ABSTRACT:
A process for refining organic-solvent containing crude polyol fatty-acid polyester reaction product, including the steps of distilling the crude reaction product to substantially remove the organic solvent, and subsequently subjecting the distilled reaction product to a bleaching treatment. The process allows an economic use of bleaching agents while achieving good color and color stability of the refined product.
