The present invention relates to a composition and use of polymeric
urethane esters quats as an active ingredient for skin and hair
contacting personal care compositions and products related thereto. These
compositions are generally produced by the reaction of a trialkanolamine
with a hydroxy fatty acid to produce a trialkanolamine fatty acid ester,
which is then polymerized with a diisocyanate and in preferred
embodiments, further reacted with a quaternizing agent to produce
preferred quaternized compositions according to the present invention.
