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.

1-214. (canceled)
A polyurethane dispersion comprising:
- a pre-polymer derived from an algal oil polyol;
- wherein the algal oil polyol is prepared by ring opening an epoxidized algal triglyceride (TAG) oil in the presence of an alcohol,
- wherein the algal TAG oil comprises at least 60% of one or more monounsaturated fatty acids;
- and
- an additive;
- wherein the additive is present in an amount of about 25% weight by weight (w/w) of the polyurethane dispersion;
- and
- wherein the polyurethane dispersion has a bio-based content of at least 50% w/w of the polyurethane dispersion.
A polyurethane dispersion comprising:
- a pre-polymer derived from an algal oil polyol;
- wherein the pre-polymer is an isocyanate-terminated pre-polymer dispersed in water and a chain extender, and
- wherein the algal oil polyol is prepared by ring opening an epoxidized algal triglyceride (TAG) oil in the presence of an alcohol,
- wherein the TAG oil comprises at least 60% of one or more monounsaturated fatty acids;
- and
- an additive;
- wherein the additive is present in an amount of at least about 25% weight by weight (w/w) of the polyurethane dispersion;
- and
- wherein the polyurethane dispersion has a bio-based content of at least 50% w/w of the polyurethane dispersion.
