Ingredient review
PEG-30 Oleamine
INCI: PEG-30 Oleamine
PEG-30 Oleamine is an effective emulsifier but may cause irritation or clog pores for sensitive or acne-prone skin.
In plain English
PEG-30 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), which are made from petroleum. While it works well to create smooth, stable formulas, it can be drying or irritating for some people, especially if used in high amounts or left on the skin.

Quick decision guide
Useful, but context matters
PEG-30 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-30 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-30 Oleamine is a polyethylene glycol derivative of oleamine (a fatty amine from oleic acid). It is a synthetic surfactant and emulsifier that reduces surface tension between oil and water, allowing them to blend into a stable mixture.
How it works
In a cosmetic product, PEG-30 Oleamine positions itself at the interface of oil and water droplets, lowering surface tension so the two phases can mix. This creates a uniform emulsion (like a lotion or cream) and helps cleanse by lifting dirt and oil from the skin or hair so they can be rinsed away.
Pros
Effective emulsifier
PEG-30 Oleamine reliably blends oil and water, giving products a smooth, uniform texture that feels pleasant to apply.
Good cleansing power
It helps lift and remove excess oil, sebum, and makeup from the skin and hair, making it useful in rinse-off cleansers.
Cons and cautions
Potential irritation
This ingredient can be drying or irritating, especially for those with sensitive skin or when used in high concentrations in leave-on products.
Moderate comedogenic risk
Some users may find it clogs pores, leading to breakouts, particularly if the product is not thoroughly rinsed off.
Best for
- People with normal to oily skin looking for effective cleansers
- Those who tolerate synthetic surfactants well
Use caution if
- Individuals with very dry, sensitive, or eczema-prone skin
Usage tips
Safety summary
PEG-30 Oleamine is considered safe for use in cosmetics at typical concentrations, but it can cause irritation or dryness in sensitive individuals. The main concern is potential contamination with 1,4-dioxane, though levels are regulated and generally low in finished products.
Research notes
Studies on PEG derivatives indicate low acute toxicity and skin sensitization potential, but irritation can occur at higher concentrations. The Cosmetic Ingredient Review has concluded that PEGs are safe as used in cosmetics when formulated to minimize 1,4-dioxane.
Common label clues
- Typical concentration
- Usually 0.5% to 5% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions, with concentration limits in some countries. The Cosmetic Ingredient Review (CIR) panel has reviewed PEG derivatives and found them safe when formulated properly.
- Common uses
- Cleansers, Shampoos, Conditioners, Emulsions
- Environmental note
- PEG-30 Oleamine is synthetic and derived from petroleum, so it is not biodegradable in all conditions. It may contribute to aquatic toxicity if washed down drains in large amounts.
Good to know
- PEG-30 Oleamine is often found in professional hair care and some facial cleansers.
- The 'PEG' part means it may contain trace levels of 1,4-dioxane, a byproduct, but reputable manufacturers purify to keep levels very low.
