Which option identifies a disadvantage of Flowable (F) that relates to mixing with water?

• A. Easy to mix with water
• B. Spray mix needs constant agitation
• C. Good for porous surfaces
• D. Fast drying

Answer: (B)

Flowable formulations are suspensions of fine active ingredient particles in water. Because those solids tend to settle out, the spray mix must be kept in motion during application to maintain a uniform distribution of the product. This constant agitation is a disadvantage tied to mixing with water, since stopping agitation leads to separation, uneven coverage, and potential nozzle clogging or inconsistent effectiveness. The other statements describe aspects that aren’t about the mixing requirement: easy to mix with water is actually a plus, not a drawback; being good for porous surfaces and fast drying relate to where or how the product works, not the need to keep the suspension evenly mixed.
