Overview
Calcium dodecylbenzenesulfonate is an anionic surfactant with strong lipophilic properties, widely used as a key emulsifier component in agricultural chemical formulations. It is typically combined with nonionic surfactants to create stable emulsifiable concentrates (EC) and other pesticide delivery systems.
Applications
Pesticides: Used in the preparation of emulsifiable concentrates for insecticides, acaricides, and nematicides.
Fungicides: Provides effective emulsification for systemic and contact fungicides.
Herbicides: Essential for formulating selective and non-selective herbicide concentrates.
Other agrochemicals: Also applicable in plant growth regulators and adjuvants.
Performance Features
Excellent emulsifying and dispersing properties when paired with appropriate nonionic surfactants.
Provides good stability in concentrated formulations and after dilution with water.
Compatible with a wide range of organic solvents and active ingredients.
Offers low skin irritation and good environmental compatibility when used as directed.
Recommended Usage
Typically used at 5 to 20 percent of the total formulation, depending on the active ingredient and desired emulsion stability. Optimize through compatibility testing with specific nonionic co-emulsifiers.
Handling and Storage
Store in a cool, dry place away from direct sunlight and heat sources.
Keep containers tightly closed to prevent moisture ingress.
Handle with standard chemical protective equipment (gloves, goggles, protective clothing).
In case of skin contact, wash with soap and water; if swallowed, seek medical attention.
Packaging
Available in 25 L, 200 L drums, and IBC containers. Custom packaging upon request.
Shelf Life
24 months when stored under recommended conditions.
Quality Assurance
Each batch is tested for active content, pH, water content, and emulsification performance to ensure consistent quality.
