Polyglyceryl-20 Heptadecabehenate/Laureate
INCI: Polyglyceryl-20 Heptadecabehenate/Laureate
A gentle, modern emulsifier that creates stable, lightweight formulas without the irritation potential of older emulsifiers.
In plain English
This ingredient is a type of emulsifier, meaning it helps water and oil mix together in products like lotions and creams. It's made from glycerin (a natural humectant) and fatty acids from plants. Because it's large and gentle, it's less likely to cause stinging or irritation compared to some older emulsifiers. It also helps create a smooth, non-greasy feel on the skin.

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 derived from glycerin and plant-based fatty acids (behenic and lauric acids). It belongs to the polyglyceryl ester family, known for being mild and biodegradable.
How it works
It works by surrounding oil droplets with a water-loving head, allowing them to mix evenly into water. This creates a stable, creamy emulsion that doesn't separate. Its large molecular structure means it stays mostly on the skin's surface, reducing the chance of irritation.
Pros
Gentle on skin
Its large molecular size means it's less likely to penetrate and cause irritation, making it ideal for sensitive skin.
Lightweight feel
It creates emulsions that feel smooth and non-greasy, so your moisturizer won't sit heavy on the skin.
Cons and cautions
Less common in mass-market products
You'll mostly find it in indie or premium brands, so it may not be in your usual drugstore lotion.
Not for ultra-thin liquids
It's best for creams and lotions; very watery serums may need a different emulsifier.
Best for
- Anyone with sensitive or reactive skin
- People who prefer modern, gentle emulsifiers over older ones
Use caution if
- Those looking for a very thick, balm-like texture (other emulsifiers may work better)
