AGNIQUE CSO-35 helps agrochemical formulations maintain a stable emulsion structure when oil-based ingredients are mixed with water.

AGNIQUE CSO-35 improves formulation consistency by supporting better wetting, dispersion, and compatibility between different formulation phases.

AGNIQUE CSO-35 is useful in crop protection products that need dependable emulsification performance and uniform active ingredient delivery.

AGNIQUE CSO-35 is a nonionic castor oil ethoxylate used as an emulsifier and formulation aid in agrochemical products.

AGNIQUE CSO-35 contains approximately 35 EO units, giving it a balanced but slightly more hydrophilic character than lower-EO castor oil ethoxylates.

AGNIQUE CSO-35 helps oil-based or poorly water-soluble active ingredients disperse more evenly in water and supports stable emulsion formation in EC, EW, SE, and OD formulations.

AGNIQUE CSO-35 also provides wetting and adjuvancy properties, making it useful in crop protection systems that require good emulsification, spray performance, and uniform active ingredient distribution.

Applications of AGNIQUE CSO-35:

AGNIQUE castor oil ethoxylates are biodegradable and derived from natural sources.

Typically, they are used as non-ionic emulsifiers often matched with anionic counterparts such as CaDDBS to give optimum stability in formulations such as EC, EW, SE, and OD. In addition, AGNIQUE CSO products show wetting and adjuvancy properties. 

AGNIQUE CSO-35 is applied in agrochemical formulations where oil-based active ingredients need to be dispersed smoothly and consistently in water.

AGNIQUE CSO-35 is especially useful in emulsion-based crop protection systems because it helps maintain a uniform mixture during preparation, dilution, and spraying.

AGNIQUE CSO-35 can be used in formulations that require improved compatibility between hydrophobic components and aqueous phases, supporting better product stability and reducing the risk of separation.

AGNIQUE CSO-35 is also suitable for pesticide, herbicide, fungicide, and insecticide products where efficient emulsification, wetting, and even active ingredient distribution are important for reliable field performance.
