9 Claims. (Cl. 167-811) This invention relates to the treatment of hair as in the permanent waving thereof.

An object of this invention is to provide an improved process for waving the hair and chemicals for use in waving the hair.

A further object of this invention is to provide a hair waving method and chemicals for use in hair waving which produce curls which retain a tight uniform helical shape on drying and which maintains its improved shape after repeated washings or other treatments which normally weaken curl structure.

In the waving of hair, it is common practice to soften or treat the hair with a reducing solution such as a solution of thioglycolic acid and ammonium hydroxide in water which produces changes in the hair by reducing keratin and which softens the hair to permit shaping of the hair on a mandrel such as a curling rod or the like. An oxidizing agent is applied to the treated hair to neutralize that portion of the reducing agent which remains on the hair and to oxidize the reduced keratin to restore the strength thereof, but the strength is only partially restored upon treatment with the oxidizing agent. According to our improved method, we add a water-soluble, non-toxic salt of a polyvalent metal such as magneisum sulfate, aluminum sulfate, calcium acetate, calcium chlo ride, or the like to an aqueous solution of oxidizing agent. Alternatively, we employ an aqueous solution of an oxidizing salt of a polyvalent metal such as magnesium brornate, calcium brornate, aluminum brornate or the corresponding iodates or mixtures thereof in neutralizing and treating reduced keratin of the hair. The hair fibres of waves neutralized with our improved compositions have a substantially greater tensile strength than hair fibres neutralized with conventional oxidizing solutions, and the waves are longer lasting and have a lesser tendency for fibres to separate from one another.

Oxidizing agents with which our salts can be used include water-soluble ammonium, alkali and alkaline earth bromates, iodates, and periodates, hydrogen peroxide, and urea peroxide and the like.

Mixtures of the oxidizing agent and polyvalent salt can be made to form a mixture which can be dissolved in water, and in such a mixture, the oxidizing agent and polyvalent salt can be mixed in approximately the ratio desired in the neutralizing solution. An example of such a mixture contains 100 parts of sodium brornate and 280 parts of MgSO -7H O, all parts being by weight. In the neutralizer solution, it is preferred to have substantially as great a concentration of polyvalent salt as can be maintained in solution conveniently in order to obtain the maximum effect from the polyvalent salt, but lesser concentrations can be used if desired.

The following examples are given to illustrate the invention in greater detail, but it is to be understood that the examples are given primarily by way of example, rather than by Way of limitation, except as set forth in the claims. In the following examples and in the remainder hereof, all parts or percentages are given by weight.

Example I A tress of hair including approximately 12 fibres of human hair was wrapped around a quater-inch mandrel in helical fashion, for three complete revolutions and held in place thereon. The tress was immersed in a reductant solution containing 7.0% thioglycolic acid and suflicient ammonia to provide an excess and give a pH of 9.4. The tress was immersed in the reductant for approximately 7 minutes and was then rinsed thoroughly in tepid water. The tress was then immersed in a neutralizer solution which contained parts of sodium bromate, 280 parts of MgSO -7H O, 3 parts of sodium lauryl ether sulfate together with sufiicient sulfuric acid to bring the composition to a pH of 6.0 and sufficient water to make 1,000 parts of neutralizer solution. The tress was immersed in the neutralizer for 7 minutes. The tress was then rinsed in tepid water and removed from the mandrel. On drying in air, the tress retained its uniform helical shape with very little change in diameter and the individual fibres showed no tendency to lose their helical shape or separatefrom one another. On immersion in water, the tress exhibited practically no motion at all, neither expanding into a large helix nor contracting into a tight knotted configuration.

Example II A tress of hair including approximately 12 fibres of human hair was wrapped around a quarter-inch mandrel in helical fashion, for three complete revolutions and held in place thereon. The tress was immersed in a reductant solution containing 7.0% thioglycolic acid and sufiicient ammonia to provide an excess and give a pH of 9.4. The tress was immersed in the reductant for approximately 7 minutes and was then rinsed thoroughly in tepid water. The tress was then immersed in a neutralizer solution which contained 100 parts of sodium brornate, parts of Ca(C H O -H O, 3 parts of sodium lauryl ether sulfate, sufficient sulfuric acid to bring the composition to a pH of 6.0 and sufficient water to make 1,000 parts of neutralizer. The tress was immersed in the neutralizer for 7 minutes. The tress was then rinsed in tepid water and removed from the mandrel. On drying in air, the tress retained its uniform helical shape with very little change in diameter and the individual fibres showed no tendency to lose their helical shape or separate from one another.

Example III A tress of hair including approximately 12 fibres of human hair was wrapped around a quarter-inch mandrel in helical fashion, for three complete revolutions and held 7 minutes and was then rinsed thoroughly in tepid water.

The tress was then immersed in a neutralizer solution. In the preparation of the neutralizer, 100 parts of sodium bromate, parts of boric acid and 3 parts of sodium alkyl phenoxyether sulfonate were dissolved in 882 parts of water to form a first solution. 38 parts of were dissolved in 62 parts of the first solution, and the resultant neutralizer solution was used at once. The tress was immersed in the neutralizer solution for 7 minutes. The tress was then rinsed in tepid water and removed from the mandrel. On drying in air, the tress retained its uniform helical shape with very little change in diameter and the individual fibres showed no tendency to lose their helical shape or separate from one another.

Example IV A tress of hair including approximately 12 fibres of human hair was wrapped around a quarter-inch mandrel in helical fashion, for three complete revolutions and held in place thereon. The tress was immersed in a reductant solution containing 7.0% thioglycolic acid and sufficient ammonia to provide an excess and give a pH of 9.4. The tress was immersed in the reductant for approximately 7 minutes and was then rinsed thoroughly in tepid water. The tress was then immersed in a neutralizer solution which contained parts of sodium periodate, 200 parts of MgSO -7H O and sufiicient water to make 1,000 parts of neutralizer. The tress was immersed in the neutralizer for 7 minutes. The tress was then rinsed in tepid water and removed from the mandrel. On drying in air, the tress retained its uniform helical shape with very little change in diameter and the individual fibres showed no tendency to lose their helical shape or separate from one another.

Example V A tress of hair including approximately 12 fibres of human hair was wrapped around a quarter-inch mandrel in helical fashion, for three complete revolutions and held in place thereon. The tress was immersed in a reducta-nt solution containing 7.0% thioglycolic acid and sufiicient ammonia to provide an excess and give a pH of 9.4, The tress was immersed in the reductant for approximately 7 minutes and was then rinsed thoroughly in tepid water. The tress was then immersed in a neutralizer solution which contained 20 parts of sodium periodate, 300 parts of MgSO -7H O and sufficient water to make 1,000 parts of neutralizer. The tress was immersed in the neutralizer for 7 minutes. The tress was then rinsed in tepid water and removed from the mandrel. On drying in air, the tress retained its uniform helical shape with very little change in diameter and the individual fibres showed no tendency to lose their helical shape or separate from one another.

Example VI A tress of hair including approximately 12 fibres of human hair was wrapped around a quarter-inch mandrel in helical fashion, for three complete revolutions and held in place thereon. The tress was immersed in la reductant solution containing 7.0% thioglycolic acid and sufiicient ammonia to provide an excess and give a pH of 9.4. The tress was immersed in the reductant for approximately 7 minutes and was then rinsed thoroughly in tepid water. The tress was then immersed in a neutralizer solution which contained 250 parts of commercial 6% hydrogen peroxide solution in water, 200 parts of Ca (CzHgOz 2 H20 and sufficient water to make 1,000 parts of neutralizer. The tress was immersed in the neutralizer for 7 minutes. The tress was then rinsed in tepid water and removed from the mandrel. On drying in air, the tress retained its uniform helical shape with very little change in diameter and the individual fibres showed no tendency to lose their helical shape or separate from one another.
