Ingredient review
Glyceryl Triacetyl Ricinoleate
INCI: Glyceryl Triacetyl Ricinoleate
A lightweight, castor oil-derived emollient that provides a silky feel and shine without clogging pores.
In plain English
Glyceryl Triacetyl Ricinoleate is a modified version of castor oil. It is used in cosmetics to make products feel smooth and silky on the skin or lips, and it helps other ingredients spread evenly. Unlike plain castor oil, it is less sticky and leaves a more elegant, non-greasy finish.

Quick decision guide
Useful, but context matters
Glyceryl Triacetyl Ricinoleate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Glyceryl Triacetyl Ricinoleate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic ester made by reacting castor oil-derived ricinoleic acid with glycerin and then adding acetyl groups. This chemical modification reduces stickiness and improves spreadability compared to natural castor oil.
How it works
It sits on the surface of the skin or hair, filling in rough spots and creating a smooth, even film. This reduces friction, improves slip, and gives a soft, conditioned feel. In lip products, it adds shine and helps pigments glide on evenly.
Pros
Lightweight feel
Unlike many oils, it absorbs quickly and leaves a silky, non-sticky finish, making it ideal for oily or combination skin.
Versatile in formulas
Works well in both water-based and oil-based products, improving texture and application in lipsticks, foundations, and creams.
Cons and cautions
Semi-synthetic origin
It is chemically modified from castor oil, so it may not suit consumers seeking 100% natural or unprocessed ingredients.
Limited research
Most safety data comes from industry studies; independent long-term research on skin absorption is not widely available.
Best for
- Anyone looking for a lightweight, non-greasy emollient
- People with oily or combination skin who want moisture without heaviness
Use caution if
- Those strictly avoiding any semi-synthetic or chemically modified ingredients
Usage tips
Safety summary
Glyceryl Triacetyl Ricinoleate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. As with any ingredient, patch test if you have sensitive skin.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel and the EU SCCS support its use. Studies show it is not a significant irritant or sensitizer. However, independent clinical data on long-term skin effects are limited.
Common label clues
- Typical concentration
- 1% to 10% in leave-on products; up to 50% in lip products
- Regulatory status
- Approved for use in cosmetics by the U.S. FDA and the EU CosIng database. The Cosmetic Ingredient Review (CIR) panel has deemed it safe as used in cosmetics.
- Common uses
- Lipsticks, Lip balms, Foundations, Moisturizers, Hair conditioners
- Environmental note
- Derived from castor oil, a renewable plant source. The chemical modification process involves acetylation, which has a moderate environmental footprint compared to fully synthetic alternatives.
Good to know
- It is often used as a replacement for castor oil in formulas where less stickiness is desired.
- The acetyl modification makes it more resistant to oxidation than plain castor oil.
