Ingredient review
PEG-3 Lauramine Oxide
INCI: PEG-3 Lauramine Oxide
A gentle cleansing agent that helps create rich foam without stripping the skin, but may cause mild irritation for very sensitive types.
In plain English
PEG-3 Lauramine Oxide is a synthetic ingredient that helps cleansers foam up nicely and feel less harsh. It works by lowering the surface tension of water so dirt and oil can be rinsed away. Think of it as a helper that makes your shampoo or face wash lather better while being kinder to your skin than some stronger detergents.

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-3 Lauramine Oxide.
- 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-3 Lauramine Oxide is a surfactant derived from lauric acid (a fatty acid found in coconut oil) combined with ethylene oxide and an amine oxide group. It is a clear or slightly yellow liquid used primarily in rinse-off cleansing products.
How it works
It reduces the surface tension between water and oil, allowing the product to lift dirt, sebum, and makeup from the skin or hair. Its amine oxide structure also helps stabilize foam, giving a rich, creamy lather that feels luxurious during cleansing.
Pros
Gentle on skin
Compared to harsher surfactants like SLS, PEG-3 Lauramine Oxide is less likely to strip the skin's moisture barrier, making it suitable for daily use.
Improves product feel
It creates a dense, creamy foam that many users find pleasant and effective for a satisfying cleanse.
Cons and cautions
Potential irritant for sensitive skin
Although generally mild, some individuals with very reactive skin may experience slight stinging or redness, especially with prolonged contact.
Synthetic origin
It is manufactured through chemical processes, which may be a drawback for those preferring naturally derived ingredients.
Best for
- People with normal to combination skin
- Anyone who enjoys a foamy cleanser without excessive dryness
Use caution if
- Individuals with known sensitivity to amine oxides
- Those seeking 100% natural or organic formulations
Usage tips
Safety summary
PEG-3 Lauramine Oxide is considered safe for use in rinse-off cosmetics at typical concentrations. It has low acute toxicity and is not a known sensitizer, though mild irritation is possible for very sensitive individuals.
Research notes
Studies indicate that amine oxides like PEG-3 Lauramine Oxide are effective mild surfactants with good foaming properties. Safety reviews by the Cosmetic Ingredient Review (CIR) panel have concluded they are safe when formulated to be non-irritating.
Common label clues
- Typical concentration
- 1–5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database with no specific restrictions at typical concentrations.
- Common uses
