Dermal absorption depends a lot on the formulation. An emulsifiable concentrate is a liquid that includes solvents and surfactants designed to dissolve and spread the pesticide on skin. Those solvents help break down the skin’s outer lipid barrier and carry the active ingredient into the skin, so it enters the body more quickly than other forms. In contrast, granular forms and dry powders stay on the surface or must first dissolve, and dust or dry formulations don’t penetrate as readily. That’s why emulsifiable concentrates are absorbed most quickly.
