Polyethylene glycol propylene glycol cocoates or PEG propylene glycol cocoates are chemical compounds produced by the esterification of polyoxyalkyl alcohols with fatty acids from coconut oil (primarily lauric acid).[1] Their chemical designation is PEG-8,[2] referring to its polyethylene glycol (PEG) molecular chain length.

Uses

[edit]

PEG propylene glycol cocoates are used in cosmetics and toothpaste to form emulsions, which they do by reducing surface tension in the substances of which an emulsified form is required.
