SYNONYMS Propane-1,2-diol esters of fatty acids, INS No. 477
DEFINITION Propylene glycol esters of fatty acids are mixtures of propylene glycol mono- and diesters of saturated and unsaturated fatty acids derived
from edible oils and fats. The products are produced either by direct esterification of propylene glycol with fatty acids or by transesterification
of propylene glycol with oils or fats. When prepared by transesterification, the product may contain residual mono- and diglycerides and glycerol. The process may be followed by molecular distillation to separate the monoesters.
Assay Not less than 85% total fatty acid esters
DESCRIPTION White or cream coloured solids of waxy appearance, plastic products or viscous liquids
FUNCTIONAL USES Emulsifier
