Ingredient review
PEG-2 Lauramide
INCI: PEG-2 Lauramide
PEG-2 Lauramide is a synthetic ingredient that helps cleansers foam and mix oil with water, but it may be mildly irritating for sensitive skin.
In plain English
PEG-2 Lauramide is a man-made ingredient added to cleansers and shampoos to help them foam up and mix oil and water together. It's a type of surfactant, which means it helps lift dirt and oil from your skin so they can be rinsed away. While effective, it can be slightly drying or irritating for people with very sensitive or dry skin.

Quick decision guide
Useful, but context matters
PEG-2 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-2 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-2 Lauramide is a synthetic compound made by reacting lauric acid (a fatty acid from coconut or palm oil) with ethylene oxide. It belongs to a group of ingredients called alkanolamides, which are used to boost foam and stabilize formulas.
How it works
In a cosmetic product, PEG-2 Lauramide sits at the boundary between oil and water, reducing surface tension so that oils can be broken into tiny droplets and washed away. It also helps create a rich, stable lather in cleansers.
Pros
Effective foaming agent
Creates a rich, satisfying lather that helps spread the product evenly and makes rinsing feel thorough.
Good oil and water mixer
Helps the formula stay stable and prevents separation, so you get a consistent product every time.
Cons and cautions
Potential irritation
For sensitive or damaged skin, PEG-2 Lauramide can cause stinging, redness, or dryness, especially in high concentrations.
Synthetic and not biodegradable
Made from petrochemical or processed plant oils, it may not break down easily in the environment compared to some natural surfactants.
Best for
- People with normal to oily skin looking for effective cleansing
- Those who enjoy a foamy, bubbly cleanser texture
Use caution if
- Individuals with very dry, sensitive, or eczema-prone skin
- Those seeking a completely natural or plant-based routine
Usage tips
Safety summary
PEG-2 Lauramide is considered safe for use in rinse-off cosmetics at typical concentrations. However, it can be mildly irritating for sensitive skin, and the PEG manufacturing process may introduce trace impurities if not properly purified. Overall, it is a low-risk ingredient for most people when used as directed.
Research notes
Studies on alkanolamides like PEG-2 Lauramide show they are effective surfactants with low acute toxicity. Skin irritation potential is moderate, and they are generally well-tolerated in rinse-off products. Long-term safety data is limited but no major concerns have been raised by regulatory bodies.
Common label clues
- Typical concentration
- Typically 0.5–5% 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, Facial washes
- Environmental note
- PEG-2 Lauramide is synthetic and may not be readily biodegradable. Some consumers prefer plant-based, biodegradable alternatives for environmental reasons.
Good to know
- PEG-2 Lauramide is often found in combination with other surfactants to balance cleansing power and mildness.
- The 'PEG' part means it has been processed with ethylene oxide, which can sometimes contain trace impurities like 1,4-dioxane, though reputable manufacturers purify their ingredients.
