A sunscreen composition for ultraviolet radiation is reported, characterized in that it comprises: particulate metal oxide inorganic particles composed of zinc oxide, titanium oxide and their mixtures, the inorganic particles are coated with poly[C 8 -C 20 hydroxyl groups Carboxylic acid], the Zeta potential of the coated particles ranged from 2 to 10 mV measured over 1 min in dodecane at a loading of 10%, poly[C 8 -C 20 hydroxycarboxylic acid] with The relative weight ratio of the inorganic particles is 1:100 to 1:10. |
