Title: Improvements in or relating to hair waving compositions containing ammonium thioglycollate
IPC: A01G9/16
Filed: 1949-08-15
Abstract: A hair-waving composition is obtained by emulsifying with water a chlorinated paraffin hydrocarbon, such as a chlorinated paraffin wax, containing at least 13 carbon atoms per molecule, by means of an emulsifying agent, such as sorbitan mono-oleate, which is soluble in oil, and an emulsifying agent, such as a sorbitan mono-oleate polyoxyalkylene derivative, which is soluble in water, and adding ammonium thioglycollate to the mixture in a proportion of 2.5-8.0 per cent by weight of the total weight of the aqueous solution.  A chlorinated paraffin hydrocarbon having 25 carbon atoms and containing 10-70 per cent of chlorine may be used. Normally solid as well as liquid chlorinated paraffin hydrocarbons may be used, provided sufficient oil and emulsifier is present to dissolve the chlorinated paraffin and produce a fluid.  Other water-soluble emulsifying agents, which may be used with the oil-soluble emulsifiers, are aliphatic organic amine soaps such as decylamine oleate, triethanolamine oleate, butylamine oleate, diethyl hexylamine oleate, or amino ethyl ethanolamine oleate, or similar compounds of palmitic or stearic acid.  More stable emulsions may be obtained by incorporating mineral oils, dibutyl sebacate, olive oil, or castor oil.  The pH of the composition is preferably adjusted to a value of 9.0-9.5 by the addition of ammonia.  The composition may contain borax and gelatine as additional dispersing agents.  Lanolin, keratin, and perfumes, may also be present.  The sorbitan mono-oleate polyoxyalkylene compound may be obtained by condensing ethylene oxide with sorbitan mono-oleate in the molecular ratio of 20 : 1.  In making the emulsion, the oily material such as mineral oil, lanolin, or both, and the chlorinated paraffin are mixed together and warmed to 50 DEG  C.  The sorbitan mono-oleate and the sorbitan oleate polyoxyalkylene compound are then added to form an oil base. Gelatine and borax are dissolved in part of the water and the solution is heated to 45 DEG  C.  The oil base is then added.  When the mixture has cooled, the ammonium thioglycollate, dissolved in the remainder of the water, is added.  A decolorizing agent such as sodium hydrosulphite may be added with the final addition of water.ALSO:A composition for use in hair-waving is obtained by emulsifying with water a chlorinated paraffin hydrocarbon, such as a chlorinated paraffin wax, containing at least 13 carbon atoms in the molecule, by means of an emulsifying agent, such as sorbitan mono-oleate, which is soluble in oil, and an emulsifying agent, such as a sorbitan mono-oleate polyoxyalkylene derivative, which is soluble in water, and adding ammonium thioglycollate to the mixture in a proportion of 2.5-8.0 per cent by weight of the total weight of the aqueous solution.
