Title
(EN) WATER-IN-OIL EMULSION HAVING A HIGH INTERNAL WATER PHASE CONTENT
(FR) EMULSION EAU DANS HUILE À HAUTE TENEUR EN PHASE INTERNE AQUEUSE
Abstract
(EN) The present application relates to a composition in the form of a water-in-oil emulsion having a high internal water phase content and improved stability and improved sensory qualities, comprising: a) a continuous oil phase containing at least two emulsifiers chosen from esters of C8-C30 fatty acid and polyglycerol, and at least one non-silicone oil with a relative density to water at 4°C of less than 0.9; and b) an aqueous phase dispersed in the oil phase and constituting a content of at least 70 wt % of the total weight of the composition constituting 100%; characterised in that the ratio by weight of the emulsifiers to the at least one oil is less than 1/5.
(FR) La présente demande se rapporte à une composition sous forme d'émulsion eau-danshuile à haute teneur en phase interne aqueuse, de stabilité et sensorialité améliorées, comprenant : a) une phase continue huileuse contenant au moins deux émulsifiants, choisis parmi les esters d'acide gras en C8-C30 et de polyglycérol, et au moins une huile non siliconée de densité relative à l'eau à 4°C inférieure à 0,9; et b) une phase aqueuse dispersée dans ladite phase huileuse, et représentant une teneur d'au moins 70% en poids, sur le poids total de la composition représentant 100%; caractérisée en ce que le ratio en poids desdits émulsifiants sur ladite au moins une huile est inférieur à 1/5.
