The use of a haloalkynyl derivative, especially iodo-3-propynyl-2-butylcarbamate, as a stabilizer for ultrafine oil-in-water emulsions used for cosmetic compositions and impregnated skin cleansing towelettes

Use of a haloalkynyl derivative as a stabilizer for an oil-in-water emulsion cosmetic or dermatological composition with average oil globule size 50-1000 nm and the composition itself for topical application comprising an oily phase dispersed in water the haloalkynyl derivative and having a viscosity at 25 deg C of 1-20 mPa.s. Independent claims are included for: (1) a method of treating the skin including the scalp, the hair, eyebrows, nails and/or the lips by applying the composition; (2) a method of preparing the composition by producing a classic emulsion at a temperature within or above the phase inversion domain or heating to it, refrigerating and adding the haloalkynyl derivative and additional components which are unstable at the phase inversion temperature; (3) an article comprising a water insoluble substrate and the composition added to it or impregnated into it; and (4) a cosmetic procedure of care, cleansing and/or makeup removal from the skin by wiping with the article. La présente invention a trait à une composition cosmétique et/ ou dermatologique sous forme d'émulsion huile-dans-eau ultrafine, dans laquelle la taille moyenne des globules d'huile va de 50 nm à 1000 nm, caractérisée par le fait qu'elle contient de l'iodo-3 propynyl-2 butylcarbamate. Les compositions selon l'invention sont susceptibles d'être obtenues selon la technique d'émulsification par inversion de phase (PIT). L'iodo-3 propynyl-2 butylcarbamate permet d'obtenir des émulsions ultrafines particulièrement stables. Les compositions de l'invention peuvent être utilisées dans de nombreuses applications cosmétiques et dermatologiques. Elles peuvent être également utilisées pour imprégner un support et constituer une lingette.
