Description

EXAMPLE 1

[0058]

TABLE-US-00001 % by weight Hydrogen peroxide 12.5 Sucrose 50.0 Phosphoric acid q.s. to pH 3.0 Water to 100

[0059] The above composition was mixed with an alkaline composition at a weight ratio of 1 to 2 prior to application onto hair streaks. The resulting composition had a pH of 9.9±0.1.

[0060] The alkaline composition is as follows:

TABLE-US-00002 % by weight Ammonia 10.5 Cetetearyl alcohol 10.0 Sodium cetearyl sulphate 4.0 Water to 100

[0061] The mixture was applied onto level 3 hair streak and left on the hair for 30 min at 40° C. and rinsed off from the streak with water and streak was shampooed once and dried with a drier. The streak colour intensity (L value) was measured with a laboratory colorimeter. It was observed that the streak treated with the above inventive composition was bleached at a much higher extent than hair streak bleached with comparative composition not comprising sucrose (replaced with water).

[0062] The following results were observed

TABLE-US-00003 L value Inventive composition 13.99 Comparative composition 9.51
