Ingredient review
Glyceryl Diricinoleate
INCI: GLYCERYL DIRICINOLEATE
A gentle, plant-based emollient that softens skin and improves product feel without clogging pores.
In plain English
Glyceryl diricinoleate is a fatty ingredient made from castor oil and glycerin. It works by coating the skin with a thin, non-greasy film that locks in moisture and leaves skin feeling smooth. Unlike heavier oils, it absorbs quickly and is unlikely to cause breakouts, making it a good choice for sensitive or acne-prone skin.

Quick decision guide
Useful, but context matters
Glyceryl Diricinoleate 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 Diricinoleate.
- 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
Glyceryl diricinoleate is an ester formed from glycerin and ricinoleic acid, a fatty acid derived from castor oil. It is a clear to pale yellow liquid that acts as an emollient and skin-conditioning agent in cosmetics.
How it works
It spreads easily over the skin, forming a protective layer that reduces water loss (transepidermal water loss, or TEWL) and helps other ingredients absorb better. Its molecular structure also gives products a silky, non-sticky feel.
Pros
Gentle on skin
Glyceryl diricinoleate has a low irritation and comedogenic rating, making it suitable for sensitive and acne-prone skin types.
Improves product feel
It gives creams and lotions a silky, non-greasy texture that spreads easily and absorbs quickly, enhancing the user experience.
Cons and cautions
Limited research
While safe based on current data, there are fewer peer-reviewed studies on this specific ester compared to more common emollients like squalane or jojoba oil.
Potential heaviness for oily skin
In high concentrations, some users with very oily skin may find it slightly heavier than lighter alternatives like dimethicone.
Best for
- People with dry or dehydrated skin looking for lightweight moisture
- Those with sensitive or acne-prone skin who want a non-comedogenic emollient
Use caution if
- Individuals with a known allergy to castor oil derivatives
