Sun protection compositions against ultraviolet radiation are reported, which have micronized inorganic metal oxide particles, selected from zinc oxide, titanium oxide and their mixtures, in which the inorganic particles are coated with (poly)C8-C20 hydroxycarboxylic acid, the coated particles measured at 10% charge in dodecane and elapsed time of one minute have Zeta Potential that varies from 2 to 10 mv and the amounts between the (poly)C8-C20 hydroxycarboxylic acid and the inorganic particles are in ratio in relative weight from 1:100 to 1:10. |
