Soluble powder (SP) is a dry preparation that contains 15% to 95% active ingredient and dissolves in water to form a solution.

• A. Soluble powder (SP)
• B. Dust (D)
• C. Flowable (F)
• D. Granule (G)

Answer: (A)

Soluble powder is designed to dissolve completely in water to form a true solution. It is a dry formulation containing a substantial portion of the active ingredient (15%–95%), so when mixed with water it disappears as a single, uniform solution rather than as a suspension or as undissolved particles. This is why it fits the description provided. In contrast, a dust is simply a dry powder that doesn’t dissolve; a flowable forms a suspension in water rather than a true solution; and granules are larger particles that may dissolve more slowly or release the active ingredient gradually. So the statement aligns with the defining trait of soluble powder.
