Ingredient review
Polyglyceryl-2 Caprate
INCI: Polyglyceryl-2 Caprate
A gentle, non-irritating emulsifier that helps create stable, lightweight textures without stripping the skin.
In plain English
Polyglyceryl-2 Caprate is a mild ingredient that helps oil and water mix together in skincare products, like in a lotion or cream. It is made from glycerin (a natural moisturizer) and capric acid (a fatty acid from coconut or palm oil). Because it is very gentle, it is often used in products for sensitive skin or in oil cleansers that rinse off easily without leaving a greasy film.

Quick decision guide
Easy yes for most routines
Polyglyceryl-2 Caprate 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-2 Caprate.
- 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-2 Caprate is a semi-synthetic emulsifier created by combining glycerin with capric acid. It belongs to the polyglyceryl ester family, known for being milder than traditional emulsifiers like sodium lauryl sulfate.
How it works
It works by reducing the surface tension between oil and water, allowing them to blend into a stable, smooth emulsion. This helps create lightweight, non-greasy textures that spread easily and rinse off cleanly. It also has mild skin-conditioning properties, leaving skin feeling soft.
Pros
Very gentle on skin
Polyglyceryl-2 Caprate has a low irritation risk, making it a great choice for sensitive skin or for use around the eyes.
Lightweight feel
It helps create products that absorb quickly without a heavy or sticky residue, ideal for oily or combination skin.
Cons and cautions
Sustainability concerns
It is often derived from palm oil, which can be associated with deforestation unless sourced from certified sustainable suppliers.
Less common in drugstore products
You may find it more often in mid-range or premium brands, so it can be harder to find in budget-friendly options.
Best for
- People with sensitive or easily irritated skin
- Those who prefer lightweight, non-greasy moisturizers and cleansers
Use caution if
- Individuals with known allergies to coconut or palm oil derivatives (rare)
Usage tips
Safety summary
Polyglyceryl-2 Caprate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for sensitive skin. No significant safety concerns have been reported in regulatory reviews.
Research notes
Research on polyglyceryl esters indicates they are mild, biodegradable, and well-tolerated. Specific studies on Polyglyceryl-2 Caprate are limited, but the broader class is supported by safety assessments from the Cosmetic Ingredient Review (CIR) panel.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No known restrictions at typical concentrations.
- Common uses
- Cleansers, Moisturizers, Serums, Sunscreens
- Environmental note
- Derived from renewable plant sources (glycerin and capric acid). Palm oil sourcing may impact rainforests; look for RSPO-certified or coconut-derived versions.
Good to know
- Polyglyceryl-2 Caprate is part of a family of emulsifiers that are considered safer alternatives to ethoxylated ingredients like polysorbates.
- It is often used in 'waterless' or anhydrous formulas to improve rinseability.
