Description

Sorbitan, Isooctadecanoate, Poly(Oxy-1,2-Ethanediyl) Derivs. is a nonionic surfactant belonging to the sorbitan ester ethoxylate family, valued for its excellent emulsifying, dispersing, and solubilizing properties. This compound is crucial for creating stable formulations by effectively reducing surface tension between immiscible phases. It is primarily needed by manufacturers in the personal care, cosmetics, industrial lubricants, and agrochemical sectors for producing high-performance emulsions and dispersions.

Application

• Primary emulsifier and stabilizer in cosmetic creams, lotions, and sunscreens.
• Key ingredient in textile processing aids for fiber lubrication and dye leveling.
• Dispersing agent in agrochemical formulations such as pesticide and herbicide concentrates.
• Additive in industrial lubricants and metalworking fluids for emulsification and corrosion inhibition.
• Co-emulsifier in paint, coating, and ink systems to improve pigment wetting and stability.
• Surfactant component in household and institutional cleaning products.
• Processing aid in the polymer and plastics industry for internal and external lubrication.
• Excipient in pharmaceutical topical preparations as a nonionic solubilizer.
