Ingredient review
Silicone-Polymer Film Former
INCI: IPDI/DI-C12-13 ALKYL TARTRATE/BIS-HYDROXYETHOXYPROPYL DIMETHICONE COPOLYMER
A synthetic film former that helps makeup and sunscreen stay put longer without feeling overly stiff or sticky.
In plain English
This ingredient is a man-made polymer that combines silicone and other compounds to form a thin, flexible film on your skin or hair. It's like a clear, breathable shield that helps products resist water, sweat, and smudging. Because it's a silicone hybrid, it tends to feel smoother and less heavy than some older film formers.

Quick decision guide
Useful, but context matters
Silicone-Polymer Film Former 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 Silicone-Polymer Film Former.
- 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 copolymer synthesized from isophorone diisocyanate (IPDI), a C12-13 alkyl tartrate (a fatty acid derivative), and a silicone-modified diol. This combination creates a large molecule that can spread into a uniform film.
How it works
When applied, the solvent (water or alcohol) evaporates, leaving behind a continuous, flexible film. The silicone portion gives a silky feel and water resistance, while the tartrate and IPDI parts add flexibility and adhesion to the skin or hair surface.
Pros
Long-wear performance
Forms a flexible film that helps makeup and sunscreen resist water, sweat, and rubbing, so you need fewer touch-ups.
Comfortable feel
Unlike some older film formers, this silicone hybrid feels smooth and lightweight on skin, not stiff or tight.
Cons and cautions
Requires thorough removal
Because it's water-resistant, you'll likely need an oil-based cleanser or a double-cleansing routine to fully remove it, which may be inconvenient.
Synthetic composition
It's a man-made polymer, so it won't appeal to those seeking 100% natural or biodegradable ingredients.
Best for
- People who want long-lasting, transfer-resistant makeup
- Those who use water-resistant sunscreens for outdoor activities
Use caution if
- Individuals who prefer exclusively natural or plant-derived ingredients
Usage tips
Safety summary
Generally recognized as safe for topical cosmetic use. Low irritation and comedogenic potential. No significant safety concerns reported in the scientific literature at typical use levels.
Research notes
Limited peer-reviewed studies specific to this exact copolymer, but the class of silicone-polyurethane hybrid film formers is well-documented for low irritation and effective film formation. Safety assessments rely on analogy to similar polymers.
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 specific restrictions at typical use levels.
- Common uses
- Long-wear foundations, Waterproof mascara, Sunscreens, Hair styling products, Lip products
- Environmental note
- As a silicone-containing polymer, it may not be readily biodegradable. However, it is used in low concentrations and is not known to bioaccumulate significantly.
Good to know
- This ingredient is often found in 'long-wear' or '24-hour' makeup formulas.
- It is considered safe for use in cosmetics by major regulatory bodies at typical concentrations.
