Ingredient review
Polyglyceryl-20 Hexacaprylate
INCI: POLYGLYCERYL-20 HEXACAPRYLATE
A mild, plant-based emulsifier that creates stable, silky formulas without stripping the skin.
In plain English
Polyglyceryl-20 Hexacaprylate is a gentle ingredient that helps water and oil mix together in your skincare products. It comes from glycerin (a natural moisturizer) and caprylic acid (found in coconut oil). Because it's made with a long chain of glycerin units, it's very mild and unlikely to irritate or clog pores. You'll find it in lotions, creams, and cleansers where it gives a smooth, non-greasy texture.

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 linking glycerin with caprylic acid (a fatty acid from coconut oil). 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 uniform, creamy texture that spreads easily on the skin and helps other ingredients mix well.
Pros
Ultra-gentle on skin
Its large molecular structure makes it less likely to penetrate or irritate, ideal for sensitive or compromised skin barriers.
Non-comedogenic
Rated low on the comedogenic scale, so it won't clog pores or contribute to breakouts for most skin types.
Cons and cautions
Semi-synthetic origin
While derived from natural sources, it undergoes chemical processing, which may not appeal to fans of purely natural skincare.
Limited standalone benefit
It's a functional ingredient that improves texture and stability but doesn't actively hydrate or treat the skin on its own.
Best for
- People with sensitive or reactive skin
- Anyone looking for lightweight, non-greasy moisturizers
Use caution if
- Those who prefer 100% natural, unprocessed ingredients
Usage tips
Safety summary
Polyglyceryl-20 Hexacaprylate is considered very safe for cosmetic use. It has a low irritation and comedogenic risk, and is well-tolerated even by sensitive skin. No significant safety concerns have been reported in standard use concentrations.
Research notes
While not extensively studied on its own, the broader family of polyglyceryl esters has a strong safety record. They are recognized as mild surfactants and emulsifiers in dermatological literature, with low potential for skin irritation or sensitization.
Common label clues
- Typical concentration
- 1% to 5% of the formula
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA as a safe emulsifier.
- Common uses
- Moisturizers, Serums, Cleansers, Sunscreens
- Environmental note
- Derived from plant-based glycerin and coconut oil, and considered biodegradable, making it a more eco-friendly choice compared to some synthetic emulsifiers.
Good to know
- Polyglyceryl esters are often used in 'clean beauty' formulas because they are biodegradable and derived from renewable plant sources.
- The number '20' refers to the average number of glycerin units, which contributes to its mildness.
