Ingredient review
Dicaprolactone Ethoxyacrylate HEMA IPDI
INCI: Dicaprolactone Ethoxyacrylate HEMA IPDI
A synthetic polymer that helps makeup last longer and resist water, but offers no skincare benefit.
In plain English
This is a man-made ingredient that forms a thin, flexible film on your skin. It helps makeup stay put longer and makes it more resistant to water and sweat. Think of it like a clear, invisible shield that holds pigments in place. It doesn't moisturize or treat your skin—it's purely a performance ingredient for long-wear cosmetics.

Quick decision guide
Useful, but context matters
Dicaprolactone Ethoxyacrylate HEMA IPDI 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 Dicaprolactone Ethoxyacrylate HEMA IPDI.
- 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 synthetic copolymer created by reacting caprolactone, ethoxyacrylate, HEMA (hydroxyethyl methacrylate), and IPDI (isophorone diisocyanate). It belongs to the family of film-forming polymers used in cosmetics.
How it works
When applied, the solvent evaporates and the polymer chains link together to form a continuous, flexible film on the skin or hair. This film traps pigments and other ingredients, reducing transfer, smudging, and water wash-off. It also adds a slight thickening effect to the product texture.
Pros
Excellent wear time
Creates a durable film that helps makeup last through sweat, humidity, and daily activity without smudging.
Water-resistant performance
Forms a barrier that resists water and moisture, making it ideal for waterproof mascaras and long-wear foundations.
Cons and cautions
No skincare benefit
This ingredient is purely functional—it does not hydrate, soothe, or protect the skin in any way.
Can feel tight or drying
On dry or sensitive skin, the film may create a tight sensation and may not be comfortable for all-day wear.
Best for
- People who want long-lasting, transfer-proof makeup
- Those with normal to oily skin who prefer matte finishes
Use caution if
- Individuals with very dry or compromised skin barriers who may find film-formers uncomfortable
Usage tips
Safety summary
Dicaprolactone Ethoxyacrylate HEMA IPDI is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential. However, as a film-former, it may cause tightness or discomfort on very dry or sensitive skin. Always patch test new products.
Research notes
Limited peer-reviewed studies specifically on this exact polymer, but the class of acrylate-based film-formers is well-studied for safety and performance. Regulatory reviews (e.g., CIR) have found similar acrylate copolymers safe in cosmetics.
Common label clues
- Typical concentration
- 1–10% in leave-on formulas
- 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 mascaras, Lip products, Sunscreens
- Environmental note
- As a synthetic polymer, it is not biodegradable. Its environmental impact depends on formulation and disposal methods.
Good to know
- This ingredient is often found in '24-hour wear' or 'waterproof' makeup claims.
- It is not water-soluble, so standard foaming cleansers may not remove it completely.
- The polymer is considered safe for use in cosmetics by major regulatory bodies at typical concentrations.
