Abstract
An emulsion of an oily phase in a surfactant-free gelled aqueous phase containing expanded hollow thermoplastic particles of acrylonitrile polymer or copolymer. The particles ensure the dispersion of the oily phase in the gelled aqueous phase and are preferably particles of expanded copolymers of acrylonitrile and acrylic or styrene-based monomers and/or vinylidene chloride. The emulsion obtained can be employed, for example, for the care or cleansing of skin and/or hair or for use in a skin make-up. It can also form a dermatological product.
Claims25
A surfactant-free emulsion of an oily phase in a gelled aqueous phase, comprising oil, water, at least one gelling agent and expanded hollow thermoplastic particles of an acrylonitrile polymer or an acrylonitrile copolymer.
A method for dispersing, without the use of a surfactant, an oily phase in a gelled aqueous phase, comprising the step of mixing expanded hollow thermoplatic particles of acrylonitrile polymer or copolymer with the aqueous gelled phase and the oily phase.
