Sodium Lauroyl Glutamate 95% Powder: A Gentle, Science-Backed Cosmetic Surfactant

What Is Sodium Lauroyl Glutamate 95% Powder?

Sodium lauroyl glutamate (SLG) 95% powder is a premium, amino acid-derived anionic surfactant widely used in personal care and cosmetic formulations. Also known as N-lauroyl-L-glutamate monosodium salt, this raw material features a hydrophilic amino acid backbone and a hydrophobic lauryl chain, delivering balanced cleansing, foaming, and skin-conditioning benefits. With a guaranteed purity of 95%, it stands as a cost-effective, high-performance alternative to harsh synthetic surfactants, meeting strict cosmetic grade safety and quality standards.

Derived from natural L-glutamic acid (fermented from plant sources) and lauric acid (typically from coconut or palm oil), 95% sodium lauroyl glutamate powder is biodegradable, skin-friendly, and aligned with Clean beauty standards. Unlike conventional sulfate-based surfactants, it preserves the skin’s natural lipid barrier while effectively removing impurities, making it a staple in mild, hypoallergenic cosmetic formulas.

Scientific Research & Safety Validation

The safety and mildness of sodium lauroyl glutamate 95% powder are backed by rigorous in vitro and human clinical studies, ensuring its reliability for cosmetic use. A 2025 technical toxicology report published by BenchChem confirmed that SLG shows extremely low cytotoxicity against human keratinocytes (HaCaT cells), with an IC50 value exceeding 320 µg/mL, meaning it does not damage skin cells at standard cosmetic usage concentrations.

The Cosmetic Ingredient Review (CIR) Expert Panel has thoroughly evaluated sodium lauroyl glutamate and deemed it safe for use in rinse-off and leave-on cosmetic products, with usage concentrations ranging from 0.003% up to 40%. Human patch tests verified that SLG causes no skin irritation at concentrations up to 10%, and in vitro eye irritation assays (OECD 492) revealed a far lower irritation potential than sodium lauryl sulfate (SLS), with an IC50 of 0.448% compared to SLS’s 0.002%.

Additional studies have proven that 95% purity SLG maintains stable foaming performance across a pH range of 5.0-9.0, with optimal lather and skin compatibility at pH 6.0-6.5, matching the skin’s natural acidic protective layer. This pH adaptability makes it suitable for Sensitive Skin, dry skin, and scalp care formulations without causing tightness or dryness.

Frequently Asked Questions About 95% SLG Powder

1. Is sodium lauroyl glutamate 95% powder suitable for sensitive skin?

Yes. As a mild amino acid surfactant, 95% SLG powder is specially formulated for sensitive and allergy-prone skin.
