Abstract: Anti-UV cosmetic compositions in the form of an emulsion may include an emulsifying polymer which is prepared by polymerizing an anionic monomer and a C1-C7 ester of an unsaturated carboxylic acid. Such anti-UV cosmetic compositions may be prepared in the absence of a surfactant. The preparation and use of such anti-UV cosmetic compositions may provide anti-UV cosmetic composition having dual protection for the skin: protection against UV rays and limiting the penetration of UV filters into the skin.

Abstract: A method may prepare a tinted cosmetic composition, in particular a make-up composition, which is particularly versatile. Such a method may make it possible to prepare tinted cosmetic compositions that can be suitable for many types of skin tone, e.g., including preparing a continuous hydrophilic phase comprising (i) a hydrophilic compound A in a range of from 90 to 99.6 wt. % of a hydrophilic phase of the oil-in-water emulsion, and (ii) a polymer P, in a range of from 0.4 to 10 wt. % of the hydrophilic phase, the polymer P comprising, in polymerized form, an anionic monomer (a1) and a C1-C8 ester (a2); adding, under stirring, a lipophilic phase comprising a lipophilic compound B, to form a dispersion of lipophilic phase particles in the continuous hydrophilic phase; then adding, under stirring, of a pigment C. The coloration, retention, and stability properties of such compositions are particularly improved.
