Abstract

The invention relates to a gel composition for treating acne, which comprises the following components in percentage by weight: 0.01 to 20 percent of at least of a retinoic acid active component, 0.01 to 20 percent of diphenylperoxyanhydride, 0.1 to 10 percent of at least one high polymer gel and 0.1 to 4 percent of antioxygen, wherein the antioxygen may be one or more of butylated hydroxytoluene (BHT), ethylenediaminetetraacetic acid-2 (EDTA-2), Na, butylated hydroxyanisole (BHA), vitamin E, vitamin E acetate and vitamin E nicotinate. The composite antioxygen used in the invention can effectively solve the chemical and physical stability problems of retinoic acid and diphenylperoxyanhydride composite preparation, and it is found that the antioxygen has good chemical and physical stabilizing effect on common gel systems, greatly improves the gel selection range, recues cost, simplifies operation steps and effectively controls product quality.

Description

technical field [0001] The invention relates to an aqueous gel for treating acne containing retinoic acid and benzoyl peroxide and a related method for preparing the aqueous gel. Background technique [0002] Acne, also known as acne, pimples or acne, folliculitis, is a skin disease caused by blockage and inflammation of hair follicles and sebaceous glands. It is very common to use retinoic acid alone to treat acne. Epidermal keratinocytes, melanocytes and dermal fibroblasts are all important target cells for the action of retinoic acid. Benzoyl peroxide is also one of the most widely used drugs for treating acne. The mechanism of action of benzoyl peroxide is not completely clear, but it is believed that it is mainly due to its bactericidal ability to Propionibacterium acnes. Formyl-treated patients showed decreased lipids and free fatty acids and mild desquamation with reduced comedones and acne lesions. Retinoic acid or benzoyl peroxide is usually combined with clindamy...
