Abstract
Abstract Hair and skin treating compositions containing hydrolyzed proteins having an average molecular weight in the range of from 500 to 2,000 are enhanced with an approximately equimolar quantity of amino acid derived zwitterion having a molecular weight less than 200, such as taurine. Preferably the taurine is present in such a composition in the range of from 1 to 5% by weight, and the composition has a pH in the range of from 3 to 10, the most preferably from 3 to 7.
