Ingredient review
Polyglyceryl-5 Caprate
INCI: Polyglyceryl-5 Caprate
A mild, non-irritating emulsifier that helps create stable, lightweight textures and is well-tolerated by most skin types.
In plain English
Polyglyceryl-5 Caprate is a gentle ingredient that helps water and oil mix together in creams and lotions. It's made from glycerin and capric acid (a fatty acid from coconut or palm oil), so it's considered a mild, skin-friendly option. Unlike some harsher emulsifiers, it's unlikely to clog pores or cause irritation, making it a good choice for sensitive or acne-prone skin.

Quick decision guide
Easy yes for most routines
Polyglyceryl-5 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-5 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-5 Caprate is a semi-synthetic emulsifier created by combining glycerin (a natural humectant) with capric acid (a fatty acid derived from coconut or palm oil). It belongs to the polyglyceryl ester family, known for their mildness and compatibility with skin.
How it works
In a cosmetic product, Polyglyceryl-5 Caprate sits at the boundary between oil and water droplets, reducing surface tension so they can form a stable, uniform mixture. This prevents the product from separating and gives it a smooth, creamy texture. It also has mild skin-conditioning properties, helping to soften and smooth the skin's surface.
Pros
Very gentle on skin
Polyglyceryl-5 Caprate has a low irritation potential, making it suitable for sensitive, rosacea-prone, or eczema-prone skin types.
Non-comedogenic
It has a low comedogenic rating, meaning it is unlikely to clog pores or contribute to breakouts, even for acne-prone skin.
Cons and cautions
Lightweight texture may not suit dry skin
Because it creates light, fluid emulsions, it may not provide enough richness or occlusion for very dry or dehydrated skin.
Sustainability of source
Capric acid is often derived from palm or coconut oil, and unless certified sustainable, its production can have environmental impacts.
Best for
- People with sensitive or reactive skin looking for a gentle emulsifier
- Those with oily or combination skin who prefer lightweight textures
Use caution if
- Individuals seeking very rich, heavy moisturizers may find it too light
Usage tips
Safety summary
Polyglyceryl-5 Caprate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in the scientific literature.
Research notes
The safety of polyglyceryl esters, including Polyglyceryl-5 Caprate, has been reviewed by the Cosmetic Ingredient Review (CIR) panel, which concluded they are safe for use in cosmetics. Studies indicate very low skin irritation and sensitization potential.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and the European Commission, with no known restrictions on concentration.
- Common uses
- Moisturizers, Cleansers, Serums, Sunscreens
- Environmental note
- Derived from plant-based sources (glycerin and capric acid), but may involve palm oil. Look for RSPO-certified palm derivatives for more sustainable sourcing.
Good to know
- Polyglyceryl-5 Caprate is part of a family of polyglyceryl esters that are often used in 'clean' or 'green' beauty formulations.
- It is considered a PEG-free alternative to some traditional emulsifiers.
