Which formulation type disperses in water to form a suspension?

• A. Wettable powders (WP)
• B. Water soluble concentrate
• C. Oil solubles
• D. Invert emulsions

Answer: (A)

Wettable powders are dry, finely ground solids that include a wetting agent. When you add them to water and mix, the particles break apart and stay dispersed as a suspension rather than dissolving completely. That ability to form a uniform mix with solid particles suspended in water is why they’re described this way. Water soluble concentrates, by contrast, are designed to dissolve fully in water, producing a true solution with no solid particles left. Oil-soluble formulations dissolve in the oil phase and, when mixed with water, tend to form an emulsion rather than a suspension of solids. Invert emulsions are emulsions where one liquid is dispersed in another (such as water droplets in oil or oil droplets in water) and do not create a suspension of solid particles either. So the formulation that disperses in water to form a suspension is the wettable powder.
