Abstract
The present patent application relates to a foaming composition for topical application, containing (1) a surfactant system such that at least one paracrystalline phase of direct or cubic hexagonal type appears when the temperature increases above 30 DEG C. and such that this paracrystalline phase remain present up to at least 45 DEG C., and (2) an active agent chosen from antibiotics and anti-seborrhoeic agents. The surfactant system which allows such a paracrystalline phase to be obtained preferably comprises at least one water-soluble surfactant and at least one water-insoluble surfactant. It preferably comprises at least one water-soluble soap. These compositions exist in the form of creams with good physical stability at ambient temperature and even up to at least 45 DEG C. They may be used n cosmetics or dermatology, for cleansing or treating greasy skin and / or acne-prone skin.
Description
technical field [0001] The present invention relates to cleansing foaming compositions constituting creams for topical application, containing specific surfactant systems and antibacterial or anti-seborrhea active agents, and having good physical stability up to at least 45° C., and also to such Cosmetic or dermatological use of the composition, in particular for cleansing or treating oily and / or acne-prone skin. [0002] For facials, it is important to cleanse the skin. This cleansing should be as effective as possible because greasy residues such as excess sebum, makeup residue and cosmetics, especially "waterproof" products, accumulate in the skin's folds and can clog the skin's pores and cause blemishes. [0003] Oily and / or acne-prone skin requires proper cleansing to completely remove sebum, cleanse the skin's surface and purify the depths of the pores. Fatty or hyperseborrhea skin is characterized by thick, shiny skin, occasionally with an oily appearance, with dilate...
