A skin- or hair-care composition containing silica additionally comprises a C.sub.2-4 alkyl ester of a di, tri- or tetrabasic carboxylic acid or hydroxy-carboxylic acid (optionally acetylated). The alkyl ester may be dissolved in an aqueous solvent system.
A cholesterol ester clathrate comprising a cholesterol ester included within a hydroxyalkylated cyclodextrin; a hydrous composition comprising a hydroxyalkylated cyclodextrin, a cholesterol ester and water; a hydrous composition comprising a hydroxyalkylated cyclodextrin, a cholesterol ester, a hydrous stabilizer, and water; a hydrous composition comprising a hydroxyalkylated cyclodextrin, a cholesterol ester, a clay mineral, and water; a cosmetic containing a hydrous composition; and processes for making the cholesterol ester clathrate and various hydrous compositions. The cholesterol ester clathrate exhibits an emulsifying effect and the hydrous compositions are excellent in water-holding capacity, hydration properties, and separation stability at a high temperature.
A cholesterol ester clathrate comprising a cholesterol ester included in a hydroxyalkylated cyclodextrin; a hydrous composition comprising a hydroxyalkylated cyclodextrin, a cholesterol ester and water; a hydrous composition comprising a hydroxyalkylated cyclodextrin, a cholesterol ester, a hydrous stabilizer, and water; a hydrous composition comprising a hydroxyalkylated cyclodextrin, a cholesterol ester, a clay mineral, and water; cosmetics containing these hydrous compositions; and process for the preparation thereof. The clathrate exhibits an emulsifying effect in itself. Further, the hydrous compositions are excellent in water-holding capacity and are improved in hydration properties and separation stability at a high temperature.
The present invention relates to a method for treating spots and other symptoms of acne and related skins disorders in mammals, which comprises applying to the affected area of the skin of the mammal a non-aqueous composition comprising a dermatologically effective amount of a particulate silica, silica hydrate or precursor thereof. The invention also provides compositions for topical application to the skin which comprise particulate silica, silica hydrate or a precursor thereof in a non-aquous carrier medium.
A process of bleaching fabrics is disclosed where a liquid or pasty composition comprising acetyl triethyl citrate and a source of hydrogen peroxide is applied to fabrics before they are immersed in an aqueous wash liquor.
The invention deals with forming stable dispersions or emulsions of hydrated silica which in turn are useful in forming cosmetic compositions such as blends, powders, or sticks useful in treating the hair, skin, or nails.
