Description

Stearoyl Ethanolamide CAS NO 111-57-9 is a high-purity fatty acid ethanolamide derived from stearic acid. This versatile compound serves as a critical intermediate and functional additive, valued for its surfactant and viscosity-modifying properties. It is essential for manufacturers in the personal care, cosmetics, and industrial lubricant sectors seeking reliable performance and formulation stability.

Application

• Primary surfactant and foam booster in shampoos, body washes, and liquid soaps.
• Key viscosity modifier and opacifying agent in cream and lotion formulations for personal care.
• Emulsifier and stabilizer in cosmetic creams, makeup, and sun care products.
• Intermediate in the synthesis of more complex amidoamine surfactants and conditioning agents.
• Additive in industrial lubricants and metalworking fluids for corrosion inhibition and stability.
• Component in textile auxiliaries and fabric softeners.
• Used in agricultural adjuvant formulations to enhance pesticide and herbicide efficacy.
