Ingredient review
Polyglyceryl-3 Dicaprate
INCI: Polyglyceryl-3 Dicaprate
A gentle, non-irritating emulsifier that helps create stable, lightweight lotions and creams without stripping the skin.
In plain English
Polyglyceryl-3 Dicaprate is a mild ingredient that helps oil and water mix together in skincare products, so you get a smooth, creamy texture. It’s made from plant-based glycerin and capric acid (from coconut oil), so it’s considered gentle and unlikely to clog pores or cause irritation. Think of it as a helper that keeps your moisturizer or cleanser from separating into a watery mess.

Quick decision guide
Easy yes for most routines

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 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-3 Dicaprate is a semi-synthetic emulsifier created by combining glycerin (often from plant oils) with capric acid (a fatty acid from coconut or palm oil). It belongs to the polyglyceryl ester family, known for being milder than traditional emulsifiers like sodium lauryl sulfate.
How it works
In a cosmetic product, Polyglyceryl-3 Dicaprate sits at the boundary between oil and water droplets, reducing surface tension so they stay mixed together. This creates a stable, uniform lotion or cream that feels lightweight and spreads easily on the skin. It also has mild skin-conditioning properties, leaving a soft, non-greasy feel.
Pros
Gentle on skin
Polyglyceryl-3 Dicaprate has a very low irritation score, making it a safe choice for sensitive or reactive skin types.
Lightweight feel
It creates emulsions that feel silky and non-greasy, so your moisturizer won't sit heavy on the skin.
Cons and cautions
Not a standalone moisturizer
It's an emulsifier, not a humectant or occlusive, so it won't hydrate or lock in moisture on its own.
Potential palm oil sourcing
Capric acid is often derived from palm oil, which can raise environmental concerns unless certified sustainable.
Best for
- Anyone with normal, combination, or oily skin looking for a lightweight moisturizer
- Sensitive skin types who react to harsher emulsifiers
Use caution if
- Those with known allergies to coconut-derived ingredients (rare)
Usage tips
Safety summary
Polyglyceryl-3 Dicaprate is considered very safe for cosmetic use. It has low irritation and comedogenic potential, and no significant toxicity concerns have been reported in standard safety assessments.
Research notes
Research on polyglyceryl esters indicates they are mild, non-irritating, and effective emulsifiers. Specific studies on Polyglyceryl-3 Dicaprate are limited, but the broader class is well-documented as safe and gentle.
Common label clues
- Typical concentration
- Typically 1–5% in leave-on products, up to 10% in rinse-off cleansers
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA as a cosmetic ingredient. No known restrictions.
- Common uses
- Moisturizers, Cleansers, Serums, Sunscreens
- Environmental note
- Derived from renewable plant sources, but capric acid may come from palm oil. Look for products with RSPO-certified palm oil or coconut-derived alternatives for a more sustainable choice.
Good to know
- Polyglyceryl-3 Dicaprate is often used in 'waterless' or anhydrous formulas as a texture enhancer.
- It is considered biodegradable and has a favorable environmental profile compared to some synthetic emulsifiers.
