Ingredient review
PEG-10 Oleamine
INCI: PEG-10 Oleamine
PEG-10 Oleamine is an effective emulsifier but may cause irritation or clog pores for sensitive or acne-prone skin.
In plain English
PEG-10 Oleamine is a synthetic ingredient that helps oil and water mix together in products like cleansers and shampoos. It belongs to a group of chemicals called PEGs (polyethylene glycols) combined with a fatty amine. While it works well to create smooth textures, it can be drying or irritating for some people, especially those with sensitive skin or acne. It's not a natural ingredient and is mostly used in rinse-off products to minimize skin contact.

Quick decision guide
Useful, but context matters
PEG-10 Oleamine can be useful, but watch for some irritation potential and possible clogging concerns.
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 Oleamine.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
Clogging risk
moderateMay be fine for many users but deserves caution if you are breakout-prone.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
PEG-10 Oleamine is a synthetic compound made by reacting oleylamine (a fatty amine derived from oleic acid, a common fatty acid found in oils) with 10 units of ethylene oxide (a petrochemical). This process creates a surfactant that can lower the surface tension between oil and water, allowing them to blend into a stable mixture.
How it works
In a cosmetic product, PEG-10 Oleamine acts as an emulsifier and surfactant. Its structure has a water-loving (hydrophilic) PEG chain and an oil-loving (lipophilic) fatty amine tail. When added to a formula, it positions itself at the interface of oil and water droplets, preventing them from separating and creating a smooth, uniform product. It also helps to lift dirt and oil from the skin or hair, making it useful in cleansers.
Pros
Effective emulsifier
PEG-10 Oleamine reliably blends oil and water, creating stable, smooth formulas that feel pleasant on skin and hair.
Good cleansing power
It helps lift and remove excess oil, dirt, and product buildup, making it useful in shampoos and facial cleansers.
Cons and cautions
Potential irritation
As a surfactant, it can strip the skin's natural oils and cause dryness, redness, or stinging, especially for sensitive skin types.
May clog pores
Some users report breakouts with products containing PEG-10 Oleamine, likely due to its fatty amine component that can be comedogenic for some.
Best for
- People with normal to oily skin looking for effective cleansers
- Those using rinse-off products like shampoos and body washes
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
- Those with acne-prone skin who may experience breakouts
Usage tips
Safety summary
PEG-10 Oleamine is considered safe for use in cosmetics at typical concentrations, but it can cause irritation or clog pores for some individuals. It is best suited for rinse-off products to limit skin exposure. Those with sensitive or acne-prone skin should use caution.
Research notes
Research on PEG-10 Oleamine specifically is limited, but studies on similar PEG surfactants indicate low acute toxicity and moderate skin irritation potential. The Cosmetic Ingredient Review (CIR) has reviewed related PEG compounds and found them safe when formulated to avoid irritation.
Common label clues
- Typical concentration
- Typically 0.5–5% in rinse-off products; lower in leave-on products
- Regulatory status
- Approved for use in cosmetics in the US and EU within regulated concentration limits. The Cosmetic Ingredient Review (CIR) has evaluated related PEG compounds and found them safe when formulated properly.
- Common uses
- Cleansers, Shampoos, Conditioners, Emulsions
- Environmental note
- PEG-10 Oleamine is synthetic and may not be readily biodegradable. Its production involves ethylene oxide, a petrochemical, which raises environmental concerns.
Good to know
- PEG-10 Oleamine is often found in combination with other surfactants to balance cleansing and mildness.
- It is not typically used in high concentrations in leave-on products due to irritation potential.
