Abstract
Abstract Hair removal compositions useful for cosmetic, medical and other purposes comprise 90 to 99.5% corn syrup and 0.5% to 10% added water by weight. The compositions can also include additives such as germicides, preservatives and opacifiers. The compositions are used by applying them to the surface of the skin in a hairy area, pressing a sheet of paper or other fibrous material against the area and subsequently lifting the sheet of fibrous material or peeling it off the skin surface. The compositions are also useful in removing blemishes and scaly, flaky or dry skin.

A method of removing body hair, comprising the steps of: (A) applying as a coating to a hairy area a depilatory composition consisting of (i) about 90% to 99.5% by weight of the composition consisting of a corn syrup mixture composed of a plurality of different saccharides having a viscosity of about 700,000 cps at about 80° F. and a dextrose equivalent in a range from about 40 to 44, said corn syrup mixture having an overall solids content in the range from about 75% to 95% by weight, and a water balance content in a range from about 25% to 5% by weight, (ii) about 10%-0.5% by weight of the composition consisting of added distilled/deionized water, (iii) a germicidally effective amount of imidazolidinyl urea, (iv) an effective preservative amount of an alkyl p-hydroxybenzoate, and (v) an effective opacifying amount of styrene polyvinyl pyrrolidone; (B) pressing a fibrous material sheet against the composition-coated hairy area to enmesh hair in the coating; and (C) lifting the sheet away from the hairy area with the hair from the hairy area embedded in the coating.
