What Is Glyceryl Triacetyl Ricinoleate?
Glyceryl Triacetyl Ricinoleate is a plant-derived ingredient made from castor oil. Chemists start with ricinoleic acid, the main fatty acid in castor oil, then link it to glycerin and acetic acid to create a smooth liquid ester. This reaction is called esterification and it turns the thick sticky castor oil into a lighter silky material that spreads easily on skin.
The cosmetic world picked up on this ingredient in the mid-1900s when formulators were looking for a gentler alternative to heavy mineral oils. Its ability to soften skin without feeling greasy quickly earned it a spot in color cosmetics and skin care.
Today you will most often see Glyceryl Triacetyl Ricinoleate in lipsticks, lip balms, foundations, moisturizers, hair masks, hand creams and body butters where it helps give formulas a smooth glide and a comforting after-feel.

It is also rapidly absorbed which limits the time it sits on the pore surface. Most users, even those with combination or mildly oily skin, report no increase in breakouts.
Suitable for acne-prone skin in most cases, though extremely reactive skin should still watch for individual triggers.
No official data links the ingredient to fungal acne issues and it is considered safe for use on the lips where pore density is low.
