Ingredient review
Hydroxypropyl Dimethicone/Polysorbate 20 Crosspolymer
INCI: HYDROXYPROPYL DIMETHICONE/POLYSORBATE 20 CROSSPOLYMER
A gentle silicone-based stabilizer that helps keep formulas smooth and well-mixed without clogging pores.
In plain English
This ingredient is a special type of silicone that has been chemically linked with a gentle emulsifier (polysorbate 20). It acts like a tiny scaffold that holds oil and water together in a product, preventing them from separating. It also leaves a light, silky feel on the skin without being heavy or greasy.

Quick decision guide
Useful, but context matters
Hydroxypropyl Dimethicone/Polysorbate 20 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 Hydroxypropyl Dimethicone/Polysorbate 20 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 crosspolymer of silicone (dimethicone) and a mild surfactant (polysorbate 20), creating a stable network that improves product texture and emulsion stability.
How it works
In a formula, this crosspolymer forms a flexible film that helps suspend ingredients evenly. It reduces the need for traditional emulsifiers and can improve the spreadability and sensory feel of creams, lotions, and makeup.
Pros
Gentle on skin
Low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin types.
Improves formula stability
Helps keep creams and sunscreens from separating, ensuring consistent performance and texture.
Cons and cautions
Silicone-based
Some people prefer to avoid silicones due to environmental concerns or personal preference, though this ingredient is generally well-tolerated.
Limited independent research
Most safety data comes from manufacturer studies; long-term skin absorption data is not extensive.
Best for
- People who want lightweight, non-greasy moisturizers
- Those with normal to oily skin looking for a smooth makeup base
Use caution if
- Individuals who strictly avoid all silicone-based ingredients
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. Low irritation and comedogenic potential. No significant safety concerns reported in cosmetic use.
Research notes
Safety is supported by manufacturer data and general acceptance by cosmetic safety panels (e.g., CIR). Peer-reviewed studies on this specific crosspolymer are limited, but related silicone polymers have a strong safety record.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the EU and US FDA, within standard concentration limits.
- Common uses
- Moisturizers, Sunscreens, Foundations, Serums
- Environmental note
- Silicone crosspolymers may persist in the environment; however, this specific polymer is designed to be more readily biodegradable than some linear silicones.
Good to know
- Crosspolymers like this one are often used to replace traditional emulsifiers, which can sometimes be irritating.
- It is considered biodegradable in some formulations, but environmental impact varies.
