Emulsifiable Concentrate (EC) formulations are described as:

Emulsifiable concentrates are concentrated liquid formulations in which the active ingredient is dissolved in organic solvents with emulsifiers so they form an emulsion when mixed with water. Because they come in a high concentration per container, you must measure carefully and dilute to the labeled rate before use. The solvent base means they can be flammable, and if misused or applied to sensitive plants, they can cause phytotoxic injury. They’re not abrasive and are less dusty than dry powders, and as liquids they typically require less vigorous agitation than solid formulations to maintain a stable emulsion—though you still need to keep the tank well agitated to prevent separation.
