Sodium Methyl Cocoyl Taurate (CAS No. 12765-39-8 / 61791-42-2) represents a pinnacle class of high-performance amino acid-based anionic surfactants. Derived from the condensation of natural coconut oil fatty acids with methyl taurine (an organic amino acid derivative found natively in animal tissues), SMCT functions as a mild, dense-foaming primary or secondary surfactant.
Unlike traditional alkyl sulfates (such as SLS and SLES), which are notorious for disrupting skin lipid bilayers and inducing protein denaturation, Sodium Methyl Cocoyl Taurate possesses a unique structure containing a highly hydrophilic sulfonic acid head-group and an amide linkage. This molecular arrangement ensures deep compatibility with keratinous substrates, resulting in a low irritation index, superior dermatological tolerance, and outstanding flash-foaming capabilities even in the presence of hard water and sebum.
Extensive Zein tests and patch tests indicate that SMCT causes negligible protein denaturation compared to ether sulfates. Its critical micelle concentration (CMC) is optimized to minimize trans-epidermal water loss (TEWL).
Unlike soap bases, SMCT maintains its structural integrity and foaming profile under high mineral concentrations (calcium/magnesium ions), ensuring stable rheology and tactile quality globally.
As multinational personal care giants pivot away from sulfate-based cleansers, the market for taurate-based surfactants is experiencing exponential compound annual growth (CAGR).
B2B procurement professionals seek raw material security, batch-to-batch consistency, and stable pricing matrixes. We offer standardized logistics pathways, ensuring stable supply chains in APAC, North America, and the EU.
With stricter global standards (EU REACH compliance, US MoCRA, China NMPA registrations), we ensure our products undergo rigorous purity screenings, providing clean documentation sheets for quick compliance validation.
Our factories support multiple physical forms: 30% liquid active matter (optimal for cold process manufacturing systems) and 90%+ high-purity powder and granular states (perfect for solid shampoo bars and powdered cleansers).
Our synthesis route utilizes advanced green chemistry engineering to significantly limit the presence of undesirable sub-components (such as free amines and sodium chloride). Sodium Methyl Cocoyl Taurate is processed via the direct reaction of high-purity cocoyl chloride with sodium methyl taurate in a aqueous medium under controlled alkaline pH (Schotten-Baumann condensation).
We employ modern crystallization and purification protocols, optimizing thermal efficiency and lowering volatile organic compounds (VOCs). Through this process, we reduce carbon footprint benchmarks, aligning with zero-waste targets established by global sustainability committees.

Our chemical solutions are optimized to build outstanding foaming and viscosity profiles in diverse daily chemical categories.
When coupled with Sodium Cocoyl Glutamate (YG02-95) and Sodium Lauroyl Sarcosinate (LS-100N), SMCT forms a luxurious, dense foam system that cleanses without striping natural skin moisture. Excellent compatibility with sensitive skin formulas.
In premium hair care, SMCT synergizes with Lauryl Glucoside (APG1214) and Cocamidopropyl Betaine (CAB-35). It provides exceptional color protection, increases viscosity response, and reduces the irritation associated with standard anionic thickeners.
Due to its low eye irritation potential (ophthalmologist-tested safe) and rapid biodegradation index, SMCT serves as a major primary surfactant for high-end tear-free baby soaps and moisturizing bubble baths.
At Suzhou Yuantairun Chemical Co., Ltd., we assure you that our products originate from well-managed, sustainable resources. We guarantee complete traceability and validation documentation to support our partners' compliance framework.
We provide customized solutions across international ports, utilizing protective container lines to avoid separation or freezing during transits. Just-in-time delivery guarantees that materials are delivered exactly when needed in the production process, reducing storage overhead costs.
Direct answers from our senior R&D engineers on formulating, storage, and procurement parameters for Sodium Methyl Cocoyl Taurate.
A1: While both are outstanding mild anionic surfactants, SCI has limited solubility in cold water and tends to crystallize out of liquid systems, making it primary for solid shampoo bars. SMCT has a highly stable solubility index in cold water and liquid systems, rendering it much easier to formulate into clear facial washes and shampoos without high heat processing.
A2: Sodium Methyl Cocoyl Taurate is stable within a broad pH range of 5.5 to 8.5. It exhibits exceptional thermal stability and hydrolysis resistance. In slightly acidic environments (pH 5.5 - 6.5), which mimic natural skin pH, it provides excellent flash foam and stable viscosity in combination with amphoteric co-surfactants.
A3: Since SMCT contains a sulfonic acid structure, it does not respond to salt thickening (sodium chloride) as readily as SLES does. To build viscosity, we recommend using non-ionic surfactants like Cocamide MIPA or APG1214, or incorporating natural hydrophilic polymers such as Xanthan Gum, Guar Gum, or synthetic acrylic polymers (PAAS).
A4: Yes, we prioritize environmental sustainability. Our raw coconut fatty acids can be sourced through Mass Balance (MB) RSPO-certified logistics chains upon request, supporting sustainable oil production and protecting natural forest systems.
A5: For our 30% liquid form, we ship in 200kg plastic drums or 1000kg IBC tanks. For our high-concentration powder products (90%+), we provide 25kg multi-layer kraft paper bags with moisture-proof PE liners to protect against caking during ocean transport.
