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 a cleansing foaming composition constituting a topical emulsion, which contains a specific surfactant system and an antibacterial or anti-seborrhea active agent, and has good physical stability up to at least 45°C. The present invention also relates to this The composition is used in cosmetics or dermatology, especially for cleaning or treating fatty skin and / or acne-prone skin. [0002] For facial care, cleansing the skin is very important. This cleansing should be as effective as possible, because oily residues, such as excess sebum, household cosmetics residues and cosmetics, especially "waterproof" products, accumulate in the folds of the skin and can block the skin's pores and cause spots. [0003] Fatty skin and / or acne-prone skin requires proper washing to completely remove sebum, clean the surface of the skin and purify the deep pores. Fatty or high seborrhea skin is characterized by thick, shiny skin, occasionally ha...
