Abstract
Copper lanolate, a novel product, can be produced by initially preparing an isotropic solution of a sodium or potassium salt of lanolic acid and thereafter precipitating copper lanolate therefrom by the addition thereto of a solution of a copper salt. The resulting copper lanolate is employed in anti-acne compositions for topical application to the skin.
