Abstract
A foaming cleansing composition includes 2.5% to 12.0% Benzoyl Peroxide, at least one acrylate polymer, Hyaluronic Acid, Niacinamide, a combination of anionic and amphoteric surfactants, expressly excluding alkyl polyglucosides, and water. The composition provides a unique textural feel as compared with existing benzoyl peroxide containing products, and in particular, is formulated as a light mousse-type architecture with viscosity which is retained on skin upon application and resists dripping, even in the shower. The composition is shelf stable and stable on application, demonstrating a viscosity of about 18-25 UD (Viscosity Rheomat M3 Spindle), and a pH about 5.5 to about 6.5.
Claims12
A foaming cleansing composition, comprising:
- a. about 9% to about 12% benzoyl peroxide, by weight based on the total weight of the foaming cleansing composition;
- b. about 0.1% to about 5.0% at least one acrylate polymer, by weight based on the total weight of the foaming cleansing composition;
- c. about 0.1% to about 2.0% hyaluronic acid, by weight based on the total weight of the foaming cleansing composition;
- d. about 0.1% to about 2.0% niacinamide, by weight based on the total weight of the foaming cleansing composition;
- e. about 4% to about 15% a combination of anionic and amphoteric surfactants, expressly excluding alkyl polyglucosides, by weight based on the total weight of the foaming cleansing composition;
- and
- f. water,
- wherein the composition has a stable mousse form including a pH from about 5.5 to about 6.5 and a viscosity of about 85,000-100,000 cP for at least six weeks at a temperature of 25° C.
A foaming cleansing composition, comprising:
- a. about 10.0% benzoyl peroxide;
- b. at least one acrylate polymer, the acrylate polymer comprising acrylates/C10-30 alkyl acrylate crosspolymer present from about 0.1% to about 5.0%;
- c. from about 0.1% to about 2.0% hyaluronic acid;
- d. from about 0.1% to about 2.0% niacinamide;
- e. from about 4.0% to about 15.0% a combination of anionic and amphoteric surfactants including cocamidopropyl hydroxysultaine and sodium C14-16 olefin sulfonate and expressly excluding alkyl polyglucosides;
- f. water;
- and
- g. at least one additional compound selected from the group consisting of pH adjusters, chelating agents, alcohols, antimicrobials, preservatives, vitamins, fragrances, humectants, emulsifiers, and combinations thereof,
- all amounts by weight, based on the weight of the composition, wherein the composition has a mousse form, a pH from about 5.5 to about 6.5, and a viscosity of about 85,000-100,000 cP.
