Abstract
A compound that is a polyether of a saturated monobasic secondary hydroxyl fatty acid, preferably 12-hydroxy stearate, or a reaction product of the polyether with a polyhydric alcohol, a capping agent or a combination of both. Prepare the compound by contacting a saturated hydroxy monobasic fatty acid or derivative thereof with an alkoxide in the presence of a double metal cyanide catalyst such that a polyether of the fatty acid is formed. Optionally, preparation also includes a step of capping the polyether, or alternatively, contacting the polyether with a polyhydric alcohol.
