Emulsifier EL-90 (PEG-90 Castor Oil): Basic Introduction
Emulsifier EL-90 is a non-ionic surfactant derived from castor oil ethoxylated with ~90 ethylene oxide units. It is typically a pale yellow solid or paste, soluble in water and polar solvents, with a neutral pH (5.0-7.0) and high HLB value (~16-17).
Its key role is as an efficient O/W emulsifier, stabilizing blends of oils and water. It also functions as a solubilizer, dispersant, and mild surfactant, finding use in cosmetics, agriculture (pesticide formulations), textiles (antistatic agents), and industrial cleaning due to its low irritation and strong emulsifying capacity.
Product Advantage
Outstanding Emulsifying Ability: It has a strong emulsifying capacity for mineral oils, which is crucial in industries like textile printing and dyeing. This ensures stable and uniform emulsions, enhancing the performance of related products.
Multi - functional Performance: Besides emulsifying, it also excels in wetting, dispersing, solubilizing and detergency. This multi - functionality reduces the need for multiple additives, simplifying production processes.
Wide Compatibility: Compatible with water and most organic solvents, allowing it to be used in a broad range of formulations without compatibility issues.
High Quality and Stability: Manufactured with strict quality control, ensuring consistent quality and stable performance batch after batch.
