Description

Stearoyl Sarcosine is a high-purity, long-chain fatty acid derivative of the amino acid sarcosine. This versatile compound is valued for its excellent surfactant properties, acting as a powerful anionic emulsifier, foaming agent, and corrosion inhibitor in demanding formulations. It is essential for manufacturers in the personal care, industrial cleaning, and metalworking industries seeking to enhance product performance and stability.

Application

• Personal Care & Cosmetics: Primary surfactant and foaming agent in shampoos, facial cleansers, and bath products due to its mildness and excellent lather.
• Industrial Cleaners & Detergents: Key ingredient in heavy-duty liquid soaps, floor cleaners, and institutional detergents for its superior emulsifying and degreasing power.
• Metalworking Fluids: Effective corrosion inhibitor and emulsifier in synthetic and semi-synthetic cutting fluids and coolants.
• Textile & Leather Processing: Used as a wetting agent, emulsifier, and softener in various finishing and treatment baths.
• Agricultural Formulations: Employed as an adjuvant and emulsifier in pesticide and herbicide concentrates to improve spray coverage and efficacy.
• Polymer & Rubber Industry: Functions as an internal and external lubricant and mold release agent during processing.
