Ingredient review
Polyglyceryl-6 Dicaprate
INCI: Polyglyceryl-6 Dicaprate
A mild, plant-derived emulsifier that helps create stable, lightweight textures without stripping the skin.
In plain English
Polyglyceryl-6 Dicaprate is a gentle ingredient made from glycerin and capric acid (a fatty acid from coconut or palm oil). Its main job is to help oil and water mix together in a product so it stays smooth and doesn't separate. It also leaves a soft, non-greasy feel on the skin. Because it's derived from natural sources and is very mild, it's often used in sensitive-skin and clean-beauty formulas.

Quick decision guide
Easy yes for most routines
Polyglyceryl-6 Dicaprate 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-6 Dicaprate.
- 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
Polyglyceryl-6 Dicaprate is a semi-synthetic emulsifier created by combining polyglycerin (a polymer of glycerin) with capric acid, a medium-chain fatty acid typically sourced from coconut or palm kernel oil. It belongs to the polyglyceryl ester family, known for being gentle and biodegradable.
How it works
In a cosmetic formula, Polyglyceryl-6 Dicaprate positions itself at the boundary between oil and water droplets, reducing surface tension so they can blend into a stable emulsion. This prevents the product from separating into layers. It also deposits a thin, moisturizing film on the skin, improving texture without clogging pores.
Pros
Ultra-gentle on skin
Polyglyceryl-6 Dicaprate has a very low irritation score, making it ideal for sensitive-skin products, including those for eczema-prone or reactive skin.
Lightweight feel
Unlike some emulsifiers that leave a heavy or waxy residue, this ingredient creates a silky, non-sticky finish that works well in gel-creams and lightweight lotions.
Cons and cautions
Sustainability concerns
The capric acid is often sourced from palm or coconut oil. Without certified sustainable sourcing, this can contribute to deforestation or habitat loss.
Less research than traditional emulsifiers
While safety data is positive, Polyglyceryl-6 Dicaprate has fewer long-term studies compared to decades-old emulsifiers like cetearyl alcohol.
Best for
- Anyone looking for lightweight, non-greasy moisturizers or serums
- People with sensitive or easily irritated skin who want gentle formulas
Use caution if
- Those with a known allergy to coconut or palm derivatives (rare but possible)
Usage tips
Safety summary
Polyglyceryl-6 Dicaprate is considered safe for cosmetic use at typical concentrations. It has low irritation and sensitization potential, and no significant toxicity concerns have been reported in available studies.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) and the European Chemicals Agency (ECHA) support the safety of polyglyceryl esters. Specific studies on Polyglyceryl-6 Dicaprate are limited, but the broader class is well-tolerated and non-irritating.
Common label clues
- Typical concentration
- Typically 1–5% in leave-on products, up to 10% in rinse-off products
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets. The Cosmetic Ingredient Review (CIR) panel has evaluated polyglyceryl esters and found them safe as used.
- Common uses
- Moisturizers, Serums, Cleansers, Sunscreens
- Environmental note
- Derived from plant-based glycerin and fatty acids, this ingredient is biodegradable. However, palm oil sourcing may impact rainforests unless certified sustainable (e.g., RSPO).
Good to know
- Polyglyceryl-6 Dicaprate is often listed near the middle of an ingredient list, indicating moderate usage levels
- It is compatible with both synthetic and natural oils, making it versatile for formulators
