Dimethicone PEG-8 Polyacrylate
INCI: Dimethicone PEG-8 Polyacrylate
A gentle silicone film-former that helps products feel silky and stay put, but may not suit those avoiding silicones.
In plain English
This is a synthetic silicone ingredient that forms a thin, flexible film on your skin. It helps other ingredients spread smoothly, makes the product feel silky, and can improve water resistance. Think of it like a lightweight, breathable shield that helps your makeup or sunscreen last longer without feeling heavy.

Quick decision guide
Useful, but context matters
Dimethicone PEG-8 Polyacrylate 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 Dimethicone PEG-8 Polyacrylate.
- 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 silicone polymer (a large molecule made of repeating units) that combines dimethicone (a common silicone) with polyethylene glycol (PEG) and polyacrylate chains. It is designed to create a uniform, flexible film on the skin.
How it works
When applied, the water in the product evaporates, leaving behind a thin, even layer of the polymer. This film helps lock in other ingredients, reduces water loss from the skin, and gives a smooth, silky feel. It also helps suspend pigments and active ingredients for even application.
Pros
Silky, lightweight feel
Creates a smooth, non-greasy finish that many people find pleasant, especially in primers and sunscreens.
Improves wear and water resistance
Helps makeup and sunscreen stay in place longer, even in humid conditions or during light activity.
Cons and cautions
Not silicone-free
Contains silicone, which some people choose to avoid for personal or environmental reasons.
May require double cleansing
The film it forms can be resistant to water and mild cleansers, so an oil-based cleanser may be needed for thorough removal.
Best for
- People looking for long-wearing makeup or water-resistant sunscreen
- Those who enjoy a silky, non-greasy finish in their skincare
Use caution if
- Individuals who prefer silicone-free or minimal-ingredient routines
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk. However, as with any ingredient, patch test if you have sensitive skin.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found dimethicone and related silicone polymers to be safe as used in cosmetics. Specific studies on Dimethicone PEG-8 Polyacrylate are limited, but its components are well-studied and considered low-risk.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU, and many other regions. No specific concentration restrictions are common, but formulators follow good manufacturing practices.
- Common uses
- Moisturizers, Sunscreens, Primers, Color Cosmetics
- Environmental note
- Silicones like dimethicone are generally not biodegradable and can accumulate in the environment. Some manufacturers are working on more eco-friendly alternatives.
Good to know
- PEG (polyethylene glycol) in the name refers to a processing aid that helps the silicone mix with water-based ingredients.
- This ingredient is often used in 'hybrid' sunscreens that combine chemical and physical filters for a more elegant texture.
