Propylene Glycol Dicaprylate ●
TL;DR. This ingredient is an emollient ester used to add slip, reduce greasiness, improve spread, and help dissolve oil-soluble ingredients in creams, lotions, sunscreens, and color cosmetics.
What does Propylene Glycol Dicaprylate do in a cosmetic formula?
This ingredient is an emollient ester used to add slip, reduce greasiness, improve spread, and help dissolve oil-soluble ingredients in creams, lotions, sunscreens, and color cosmetics.
Is Propylene Glycol Dicaprylate clean?
It is generally considered low-irritation and low-allergen in normal cosmetic use. Clean-beauty friction is mostly about its synthetic ester identity and possible petrochemical feedstock, not a major restricted-list profile.
Is Propylene Glycol Dicaprylate sustainable?
This material is commonly made from a fatty acid fraction that can be plant-derived plus a diol that may be petroleum-derived or bio-based. It is expected to be more biodegradable than silicone oils, but sourcing transparency matters because the fatty portion can be tied to palm or coconut supply chains.
Is Propylene Glycol Dicaprylate COSMOS-approved?
It is not a straightforward fit for COSMOS-organic positioning, and COSMOS-natural acceptance depends on feedstock origin and whether the esterification route meets the standard’s rules for chemically processed agro-ingredients. From a Green Chemistry lens, it scores better when made from renewable inputs with simple esterification and good biodegradability, and less well when reliant on petrochemical feedstock.
How does Propylene Glycol Dicaprylate work chemically?
The molecule is a nonionic diester made from a three-carbon diol and two saturated C8 fatty chains, giving it a lightweight, oily, low-polarity profile with good spreading and pigment-wetting behavior. It is typically used in the low single digits to about 10% in emulsions or anhydrous systems, is broadly stable near normal skin-care pH, and can hydrolyze under strongly acidic or alkaline conditions.
