Nail Product Chemistry
| Term | Definition |
|---|---|
| acrylates | Specialized acrylic monomers (cross-linking) that have good adhesion to the natural nail plate and polymerize in minutes. Used to make UV gels. |
| acrylics | The name for an entire family chemicals used to make all types of nail enhancements and adhesives, including wraps, glues, UV gels, and liquid/powder systems. |
| adhesion | A chemical reaction resulting in two surfaces sticking together |
| adhesive | An agent that causes two surfaces to stick together. |
| catalyst | Substances that speed up chemical reactions. |
| chemical | A substance obtained by a chemical process or producing a chemical effect. |
| coatings | Products, including nail polish, top coats, artificial nail enhancements, and adhesives, that cover the nail plate with a hard film. |
| corrosive | A substance capable of seriously damaging skin, eyes, or other soft tissues on contact Some corrosives have delayed action (minutes); others affect the skin almost instantly. |
| cross-linker | A monomer that joins together different polymer chains. |
| cyanoacrylates | A specialized acrylic monomer (non- cross- -linking) that has excellent adhesion to the natural nail plate and polymerizes in seconds; used to make wraps and nail adhesives |
| evaporate | A change from liquid to vapor form. |
| fumes | A blend of soot-like particles mixed with vapors |
| gas | A state of matter different from liquid or solid. Gases are not formed by evaporation of liquids, as are vapors. Gases must not be confused with vapors or fumes. |
| methacrylates | type of acrylic monomer (cross- linking) that has very good adhesion to the natural nail plate and polymerizes in minutes; used to make alliquid/powder systerns and at least one type of UV gel. |
| methyl methacrylate monomer (MMA) | A substance in wide use around the world for many applications, such as bone repair cement for implantation into the body. |
| Monomers | Molecules that can polymerize to form long polymer chains. |
| nail primer | A substance that improves adhesion; used on the natural nail prior to product application to assist in adhesion. |
| oligomer | Short chain of monomers that is not long enough to be considered a polymer. |
| overexposure | Prolonged, repeated or long term exposure that can cause sensitivity. |
| over-filing | Prolonged, repeated or long term exposure that can cause sensitivity. |
| photoinitiator | A chemical that in combination with resins and the proper curing lamp causes UV gels to cure. |
| plasticizers | Ingredients used to keep nail enhancement products flexible. |
| Polymers | Substance formed by combining many small molecules (monomers) or oligomers, usually in extremely long, chainlike structures. |
| polymerization | Also known as curing or hardening: a chemical reaction that creates polymers. |
| simple polymer chains | The result of a long chain of monomers that are attached from head to tail. |
| thermal initiators | Ingredients that use heat as an energy source for starting chemical reactions, such as polymerizing monomers into polymer. |
| UV stabilizers | Ingredients that control color stability and prevent sunlight from causing fading or discoloration. |
| Vapors | Vapors are formed when liquids evaporate into the air. |
