Abstract
Provided herein are surface treating compositions for imparting beneficial surface properties to substrates. The compositions can be prepared by reacting a bio-based polyol with an isocyanate and an ionogenic molecule. The compositions can be used to treat a variety of substrates to provide enhanced properties to a surface of the substrate. Also provided are methods for the chemical modification of triglycerides and fatty acids and use thereof in creating beneficial surface treating compositions.
