Ingredient review
Tetrahydrofurfuryl Ricinoleate
INCI: Tetrahydrofurfuryl Ricinoleate
A gentle, non-greasy emollient that softens skin and improves product texture, with a low risk of irritation or clogged pores.
In plain English
Tetrahydrofurfuryl Ricinoleate is a lab-made ingredient derived from castor oil. It works like a lightweight moisturizer, helping skin feel smooth and soft without leaving a heavy or sticky residue. You'll often find it in lotions, lip balms, and makeup removers because it spreads easily and helps other ingredients glide on.

Quick decision guide
Useful, but context matters
Tetrahydrofurfuryl 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 Tetrahydrofurfuryl 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 by combining tetrahydrofurfuryl alcohol (a solvent) with ricinoleic acid (a fatty acid from castor oil). It acts as an emollient and skin conditioner.
How it works
It sits on the skin's surface, filling in tiny gaps between skin cells to create a smooth, soft feel. It also reduces water loss by forming a light barrier, which helps maintain hydration without feeling heavy.
Pros
Lightweight feel
Unlike heavy oils, this ingredient absorbs quickly and leaves skin feeling smooth without a greasy film, making it ideal for daytime use.
Low irritation potential
It has a low irritation and comedogenic rating, so it's generally safe for sensitive or acne-prone skin types.
Cons and cautions
Limited evidence
While safe based on current data, there are fewer peer-reviewed studies on this specific ester compared to more common emollients like glycerin or squalane.
Not for deep dryness
Its lightweight nature means it may not provide enough moisture for very dry or flaky skin, which often needs richer occlusives like shea butter.
Best for
- People with oily or combination skin who want light moisture
- Anyone looking for a non-comedogenic emollient in lotions or makeup removers
Use caution if
- Those with extremely dry or compromised skin barriers may prefer richer oils or butters
Usage tips
Safety summary
Tetrahydrofurfuryl Ricinoleate is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in regulatory reviews. However, long-term human studies are limited.
Research notes
Available safety data comes primarily from industry and regulatory assessments (e.g., CosIng, CIR). No major clinical studies on efficacy exist, but its function as an emollient is well understood through chemical properties.
Common label clues
- Typical concentration
- Typically 1% to 10% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) as a skin-conditioning agent. No known restrictions at typical use levels.
- Common uses
- Moisturizers, Lip products, Makeup removers, Hair conditioners
- Environmental note
- As a semi-synthetic ingredient, its environmental impact is lower than some petrochemical-based esters, but it is not biodegradable in all conditions.
Good to know
- It is often used in 'silky' or 'velvety' texture claims on product labels.
- Despite being derived from castor oil, it is processed synthetically, so it's not considered a natural ingredient.
