Which dry/solid formulation is mixed in water and reduces the risk of inhalation exposure during mixing and loading?

• A. Water-dispersible granules (WDG)
• B. Dry flowables (DF)
• C. Wettable powder (WP)
• D. Emulsifiable concentrate (EC)

Answer: (A)

Dust exposure during mixing and loading depends on how the product is formulated. Dry formulations that are designed to be mixed in water and stay as a suspension generate far less airborne dust than powders. Water-dispersible granules are dry granules that rapidly disperse in water to form a suspension, so they don’t create a dusty cloud when you add them to water. This makes inhalation exposure much lower during the mixing and loading process. In contrast, wettable powders are actual powders that can become airborne easily; dry flowables, while also solid, can still produce some dust, and emulsifiable concentrates are liquids with exposure concerns more related to splashes than inhalation of powder dust. So, water-dispersible granules best reduce inhalation risk during mixing and loading.
