Ingredient review
PEG-60 Sorbitan Stearate
INCI: PEG-60 Sorbitan Stearate
A gentle, water-loving emulsifier that helps create stable, non-greasy lotions and creams.
In plain English
PEG-60 Sorbitan Stearate is a semi-synthetic ingredient made by attaching ethylene oxide to sorbitan stearate (a mix of sorbitol and stearic acid). It acts as a bridge between oil and water, allowing them to mix into a smooth, stable cream or lotion. Because it is water-soluble, it rinses off easily and leaves a light, non-greasy feel on the skin. It is considered very gentle and is commonly used in mild cleansers and moisturizers.

Quick decision guide
Useful, but context matters
PEG-60 Sorbitan Stearate 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-60 Sorbitan Stearate.
- 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 polyethylene glycol (PEG) derivative of sorbitan stearate, created through a process called ethoxylation. It is a non-ionic surfactant and emulsifier that is highly water-soluble.
How it works
It reduces the surface tension between oil and water, allowing them to blend into a stable emulsion. In a formula, it helps disperse oils into tiny droplets that stay suspended in water, preventing separation. This creates a smooth, uniform texture that spreads easily and rinses cleanly.
Pros
Gentle emulsifier
PEG-60 Sorbitan Stearate is very mild and unlikely to cause irritation, making it suitable for sensitive skin and daily use.
Lightweight feel
Because it is water-soluble, it rinses cleanly and leaves no heavy or sticky residue, which is ideal for lotions and gel-creams.
Cons and cautions
PEG processing concerns
The ethoxylation process can create trace amounts of 1,4-dioxane, a potential carcinogen. However, reputable manufacturers purify the ingredient to very low levels.
Not for strict 'clean' lists
Some consumers and brands avoid PEG ingredients due to the manufacturing process, even though the finished ingredient is considered safe by regulators.
Best for
- People with normal to combination skin
- Those who prefer lightweight, non-greasy moisturizers and cleansers
Use caution if
- Individuals who strictly avoid PEG-derived ingredients due to personal or environmental concerns
Usage tips
Safety summary
PEG-60 Sorbitan Stearate is considered safe for cosmetic use by major regulatory bodies. The main concern is the potential for trace 1,4-dioxane contamination, but purification steps keep levels well below safety limits. It is non-irritating and non-comedogenic for most skin types.
Research notes
The Cosmetic Ingredient Review (CIR) panel reviewed PEG sorbitan stearates and concluded they are safe in cosmetics. Studies show low irritation and sensitization potential. No significant human or animal toxicity has been reported at cosmetic concentrations.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and the EU Cosmetics Regulation. The Cosmetic Ingredient Review (CIR) panel has deemed it safe as used in rinse-off and leave-on products.
- Common uses
- Cleansers, Moisturizers, Sunscreens, Makeup removers
- Environmental note
- PEG compounds can be slow to biodegrade in aquatic environments. However, PEG-60 Sorbitan Stearate is not classified as a major environmental concern at typical cosmetic use levels.
Good to know
- PEG-60 Sorbitan Stearate is often used in micellar waters and gentle cleansing lotions.
- It is considered safe by the Cosmetic Ingredient Review (CIR) panel at concentrations up to 25%.
