Wettable powder (WP) is a finely divided pesticide formulation containing the original drug, carrier and filler, surfactant (wetting agent, dispersant) adjuvant. When diluted to the concentration used in the field, the preparation can form a stable suspension for spraying.

Water-dispersible granules (WDG) are also called dry suspensions or granular wettable powders. When placed in water, it can disintegrate, disperse and form a highly suspended dispersion system relatively quickly.

In liquid formulations, SC and OD are commonly used. Silica is often classified as a stabilizer in SC. In SC, manufacturers often use precipitated silica. White carbon black has the functions of thickening, anti-settling, and anti-water precipitation in SC to improve storage stability, prevent SC from "pasteing", and has high requirements for the quality of white carbon in OD formulations. Gas phase white carbon black is often used Classified as a structural stabilizer.

Plays thickening and rheological control performance in OD. White carbon black can form a three-dimensional structure in the liquid when standing still, increasing the viscosity and yield point under standing. During shearing, a shear thinning effect can be formed. Therefore, in OD, it has the functions of anti-sedimentation, anti-layering, thickening, and research assistance.
