Oil-based pesticides do what to the skin?

• A. Absorb slowly
• B. Remain on surface
• C. Absorb quickly into skin
• D. Evaporate instantly

Answer: (C)

Oil-based pesticide formulations can be absorbed quickly into the skin because the skin’s outer barrier is lipid-rich. Oils mix with those skin lipids and carry the active ingredient through the stratum corneum, so dermal absorption tends to be faster than with many other types of formulations. This means they’re not simply left on the surface or evaporated away; they can penetrate the skin relatively rapidly. Of course, factors like contact time, concentration, and skin condition influence the rate, but the general idea is that oil-based products enhance skin absorption. That’s why using proper protection and washing exposed skin promptly are important.
