Question: what are the toxic ingredients in nail polish?
Answer: There are three main culprits found in many nail polishes: formaldehyde, toluene, and dibutyl phthalate (DBP). These chemicals are known as the "Toxic Trio" or "Big 3". Formaldehyde is a chemical that is a component in plywood and particleboard, and is often used as a preservative, sterilizer and embalmer.
