Which statement best describes monomers in nail system products?

• A. They are present in all nail system products in some form.
• B. They are never used in nail products.
• C. They exist only as solids in nail products.
• D. They are only used in color gels.

Answer: (A)

Monomers are the small molecules that link together to form the polymers that make up the cured film in nail products. In every nail system, the final layer is a polymer network created through polymerization, and that network is built from monomer units.

This is why monomers appear in all nail system products in some form: acrylics use a liquid monomer that reacts with powder to form the polymer, gels contain monomer resins that polymerize under light to create the film, and even coatings like base or top coats rely on resin systems derived from monomer units. They may show up as free monomer liquids, as monomer-based resins, or as prepolymerized oligomers that originated from monomer building blocks.

The other ideas aren’t accurate because monomer components aren’t limited to one form or one type of product. They’re not absent from nail systems, not restricted to solids, and not exclusive to color gels.
