Explore our raw material portfolio, manufactured strictly under ISO certifications to ensure premium stability and compatibility in cosmetic applications.
In the highly competitive personal care market, formulation science is rapidly transitioning from harsh synthetic sulfates to mild, eco-responsible amino acid-based surfactant technologies. Sodium Methyl Cocoyl Taurate (SMCT) 95% Powder (CAS NO.: 61791-42-2) stands at the apex of this paradigm shift.
As a highly purified anionic surfactant derived from coconut-based fatty acids and methyl taurine, SMCT exhibits exceptional foaming dynamics, excellent stability across a broad pH spectrum, and unparalleled mildness. Unlike liquid variants that often require chemical preservatives to maintain microbiological stability, our 95% active powder form is completely preservative-free. Its low water activity inhibits microbial development natively, providing cosmetic formulators with a clean label solution for premium face washes, baby care shampoos, and solid syndet bars.
Highly concentrated solid powder reduces shipping volume, footprint, carbon impact, and formulation design constraints. It contains zero moisture carrier, bypassing the need for added biocides or preservatives.
Avoids common allergens, formaldehyde-releasers, and parabens. Ideal for hypo-allergenic, organic, clean-beauty, and clinical skin-cleansing formulas requiring minimal sensitization risk.
Leverages the structure of taurine (aminoethanesulfonic acid) to secure high foaming capacity without compromising the lipid barrier of the stratum corneum.

The structural design of Sodium Methyl Cocoyl Taurate is rooted in advanced green chemistry principles. The conventional production process, involving cocoyl chloride condensation with sodium N-methyltaurate (Schotten-Baumann reaction), has been modernized through our continuous green synthesis pathway.
By using direct condensation routes under moderate temperatures and catalytic cycles, we have significantly minimized the production of reaction byproducts and reduced the environmental load. The starting fatty acid cuts are meticulously fractionated from natural coconut oil to guarantee a stable chain length distribution (chiefly C12 lauric and C14 myristic), ensuring optimal balance between dissolution rate, cleansing power, and lather density.
Our research lab is currently testing novel bio-catalytic enzymes to replace inorganic bases in the condensation phase. This aims to lower energy consumption by 35% and narrow the molecular weight distribution of the resulting surfactant.
Looking toward 2030, our R&D roadmap integrates circular raw materials, such as bio-derived methyl taurine and fatty acids sourced from microalgae, decoupling surfactant production from agricultural arable land demands.
To assist global formulators who manufacture solid shampoo bars, dry dry-shampoos, and wash powders, we are launching an optimized micro-granulated powder with zero dusting characteristics, preventing industrial inhalation hazards during production.
Formulators face the recurring challenge of finding mild surfactants that do not compromise flash foam speed or total volume. Sodium Methyl Cocoyl Taurate solves this issue through its unique structural properties.
The hydrophilic head group of SMCT, containing an N-methylated amide coupled with a highly polar sulfonate group, creates a large hydration sphere. This configuration facilitates rapid packing at the air-water interface, resulting in a rich, dense, and creamy micro-foam that closely mimics the flash foaming of ethoxylated sulfates like SLES, yet remains exceptionally gentle on proteins and lipids in human skin.
SMCT maintains the integrity of the skin lipid barrier. It prevents dry skin tightness, making it a key active ingredient for facial cleansers, eczema-prone skin formulations, and dermatologist-recommended daily washes.
Provides deep hair-follicle cleansing without stripping natural moisture. It is safe for color-treated and chemically straightened hair, providing wet combability and minimizing frizz.
The high active powder structure is ideal for binding solid soap-free syndets, enhancing the structural integrity, cracking resistance, and wear-rate of the bars.
Boasts low ocular irritation scores (Tear-Free formulations). Delivers thick, fun bubble volumes while keeping the skin barrier hydrated and protected.
When combined with amphoteric surfactants like Cocamidopropyl Betaine (CAB-35) or non-ionics like Caprylyl/Capryl Glucoside (APG0810), SMCT shows a strong synergistic viscosity-building effect. The presence of the methyl taurate group reduces the critical micelle concentration (CMC) of the mixed system, leading to enhanced foam stability, improved tolerance to sebum, and reduced skin irritation indexes.
Suzhou Yuantairun Chemical Co., Ltd. operates at the forefront of chemical manufacturing by implementing Factory 4.0 intelligent infrastructure. Our production site is designed to ensure maximum process control, ecological sustainability, and stable product quality.
Through DCS (Distributed Control Systems) and computerized dosing loops, we monitor reaction temperatures, feed ratios, and condensation rates in real time. This micro-level process management minimizes batch-to-batch variation, ensuring that viscosity, active matter levels, and trace salt content remain within strict tolerances. Our close proximity to major shipping terminals in Shanghai and Suzhou guarantees prompt container dispatches, helping global personal care brands maintain lean, just-in-time production schedules.
By leveraging continuous spray-drying technology rather than static oven drying, we yield a fine, highly flowable powder with a uniform particle size distribution. This prevents clumping and simplifies dissolution during formulation blending.
Our facility recycles 90% of industrial process water via advanced reverse osmosis, returning high-purity water to the production cycle and minimizing discharge footprints.
