Which of the following characteristics is NOT true for emulsifiable concentrates?

Emulsifiable concentrates are designed to effectively disperse active ingredients in a liquid form, making them a common choice in pesticide applications. One notable characteristic of these formulations is that they generally do not penetrate the skin very deeply, which supports the assertion that they do not absorb into the skin. This trait can be advantageous in terms of safety, as it reduces the risk of systemic exposure to pesticides through dermal absorption.

However, the other characteristics listed reflect typical qualities of emulsifiable concentrates. They require frequent agitation to maintain the uniformity of the mixture, as the emulsifying agent can separate if left undisturbed. While they are often regarded as easy to handle due to their liquid formulation, some users may find the strong odor of certain emulsifiable concentrates off-putting. Therefore, the assertion that they do not absorb into the skin stands out as a correct reflection of their properties, supporting the identification of it as the characteristic that is not true for emulsifiable concentrates in this context.
