Ingredient review
PEG-15 Oleamine
INCI: PEG-15 Oleamine
PEG-15 Oleamine is a synthetic emulsifier that helps mix oil and water, but it may be irritating for sensitive skin and has moderate comedogenic potential.
In plain English
PEG-15 Oleamine is a man-made ingredient that helps oil and water stay mixed together in products like cleansers and shampoos. It belongs to a group of chemicals called PEGs (polyethylene glycols), which are often used to improve texture and cleaning power. While effective, it can be drying or irritating for some people, especially those with sensitive or acne-prone skin.

Quick decision guide
Useful, but context matters
PEG-15 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-15 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-15 Oleamine is a synthetic compound created by reacting oleic acid (a fatty acid from oils) with ethylene oxide. It acts as a surfactant and emulsifier, meaning it helps water and oil blend and helps remove dirt and oil from skin or hair.
How it works
In a cosmetic product, PEG-15 Oleamine reduces the surface tension between oil and water, allowing them to form a stable mixture. This helps cleansers lift away sebum and makeup, and improves the texture and spreadability of creams and lotions.
Pros
Effective emulsifier
Helps create stable, well-mixed formulas so products feel smooth and work consistently.
Good for oily skin
Its surfactant properties help break down excess sebum and makeup, making it useful in cleansers for oily skin types.
Cons and cautions
Potential irritation
Can strip natural oils and cause dryness or stinging, especially for sensitive or compromised skin barriers.
Moderate comedogenic risk
May clog pores for some people, so those prone to breakouts should patch test before using regularly.
Best for
- People with normal to oily skin looking for effective cleansing
- Those using rinse-off products like shampoos and body washes
Use caution if
- Individuals with very dry, sensitive, or eczema-prone skin
- Anyone who finds PEG-based ingredients irritating
Usage tips
Safety summary
PEG-15 Oleamine is considered safe in rinse-off products at typical concentrations, but it may cause irritation or dryness in sensitive individuals. Regulatory bodies set limits on potential contaminants like 1,4-dioxane to ensure safety.
Research notes
Studies on PEG oleamines are limited, but the Cosmetic Ingredient Review (CIR) panel has evaluated similar PEG surfactants and found them safe when formulated properly. Most evidence comes from industry safety assessments rather than independent clinical trials.
Common label clues
- Typical concentration
- Usually 0.5% to 5% of the formula
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) with concentration limits for impurities like 1,4-dioxane.
- Common uses
- Cleansers, Shampoos, Conditioners, Facial washes
- Environmental note
- PEG compounds are generally biodegradable, but their production involves ethylene oxide, which is derived from fossil fuels.
Good to know
- PEG-15 Oleamine is often found in clarifying shampoos and oil-control cleansers.
- The number '15' refers to the average number of ethylene oxide units, which affects its solubility and mildness.
