Explore our high-performance surfactant range, specifically engineered to provide mildness, rich foaming, and superior formulation compatibility.
Sodium Lauroyl Sarcosinate (CAS No. 137-16-6), an anionic surfactant derived from sarcosine (an amino acid naturally occurring in the body) and lauric acid (a fatty acid obtained from coconut oil or palm kernel oil), represents a foundational component in the transition toward clean, sustainable, and highly effective personal care formulations. Unlike traditional alkyl sulfates like Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES), Sodium Lauroyl Sarcosinate offers exceptional skin mildness, outstanding foaming characteristics in both hard and soft water, and compatibility across a broad pH spectrum.
Globally, consumer demands have shifted decisively away from harsh chemical foaming agents towards gentle, biodegradable alternatives. This paradigm shift has created a significant manufacturing and sourcing opportunity for formulation chemists and global supply chain directors. Finding a direct, reliable wholesale manufacturing partner is critical to securing stable supply chains, achieving cost efficiencies, and maintaining batch-to-batch quality control.
INCI Name: Sodium Lauroyl Sarcosinate | CAS Number: 137-16-6 | Active Matter Formats: 30% Liquid and 95% Powder. The molecular structure combines a hydrophobic hydrocarbon chain derived from natural fats with a hydrophilic amino acid residue, generating rich, stable, creamy lather while safeguarding the natural skin barrier.
From a formulation perspective, Sodium Lauroyl Sarcosinate is not merely an alternative surfactant; it is a performance enhancer. In hair care, it adsorbs gently onto the keratin protein fibers without stripping the lipid barrier, reducing static and improving manageability. In oral care, it is widely utilized for its enzymatic inhibition properties, contributing to plaque reduction while maintaining a clean, chemical-free flavor profile. Furthermore, when combined with amphoteric surfactants such as Cocamidopropyl Betaine (CAB-35) or non-ionic options like Lauryl Glucoside (APG1214), it exhibits a highly synergistic thickening response, reducing the amount of synthetic rheology modifiers required in clean formulations.
How Suzhou Yuantairun Chemical Co., Ltd. blends cutting-edge technology, process safety, and efficiency to power global brands.
Our state-of-the-art facilities feature fully enclosed, automated condensation reaction loops. This eliminates batch fluctuation, optimizes chemical conversion, and guarantees low levels of free fatty acids and inorganic salts in the finished surfactant.
Each batch undergoes online HPLC and GC verification processes. We monitor critical parameters, including active content, pH stability, heavy metals, and chloride residues, to satisfy pharmacopoeia-level purity requirements.
Located in the Suzhou industrial hub with direct transit lanes to major ports like Shanghai, we offer robust warehousing and tailored packaging solutions (IBC totes, steel drums, fiber drums) that ensure safe, timely international shipments.
The manufacturing process of Sodium Lauroyl Sarcosinate has entered a new phase centered on decarbonization and biological synthesis. Historically, the synthesis relied on the Schotten-Baumann reaction mechanism, condensing lauroyl chloride with sodium sarcosinate under alkaline conditions. While highly efficient, this pathway yields sodium chloride as a byproduct, requiring intensive purification processes to minimize salt content, which is essential for stable formulation viscosity.
Our R&D division at Suzhou Yuantairun Chemical Co., Ltd. is actively exploring catalytic synthesis options. By utilizing green, non-toxic catalysts, we aim to decrease energy input during synthesis and reduce chloride content to less than 0.2% in liquid products. This enables formulators to achieve consistent thickening using standard sodium chloride addition, without the threat of formula instability or cloudiness at low temperatures.
For anhydrous formulations—such as powder cleansers, syndet shampoo bars, and waterless cosmetics—the demand for high-active powder forms has surged. Our proprietary spray-drying and micro-crystallization technologies enable us to manufacture Sodium Lauroyl Sarcosinate 95% Powder with excellent flowability, zero dusting hazards, and rapid dissolution speeds in cold water. This technological step forward empowers global beauty brands to transition to plastic-free, waterless product concepts without sacrificing foaming speed or volume.
Transitioning to 100% bio-based raw materials. By partnering with certified sustainable palm and coconut oil suppliers (RSPO IP & SG models), we are moving closer to a completely circular carbon footprint, satisfying consumer groups that demand clean chemical declarations.
