Abstract
The use of hydrogen peroxide produced in enzymatic oxidation has been investigated for oxidative hair dyeing and permanent waving.For enzymatic oxidations were used pyruvate oxidase, lactate oxidase, glycerol oxidase, xantine oxidase, uricase and pyranose oxidase.Successful dyeing of goat hair was carried out using uricase and pyranose oxidase in a commercial hair dyeing formulation with p-phenylenediamine.An uricase produced the maximum hydrogen peroxide concentration up to about 0.06% after 5min. of reaction at pH 7.0.Effect of enzyme on hair waving was estimated according to Kirby method.Results on waving efficiency and wave retention ratio showed that permanent waving with uricase is almost on the level of chemical method with sodium bromide.
