Which nail product is known to cause allergic reactions in some individuals?

Toluene is a solvent commonly found in various nail products, such as nail polish and nail polish removers. It is known to be a potential allergen, meaning that it can trigger allergic reactions in some individuals. These reactions can manifest in different ways, including skin irritation, dermatitis, or respiratory problems, particularly in individuals who are sensitive to the chemical.

In contrast, water and vegetable oil are generally considered safe and do not typically cause allergies, while petroleum jelly is also unlikely to provoke an allergic response, as it’s often used to soothe and protect the skin. Thus, toluene stands out among the choices as the product that is most commonly associated with allergic reactions.
