Glyceryl Citrate Crosspolymer
INCI: GLYCERYL CITRATE CROSSPOLYMER
A gentle film-forming ingredient that helps products feel smooth and stay put without clogging pores.
In plain English
Glyceryl citrate crosspolymer is a lab-made ingredient that forms a thin, flexible film on your skin. It's used in lotions, serums, and sunscreens to make them spread more evenly, feel silky, and last longer. Think of it like a lightweight, invisible shield that helps the product stay where you put it and gives a smooth finish.

Quick decision guide
Useful, but context matters
Glyceryl Citrate Crosspolymer 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 Glyceryl Citrate Crosspolymer.
- 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
A crosspolymer created by linking glycerin (a common moisturizing alcohol) with citric acid (a fruit-derived acid). The result is a large molecule that can form a film on the skin.
How it works
When applied, the crosspolymer molecules spread out and link together to create a thin, breathable film. This film helps other ingredients stay on the skin longer, reduces water loss, and gives a smooth, non-sticky feel.
Pros
Smooth, silky feel
Creates a velvety, non-greasy finish that makes products more pleasant to apply, especially for oily or combination skin.
Improves product performance
Helps active ingredients and sunscreens stay on the skin longer, so you get more benefit from each application.
Cons and cautions
Can feel tight on dry skin
The film may feel slightly drying or tight if your skin is already very dry, so pair with a good moisturizer.
Not a standalone hydrator
It doesn't add moisture on its own; it works best as part of a formula with humectants and emollients.
Best for
- Anyone wanting a smoother, more elegant product texture
- People who use sunscreens and want better water resistance
Use caution if
- Those who prefer completely film-free, minimal-ingredient routines
Usage tips
Safety summary
Glyceryl citrate crosspolymer is considered safe for cosmetic use. It has low irritation and comedogenic potential, making it suitable for most skin types, including sensitive skin.
Research notes
While not extensively studied alone, crosspolymers of glycerin and citric acid are well-established in cosmetics as safe film formers. Their safety is supported by industry use and regulatory approvals.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the FDA (US) and EU CosIng database. No known restrictions at typical use levels.
- Common uses
- Moisturizers, Serums, Sunscreens, Makeup
- Environmental note
- Made from plant-derived glycerin and citric acid, and is biodegradable, so it has a lower environmental impact than many synthetic polymers.
Good to know
- Derived from renewable glycerin and citric acid, making it a more sustainable choice than some petroleum-based film formers.
- Often used in 'clean' or 'green' beauty formulas because it's biodegradable.
