ABSTRACT:
Anti-acne preparations include finely divided, dispersed particles of benzoyl peroxide and finely divided, dispersed particles of salicylic acid in an aqueous gel formed from carboxy vinyl polymer resins. The gels are prepared without loss of salicylic acid by fully hydrating the resin in an aqueous medium and allowing the resin to gel in the absence of an alkaline neutralizing agent.
