Highly effective emulsifier for oil-in-water systems with excellent stability across broad pH and electrolyte ranges.
Superior wetting and dispersing performance on hydrophobic substrates, including pigments and fillers.
Low foaming characteristic suitable for high-shear industrial cleaning and metalworking fluid formulations.
Good biodegradability profile compared to traditional alkylphenol ethoxylates (APEOs), supporting sustainable formulation goals.
Thermally stable up to 80 °C, enabling compatibility with hot-process applications such as textile scouring and industrial degreasing.
Metalworking fluids – used as emulsifier and stabilizer in soluble oils and semi-synthetic coolants.
Industrial cleaning formulations – key component in heavy-duty alkaline cleaners for automotive and aerospace parts.
Pigment dispersion systems – enhances stabilization in solvent-based coatings and inks.
Textile auxiliaries – employed in scouring and desizing baths for polyester/cotton blends.
Agrochemical adjuvants – improves solubilization and foliar spread of active ingredients in EC and SC formulations.
