In which industries and processes are emulsifiers OS and MS-1 mainly used?

Emulsifiers OS and MS-1 are mainly used in two major industries: pesticide formulation processing and textile printing and dyeing. The core processes involve the construction of emulsification and dispersion systems for emulsifiable concentrates (EC), emulsions in water (EW), suspension concentrates (SC), and microemulsions (ME).

Main Application Industries

Core Process Applications

Emulsifiable Concentrate (EC) Processing: Both are used as high-efficiency emulsifiers to rapidly dissolve and emulsify pesticide technical materials, improving the stability and dispersibility of EC, ensuring uniform adhesion of the spray liquid to the target.

Emulsion in Water (EW) Preparation: Provide excellent emulsification and stabilization, allowing the oil phase to be uniformly dispersed in the water phase as fine droplets, avoiding phase separation and demulsification, extending the shelf life of the formulation, and reducing the amount of organic solvent used. (Data source: Guoli Chemical Product Database)

Suspension Concentrate (SC) System (mainly OS): Improve the wetting and dispersion of solid technical material particles in water, prevent sedimentation and caking, optimize fluidity, and are suitable for various compounded pesticide suspension systems. (Data source: Guoli Chemical Product Database)

Microemulsion (ME) Construction: Form thermodynamically stable transparent or translucent microemulsions under low-energy emulsification conditions, enhancing transdermal penetration of the formulation, improving systemic translocation effects, and reducing application dosage.

Pesticide Compounding and Tank-Mix Adjuvants: Good compatibility when compounding multiple active ingredients, reducing physicochemical antagonism between technical materials; as tank-mix synergists, they improve the spreading and adhesion of spray liquid on leaf surfaces.

Differentiation Supplement

• Emulsifier OS (Sodium sec-alkyl sulfonate, CAS 68439-50-9): Anionic type, more prominent resistance to hard water and electrolyte stability, also used in industrial cleaning applications.
• Emulsifier MS-1 (Octylphenol polyoxyethylene ether maleate): Nonionic/anionic mixed characteristics, outstanding wetting and spreading properties, excellent compatibility with various pesticide technical materials and solvents, classified as a low-risk, harmless chemical.
