Ingredient review
PEG-120 Methyl Glucose Trioleate
INCI: PEG-120 Methyl Glucose Trioleate
A mild, non-stripping cleanser that helps create a rich lather without drying out the skin.
In plain English
PEG-120 Methyl Glucose Trioleate is a gentle cleansing ingredient made from glucose (a sugar) and oleic acid (a fatty acid found in olive oil). It helps cleansers foam up nicely while being very mild on the skin, so it won't strip away your natural oils or cause irritation. You'll often find it in sulfate-free shampoos and creamy facial cleansers.

Quick decision guide
Easy yes for most routines
PEG-120 Methyl Glucose 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-120 Methyl Glucose 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
A semi-synthetic polymer derived from methyl glucose (a sugar derivative) and trioleate (a fatty acid from oleic acid). It is modified with PEG (polyethylene glycol) to make it water-soluble and improve its cleansing and thickening properties.
How it works
It works as a surfactant, meaning it helps water mix with oil and dirt so they can be rinsed away. Its large molecular structure makes it too big to penetrate the skin deeply, so it stays on the surface and gently lifts impurities without disrupting the skin barrier. It also thickens the product, giving it a luxurious, creamy texture.
Pros
Extremely gentle
Unlike harsh sulfates, this ingredient cleans without stripping the skin's natural moisture barrier, making it ideal for daily use on sensitive or dry skin.
Rich texture
It gives cleansers a creamy, luxurious feel that many users find more pleasant than watery or runny formulas.
Cons and cautions
Lower foam
It produces a softer, creamier lather rather than big bubbles, which may not satisfy those who equate foam with cleanliness.
Potential residue
On fine or oily hair, it can sometimes leave a slight film if not rinsed thoroughly, though this is rare.
Best for
- People with dry or sensitive skin
- Those looking for a sulfate-free cleanser
- Anyone who wants a gentle, non-stripping face wash
Use caution if
- Those who prefer very high-foaming cleansers
- Individuals with known PEG sensitivity (rare)
