What is one of the advantages of emulsifiable concentrates (EC)?

1. Easy to transport, handle, and store

2. Low concentration of active ingredient

3. Inhibits skin absorption

4. Leaves a visible residue

The correct answer is: Easy to transport, handle, and store

Emulsifiable concentrates (EC) are favored for several reasons, one of which is their ease of transport, handling, and storage. These formulations have a low viscosity, which allows them to be packaged in relatively lightweight containers, making them convenient to carry. Additionally, they mix well with water, presenting an advantage in application as they can easily be diluted to the appropriate concentration before use. Their concentrated nature means that smaller volumes are required for application compared to some other formulations, further enhancing their portability. While low concentration of active ingredient, inhibiting skin absorption, and leaving a visible residue might provide certain benefits in specific contexts, they do not capture the main advantages of EC formulations. Low concentration can lead to more product needing to be used for effective results, potentially increasing overall costs. Inhibiting skin absorption is a characteristic that varies based on the formulation and the specific chemical nature of the active ingredient, and leaving a visible residue is generally seen as a drawback rather than an advantage.
