Oil-based pesticides do what?

Explanation:
The key idea is dermal absorption and how formulation affects it. Oil-based pesticides are more lipophilic, meaning they mix with the skin’s natural oils and can partition into the lipid-rich outer layer of the skin more easily. That makes them penetrate the skin more readily, so they’re absorbed through the skin more than water-based formulations. So the statement that oil-based pesticides absorb more through skin is the best choice. They don’t completely prevent evaporation, and they don’t dry instantly—oil films can leave a greasy residue that needs washing off, not a rapid dry.
