Ingredient review
Cetyl Acetyl Ricinoleate
INCI: Cetyl Acetyl Ricinoleate
A gentle, plant-derived emollient that softens and smooths skin without clogging pores.
In plain English
Cetyl Acetyl Ricinoleate is a semi-synthetic ingredient made from castor oil and cetyl alcohol. It works by forming a thin, non-greasy film on the skin that helps lock in moisture and leaves the skin feeling soft and smooth. Because it is lightweight and non-comedogenic, it is often used in lip products and moisturizers for sensitive or acne-prone skin.

Quick decision guide
Useful, but context matters
Cetyl Acetyl 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 Cetyl Acetyl 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
Cetyl Acetyl Ricinoleate is an ester derived from ricinoleic acid (from castor oil) and cetyl alcohol (from coconut or palm oil). It is a clear to pale yellow liquid that acts as an emollient and skin conditioner.
How it works
It spreads easily on the skin, creating a protective barrier that reduces water loss (transepidermal water loss, or TEWL) and improves the feel of the product. It also helps other ingredients penetrate more effectively.
Pros
Gentle on skin
Cetyl Acetyl Ricinoleate has a low irritation risk, making it suitable for sensitive skin types and for use around the delicate eye and lip areas.
Non-comedogenic
It does not clog pores, so it is a good choice for people with oily or acne-prone skin who still want the benefits of an emollient.
Cons and cautions
Semi-synthetic origin
While derived from natural sources, it undergoes chemical processing, which may not appeal to those seeking 100% natural or unprocessed ingredients.
Potential sustainability issues
The cetyl alcohol component is often sourced from palm oil, which can be associated with deforestation and habitat loss unless certified sustainable.
Best for
- People with dry or dehydrated skin looking for lightweight moisture
- Those with sensitive or acne-prone skin who need a non-comedogenic emollient
Use caution if
- Individuals with a known allergy to castor oil or cetyl alcohol derivatives
Usage tips
Safety summary
Cetyl Acetyl Ricinoleate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in regulatory reviews.
Research notes
While not extensively studied on its own, the ingredient is a derivative of ricinoleic acid and cetyl alcohol, both of which have well-established safety profiles. It is widely used in cosmetics with a long history of safe use.
Common label clues
