Abstract
Improved water soluble abradant skin cleanser is provided comprising in a non-oleaginous hydrous cream base a sparingly soluble relatively soft non-toxic non-irritating particulate salt, a non-irritating, non-toxic surfactant as a stable cream base, employing at least one derivative of sulfuric acid, e.g. sulfate ester salt or sulfonate and water. In a preferred embodiment, borax is combined with a substantial amount of an alkyleneoxy sulfate ester salt or tauride salt and a small amount of water. The cleanser aids in the treatment of oily skin, acne and scalp conditions.
Claims12
An abradant skin cleansing cream consisting essentially of:
- from 20 to 80 weight percent of a slightly water soluble, non-toxic physiologically acceptable inorganic salt of a size in the range of about 20 to 200 mesh having a hardness greater than 1 Moh, said inorganic salt being a sodium or potassium tetraborate or a sodium or potassium pentaborate;
- and from 80 to 20 weight percent respectively of a cream composition comprising from about 15 to 70 weight percent of a sodium salt of an anionic foaming agent based on a sulfuric acid anion;
- and
- an amount of water from 5 to 65 weight percent of said cream composition and substantially less than the amount required to dissolve said inorganic salt at ambient temperature.
An abradant skin cleansing cream composition comprising:
- from 20 to 80 weight percent of borax of a particulate size in the range of about 20 to 200 mesh and from 80 to 20 weight percent respectively of a cream base composition comprising:
- from 15 to 70 weight percent of a sodium salt of a foaming anionic surfactant;
- from 5 to 65 weight percent of water as initially added;
- up to 12 total weight percent of at least one polyol, polyol ester or polyol ether nonionic surfactant.
An abradant skin cleansing cream composition having from 35 to 60 weight percent of borax of an average particle size in the range of about 125 to 750.mu. and from 40 to 65 weight percent of a cream base composition comprising from about 10 to 50 weight percent of a sodium tauride anionic foaming agent;
- from about 3 to 12 weight percent of a polyol fatty acid ester nonionic surfactant;
- and from about 40 to 60 weight percent water.
An abradant skin cleansing cream composition comprising from about 35 to 60 weight percent of borax having an average particle size in the range of about 125 to 750.mu. and from 40 to 65 weight percent of a base cream composition comprising from about 30 to 60 weight percent of sodium polyalkyleneoxy sulfate ester anionic foaming agents;
- from about 3 to 12 weight percent of a polyol fatty acid ester;
- and from about 30 to 60 weight percent of water.
