What Is Sodium Lauroyl Glutamate?
Sodium Lauroyl Glutamate (SLG) is a premium amino-acid-based anionic surfactant synthesized from plant-origin lauric acid and natural L-glutamic acid. Commercial cosmetic-grade SLG-30 is a colourless to pale-yellow transparent liquid with 28-32% active content.
It delivers moderate cleansing power together with fine, dense creamy foam. Its amino-acid molecular structure grants exceptional skin compatibility. Unlike harsh sulfate surfactants, it avoids over-stripping skin lipid barrier; after rinsing, it leaves skin soft and smooth without tight-dry sensation. It can be used as primary surfactant for pure amino-acid cleansing products, or added as co-surfactant to reduce overall irritation of other surfactant blends. It features excellent biodegradability and fits clean-beauty, sensitive-skin and infant-safe cosmetic concepts.
Different from SLES (sulfate-type anionic surfactant), Sodium Lauroyl Glutamate is amino-acid structured, far lower irritation, skin-friendly post-wash feel, though foam volume is lower than SLES. Different from CAPB amphoteric surfactant, SLG belongs to anionic surfactant with better foaming performance when used as main cleanser. Aogebio supplies high-purity cosmetic-grade Sodium Lauroyl Glutamate in bulk, offering free samples, full qualification documents and global one-stop shipping services for cosmetic manufacturers.
Core Advantages Of Our Sodium Lauroyl Glutamate
Natural-Derived Amino-Acid Surfactant & High-Purity Refined
Adopts green peptide-condensation synthesis and multi-step purification process, low impurity and low salt content, faint neutral odor, meets clean-beauty and natural cosmetic raw-material requirements, suitable for high-end skincare product development.
Ultra-Mild & Barrier-Friendly Cleansing Performance
Amino-acid molecular structure, low skin & eye irritation. Effectively removes dirt, excess sebum and light makeup residue without destroying skin acid mantle. Ideal choice for sensitive-skin, barrier-damaged skin and baby-care cleansing formulas.
Fine Creamy Foam & Pleasant Post-Wash Skin-Feel
Produces delicate, dense creamy foam; no large-volume coarse foam. After rinsing, skin remains soft and moisturized, eliminates the tight-dry feeling common with sulfate-based cleansers.
Excellent Surfactant Synergistic Compatibility
Perfectly compatible with anionic, amphoteric, non-ionic surfactants. When compounded with SLES, CAPB, APG surfactants, it can significantly lower formula irritation and optimize foam texture and sensory experience.
Broad pH Stability & Good Hard-Water Resistance
Stable performance over wide pH range; maintains good foaming and cleansing effect under hard-water condition, less affected by mineral ions in tap-water.
High Biodegradability & Eco-Friendly
Rapid biodegradation in natural environment, low aquatic toxicity, matches the formulation demand of environmentally-friendly personal-care products.
Stable Batch Quality & Flexible Supply
Consistent batch-to-batch active content, foam performance and physical-chemical indicators, fit for large-scale industrial production; support sample testing, small-batch trial order and large-volume bulk customization.
How Sodium Lauroyl Glutamate Works In Cosmetic Formulations
Sodium Lauroyl Glutamate molecules consist of lipophilic lauric-acid alkyl tail and hydrophilic amino-acid carboxylate head-group. In aqueous cleansing system, surfactant molecules assemble at oil-water interface to form micelle structures, wrapping sebum, dirt and particulate contaminants, which are washed away during rinsing.
Its amino-acid polar group has high affinity with skin keratin protein, will not excessively extract skin surface lipid. When compounded with other surfactants, mixed micelles are formed to weaken the aggressive stimulation of strong surfactants, improving the mildness of the whole system. It is suitable for various rinse-off formulas; finished product pH should be adjusted to skin-friendly 5.5-6.5 range with citric acid for optimal use experience.
Main Functions & Cosmetic Application Fields
Core Functional Benefits
- • Ultra-mild amino-acid cleansing agent: remove dirt and sebum without damaging skin barrier

Formulation Guide: Dosage, Solubility & Matching Tips
Recommended dosage (calculated based on commercial SLG-30 30% active raw liquid):
- -Amino-acid facial cleanser (as primary surfactant): 15%-45%
- -Shampoo & hair-care cleansing product: 8%-30%
- -Body wash / shower gel: 5%-25%
- -Baby & sensitive-skin cleansing formula (co-surfactant): 2%-10%
Solubility: Fully soluble in water phase; insoluble in oil phase, add into water-phase under stirring during production.
Recommended matching ingredients: Cocamidopropyl Betaine(CAPB), Decyl Glucoside, Coco-Glucoside, SLES, glycerin, panthenol, citric acid (pH adjuster), sodium chloride (partial viscosity adjustment).
Formulation Notes:
- -Raw material is weakly alkaline. After formula mixing, adjust finished-product pH to skin-friendly 5.5-6.5 with citric acid or lactic acid for best mildness and foam performance.
- -Processing temperature suggested ≤75℃; avoid long-time high-temperature heating to prevent color deepening and performance decline.
- -When used as primary surfactant, match with co-surfactants such as CAPB or APG to enrich foam volume.
- -Salt-thickening effect is limited; for high-viscosity requirement, combine with polymer thickeners.
- -Seal and store under cool-dry condition; avoid direct sunlight and high-temperature storage to prevent discoloration.

Frequently Asked Questions
-
Q1: What is the difference between Sodium Lauroyl Glutamate and SLES?
A: Sodium Lauroyl Glutamate is amino-acid-based anionic surfactant, ultra-low irritation, soft non-tight post-wash skin-feel, fine creamy foam. SLES is sulfate-type anionic surfactant, high-foam volume, stronger degreasing power, relatively higher irritation. SLG is core raw-material for high-end sulfate-free amino-acid cleansing products. -
