How does the formulation of a pesticide affect skin absorption?

The formulation of a pesticide plays a significant role in how substances are absorbed through the skin, and oil-based products generally have a higher absorption rate compared to other types. This is largely due to the properties of the skin's outer barrier, which consists of lipids (fats) that easily interact with and allow penetration by oil-based formulations. These products can better dissolve in the natural oils present on the skin, enhancing their ability to penetrate the skin barrier.

In contrast, water-based products may not be absorbed as effectively because they do not match the lipid environment of the skin as well as oil-based products do. The skin's protective barrier is designed to resist the passage of water-soluble substances, making it less permeable to these formulations. Therefore, understanding the differences in formulations can help applicators choose the appropriate pesticide while also considering the potential for dermal absorption.
