Liquid suspension formulation description?

Liquid suspension formulation description?

• A. Equivalent to a concentrated suspension of a wettable powder; fine particles suspended in a liquid concentrate that disperses in the spray tank; needs constant agitation
• B. A true solution in water; requires little agitation
• C. A purely oil-based product with no water compatibility
• D. A dry granule that dissolves in water

Answer: (A)

Liquid suspension formulations keep the active ingredient as finely divided solid particles dispersed in a liquid carrier. This works like a concentrated suspension of a wettable powder: the tiny solids stay suspended in a liquid concentrate and then disperse when added to water in the spray tank. Because those particles can settle out over time, constant agitation is needed to keep the mixture uniform and to re-suspend any material that has settled. This differs from a true solution, where the active would be dissolved and require little agitation; or an oil-based product that wouldn’t mix with water; or a dry granule that simply dissolves in water. So the description fits a concentrated suspension of a wettable powder that disperses in the spray tank and requires agitation to stay uniform.
