Ingredient review
PEG-20 Glyceryl Ricinoleate
INCI: PEG-20 Glyceryl Ricinoleate
A gentle emulsifier that helps mix oil and water in cleansers and creams, but may be drying for very sensitive skin in high concentrations.
In plain English
PEG-20 Glyceryl Ricinoleate is a helper ingredient that allows oil and water to blend together in products like cleansers and lotions. It is made from castor oil and a synthetic compound called PEG (polyethylene glycol). In simple terms, it keeps your product from separating and helps it spread smoothly on your skin. While generally considered safe, some people with very sensitive skin might find it slightly drying if used in high amounts.

Quick decision guide
Useful, but context matters
PEG-20 Glyceryl 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 PEG-20 Glyceryl 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
PEG-20 Glyceryl Ricinoleate is a semi-synthetic emulsifier created by reacting castor oil with ethylene oxide (PEG). It belongs to the glyceryl ricinoleate family and is commonly used in cosmetics to stabilize oil-in-water emulsions.
How it works
It works by reducing the surface tension between oil and water molecules, allowing them to mix into a stable, uniform cream or lotion. This helps the product feel smooth and spread easily on the skin or hair.
Pros
Effective emulsifier
Helps oil and water blend seamlessly, giving your product a smooth, uniform texture that feels nice on the skin.
Low irritation potential
Generally well-tolerated by most skin types, including normal and combination skin, with a low risk of irritation or clogging pores.
Cons and cautions
Potential for mild dryness
In high concentrations or for very sensitive skin, it may strip natural oils slightly, leading to a tight or dry feeling.
Synthetic origin
Made with PEG (polyethylene glycol), which is processed synthetically. Some consumers prefer to avoid PEGs due to manufacturing concerns.
Best for
- People who use standard moisturizers and cleansers
- Those looking for a stable, well-formulated product
Use caution if
- Individuals with known sensitivity to PEG compounds
- Those seeking 100% natural or PEG-free formulations
Usage tips
Safety summary
PEG-20 Glyceryl Ricinoleate is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential, though very sensitive skin may experience mild dryness. Regulatory bodies like the CIR (Cosmetic Ingredient Review) have deemed it safe as used.
Research notes
Research on PEG-20 Glyceryl Ricinoleate is limited but consistent with other PEG emulsifiers. Studies show it is well-tolerated and effective as an emulsifier. No significant safety concerns have been raised in peer-reviewed literature.
Common label clues
- Typical concentration
- 0.5% to 5% in rinse-off products; lower in leave-on products
- Regulatory status
- Approved for use in cosmetics by the FDA (USA) and the European Commission, with concentration limits typically under 5% in leave-on products.
- Common uses
- Cleansers, Moisturizers, Makeup removers, Hair conditioners
- Environmental note
- PEG compounds are generally biodegradable, but their production involves ethylene oxide, which has environmental concerns. Some brands avoid PEGs for this reason.
Good to know
- PEG-20 Glyceryl Ricinoleate is considered safe by major regulatory bodies when used as directed.
- It is not the same as pure castor oil—it has been chemically modified to act as an emulsifier.
