Ingredient review
PEG-10 Glyceryl Oleate
INCI: PEG-10 Glyceryl Oleate
A gentle emulsifier that helps mix oil and water in cleansers and creams, generally well-tolerated by most skin types.
In plain English
PEG-10 Glyceryl Oleate is a helper ingredient that allows oil and water to blend together in products like cleansers and lotions. It is made by attaching a small chain of PEG (polyethylene glycol) to glyceryl oleate, a natural fat derived from vegetable oils. This makes it a mild surfactant that can gently lift dirt and makeup without stripping the skin.

Quick decision guide
Useful, but context matters
PEG-10 Glyceryl Oleate 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-10 Glyceryl Oleate.
- 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-10 Glyceryl Oleate is a semi-synthetic emulsifier created by reacting ethylene oxide with glyceryl oleate. It belongs to the PEG (polyethylene glycol) family and is used to stabilize oil-in-water emulsions.
How it works
In a cosmetic product, PEG-10 Glyceryl Oleate sits at the boundary between oil and water droplets, reducing surface tension so they stay mixed. This creates a smooth, uniform texture and helps the product spread easily. In cleansers, it also helps break down oils and dirt so they can be rinsed away.
Pros
Gentle on skin
Unlike harsher sulfates, PEG-10 Glyceryl Oleate cleanses without stripping the skin's natural moisture barrier, making it suitable for daily use.
Versatile formulator
It works well in both rinse-off and leave-on products, helping create smooth, stable textures in creams, lotions, and cleansers.
Cons and cautions
Potential contamination risk
As a PEG compound, it may contain trace impurities like 1,4-dioxane if not properly purified, though reputable brands ensure low levels.
Not natural
It is semi-synthetic, so it may not appeal to those seeking fully natural or organic skincare ingredients.
Best for
- People with normal to dry skin looking for gentle cleansers
- Anyone who prefers mild, non-stripping surfactants in their routine
Use caution if
- Those with known sensitivities to PEG compounds (rare)
- Individuals seeking completely natural or PEG-free formulations
Usage tips
Safety summary
PEG-10 Glyceryl Oleate is considered safe for use in cosmetics at typical concentrations. The main safety concern is potential contamination with 1,4-dioxane, but this is tightly regulated and monitored by manufacturers. It is non-irritating and non-comedogenic for most skin types.
Research notes
The Cosmetic Ingredient Review (CIR) panel has evaluated PEG compounds and found them safe as used in cosmetics. Studies show low irritation and sensitization potential. No significant research specifically on PEG-10 Glyceryl Oleate exists, but it is grouped with similar PEG glyceryl esters.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database, with no concentration restrictions for leave-on or rinse-off products.
- Common uses
- Cleansers, Lotions, Creams, Makeup removers
- Environmental note
- PEG compounds are generally biodegradable, but their production involves ethylene oxide, which is derived from fossil fuels.
Good to know
- PEG-10 Glyceryl Oleate is often found in 'milky' cleansers and lightweight lotions.
- The number '10' refers to the average length of the PEG chain, which affects its water solubility.
