Ingredient review
Polyglyceryl-20 Octadecabehenate/Laurate
INCI: POLYGLYCERYL-20 OCTADECABEHENATE/LAURATE
A mild, plant-derived emulsifier that creates stable, lightweight textures without clogging pores.
In plain English
This ingredient is a helper molecule that allows oil and water to mix smoothly in your skincare products, so you get a consistent, creamy texture. It is made from glycerin and fatty acids from plants, and it is very gentle on the skin. Because it is large and mild, it is unlikely to cause irritation or breakouts, making it a favorite in sensitive-skin formulas.

Quick decision guide
Easy yes for most routines
Polyglyceryl-20 Octadecabehenate/Laurate 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-20 Octadecabehenate/Laurate.
- 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 (a plant-derived humectant) with behenic and lauric acids (long-chain fatty acids from sources like rapeseed and coconut). It is a large molecule that sits on the surface of oil droplets, preventing them from separating from water.
How it works
When you apply a product containing this ingredient, it helps the formula spread evenly and feel smooth. It works by reducing the surface tension between oil and water, creating a stable emulsion. On the skin, it leaves a light, non-greasy film that can help other ingredients penetrate better without feeling heavy.
Pros
Gentle on skin
This emulsifier has a very low irritation risk, making it ideal for sensitive skin types and baby care products.
Lightweight feel
It creates emulsions that feel light and silky on the skin, without the heavy or sticky residue some emulsifiers leave behind.
Cons and cautions
Limited research
Compared to classic emulsifiers, there are fewer peer-reviewed studies on this specific ingredient, though its components are well-studied.
Not for all textures
It may not provide enough thickness for very rich creams or balms, so formulators often combine it with other thickeners.
Best for
- People with sensitive or reactive skin
- Those looking for lightweight, non-greasy moisturizers
Use caution if
- Individuals with known allergies to polyglycerin derivatives (rare)
Usage tips
Safety summary
Polyglyceryl-20 Octadecabehenate/Laurate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in regulatory reviews.
Research notes
While specific studies on this exact ingredient are limited, the safety of polyglyceryl esters and long-chain fatty acids is well-established. A 2020 review by the Cosmetic Ingredient Review (CIR) found polyglyceryl esters to be safe in leave-on and rinse-off products.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA (as part of generally recognized safe emulsifiers).
- Common uses
- Moisturizers, Cleansers, Serums, Sunscreens
- Environmental note
- Derived from renewable plant sources (glycerin, rapeseed, coconut), and its large molecular structure suggests low environmental persistence.
Good to know
- This ingredient is often used in 'clean beauty' formulations because it is derived from plant sources.
- It is a large molecule, so it stays mostly on the skin's surface rather than penetrating deeply.
