<p>Pharmaceutical or cosmetic composition forming a microemulsion comprising at least one active ingredient; a lipophilic phase consisting of a mixture of glycerides and fatty acid esters; a surfactant (SA); a cosurfactant (CoSA); a hydrophilic phase. The composition is characterized in that the lipophilic phase consists of a mixture of C8-C10 polyglycolyzed glycerides, having a hydrophilic-lipophilic balance (HLB) of less than 16, the lipophilic phase being from 30 to 75 % of the total weight of the composition. The invention is characterized in that the surfactant (S) is selected from the group comprising saturated C8-C10 polyglycolyzed glycerides and the polyglycerol oleic esters, the surfactant having an HLB of less than 16. The invention is also characterized in that the cosurfactant (CoS) is selected from the group comprising propylene glycol lauric esters, polyglycerol oleic esters and diglycol ethyl; in that the S/CoS ratio is from 0.5 to 6; and in that the hydrophilic phase of the final micro-emulsion is achieved after ingestion by the physiological liquid of the digestive medium.</p> |
