Which formulation dissolves in water?

Which formulation dissolves in water?

• A. Emulsifiable concentrates
• B. Soluble powders
• C. Water-dispersible granules
• D. Wettable powders

Answer: (B)

When a formulation dissolves in water, it forms a true solution where the active ingredient is distributed at the molecular level with no solid residues. Soluble powders are designed to do this—they break apart and dissolve quickly in water, giving a uniform, clear solution that sprays evenly and leaves little to no particulate material. Other formulations behave differently in water. Emulsifiable concentrates create an oil-in-water emulsion, so they mix as droplets in water rather than fully dissolving. Wettable powders and water-dispersible granules are meant to wet and disperse or suspend in water rather than dissolve completely, often requiring agitation to keep them uniformly distributed.
