Polyglyceryl-10 Tridecanoate
INCI: Polyglyceryl-10 Tridecanoate
A mild, non-irritating emulsifier that helps create stable, creamy textures without stripping the skin.
In plain English
Polyglyceryl-10 Tridecanoate is a gentle ingredient that helps oil and water mix together in skincare products. It is made from glycerin (a natural moisturizing substance) and a fatty acid from plants. Because it is very mild, it is often used in products for sensitive or dry skin. It also leaves a soft, smooth feel on the skin without being greasy.

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 Tridecanoate.
- 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 made by combining polyglycerin (from glycerin) with tridecanoic acid, a fatty acid found in plant oils. It belongs to the polyglyceryl ester family, known for being gentle and biodegradable.
How it works
It reduces the surface tension between oil and water, allowing them to blend into a stable emulsion. This creates a smooth, uniform cream or lotion. It also forms a thin film on the skin that helps lock in moisture and leaves a soft, non-sticky finish.
Pros
Extremely gentle on skin
Polyglyceryl-10 Tridecanoate has a low irritation risk and is well-tolerated even by sensitive or eczema-prone skin, making it a safe choice for daily use.
Improves product texture
It creates smooth, creamy emulsions that feel light and non-greasy, enhancing the user experience of moisturizers and sunscreens.
Cons and cautions
Not a treatment ingredient
This ingredient is primarily a texture and stability enhancer, so it won't directly address concerns like acne, hyperpigmentation, or aging.
Limited standalone benefit
On its own, it does not provide significant moisturizing or active benefits; it works best as part of a well-formulated product.
Best for
- People with sensitive or reactive skin who need gentle formulas
- Anyone looking for lightweight, non-greasy moisturizers or sunscreens
Use caution if
- Those seeking a targeted treatment ingredient (it is a texture and stability aid, not an active)
