Soluble powders (SP) are formulated to contain active ingredient above 50 percent.

• A. True
• B. False
• C. Cannot be determined
• D. Not applicable

Answer: (A)

Soluble powders are dry formulations that dissolve readily in water to create a spray. They are designed to carry a relatively high amount of active ingredient so that the resulting solution has the desired potency without needing excessive material. In practice, soluble powders typically contain 50% or more active ingredient, sometimes much higher, which makes them efficient and cost-effective to apply. That’s why the statement is correct. The other choices don’t fit because SPs are defined by their high active ingredient content, not by low content, and the information is not indeterminable or inapplicable.
