What are some common allergens found in nail products?

Formaldehyde, toluene, and dibutyl phthalate are well-documented allergens and irritants commonly found in various nail products. Formaldehyde is often used as a preservative and hardener in nail polishes and nail treatments, but it can cause allergic reactions in susceptible individuals. Toluene, a solvent used in nail polish, can also lead to skin sensitivity and respiratory issues. Dibutyl phthalate (DBP) is used to enhance the flexibility of nail products, yet it has been associated with skin allergies and other health concerns.

While some ingredients found in the other choices, like lavender and eucalyptus oil, can trigger reactions in users with specific sensitivities, they are not as commonly recognized as allergens in the nail industry as the chemicals listed in this correct answer. Vitamin E and aloe vera are generally considered safe and are often incorporated into products for their beneficial properties rather than as allergens. Similarly, coconut oil and beeswax are typically used for their moisturizing benefits and are not commonly associated with allergic reactions in the context of nail technology. Therefore, the identified chemicals in the correct answer are particularly relevant due to their frequency and potential to cause allergic reactions within the nail care context.
