Ingredient review
PEG-2 Sorbitan Trioleate
INCI: PEG-2 Sorbitan Trioleate
A gentle synthetic emulsifier that helps mix water and oil in creams and lotions, generally well-tolerated by most skin types.
In plain English
PEG-2 Sorbitan Trioleate is a man-made ingredient that acts like a bridge between water and oil. In a moisturizer or cleanser, it keeps the formula from separating into layers, so you get a smooth, consistent product every time you use it. It's part of a family of PEG (polyethylene glycol) compounds, which are widely used in cosmetics for their mildness and stability.

Quick decision guide
Useful, but context matters
PEG-2 Sorbitan Trioleate 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-2 Sorbitan Trioleate.
- 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
PEG-2 Sorbitan Trioleate is a synthetic emulsifier derived from sorbitol (a sugar alcohol) and oleic acid (a fatty acid from oils), modified with a small PEG chain. It belongs to the sorbitan ester family and is designed to stabilize oil-in-water emulsions.
How it works
In a cosmetic formula, PEG-2 Sorbitan Trioleate positions itself at the boundary between oil and water droplets. Its water-loving (hydrophilic) PEG chain faces the water, while its oil-loving (lipophilic) fatty acid tail faces the oil. This reduces surface tension and prevents the two phases from separating, giving the product a uniform texture and feel.
Pros
Gentle emulsifier
PEG-2 Sorbitan Trioleate is considered low-irritation and suitable for most skin types, including sensitive skin, when used at typical concentrations.
Improves product texture
It helps create smooth, non-greasy creams and lotions that spread easily and feel pleasant on the skin.
Cons and cautions
Synthetic origin
It is a man-made ingredient, which may not appeal to those seeking natural or organic skincare products.
Environmental concerns
PEG compounds can be slow to biodegrade, and their production involves ethylene oxide, which has manufacturing safety considerations.
Best for
- People with normal to dry skin looking for stable moisturizers
- Those who prefer synthetic emulsifiers over natural waxes
Use caution if
- Individuals with known sensitivities to PEG compounds (rare)
- Those seeking 100% natural or organic formulations
Usage tips
Safety summary
PEG-2 Sorbitan Trioleate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential. Regulatory bodies like the Cosmetic Ingredient Review (CIR) have evaluated similar PEG sorbitan esters and found them safe as used.
Research notes
Research on PEG sorbitan esters indicates they are mild surfactants with low acute toxicity. Studies show they do not accumulate in the body and are well-tolerated on skin. The evidence supports their safety in leave-on and rinse-off products.
Common label clues
- Typical concentration
- Typically 0.5% to 5% of the formula
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no specific concentration restrictions, though manufacturers follow good manufacturing practices.
- Common uses
- Moisturizers, Cleansers, Sunscreens, Makeup removers
- Environmental note
- PEG compounds are not readily biodegradable in all conditions, but they are used in low concentrations and are generally considered low-risk in rinse-off products.
Good to know
- PEG-2 Sorbitan Trioleate is often used in combination with other emulsifiers to achieve the perfect texture.
- The 'PEG-2' indicates a short chain length, which generally means lower penetration and milder action.
