Abstract
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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
123 words
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.
Claim 2
Dependent Claim
