What is Sodium Cocoyl Sarcosinate Liquid CAS 61791-59-1?

Sodium Cocoyl Sarcosinate is a mild anionic amino-acid surfactant made from coconut fatty acids and sarcosine. It is supplied as an aqueous liquid, usually with active matter around 28-32%, and is used to build dense, stable lather in cleansing and personal care formulations.

Why is Sodium Cocoyl Sarcosinate considered a mild cleansing surfactant?

Its sarcosinate structure gives good cleansing and foaming while producing a generally low-irritation profile compared with many traditional high-charge anionic surfactants. It also performs well in hard water and in the presence of sebum, so it helps maintain foam quality under realistic washing conditions.

How should Sodium Cocoyl Sarcosinate Liquid be used in a formulation?

It can be used as a primary surfactant or as a secondary/co-surfactant in shampoos, facial cleansers, body washes, foam baths, oral care, and baby products. It is typically added to the water phase, and the final pH, active concentration, and preservative system should be adjusted for the complete formulation.

Is Sodium Cocoyl Sarcosinate compatible with other surfactants and conditioning agents?

Yes, it is generally compatible with a wide range of anionic, nonionic, and amphoteric surfactants and can improve foam quality and mildness in blends. Compatibility with cationic polymers or biocides should still be checked in the specific formula because charge interaction can depend on concentration, pH, and ingredient structure.

Sodium Cocoyl Sarcosinate Liquid CAS 61791-59-1

Sodium Cocoyl Sarcosinate Liquid CAS 61791-59-1 is a highly effective anionic amino acid surfactant synthesized from coconut oil fatty acids and sarcosine, operating within the Cosmetic Raw Materials category. This Sodium N-cocoyl sarcosinate functions by significantly reducing surface tension and providing excellent foaming properties even in the presence of sebum or hard water environments. As a mild N-Cocoyl sarcosine sodium salt, it acts as a primary or secondary cleansing agent in large-scale formulation processes, exhibiting synergistic effects when combined with other ionic systems. The specific molecular structure allows this Cocoyl sarcosine sodium to form stable, dense lathers while maintaining a very low irritation profile, making it a critical Sodium cocoyl methyl glycine component for the industrial compounding of gentle cleansing matrices and oral care systems. Our facility is equipped to provide competitive factory pricing for formulation engineers requiring customized specifications regarding active matter concentration and pH levels. We ensure comprehensive regulatory compliance by supplying MSDS, TDS, COA documentation with every shipment, facilitating seamless bulk supply for global manufacturing operations.

Applications

Cosmetic Formulations: Utilized as a mild primary or secondary surfactant in the large-scale manufacturing of sulfate-free facial cleansers, body washes, and premium shampoos.
Oral Care Production: Applied as an effective foaming agent and enzyme inhibitor in toothpaste manufacturing due to its low toxicity profile and resistance to hard water.
Institutional Cleaning: Used in specialized, mild institutional cleansers and medical scrubs where high skin compatibility and rapid biodegradability are strictly required.

For surfactant systems requiring a defined lauroyl sarcosinate rather than a cocoyl chain distribution, Sodium Lauroyl Sarcosinate is a separate anionic surfactant.

Storage & Safety

Storage: Store in a tightly sealed container within a cool, dry, and well-ventilated warehouse. Keep away from strong acids and oxidizing agents. If crystallization or increased viscosity occurs at lower temperatures, warm gently to room temperature and stir until uniform before use.
Safety (PPE): Operators should wear chemical splash goggles, protective gloves, and standard factory workwear. Avoid prolonged contact with skin and eyes. In the event of exposure, flush the affected area immediately with copious amounts of clean water.

Quality Assurance

Our production center adheres to rigorous quality control standards, utilizing advanced titration methods and High-Performance Liquid Chromatography (HPLC) to accurately monitor the active matter, residual sodium chloride, and free fatty acid content. The synthesis process is conducted under strict environmental controls to minimize trace impurities, ensuring the surfactant’s stability, clarity, and foaming performance meet the exact tolerances required for high-end cosmetic and pharmaceutical applications.
