DESCRIPTION

Vegetable Oil Phytosterol Esters occur as a light yellow, thick liquid to waxy solid at room temperature and become fully liquid at elevated temperatures. Liquid Vegetable Oil Phytosterol Esters are more viscous than vegetable oils. They are obtained by esterification of free vegetable oil sterols with fatty acids obtained from vegetable oils or fats. (Vegetable oil sterols are commercially obtained by various processes, including vacuum distillation of vegetable oils or fats such as those recovered from deodorizer distillates.) They are freely soluble in edible oils, in chloroform, and in methylene chloride; partly soluble in alcohol, in acetone, in ethyl acetate, and in hexane; and insoluble in water.
