Ingredient review
Polysorbate 65
INCI: Polysorbate 65
Polysorbate 65 is a gentle emulsifier that keeps oil and water mixed in creams and lotions, with a very low risk of irritation or clogged pores.
In plain English
Polysorbate 65 is a helper ingredient that acts like a bridge between oil and water. In a moisturizer or sunscreen, it stops the formula from separating into an oily layer and a watery layer. It is made from sorbitol (a sugar alcohol) and stearic acid (a fatty acid found in cocoa butter and shea butter), so it is considered mild and well-tolerated by most skin types.

Quick decision guide
Useful, but context matters
Polysorbate 65 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 65.
- 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 65 is a semi-synthetic emulsifier derived from sorbitol and stearic acid. It belongs to the polysorbate family, which are widely used in cosmetics and food to blend oil and water phases into a stable, uniform product.
How it works
Polysorbate 65 has both water-loving (hydrophilic) and oil-loving (lipophilic) parts. When added to a formula, it positions itself at the boundary between oil droplets and water, reducing surface tension and preventing the two from separating. This creates a smooth, consistent texture that stays mixed over time.
Pros
Gentle on skin
Polysorbate 65 has a very low irritation score, making it a safe choice for sensitive skin types and daily-use products.
Effective stabilizer
It reliably prevents oil and water from separating, so your lotion or cream stays smooth and consistent from first use to last.
Cons and cautions
Semi-synthetic origin
It is not a fully natural ingredient, which may be a concern for those seeking 100% natural or organic formulations.
Potential drying in high amounts
In rinse-off cleansers, high concentrations can strip some natural oils, though this is rare at typical usage levels.
Best for
- Anyone using oil-and-water blend products like moisturizers or sunscreens
- People with sensitive or reactive skin who need a gentle emulsifier
Use caution if
- Those seeking exclusively natural or plant-derived ingredients (Polysorbate 65 is semi-synthetic)
Usage tips
Safety summary
Polysorbate 65 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and is well-tolerated by most skin types. The Cosmetic Ingredient Review (CIR) panel has reviewed polysorbates and found them safe as used.
Research notes
Polysorbate 65 has been evaluated by the Cosmetic Ingredient Review (CIR) panel and is considered safe in cosmetic formulations. Studies show it has low acute toxicity and is not a significant skin irritant or sensitizer. Its safety profile is similar to other polysorbates like Polysorbate 20 and 80.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. It is also a permitted food additive (E435) in the EU.
- Common uses
- Moisturizers, Sunscreens, Makeup removers, Lotions, Creams
- Environmental note
- Polysorbate 65 is biodegradable, but its production may involve palm oil, so look for sustainably sourced versions if environmental impact is a concern.
Good to know
- Polysorbate 65 is also used in the food industry as an emulsifier (E435).
- It is often combined with other emulsifiers like cetearyl alcohol for better stability.
