Aminopropyl Laurylglutamine

INCI: Aminopropyl Laurylglutamine

A gentle, amino-acid-based cleanser that effectively removes dirt and oil without stripping the skin, making it ideal for sensitive or dry skin types.

In plain English

Aminopropyl Laurylglutamine is a mild cleansing ingredient made from lauric acid (found in coconut oil) and the amino acid glutamine. It works like a gentle soap that lifts away dirt and excess oil from your skin, but it's much kinder to your skin's protective barrier than traditional harsh detergents like sodium lauryl sulfate. Because it's derived from natural building blocks your skin recognizes, it tends to be very well-tolerated and leaves skin feeling soft rather than tight or dry.

Quick decision guide

Easy yes for most routines

Aminopropyl Laurylglutamine 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 Aminopropyl Laurylglutamine.
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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A semi-synthetic surfactant created by combining lauric acid (a fatty acid from coconut or palm kernel oil) with glutamine (an amino acid naturally present in the skin). The result is a mild, amphiphilic molecule that can attract both water and oil, allowing it to emulsify and rinse away impurities.

How it works

In a cleanser, Aminopropyl Laurylglutamine reduces the surface tension between water and the oils on your skin. This allows the product to surround and lift away dirt, sebum, and makeup so they can be rinsed off with water. Unlike sulfate-based cleansers, it has a larger molecular structure that doesn't penetrate the skin's barrier as easily, which helps prevent irritation and moisture loss.

Pros

Gentle on skin barrier

Because it's derived from amino acids, this surfactant is much less likely to disrupt the skin's protective barrier compared to sulfates, helping to keep moisture in and irritants out.

Low irritation risk

Clinical and anecdotal evidence consistently shows very low rates of stinging, redness, or allergic reactions, making it a top choice for sensitive or compromised skin.

Cons and cautions

Milder lather

It produces a creamy, low-foam lather rather than big, bubbly suds. If you associate foam with cleanliness, you might feel it's not cleansing enough, even though it is.

Higher cost

Amino-acid surfactants are more expensive to produce than conventional detergents, so products containing them often come with a higher price tag.

Best for

People with dry, sensitive, or eczema-prone skin who need a very gentle cleanser
Anyone looking to reduce irritation from daily cleansing while still getting effective dirt and oil removal

Use caution if

Those who prefer a very high-foam, bubbly cleansing experience may find this ingredient too mild

Usage tips

Use lukewarm water, as hot water can reduce the effectiveness of mild surfactants and irritate skin.

Massage gently onto damp skin for about 30–60 seconds before rinsing thoroughly to allow the ingredient to work without over-scrubbing.

Safety summary

Aminopropyl Laurylglutamine is considered very safe for topical use. It has a low irritation and sensitization profile, and no significant toxicity concerns have been reported in cosmetic concentrations. It is not known to be comedogenic.

Research notes

Amino-acid-based surfactants like this one have been studied for their mildness and ability to preserve skin barrier function. Research shows they cause less protein denaturation and lipid extraction compared to traditional anionic surfactants, supporting their use in gentle cleansing formulations.

Common label clues

Typical concentration: 1–10% in rinse-off products
Regulatory status: Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
Common uses: Facial cleansers, Body washes, Shampoos, Micellar waters
Environmental note: Derived from renewable plant sources (coconut/palm) and is biodegradable. However, palm sourcing may raise sustainability concerns unless certified sustainable.

Good to know

Aminopropyl Laurylglutamine is often listed near the middle or end of an ingredient list because it's effective at relatively low concentrations.
It pairs well with other mild surfactants like cocamidopropyl betaine to create a balanced, non-stripping cleanser.
