Ingredient review
Lysine Lauroyl Glutamate
INCI: LYSINE LAUROYL GLUTAMATE
A gentle, amino-acid-based surfactant that cleanses without stripping the skin, making it ideal for sensitive and dry skin types.
In plain English
Lysine Lauroyl Glutamate is a mild cleansing ingredient made by combining the amino acids lysine and glutamic acid with lauric acid (from coconut oil). It helps remove dirt, oil, and makeup without disrupting the skin's natural moisture barrier. Unlike harsher sulfates, it leaves skin feeling soft and comfortable, not tight or dry.

Quick decision guide
Easy yes for most routines
Lysine 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 Lysine 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 semi-synthetic surfactant derived from natural amino acids (lysine and glutamic acid) and lauric acid, a fatty acid found in coconut oil. It belongs to the class of acyl amino acid surfactants known for their mildness and compatibility with sensitive skin.
How it works
In a cosmetic product, Lysine Lauroyl Glutamate reduces the surface tension between water and oil, allowing impurities to be lifted away and rinsed off. Its molecular structure is similar to natural skin components, so it cleanses gently without over-stripping the skin's protective barrier.
Pros
Gentle on skin
Its amino-acid structure closely mimics the skin's natural proteins, reducing the risk of irritation and dryness even with frequent use.
Maintains moisture barrier
Unlike harsh detergents, it cleanses without stripping essential lipids, helping the skin retain hydration and feel comfortable after washing.
Cons and cautions
Lower foaming action
Produces a creamy, low foam that some users may perceive as less effective, though it still cleanses thoroughly.
Higher cost
As a specialty amino-acid surfactant, it is more expensive to produce, which can increase the price of finished products.
Best for
- People with dry, sensitive, or reactive skin
- Those looking for a sulfate-free, gentle cleanser
Use caution if
- Individuals seeking a high-foaming, deep-cleansing experience may prefer stronger surfactants
Usage tips
Safety summary
Lysine Lauroyl Glutamate is considered safe for use in cosmetics. It has a low irritation and comedogenic risk, and no significant safety concerns have been reported in scientific literature or regulatory reviews.
Research notes
Amino-acid-based surfactants like Lysine Lauroyl Glutamate are well-studied for their mildness and skin compatibility. While specific clinical trials on this exact compound are limited, the broader class is supported by dermatological research showing reduced irritation compared to traditional surfactants.
Common label clues
- Typical concentration
- 1–15% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No known restrictions at typical usage levels.
- Common uses
- Facial cleansers, Shampoos, Body washes, Micellar waters
- Environmental note
- Biodegradable and derived from renewable plant-based sources (coconut oil and fermented amino acids), making it a more sustainable choice compared to some petroleum-based surfactants.
Good to know
- Lysine Lauroyl Glutamate is often listed near the top of ingredient lists in sulfate-free cleansers.
- It is compatible with a wide pH range (5.5–7.0), making it easy to formulate into balanced, skin-friendly products.
