Ingredient review
PEG-10 Dimethicone/Vinyl Dimethicone Crosspolymer
INCI: PEG-10 Dimethicone/Vinyl Dimethicone Crosspolymer
A silicone polymer that stabilizes formulas and gives a silky, smooth feel without clogging pores.
In plain English
This is a silicone-based ingredient that helps mix water and oil in a product so they don't separate. It also creates a light, silky film on your skin that makes the product spread easily and feel smooth. Think of it as a helper that keeps your lotion or foundation from turning watery or lumpy, and gives it that nice glide when you apply it.

Quick decision guide
Useful, but context matters
PEG-10 Dimethicone/Vinyl Dimethicone 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 PEG-10 Dimethicone/Vinyl Dimethicone 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 synthetic silicone polymer where PEG (polyethylene glycol) chains are attached to a dimethicone backbone and crosslinked with vinyl dimethicone. This creates a three-dimensional network that can hold both water and oil, making it an effective emulsifier and texture modifier.
How it works
When added to a formula, it forms a flexible network that stabilizes the mixture of water and oil droplets. During application, it spreads into a thin, breathable film that feels silky and reduces friction. It also helps other ingredients stay evenly distributed on the skin.
Pros
Excellent texture enhancer
Gives products a silky, non-sticky feel that makes application smooth and pleasant.
Low irritation risk
Generally well-tolerated by most skin types, including sensitive skin, with very low reported irritation.
Cons and cautions
Synthetic origin
Derived from petrochemicals, which may not align with natural or eco-conscious skincare preferences.
Can feel heavy on oily skin
In high concentrations, the film it forms may feel slightly occlusive or greasy for those with very oily skin.
Best for
- Anyone who wants a silky, smooth texture in their moisturizer or primer
- People with normal to dry skin who enjoy a soft, velvety finish
Use caution if
- Those who strictly avoid silicones or synthetic ingredients
- Individuals with very oily skin who prefer matte, silicone-free formulas
Usage tips
Safety summary
Considered safe for cosmetic use at typical concentrations. The PEG component is well-studied, and the crosspolymer structure reduces skin penetration, minimizing any potential irritation. No significant safety concerns have been raised by regulatory bodies.
Research notes
Research on this specific crosspolymer is limited, but the broader class of dimethicone crosspolymers is well-documented for safety and efficacy as emulsifiers and texture modifiers. Studies show low skin irritation and sensitization potential.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the FDA (USA) and EU CosIng database, with no known restrictions at typical use levels.
- Common uses
- Moisturizers, Serums, Sunscreens, Foundations, Primers
- Environmental note
- As a silicone-based polymer, it is not biodegradable and may accumulate in the environment. Some brands are moving toward biodegradable alternatives.
Good to know
- This ingredient is often used in 'silicone blend' primers to create a smooth base for makeup.
- It is not water-soluble, so it may require a double cleanse with an oil-based cleanser to remove fully.
