Polyglyceryl-3 Ricinoleate
INCI: POLYGLYCERYL-3 RICINOLEATE
A mild, plant-derived emulsifier that helps create stable, creamy textures without common irritation.
In plain English
Polyglyceryl-3 Ricinoleate is a helper ingredient that allows water and oil to mix smoothly in your skincare products. It's made from castor oil and glycerin (a natural moisturizer), so it's considered gentle and unlikely to clog pores or cause breakouts. You'll find it in lotions, creams, and cleansers where it helps create a nice, even texture.

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 Polyglyceryl-3 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 combining ricinoleic acid (from castor oil) with polyglycerin-3 (a chain of glycerin molecules). It belongs to the polyglyceryl ester family, known for being milder than traditional emulsifiers.
How it works
It reduces the surface tension between oil and water, allowing them to form a stable mixture (emulsion). This prevents your product from separating into oily and watery layers, and helps deliver both water-soluble and oil-soluble ingredients evenly onto your skin.
Pros
Gentle on skin
Polyglyceryl-3 Ricinoleate has a low irritation profile, making it a good choice for sensitive skin types and daily-use products.
Plant-derived origin
Sourced from castor oil and glycerin, it appeals to those looking for more natural or renewable ingredients in their skincare.
Cons and cautions
Limited to emulsion formulas
This ingredient only works in products that need to mix oil and water, so it won't appear in water-only or oil-only products.
Not for ultra-light gels
If you prefer very lightweight, watery gel textures, this emulsifier may not be the best choice as it tends to create richer creams.
Best for
- Anyone with sensitive or reactive skin looking for gentle formulas
- People who prefer plant-derived, mild emulsifiers in their routine
Use caution if
- Those with a known allergy to castor oil derivatives (very rare)
Usage tips

Research notes
Research on polyglyceryl esters indicates they are mild, effective emulsifiers with good skin compatibility. Specific studies on Polyglyceryl-3 Ricinoleate are limited, but the broader class is well-documented for safety and performance in cosmetic formulations.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
