Abstract:
What is provided herein is a method for preparing a product which comprises discrete microdroplets of an oil in water stabilized by in situ polymerization of a water-soluble vinyl monomer. The method comprises dispersing the oil in water, optionally with a surfactant, adding the water-soluble vinyl monomer, preferably vinylpyrrolidone, optionally with a comonomer, and polymerizing the monomer or comonomers in situ such that the oil is stabilized in the resulting polymer solution as discrete microdroplets. The product is used in conditioning hair care compositions and hair and skin care compositions, including those containing a water-soluble acryl comonomer.

Abstract:
Procédé de préparation d'un produit comprenant des microgouttelettes discrètes d'une émulsion aqueuse stabilisée par polymérisation in situ d'un monomère vinylique soluble dans l'eau. Le procédé consiste à disperser l'huile dans l'eau, facultativement à l'aide d'un tensio-actif, à ajouter le monomère vinylique soluble dans l'eau, de préférence un vinylpyrrolydone, facultativement à l'aide d'un comonomère, et à polymériser le monomère ou les comonomères in situ de manière que l'huile est stabilisée dans la solution polymère résultante sous forme de microgouttelettes discrètes. On utilise le produit dans des compositions de conditionnement capillaire et dans des compositions de soins capillaires et cutanés, entre autres celles contenant un comonomère d'acryle soluble dans l'eau.
