Which chemical is commonly used in nail adhesives?

Cyanoacrylate is widely recognized as a primary ingredient in nail adhesives due to its strong bonding properties. This type of adhesive sets quickly upon contact with moisture, making it particularly effective for attaching artificial nails, nail tips, and for use in various nail art applications. In the context of nail technology, its rapid curing time and durability ensure a secure application, which is critical for both professional and at-home use.

In contrast, other chemicals listed have different uses or properties that do not align with nail adhesive functions. Formaldehyde, while used in some cosmetic formulations, is not a common adhesive component and is known for its health concerns. Cyclopentasiloxane is primarily used in hair and skincare products for its smoothing properties, rather than as an adhesive. Acetone is primarily utilized as a solvent for removing nail polish and other materials but is not an adhesive. Thus, cyanoacrylate stands out as the suitable choice for nail adhesives.
