Topical composition comprising a thickener of acrylic acid-acrylamide water-in-oil emulsion |
摘要 |
A thickener comprises a water-in-oil reverse emulsion and a copolymer having moieties derived (i) from a monounsaturated monocarboxylic acid monomer containing from 3 to 5 carbon atoms, the monocarboxylic acid either being in free form or in the form of an inorganic salt, and (ii) from a monoacrylamide monomer. The copolymer is in solution in the aqueous phase constituting the emulsion, the oil phase of this emulsion consisting of a mixture of at least one volatile oil and at least one non-volatile oil. The weight ratio between the volatile oil and the non-volatile oil is between 90/10 and 10/90. The oil phase represents from 10 to 60% by weight of the whole. Water represents from 30 to 70% by weight of the whole. The copolymer represents from 10 to 30% by weight of the whole and a surfactant represents from 5 to 20% by weight of the whole.
