<p>There is disclosed the preparation of the ester of a tocopherol and certain acids possessing an unsaturated bond in conjugation with the carbonyl group and the use thereof in sunscreen composition. The use of these esters, particularly the p-aminobenzoate of d- alpha -tocopherol, provide a method of reducing the amount of ultraviolet radiation reaching the skin. The esters may be applied to the skin using a carrier which may also contain other skin treating compositions. The preparation may be prepared in the form of solutions, oils, suspensions, gels, emulsions, ointments, pastes or sticks.</p> |
