Polyglyceryl-3 Dicocoate
INCI: POLYGLYCERYL-3 DICOCOATE
A mild, coconut-derived emulsifier that helps blend oil and water in creams and lotions without stripping the skin.
In plain English
Polyglyceryl-3 Dicocoate is a gentle ingredient made from coconut oil and glycerin. It acts like a bridge between oil and water, allowing them to mix smoothly in products like moisturizers and cleansers. Because it's derived from natural sources and is very mild, it's often used in formulations 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 Dicocoate.
- 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
A semi-synthetic emulsifier created by combining glycerin (a natural humectant) with fatty acids 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 form a stable, creamy mixture. This helps products feel smooth and spread easily on the skin without leaving a greasy residue.
Pros
Ultra-gentle on skin
Polyglyceryl-3 Dicocoate is one of the mildest emulsifiers available, making it ideal for sensitive skin types and baby care products.
Eco-friendly profile
It is biodegradable and derived from renewable plant sources, appealing to consumers looking for sustainable beauty choices.
Cons and cautions
Limited standalone emulsifying power
In very water-heavy formulas, it may need help from other emulsifiers or thickeners to maintain stability.
Less research than traditional options
Compared to decades-old emulsifiers like cetearyl alcohol, there is less published safety and efficacy data, though existing evidence is positive.
Best for
- Anyone looking for a gentle, non-irritating moisturizer or cleanser
- People with sensitive or eczema-prone skin who avoid harsh surfactants
Use caution if
- Those with a known allergy to coconut-derived ingredients (rare)
