Ingredient review
Arginine Lauroyl Glutamate
INCI: ARGININE LAUROYL GLUTAMATE
A mild, amino-acid-based cleanser that effectively removes dirt and oil while respecting the skin barrier.
In plain English
Arginine Lauroyl Glutamate is a gentle cleansing ingredient made by combining lauric acid (from coconut or palm oil) with the amino acids arginine and glutamic acid. Unlike harsh soaps that can strip your skin of its natural oils, this surfactant cleans without leaving your face feeling tight or dry. It's often used in sulfate-free cleansers and is well-tolerated by sensitive skin types.
Quick decision guide
Easy yes for most routines
Arginine Lauroyl Glutamate 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 Arginine Lauroyl Glutamate.
- 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
A mild, anionic surfactant derived from lauric acid (a fatty acid found in coconut or palm oil) and the amino acids arginine and glutamic acid. It belongs to the family of amino acid-based cleansers, known for their gentle cleansing properties.
How it works
In a cosmetic product, Arginine Lauroyl Glutamate works by reducing the surface tension between water and oil, allowing dirt, sebum, and makeup to be rinsed away. Its molecular structure includes a water-loving (hydrophilic) head and an oil-loving (lipophilic) tail, which helps lift impurities from the skin. Because it has a pH close to that of healthy skin (around 5.5), it cleanses without disrupting the skin's acid mantle.
Pros
Extremely gentle on skin
Unlike harsh sulfates, this surfactant cleanses without stripping the skin's natural moisture barrier, making it ideal for daily use on sensitive or dry skin.
pH-balanced formula
It naturally has a pH close to that of healthy skin (around 5.5), so it helps maintain the skin's acid mantle and reduces the risk of irritation or tightness after washing.
Cons and cautions
May not remove heavy makeup alone
For waterproof or long-wear makeup, you may need an oil-based pre-cleanse or a more robust surfactant blend, as this ingredient is very mild.
Higher cost
Amino acid surfactants are more expensive to produce than conventional sulfates, which can make products containing them pricier.
Best for
- People with dry, sensitive, or eczema-prone skin looking for a gentle cleanser
- Anyone seeking a sulfate-free, amino-acid-based cleanser for daily use
Use caution if
- Those with a known allergy to coconut or palm oil derivatives (rare)
Usage tips
Safety summary
