Ingredient review
PEG-15 Glyceryl Ricinoleate
INCI: PEG-15 Glyceryl Ricinoleate
A gentle emulsifier that helps mix water and oil in products, generally well-tolerated but may be drying for very sensitive skin.
In plain English
PEG-15 Glyceryl Ricinoleate is a helper ingredient that allows water and oil to blend together smoothly in creams, lotions, and cleansers. It is made by attaching a chain of 15 polyethylene glycol (PEG) units to a molecule derived from castor oil. This process makes the ingredient water-friendly while keeping its oil-loving properties, so it can stabilize formulas and help them spread easily on the skin. It is considered low risk for irritation and clogging pores, but some people with very reactive skin may find it slightly drying over time.

Quick decision guide
Useful, but context matters
PEG-15 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-15 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
A semi-synthetic emulsifier created by reacting castor oil with ethylene oxide to add 15 PEG units. It belongs to the glyceryl ricinoleate family and is used to reduce surface tension between oil and water phases in cosmetic products.
How it works
It works by positioning itself at the boundary between oil and water droplets, lowering the interfacial tension so the two phases mix into a stable emulsion. This prevents separation and gives products a smooth, uniform texture. It also helps other ingredients spread evenly across the skin.
Pros
Effective emulsifier
Helps water and oil mix into a stable, smooth product so you don't get separation or a gritty texture.
Low irritation potential
Rated low for both irritation and comedogenicity, making it suitable for most skin types including acne-prone skin.
Cons and cautions
Potential for dryness
In very sensitive or compromised skin, PEG compounds can strip natural oils over time, leading to tightness or flaking.
Manufacturing impurities
If not properly purified, PEG ingredients may contain trace contaminants like 1,4-dioxane, though reputable brands ensure purity.
Best for
- People with normal to combination skin looking for lightweight moisturizers
- Those who prefer non-greasy, well-blended cleansers and makeup removers
Use caution if
- Individuals with very dry or damaged skin who may experience mild drying from PEG-based emulsifiers
Usage tips
Safety summary
PEG-15 Glyceryl Ricinoleate is considered safe for cosmetic use at typical concentrations. The main safety concern is potential contamination with 1,4-dioxane during manufacturing, but reputable suppliers and brands test for purity. It has low irritation and comedogenic ratings, making it a gentle option for most skin types.
Research notes
Research on PEG-15 Glyceryl Ricinoleate specifically is limited, but the broader class of PEG emulsifiers has been reviewed by the Cosmetic Ingredient Review panel, which concluded they are safe for use in cosmetics when formulated to avoid impurities. Studies show low acute toxicity and minimal skin irritation in patch tests.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database. The Cosmetic Ingredient Review (CIR) panel has evaluated PEG compounds and found them safe when formulated to meet purity standards.
- Common uses
- Cleansers, Lotions, Creams, Makeup removers
- Environmental note
- PEG compounds are generally biodegradable, but their production involves ethylene oxide, which is energy-intensive. Some environmental groups recommend choosing PEG-free alternatives if you prefer minimal processing.
Good to know
- PEG-15 Glyceryl Ricinoleate is often found in micellar waters and oil cleansers because it helps lift makeup and sunscreen without harsh scrubbing.
- The number '15' refers to the average number of PEG units, which affects how water-loving or oil-loving the molecule is.
