Description

Stearyldiethanolamine is a high-purity tertiary amine surfactant derived from stearic acid and diethanolamine. This versatile compound is valued for its excellent emulsifying, softening, and antistatic properties, making it a key intermediate in the formulation of high-performance specialty chemicals. It is primarily utilized by manufacturers in the personal care, textile, and industrial surfactant sectors seeking reliable raw materials for stable and effective end-products.

Application

• Primary emulsifier and opacifying agent in cosmetic and personal care formulations, such as creams, lotions, and hair conditioners.
• Fabric softener and antistatic agent in textile processing and finishing applications.
• Key intermediate for the synthesis of quaternary ammonium compounds (quats) used as biocides and conditioning agents.
• Emulsifier and corrosion inhibitor in industrial lubricants and metalworking fluids.
• Raw material for producing amphoteric and cationic surfactants with enhanced mildness and compatibility.
• Additive in agricultural adjuvants to improve the spreading and adherence of pesticides.
• Conditioning and viscosity-modifying agent in household and institutional cleaning products.
