Polyglyceryl-3 Caprate/Caprylate/Succinate
INCI: POLYGLYCERYL-3 CAPRATE/CAPRYLATE/SUCCINATE
A gentle, non-irritating emulsifier that creates stable, lightweight textures without stripping the skin.
In plain English
This ingredient is a mild emulsifier made from glycerin and fatty acids from coconut or palm oil. It helps mix water and oil together so your lotion or cleanser stays smooth and doesn't separate. Because it's gentle, it's often used in products for sensitive 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/Succinate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

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
Polyglyceryl-3 Caprate/Caprylate/Succinate is a semi-synthetic emulsifier derived from glycerin and medium-chain fatty acids (capric and caprylic acid, from coconut or palm oil) combined with succinic acid. It belongs to the polyglyceryl ester family, known for being milder than traditional emulsifiers.
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 texture in creams and lotions. It also helps disperse other ingredients evenly and can improve the feel of a product on the skin.
Pros
Very gentle
Unlike some harsher emulsifiers, this one is unlikely to cause stinging or irritation, making it ideal for sensitive skin routines.
Lightweight feel
It helps create products that absorb quickly without leaving a heavy or sticky residue, which is great for oily or combination skin.
Cons and cautions
Environmental sourcing
It is often derived from palm or coconut oil, which can be associated with deforestation if not sustainably sourced.
Limited standalone use
In very thick or high-oil formulations, it may need to be paired with other emulsifiers to achieve the right consistency.
Best for
- People with sensitive or reactive skin
- Anyone looking for lightweight, non-greasy moisturizers or cleansers
Use caution if
- Those with a known allergy to coconut or palm derivatives (rare)
