Sodium Lauryl Amphoteric Ethacetic Acid (commonly classified under IUPAC structures and known commercially as Sodium Lauroamphoacetate, CAS No. 68608-66-2 or 156028-14-7) is a zwitterionic amphoteric surfactant. Its unique molecular architecture combines a lipophilic hydrophobic lauryl chain with a hydrophilic imidazoline-derived headgroup containing both acidic carboxylate groups and basic nitrogen atoms.
This dual-charge structure provides an extremely low Critical Micelle Concentration (CMC) compared to traditional anionic surfactants. It adapts its ionization state to the system's pH: displaying cationic behavior in acidic environments and anionic behavior in alkaline media. When formulated alongside alkyl sulfates like SLS Needle K12, it forms mixed micellar aggregates. This decreases the overall monomer concentration of harsher surfactants, reducing skin penetration and irritation potential.
By preventing the denaturation of stratum corneum proteins (as verified by the Zein test and Red Blood Cell lysis assays), this surfactant acts as a mild cleanser that preserves the epidermal lipid barrier. It ensures high foam density and stability without stripping natural moisture.
Why modern personal care chemists and global procurement teams select Sodium Lauryl Amphoteric Ethacetic Acid for high-tier formulations.
Significantly dampens the irritation index of primary anionic surfactants. Indispensable for "tear-free" baby shampoos, intimate washes, and formulations targeting hyper-sensitive skin.
Collaborates with nonionic surfactants like APG0810 Caprylyl Glucoside to generate a stable, cream-like lather, improving sensory performance even in hard water.
Exhibits exceptional chemical stability across pH 3.0 to 11.0, rendering it highly effective in both acidic facial exfoliants and alkaline sanitizers.

How we ensure global compliance, supply security, and batch uniformity for major personal care brands.
Exporting chemical raw materials globally requires adherence to international regulatory frameworks. Our factory-produced Sodium Lauryl Amphoteric Ethacetic Acid complies with key standards:
Every single batch of surfactant leaving our Suzhou production site undergoes rigorous batch-testing protocols. We maintain archived control samples for up to 3 years. Utilizing advanced analytical gear (HPLC, GC, FTIR, and ICP-MS), we verify active concentration, trace metal profiles, and free amine remnants. This provides a transparent supply chain for our global partners.
Sustainable green chemistry is transforming the personal care industry. Here is how amphoteric surfactants support this transition.
Consumers increasingly seek sulfate-free, silicone-free, and paraben-free products. This drives demand away from traditional ethoxylated alkyl sulfates like SLES toward mild amphoteric mixtures.
Modern raw materials must break down safely in wastewater systems. Our amphoteric ethacetic acid demonstrates rapid biodegradability with minimal aquatic toxicity.
Energy costs and carbon emission regulations urge brands to adopt cold-mix formulas. Being highly water-soluble at room temperature, this liquid surfactant saves heating energy during industrial formulation.
