An emulsion hair bleach composition prepared by combining an aqueous oxidizing agent composition, a persulfate composition, and, optionally, a bleach oil composition, in amounts sufficient to provide a mixture containing an active oxygen concentration of about 3 to 5% by weight of the total mixture, a total alkalinity concentration of about 0.7&#x2013;1.2 meq/gm., and 0.5&#x2013;20% by weight of the total mixture of an oil having a solubility parameter of 5&#x2013;12 (cal/cm); an emulsion hair bleach composition capable of lightening hair in 10 to 30 minutes, and a kit for use in bleaching hair.

Method and compositions for bleaching hair

An emulsion hair bleach composition prepared by combining an aqueous oxidizing agent composition, a persulfate composition, and, optionally, a bleach oil composition, in amounts sufficient to provide a mixture containing an active oxygen concentration of about 3 to 5% by weight of the total mixture, a total alkalinity concentration of about 0.7-1.2 meq/gm., and 0.5-20% by weight of the total mixture of an oil having a solubility parameter of 5-12 (cal/cm ) ; an emulsion hair bleach composition capable of lightening hair in 10 to 30 minutes, and a kit for use in bleaching hair.

An aqueous hair color composition for oxidatively coloring hair in twelve minutes or less, wherein said composition is prepared by combining a dye mixture and a developer mixture, said aqueous hair color composition comprising 0.01-2.0% (combined weight) of the total composition of primary intermediates and couplers, a free alkalinity concentration of 0.20-0.75 meq/gram, and a hydrogen peroxide concentration of 4-6% by weight of the total composition; and a hair coloring kit containing separate containers of an aqueous dye mixture and an aqueous developing mixture for use with said dye mixture.
