Captex 100
CAS Number: 53824-77-4         EINECS Number: 258-814-9          Chemical Name: Propylene Glycol Dicaprate

Synonyms:
Propylene didecanoate

Product Description:
Captex 100 is a diester formed from selected high-purity vegetable fatty acids and propylene glycol and is
Kosher certified. Captex 100 is totally miscible in mineral oil and in 95% ethanol. In addition, it has a
lower viscosity than mineral oil. Captex 100 is an excellent skin emollient and produces a smooth, non-
greasy, powdery after-feel with shine. Due to its excellent solvency, Captex 100 works exceptionally well
as a substitute for mineral oil in cosmetic makeup-remover formulas. Because of its unique properties, vis-
cosity and miscibility with other cosmetic components, Captex 100 offers advantages in suncare and hair-
care products where spreadability and shine are desired. The non-oily character, excellent stability, bland
taste and neutral odor make this product an ideal choice as a solubilizer and carrier of vitamins, colors and
flavors for selected pharmaceutical and nutritional formulations or processing aids such as pan and mold-
release agents.
