Sodium Lauroyl Glutamate | Amino-Acid Cleanser

What Is Sodium Lauroyl Glutamate

Sodium Lauroyl Glutamate (SLG) is a sulfate-free, amino-acid–based anionic surfactant derived from L-glutamic acid and lauroyl (C12) fatty acid. Celebrated for its ultra-mild cleanse, silky slip, and skin-friendly pH, SLG creates a refined, creamy lather that rinses clean without a tight feel. It shines in shampoo bars, gel/cream cleansers, and body washes, and it pairs beautifully with amphoterics to deliver everyday gentleness for scalp and skin—especially in low-pH systems.

Balanced foam, scalp-friendly pH, and everyday comfort.

What is Sodium Lauroyl Glutamate?

It’s a mild, sulfate-free anionic surfactant made by combining lauric acid (often coconut/palm-derived) with the amino acid L-glutamic acid. It lifts dirt and oil while staying gentle on skin and hair.

Why does Seek Bamboo use it instead of SLS/SLES?

Compared with SLS/SLES, Sodium Lauroyl Glutamate (SLG) shows lower irritation, a softer, creamier foam, and a more conditioned after-feel—so formulas can cleanse effectively without the squeaky dryness.

Is Sodium Lauroyl Glutamate safe for sensitive skin?

Yes. SLG is known for low irritation and is widely used in gentle face washes, baby cleansers, and daily shampoos. As always, patch test if you’re very reactive.

What does it do in shampoo and body wash?

It provides creamy foam, effective yet mild cleansing, and helps keep the cuticle/skin barrier comfortable. Hair feels clean but not stripped, which supports shine and manageability.

How does it compare to Sodium Cocoyl Isethionate (SCI) and Sodium Lauroyl Sarcosinate (SLSaR)?

SLG: very gentle, great in low-to-neutral pH liquids, creamy foam.
SCI: ultra-mild solid surfactant for bars; dense, luxurious lather.
Lauroyl Sarcosinate: mild with bouncy foam and good slip.

Is it color-safe and curl-friendly?

Yes. Because it’s less stripping, SLG helps reduce mechanical color fade and keeps curls feeling soft and defined—especially when paired with conditioning polymers.

Does Sodium Lauroyl Glutamate foam well?

Yes—expect fine, creamy foam that rinses easily. Foam quality improves further when blended with amphoterics like Cocamidopropyl Betaine.

Will it dry out my skin?

It’s designed to minimize lipid removal versus harsher detergents. In well-balanced formulas with humectants (glycerin, aloe) and emollients, SLG leaves skin comfortable, not tight.

Is it good for oily or acne-prone skin?

Yes. SLG cleans effectively without over-stripping (which can trigger rebound oil). Pair with niacinamide, zinc PCA, or willow bark/salicylic in separate steps for targeted clarity.

Hard-water performance and buildup?

SLG has good hard-water tolerance and rinses cleanly. If you use many stylers or live in very hard water, rotate an occasional chelating/clarifying wash.
