  • Patent number: 4832949
    Abstract: A depliatory composition for removal of hair from the human skin is made up of a mixture of honey, sugar and citric acid which mixture is heated to a predetermined temperature level, then allowed to cool so as to form a highly viscous, wax-like composition which can be applied manually in slender strips to the skin. The composition will firmly adhere to the hair with which it comes into contact and, by quickly drawing away from the skin, will cause the hair to be removed from its root but without causing undue irritation and swelling.
