Final answer:
Buffing nail polish is used with a buffer to add shine to the nails. Some nail products contain toxic chemicals, but buffing polishes typically do not. Consumers often look for alternatives without harmful substances like DBP, toluene, and formaldehyde.
Step-by-step explanation:
A nail cosmetic used with a buffer to add shine to the nail is a buffing nail polish. Buffing polishes or creams are generally free from harmful chemicals and work by smoothing out the surface of the nails to give them a glossy finish without the use of color. However, it is important to note that some nail products can contain toxic chemicals such as dibutyl phthalate (DBP), toluene, and formaldehyde. These substances have been linked to various health concerns, and consumers are increasingly seeking alternatives that are free from these potentially hazardous ingredients.
