Description

technical field [0001] This application claims priority to US Provisional Application Serial No. 61 / 048,706, filed April 29, 2008, which is incorporated herein by reference. technical field [0002] The present invention relates to compositions and methods for bleaching hair. In particular, the present invention relates to stabilized hair bleaching products comprising persulfates and oleaginous gels. Background technique [0003] Hair bleaching is a well known treatment in the field of hair cosmetics. Hair bleaching involves the application of an oxidizing agent to the hair for a period of time effective to obtain the desired lighter hair color. The oxidizing agent is usually a hydrogen peroxide solution with a concentration of 6 to 12% by weight. Hydrogen peroxide is applied to the hair at an alkaline pH and gradually lightens the hair color by oxidizing the melanin that provides the color. [0004] In order to increase the lightening efficiency of peroxide solutions,...
