Ingredient review
PEG-5 Lauramide
INCI: PEG-5 Lauramide
PEG-5 Lauramide is a synthetic emulsifier that helps cleansers foam and mix oil with water, but it may cause mild irritation for sensitive skin.
In plain English
PEG-5 Lauramide is a man-made ingredient that helps oil and water stay mixed together in products like face washes and shampoos. It also helps create a foamy lather. Think of it as a helper that makes cleansers work better, but it can be a bit harsh if your skin is easily irritated.

Quick decision guide
Useful, but context matters
PEG-5 Lauramide can be useful, but watch for some irritation potential.
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-5 Lauramide.
- 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
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-5 Lauramide is a polyethylene glycol (PEG) derivative of lauramide, a fatty acid from coconut or palm oil. It belongs to a class of surfactants that reduce surface tension, allowing water and oil to blend.
How it works
In a cosmetic product, PEG-5 Lauramide sits at the boundary between oil and water droplets, stabilizing the mixture so the product doesn't separate. It also lowers the surface tension of water, which helps create foam and lifts dirt and oil from the skin or hair.
Pros
Effective emulsifier
Helps oil and water blend smoothly, giving cleansers a stable, uniform texture that works well.
Boosts foaming
Creates a rich lather that many people associate with a satisfying clean, especially in shampoos and body washes.
Cons and cautions
Potential irritation
For sensitive or damaged skin, this ingredient can strip natural oils and cause tightness or redness after use.
Manufacturing concerns
As a PEG compound, it may contain trace impurities like 1,4-dioxane if not properly purified, though reputable brands ensure safety.
Best for
- People with normal to oily skin looking for effective cleansing
- Those who use rinse-off products like shampoos and body washes
Use caution if
- Individuals with very dry, sensitive, or eczema-prone skin
Usage tips
Safety summary
PEG-5 Lauramide is considered safe for most people in rinse-off cosmetics at typical concentrations. However, it can be mildly irritating for sensitive skin, and there are minor concerns about potential impurities in PEG ingredients. Regulatory bodies like the Cosmetic Ingredient Review (CIR) have reviewed similar PEG compounds and found them safe when formulated properly.
Research notes
Research on PEG-5 Lauramide specifically is limited, but studies on similar PEG surfactants indicate low acute toxicity and moderate skin irritation potential. The CIR has evaluated related PEG lauramides and concluded they are safe in rinse-off products at concentrations up to 5%.
Common label clues
- Typical concentration
- Typically used at 1–5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions, with concentration limits typically set by good manufacturing practices.
- Common uses
- Cleansers, Shampoos, Body washes, Creams
- Environmental note
- Derived from petrochemicals or plant-based fatty acids; biodegradability varies, and PEG compounds can persist in water systems if not treated.
Good to know
- PEG-5 Lauramide is often found in combination with other mild surfactants to reduce irritation.
- The number '5' refers to the average number of ethylene oxide units, which affects its water solubility and mildness.
