ABSTRACT:
A process for the manufacture of new crystalline salts of N-[2-(dimethylamino)ethyl]-1,2-dithiolane-3-pentanamide (racemic and chiral forms) is described. Such salts are stable, crystalline and have very good solubility in water. The salts exhibit antioxidant properties. They inhibit collagenase and elastase enzymes. They have excellent anti acne activity in addition tyrosinase inhibition. They are, by themselves and in combination with other known agents, important cosmetic ingredients.
