Ingredient review
Polyglyceryl-10 Trilaurate
INCI: Polyglyceryl-10 Trilaurate
A mild, non-irritating emulsifier that helps create stable, lightweight creams and lotions without stripping the skin.
In plain English
Polyglyceryl-10 Trilaurate is a gentle emulsifier made from glycerin and lauric acid (a fatty acid found in coconut oil). It helps mix oil and water in skincare products so they stay smooth and don't separate. Because it's derived from natural sources and has a large, mild molecule, it's very unlikely to clog pores or cause irritation, making it a favorite in sensitive-skin and non-comedogenic formulas.

Quick decision guide
Easy yes for most routines
Polyglyceryl-10 Trilaurate 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 Trilaurate.
- 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 esterifying polyglycerin-10 (a polymer of glycerin) with three molecules of lauric acid. It belongs to the polyglyceryl ester family, known for being exceptionally mild and biodegradable.
How it works
It reduces the surface tension between oil and water, allowing them to form a stable, uniform mixture. In a cream or lotion, it helps the product spread evenly on the skin and leaves a light, non-greasy feel. It also has mild skin-conditioning properties, helping to soften and smooth the skin's surface.
Pros
Extremely gentle
Polyglyceryl-10 Trilaurate has a large molecular structure that is too big to penetrate deeply into the skin, so it sits on the surface and rarely causes irritation or stinging.
Won't clog pores
It scores very low on the comedogenic scale, making it a safe choice for acne-prone or oily skin types who need a lightweight, non-greasy moisturizer.
Cons and cautions
Limited oil-handling capacity
On its own, it may not stabilize very high oil-content formulas (like heavy balms or oil serums) and often needs a co-emulsifier for thicker textures.
Less widely available
Compared to common emulsifiers like cetearyl alcohol, polyglyceryl-10 trilaurate is used more in niche or 'clean beauty' brands, so it may be harder to find in conventional drugstore products.
Best for
- People with sensitive or reactive skin
- Those looking for non-comedogenic moisturizers and cleansers
- Anyone who prefers plant-derived, biodegradable ingredients
Use caution if
- Those with a known allergy to coconut-derived ingredients (rare)
- Formulators needing a very high-HLB emulsifier for oil-rich products
Usage tips
Safety summary
Polyglyceryl-10 Trilaurate is considered very safe for cosmetic use. It has low acute toxicity, is non-irritating to skin and eyes, and is not a sensitizer. The Cosmetic Ingredient Review (CIR) panel has reviewed similar polyglyceryl esters and found them safe as used.
Research notes
Research on polyglyceryl esters indicates they are mild, non-irritating emulsifiers with good skin compatibility. Studies show that polyglyceryl-10 esters have low cytotoxicity and do not disrupt the skin barrier. While specific studies on trilaurate are limited, the broader class is well-supported.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics worldwide, including the EU, USA (FDA), and Japan. No concentration restrictions are typically imposed, but good formulation practice suggests using the minimum effective level.
- Common uses
- Moisturizers, Cleansers, Serums, Sunscreens
- Environmental note
- Derived from renewable plant sources (glycerin and coconut oil) and is readily biodegradable, making it a more sustainable choice compared to many petroleum-based emulsifiers.
Good to know
- Polyglyceryl esters are often labeled as 'polyglyceryl-X' where X is the number of glycerin units; higher numbers (like 10) mean larger, milder molecules.
- It is often used in 'non-comedogenic' and 'sensitive skin' product lines.
- The ingredient is biodegradable and considered eco-friendly compared to some synthetic emulsifiers.
