Claim:
1. A composition comprising from 0.1 to 50% by weight, in relation to the total weight of the composition, titanium dioxide and/or zinc oxide and at least one water soluble copolymer comprising: (a) 5.06 to 10.93% by weight of at least one acrylic acid monomer and/or one methacrylic acid monomer and/or their salt(s), (b) 89.07 to 93.97% by weight of at least one monomer of formula (I): wherein: R represents methacrylate, R′ designates hydrogen, X represents a structure with n unit(s) of ethylene oxide (“EO”) and m unit(s) of propylene oxide (“PO”), arranged regularly or randomly, m and n are 2 integers comprised between 0 and 100, at least one of which is non-zero, wherein said water soluble copolymer has a molecular mass ranging from 62,000 and 11,025,000 g/mol as determined by GPC; wherein said composition has a higher UV absorbency value at wavelengths between 290 and 400 nm, compared to an otherwise identical sunscreen or cosmetic having a same amount of pigment particles that does not contain said water-soluble copolymer; and wherein said composition is in a physiological or cosmetically acceptable form.
