Ingredient review
Polysorbate 85
INCI: Polysorbate 85
Polysorbate 85 is a gentle emulsifier that helps mix oil and water in formulas, with a low risk of irritation or clogged pores.
In plain English
Polysorbate 85 is a helper ingredient that allows oil and water to blend together smoothly in your skincare products. It's made from sorbitol (a sugar alcohol) and oleic acid (a fatty acid from plant oils), then processed to become water-soluble. This means it can surround oil droplets and suspend them in water, creating stable creams, lotions, and cleansers. It's considered very gentle on skin and unlikely to cause breakouts or irritation.

Quick decision guide
Useful, but context matters
Polysorbate 85 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 85.
- 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
Polysorbate 85 is a semi-synthetic emulsifier derived from sorbitol and oleic acid. It belongs to the polysorbate family, which are widely used in cosmetics and food as mild surfactants and emulsifiers.
How it works
In a cosmetic product, Polysorbate 85 sits at the boundary between oil and water molecules. Its water-loving (hydrophilic) head dissolves in water, while its oil-loving (lipophilic) tail dissolves in oil. This reduces surface tension and allows the two phases to mix into a stable emulsion, preventing separation over time.
Pros
Gentle on skin
Polysorbate 85 has a low irritation profile, making it suitable for sensitive skin types and daily use.
Non-comedogenic
It does not clog pores for the vast majority of users, so it's safe for acne-prone skin.
Cons and cautions
Semi-synthetic origin
Some consumers prefer fully natural emulsifiers; Polysorbate 85 is processed in a lab, though from plant-derived starting materials.
Rare sensitivity
A very small number of people may experience mild stinging or redness, especially if used at high concentrations.
Best for
- People with normal to oily skin looking for lightweight emulsions
- Anyone using oil-based serums or makeup removers that need to rinse off cleanly
Use caution if
- Individuals with known rare allergies to polysorbates (very uncommon)
Usage tips
Safety summary
Polysorbate 85 is considered safe for cosmetic use at typical concentrations. It has low acute toxicity, is not a skin sensitizer, and is non-comedogenic. The Cosmetic Ingredient Review (CIR) panel has reviewed polysorbates and found them safe as used.
Research notes
Studies on polysorbates show they are well-tolerated on skin and mucous membranes. Research supports their use as mild emulsifiers with minimal irritation potential. No significant safety concerns have been identified in cosmetic applications.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. Generally recognized as safe (GRAS) for food use.
- Common uses
- Cleansers, Moisturizers, Makeup removers, Serums
- Environmental note
- Polysorbate 85 is biodegradable under standard wastewater treatment conditions, but its production involves chemical processing.
Good to know
- Polysorbate 85 is also used in the food industry as an emulsifier (E433).
- It is often combined with other emulsifiers to create very stable formulas.
