Abstract
The present invention pertains to a process for refining soap-containing crude polyol fatty-acid polyester reaction product, comprising the step of contacting the crude reaction product with an aqueous acid solution to substantially convert the soap into its corresponding free fatty acids, the subsequent step of drying said crude reaction product to substantially remove any free-water therein, and the step of substantially removing from the dried crude reaction product any salts therein.
