Propylene Glycol Dicaprylate/Dicaprate
What is it?
Propylene Glycol Isostearate, Propylene Glycol Laurate, Propylene Glycol Myristate, Propylene Glycol Oleate and Propylene Glycol Oleate SE are monoesters of propylene glycol and fatty acids. SE indicates that it is a self-emulsifying form that contains some sodium and/or potassium oleate.
Propylene Glycol Dicaprylate, Propylene Glycol Dicaprylate/Dicaprate, Propylene Glycol Dicocoate, Propylene Glycol Dipelargonate, Propylene Glycol Oleate, Propylene Glycol Dicaprate, Propylene Glycol Diisostearate and Propylene Glycol Dilaurate are diesters of proplyene glycol and fatty acids. The use of the "/" in the name indicates that the ingredient is a mixture of Propylene Glycol Dicaprylate and Propylene Glycol Dicaprate.
In cosmetics and personal care products, Propylene Glycol monoesters and diesters are used in the formulation of moisturizers, cleansing products, fragrance products, and makeup products such as foundations and lipsticks.

Safety Information
The Food and Drug Administration (FDA) includes propylene glycol mono- and diesters of fats and fatty acids on its list of multipurpose additives for direct addition to food. The FDA also permits the use of propylene glycol mono- and diesters of fats and fatty acids as indirect food additives for use as components of coatings in contact with food.
The safety of Propylene Glycol esters and diesters has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that Propylene Glycol Dicaprylate, Propylene Glycol Dicaprylate/Dicaprate, Propylene Glycol Dicocoate, Propylene Glycol Dipelargonate, Propylene Glycol Isostearate, Propylene Glycol Laurate, Propylene Glycol Myristate, Propylene Glycol Oleate, Propylene Glycol Oleate SE, Propylene Glycol Dioleate, Propylene Glycol Dicaprate, Propylene Glycol Diisostearate and Propylene Glycol Dilaurate were safe as cosmetic ingredients.
