Ingredient review
Polysorbate
INCI: Polysorbate 20, Polysorbate 60, Polysorbate 80
Polysorbates are widely used, gentle emulsifiers that keep your skincare products stable and easy to rinse off.
In plain English
Polysorbates are ingredients that help oil and water mix together in your skincare products, so they don't separate into layers. They also help cleansers rinse away cleanly without leaving a greasy film. Think of them as the 'peacekeepers' that keep the formula smooth and effective.

Quick decision guide
Useful, but context matters
Polysorbate 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 Polysorbate.
- 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
strongThere is a stronger practical or research basis for the ingredient role described here.
What it is
Polysorbates are a family of semi-synthetic emulsifiers derived from sorbitol (a sugar alcohol) and fatty acids, processed with ethylene oxide. Common types include Polysorbate 20, 60, and 80, each with slightly different properties.
How it works
Polysorbates have a water-loving head and an oil-loving tail. When added to a formula, they surround oil droplets and suspend them in water, creating a stable emulsion. This prevents separation and ensures every pump delivers a consistent mix of ingredients.
Pros
Stable emulsions
Polysorbates prevent your lotions and creams from separating into oil and water layers, so you get a consistent product every time.
Gentle cleansing
They help cleansers remove makeup and dirt without stripping the skin's natural moisture barrier, making them suitable for daily use.
Cons and cautions
Potential trace contaminants
Manufacturing can produce trace amounts of 1,4-dioxane, a possible carcinogen, but reputable brands purify to safe levels regulated by authorities.
May irritate very sensitive skin
In high concentrations, polysorbates can disrupt the skin barrier slightly, leading to dryness or irritation for those with conditions like eczema.
Best for
- Anyone using lotions, creams, or cleansers that need stable texture
- People with normal to oily skin looking for effective cleansers
Use caution if
- Those with known allergies to polysorbates (rare)
- Individuals with severely compromised skin barriers may prefer gentler emulsifiers
Usage tips
Safety summary
Polysorbates are considered safe for most people in typical cosmetic concentrations. The main safety concern is trace 1,4-dioxane contamination, which is tightly regulated. Allergic reactions are rare. Overall, they are well-tolerated and widely used.
Research notes
Multiple safety reviews by the Cosmetic Ingredient Review (CIR) and other bodies have concluded that polysorbates are safe in cosmetics at current usage levels. Studies show low skin irritation and sensitization potential.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission, with concentration limits for certain applications. The Cosmetic Ingredient Review (CIR) panel has deemed them safe as used.
- Common uses
- Cleansers, Moisturizers, Serums, Makeup removers, Sunscreens
- Environmental note
- Polysorbates are biodegradable but can be derived from palm oil, so look for sustainably sourced versions if environmental impact is a concern.
Good to know
- Polysorbate 80 is the most common type in skincare and is also used in food and medicine.
- The '20', '60', or '80' refers to the fatty acid used (lauric, stearic, or oleic acid), affecting its solubility.
