Ingredient review
Polyglyceryl-3 Caprate/Caprylate/Stearate/Dimer Dilinoleate Crosspolymer
INCI: Polyglyceryl-3 Caprate/Caprylate/Stearate/Dimer Dilinoleate Crosspolymer
A gentle, synthetic emulsifier that helps create stable, lightweight lotions and creams without clogging pores.
In plain English
This ingredient is a type of emulsifier, which means it helps water and oil mix together in a product so it doesn't separate. It's made from glycerin and fatty acids, and it's designed to give a smooth, silky feel without leaving a heavy or greasy residue on your skin.

Quick decision guide
Useful, but context matters
Polyglyceryl-3 Caprate/Caprylate/Stearate/Dimer Dilinoleate Crosspolymer 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-3 Caprate/Caprylate/Stearate/Dimer Dilinoleate Crosspolymer.
- 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 synthetic polymer made by linking glycerin-derived polyglyceryl-3 with a blend of capric, caprylic, stearic, and dimer dilinoleic acids. It acts as a crosspolymer, creating a network that stabilizes emulsions.
How it works
It sits at the boundary between oil and water droplets in a formula, reducing surface tension so the two phases stay mixed. Its crosspolymer structure also thickens the product slightly, giving a pleasant, spreadable texture that feels lightweight on the skin.
Pros
Lightweight feel
Provides a silky, non-greasy texture that absorbs quickly, making it ideal for daytime moisturizers and sunscreens.
Gentle on skin
Rated low for both irritation and comedogenicity, so it's unlikely to cause breakouts or stinging for most skin types.
Cons and cautions
Synthetic origin
Made from petrochemical or processed plant sources, which may not align with minimalist or 'clean' beauty preferences.
Limited independent safety data
While the individual components are well-studied, the specific crosspolymer form has less published research on skin absorption and long-term effects.
Best for
- People with oily or combination skin who want lightweight moisturizers
- Anyone looking for stable, non-separating lotions or sunscreens
Use caution if
- Those who strictly avoid all synthetic ingredients
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. The Cosmetic Ingredient Review (CIR) panel has reviewed similar polyglyceryl esters and found them safe. No significant irritation or sensitization has been reported.
Research notes
Research focuses on its function as an emulsifier and texture modifier. Studies on related polyglyceryl esters show low skin irritation and good stability. Direct studies on this specific crosspolymer are limited but consistent with the safety profile of its components.
Common label clues
- Typical concentration
- 1–5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Moisturizers, Sunscreens, Serums, Makeup removers
- Environmental note
- As a synthetic polymer, it may not be biodegradable. However, its low concentration in formulas means environmental impact is likely minimal.
Good to know
- It is often used in 'gel-cream' formulas because it creates a light, bouncy texture.
- The 'polyglyceryl-3' part means it's derived from glycerin, which is generally well-tolerated.
