    • The invention relates to a cosmetic composition, in particular for photoprotecting the skin and/or the hair, in the form of a dispersion comprising two immiscible phases stabilized with at least one anionic surfactant chosen from the salts of fatty acids and of monovalent or polyvalent metals, of ammonium or of organic bases, a compound for screening out ultraviolet radiation, which can be adsorbed at the interface of the said immiscible phases, derived from benzylidenecamphor and comprising at least one partially or totally neutralized sulphonic acid function, a metal oxide nanopigment coated with hydrophobic hydrocarbon-based coating agents and a cationic or zwitterionic amphiphilic compound which leads, with the anionic surfactant, to the formation of a compound capable of lowering the water/liquid paraffin interface tension at 40° C. by more than 14 mN.m−1 for an anionic surfactant concentration of 0.1 mmol/100 g, by more than 26 mN.m−1 for an anionic surfactant concentration of 0.5 mmol/100 g and by more than 33 mN.m−1 for an anionic surfactant concentration of 1 mmol/100 g.
    • 本发明涉及一种化妆品组合物,特别是以分散体的形式对皮肤和/或头发进行光保护的化妆品组合物,所述分散体包含两种不混溶相,所述两种不混溶相用至少一种选自脂肪酸的盐和一价或多价金属的阴离子表面活性剂稳定化 铵或有机碱,用于筛选紫外线辐射的化合物,其可以吸附在衍生自亚苄基樟脑的所述不混溶相的界面处,并且包含至少一种部分或全部中和的磺酸官能团,金属氧化物纳米颜料涂覆 具有疏水性烃基涂层剂和阳离子或两性离子两亲化合物,其与阴离子表面活性剂一起形成能够在40℃下降低大于14mN.m的水/液体石蜡界面张力的化合物。 -1,对于阴离子表面活性剂浓度为0,阴离子表面活性剂浓度为0.1mmol / 100g,超过26mN.m-1 0.5mmol / 100g,超过33mN.m-1,阴离子表面活性剂浓度为1mmol / 100g。
