A composition for improving effectiveness of dye precursors for change of colour of hair

Abstract

The present disclosure relates to a synergistic compositions for improving effectiveness of dye precursors for change of colour of hair comprising one or more phosphate esters in the ranges of 0.001 to 15 wt % and one or more carboxylic acid esters in the ranges of 0.001 to 15 wt % in a select ratio co-acting with an oxidative dye precursor in combination with oxidising agents in a cosmetically acceptable base, surprisingly imparts superior colour uptake with good grey hair coverage. Further, the present disclosure relates to a composition provided in different cosmetically acceptable forms including cream, shampoo, lotion, gel and foam with significantly reduced dye chemicals. The present disclosure relates to a composition that is safe, efficient, cost-effective, and requires a significantly reduced quantity of dye precursors.
