Polyglyceryl-10 Polyricinoleate
INCI: Polyglyceryl-10 Polyricinoleate
A mild, effective emulsifier derived from castor oil and glycerin, ideal for sensitive skin formulations.
In plain English
This ingredient is a helper molecule that allows water and oil to mix together in a stable cream or lotion. It is made from castor oil and glycerin, so it is considered gentle and unlikely to irritate skin. It is often used in products that aim to be mild and non-stripping.

Quick decision guide
Easy yes for most routines
Polyglyceryl-10 Polyricinoleate 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 Polyglyceryl-10 Polyricinoleate.
- 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
Polyglyceryl-10 Polyricinoleate is a semi-synthetic emulsifier created by combining polyglycerin (derived from glycerin) with polyricinoleic acid (derived from castor oil). It belongs to a family of polyglyceryl esters known for their mildness and biodegradability.
How it works
In a cosmetic formula, this ingredient sits at the boundary between oil and water droplets, reducing surface tension so they can form a stable emulsion. This prevents the product from separating into oil and water layers, ensuring a smooth, consistent texture.
Pros
Gentle on skin
Polyglyceryl-10 Polyricinoleate has a very low irritation risk, making it a great choice for sensitive skin formulas and baby products.
Plant-derived and eco-friendly
Sourced from castor oil and glycerin, it is biodegradable and considered more sustainable than some petroleum-based emulsifiers.
Cons and cautions
Limited formulation flexibility
It works best in specific oil-water ratios and may require additional stabilizers for very thin or very thick products.
Less common in drugstore products
Because it is a specialty ingredient, it is more often found in mid-to-high-end or natural-leaning brands, so it may be harder to find.
Best for
- People with sensitive or reactive skin
- Those looking for gentle, plant-derived emulsifiers in their skincare
Use caution if
- Individuals with known allergies to castor oil derivatives (rare)
Usage tips
Safety summary

- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. Generally recognized as safe when used as directed.
- Common uses
- Moisturizers, Cleansers, Serums, Sunscreens
- Environmental note
- Derived from renewable castor oil and glycerin, and considered biodegradable, making it a relatively eco-friendly choice.
Good to know
- Polyglyceryl esters are often used in 'no-poo' or low-poo hair cleansers because they are gentle and non-stripping.
- This ingredient is not a preservative, so products containing it still need a proper preservation system.
