Ingredient review
Octyldodecyl Ricinoleate
INCI: OCTYLDODECYL RICINOLEATE
A gentle, non-greasy emollient that softens skin and improves product texture without clogging pores.
In plain English
Octyldodecyl Ricinoleate is an ingredient made by combining a fatty alcohol (octyldodecanol) with ricinoleic acid, which comes from castor oil. In skincare, it acts as an emollient, meaning it helps soften and smooth the skin by filling in the tiny gaps between skin cells. It also gives products a silky, non-sticky feel and can help other ingredients spread more easily. Because it's not greasy and has a low risk of clogging pores, it's often used in moisturizers, lip balms, and makeup removers.

Quick decision guide
Useful, but context matters
Octyldodecyl 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 Octyldodecyl 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 created from octyldodecanol (a fatty alcohol) and ricinoleic acid (a fatty acid from castor oil). It appears as a clear to slightly yellow liquid oil.
How it works
It sits on the skin's surface, forming a thin, breathable film that reduces water loss and makes the skin feel softer. Its molecular structure also helps it mix well with other oils and ingredients, improving the overall texture and spreadability of a product.
Pros
Lightweight emollience
Provides softness and smoothness without a heavy, greasy residue, making it comfortable for daily use on the face and body.
Low pore-clogging risk
Rated low on the comedogenic scale, so it's less likely to cause breakouts compared to heavier oils like coconut oil.
Cons and cautions
Semi-synthetic origin
While derived from natural castor oil, it undergoes chemical processing, which may not align with a '100% natural' skincare philosophy.
Potential heaviness for oily skin
In very high concentrations (above 10%), it might feel slightly heavy on already oily or acne-prone skin types.
Best for
- People with dry or normal skin looking for a lightweight emollient
- Those who prefer non-comedogenic moisturizing ingredients
Use caution if
- Individuals with a known allergy to castor oil derivatives (rare)
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. Low irritation and sensitization potential based on industry safety assessments.
Research notes
Limited direct clinical studies, but ricinoleic acid derivatives have a long history of safe use in personal care. The Cosmetic Ingredient Review (CIR) panel has reviewed similar esters and found them safe.
Common label clues
- Typical concentration
- 1% to 10% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. No known restrictions at typical use levels.
- Common uses
- Moisturizers, Lip products, Makeup removers, Hair conditioners
- Environmental note
- Castor oil is a renewable plant source, but the esterification process requires energy and chemical inputs. Biodegradability is expected to be moderate.
Good to know
- It is often used as a replacement for mineral oil in 'natural' formulations.
- The name 'ricinoleate' comes from ricinoleic acid, the main fatty acid in castor oil.
