Ingredient review
PEG-7 Oleamide
INCI: PEG-7 Oleamide
PEG-7 Oleamide is a gentle synthetic emulsifier that helps blend oil and water in cleansers and lotions, but its PEG component raises mild environmental concerns.
In plain English
PEG-7 Oleamide is a lab-made ingredient that helps oil and water mix together in products like cleansers and lotions. It also helps create a nice, creamy texture and can boost the foaming action of cleansers. The 'PEG' part means it's processed with ethylene oxide, which some people prefer to avoid due to potential trace impurities, though cosmetic-grade versions are purified.

Quick decision guide
Useful, but context matters
PEG-7 Oleamide 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-7 Oleamide.
- 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-7 Oleamide is a synthetic compound formed by reacting oleic acid (a fatty acid from oils) with ethylene oxide. It belongs to the PEG (polyethylene glycol) family and acts as a surfactant and emulsifier.
How it works
In a cosmetic product, PEG-7 Oleamide reduces the surface tension between oil and water, allowing them to blend into a stable emulsion. It also helps disperse ingredients evenly and can improve the foaming and cleansing properties of wash-off products.
Pros
Effective emulsifier
Helps oil and water mix smoothly, giving lotions and cleansers a consistent, pleasant texture without separation.
Gentle surfactant
Provides mild cleansing and foaming, making it suitable for daily use in shampoos and body washes without stripping the skin.
Cons and cautions
PEG-related impurity concern
During manufacturing, trace amounts of 1,4-dioxane can form. Cosmetic-grade PEGs are purified to safe levels, but some consumers prefer to avoid PEGs entirely.
Not biodegradable
PEG-7 Oleamide is not readily biodegradable, which may be a concern for environmentally conscious users looking for eco-friendly options.
Best for
- People using standard cleansers and lotions who want a stable, creamy texture
- Those with normal to oily skin looking for gentle cleansing
Use caution if
- Individuals with known sensitivities to PEG compounds or ethylene oxide derivatives
- Those seeking fully biodegradable or natural formulations
Usage tips
Safety summary
PEG-7 Oleamide is considered safe for cosmetic use at typical concentrations. The main concern is potential trace contamination with 1,4-dioxane, but cosmetic-grade ingredients are purified to meet safety standards. It has low irritation and comedogenic risk.
Research notes
Research on PEG-7 Oleamide specifically is limited, but PEG compounds in general have been reviewed by safety panels (e.g., CIR) and deemed safe for use in cosmetics when properly purified. Studies focus on impurity control rather than direct skin effects.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database, with concentration limits for PEG compounds to ensure safety.
- Common uses
- Cleansers, Shampoos, Body washes, Lotions
- Environmental note
- PEG-7 Oleamide is not readily biodegradable and may accumulate in aquatic environments, though it is used in low concentrations in rinse-off products.
Good to know
- PEG-7 Oleamide is often used in combination with other emulsifiers to improve stability.
- The number '7' refers to the average number of ethylene oxide units, which affects its water solubility and mildness.
