular for cosmetic use, capable of making it possible to obtain an oil-in-water-type emulsion, comprising at least one cyclodextrin in the form of solid particles, said particles having a volume-average 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 oil-in-water emulsifiers, having an HLB greater than or equal to 8, and most preferably greater than or equal to 9.
