What type of products commonly use free radical scavengers?

Free radical scavengers are substances that can neutralize free radicals, which are highly reactive molecules that can cause oxidative damage to materials and biological systems. This property is particularly valuable in a variety of products that are susceptible to degradation from these radicals.

In cosmetics, free radical scavengers help protect the skin by reducing oxidative stress that can lead to aging and other skin damage. In food products, they are incorporated to extend shelf life by preventing rancidity and spoilage caused by oxidation. Plastics benefit from these additives as they can help maintain the integrity and appearance of the material over time, preventing degradation from exposure to light and heat.

Cleaning agents, while they may contain antioxidants, primarily focus on surfactants and other agents for their cleaning capabilities. Medical supplies might use different types of preservatives and stabilizers but do not exclusively rely on free radical scavengers. Transportation fuels can also contain additives for stability and efficiency but do not typically use free radical scavengers as a primary component.

Therefore, the presence of free radical scavengers is crucial in cosmetics, food products, and plastics due to their ability to mitigate the harmful effects of oxidative stress and extend the longevity of these products.
