Abstract
Abstract A composition for dyeing hair comprises an aqueous solution of a hair dye and a compound having the formula R1O(-C2H3O(CH2OH))n H wherein the repeating group is linear, R is a lipophile group and n has a statistical average value greater than 1 and equal to or less than 10. The said compound is also an effective peptizing agent for pulverulent materials such as pigments.
