An authoritative exploration of CAS 30364-51-3, explaining its molecular advantages, surfactant chemistry, and why the 30% preservative-free liquid is the benchmark for clean-beauty formulations.
Sodium Myristoyl Sarcosinate is an anionic amino acid surfactant derived from the natural condensation of myristic acid (a saturated 14-carbon fatty acid) with sarcosine (N-methylglycine). Structurally, it falls within the acyl sarcosinate class. Because of its specific carbon-chain distribution ($C_{14}$), it offers an exceptional balance between the rich foaming performance typical of lauryl derivatives ($C_{12}$) and the intensive mildness characterized by stearoyl/palmitoyl equivalents ($C_{16}$ and $C_{18}$).
Unlike traditional sulfates, such as Sodium Lauryl Sulfate (SLS) or Sodium Laureth Sulfate (SLES), Sodium Myristoyl Sarcosinate possesses a bulky hydrophilic head group coupled with a methyl amide linkage. This molecular architecture prevents deep penetration into the stratum corneum, substantially reducing the risk of protein denaturation and subsequent skin irritation. Its CAS Registry Number is 30364-51-3, and it is widely designated under the INCI nomenclature for high-tier cosmetic applications.
“The thermodynamic characteristics of acyl sarcosinates exhibit a higher critical micelle concentration (CMC) than sulfates, translating directly to reduced cell membrane disruption and an ultra-mild dermatological profile.”
In modern personal care development, formulation flexibility is paramount.苏州源泰润 Chemical supplies Sodium Myristoyl Sarcosinate as a 30% active aqueous solution, completely free from added chemical preservatives. This configuration provides distinct advantages for formulators:

Understanding why multinational cosmetic brands are transitioning from traditional ethoxylated surfactants to premium amino acid alternatives.
Global regulatory bodies, particularly in the European Union (under ECHA Regulations) and North America, are continuously tightening restriction limits on 1,4-Dioxane—a byproduct of ethoxylation found in SLES. Amino acid surfactants like Sodium Myristoyl Sarcosinate are intrinsically 1,4-dioxane free, presenting the most reliable, compliant alternative for clean-beauty formulas.
Modern consumers demand sustainable sourcing and packaging. Our Sodium Myristoyl Sarcosinate 30% Liquid is synthesized via principles of green chemistry. It boasts a biodegradation rate of over 90% within 28 days, minimizing aquatic toxicity and fitting seamlessly into eco-certified cosmetic ranges.
With clinical studies noting an increase in self-reported sensitive skin globally, there is rising demand for products that protect the epidermal barrier. Sarcosinates provide excellent degreasing without stripping natural intercellular lipids, making them a preferred choice for clinical skincare brands.

Aligning green synthesis, decarbonization, and performance chemistry to meet 2030 sustainability mandates.
Traditional chemical synthesis of acyl sarcosinates relies on the Schotten-Baumann reaction, involving fatty acid chlorides and sarcosinate salts in alkaline aqueous media. While highly efficient, this route generates sodium chloride as a byproduct. Yuantairun's tech roadmap focuses on transitioning toward enzymatic condensation pathways using modified lipases. This green synthesis approach lowers process energy requirements, limits inorganic salt generation, and yields an ultra-pure product with an even lower carbon footprint.
In addition, by prioritizing RSPO-certified palm kernel oil and sustainable coconut oil as feedstock, we help global cosmetic manufacturers reduce their Scope 3 upstream emissions. This supports efforts to align formulation chemistry with corporate net-zero carbon goals.
Answers to essential technical and commercial questions regarding Sodium Myristoyl Sarcosinate 30% Liquid.
Sodium Myristoyl Sarcosinate features a 14-carbon chain ($C_{14}$), while Sodium Lauroyl Sarcosinate uses a 12-carbon chain ($C_{12}$). The slightly longer hydrophobic carbon chain of the Myristoyl derivative makes it milder, offering a creamier skin feel and better conditioning properties. In contrast, the Lauroyl version provides slightly faster flash foam. The Myristoyl variant is ideal for sensitive skin and premium facial cleansers.
Many multi-functional preservatives present in surfactants can trigger contact dermatitis in consumers or conflict with other ingredients in a formula. Providing a preservative-free raw material allows brands to implement their own customized preservation systems. It also simplifies regulatory compliance for clean-beauty labeling.
Under recommended storage conditions—sealed in original packaging at temperatures between 5°C and 35°C—the product remains stable for 12 months. Since it is preservative-free, it is vital to avoid microbiological contamination after opening, using appropriate sanitary handling practices.
Unlike harsh anionic surfactants that strip both skin lipids and natural moisture, Sodium Myristoyl Sarcosinate cleanses selectively. It solubilizes surface sebum without penetrating or disrupting the lipid bilayers of the stratum corneum, helping skin maintain hydration after wash.
We provide full documentation, including REACH registration, RSPO supply chain certification for palm-derived fatty acids, HALAL compliance certificates, and comprehensive MSDS sheets detailing safe transport and handling protocols.
