Bis-Vinyl Dimethicone/Dimethicone Copolymer
INCI: BIS-VINYL DIMETHICONE/DIMETHICONE COPOLYMER
A silicone polymer that creates a smooth, flexible film on skin or hair, improving product feel and wear without clogging pores.
In plain English
This is a type of silicone that forms a thin, flexible, breathable film on your skin or hair. It helps makeup glide on smoothly, stay in place longer, and feel silky rather than sticky or greasy. Think of it as a lightweight, invisible shield that also helps other ingredients spread evenly.

Quick decision guide
Useful, but context matters
Bis-Vinyl Dimethicone/Dimethicone Copolymer 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 Bis-Vinyl Dimethicone/Dimethicone Copolymer.
- 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 silicone polymer made by crosslinking vinyl dimethicone with dimethicone. It is a large molecule that does not penetrate the skin, sitting on the surface to create a smooth, even film.
How it works
When applied, the polymer chains link together to form a continuous, flexible film. This film evens out the skin's texture, fills in fine lines and pores temporarily, and helps other ingredients (like pigments or UV filters) adhere better and last longer. It also controls the thickness and feel of the product.
Pros
Smooth, silky finish
Creates a velvety, non-greasy feel on skin and hair, making products more pleasant to apply and wear.
Improves wear time
Forms a flexible film that helps makeup and sunscreens stay put longer without flaking or fading.
Cons and cautions
May feel heavy on oily skin
Some users with very oily skin find silicone films can feel slippery or contribute to a shiny look.
Requires thorough removal
The film can be resistant to water and mild cleansers, so you may need an oil-based cleanser or double cleansing to fully remove it.
Best for
- People who want long-wearing makeup or sunscreen
- Those with normal to dry skin looking for a smooth, non-sticky finish
Use caution if
- Individuals who prefer silicone-free or minimalist routines
Usage tips
Safety summary
Bis-Vinyl Dimethicone/Dimethicone Copolymer is considered safe for use in cosmetics. It is non-irritating, non-sensitizing, and does not penetrate the skin. Regulatory bodies worldwide have approved its use without restrictions at typical concentrations.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that dimethicone copolymers are safe as used in cosmetics. Studies show they do not cause skin irritation or sensitization. Evidence for efficacy is based on formulation science rather than clinical trials, but the ingredient is widely used and well-tolerated.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and EU CosIng database, with no known restrictions at typical use levels.
- Common uses
- Primers, Foundations, Sunscreens, Long-wear makeup, Hair serums
- Environmental note
- Silicones like this one are synthetic and not biodegradable. However, this specific polymer is large and does not readily absorb into the environment; its environmental impact is considered low compared to smaller cyclic silicones.
Good to know
- This ingredient is considered non-comedogenic and safe for most skin types.
- It is often used in combination with other silicones to fine-tune texture and feel.
