Which statement correctly describes emulsifiable concentrates?

• A. They form milky suspensions and require minimal agitation.
• B. They form milky suspensions and require some agitation.
• C. They are dry granules.
• D. They are always true solutions in water.

Answer: (B)

Emulsifiable concentrates are liquid formulations that are designed to disperse in water to form an emulsion. When you mix an EC with water and agitate, you see a milky appearance because tiny droplets of the concentrate are dispersed throughout the water. This emulsion needs some agitation to form and stay uniform; without sufficient mixing, droplets can coalesce and separate. They are not dry granules, and they are not true solutions in water, since the active ingredient is not dissolved but dispersed as droplets. So the best description is that they form a milky emulsion in water and require some agitation.
