Which step of disinfection eliminates most microorganisms?
Disinfection
What is the technical name for the natural nail?
Onyx
What type of gels are are formulated to overlay the natural nail and can be removed with acetone?
Soft gels
What is the name of the monomer that has been banned in the US from being used in salons? (acronym is ok)
Methyl methacrylate monomer or MMA
Overexposure to nail products can cause what?
Sensitivity or allergies
What is the difference between cleaning and sanitizing?
Cleaning is a mechanical process of removing dirt, debris and many germs. Sanitizing is a chemical process for reducing the number of disease-causing germs in cleaned surfaces to a safe level. (Soap & water vs hand sanitizer)
Where is the hyponychium?
The hyponychium is the slightly thickened layer of skin that lies between the fingertip and the free edge of the nail plate
A chemical reaction that happens during the curing process is an exothermic reaction. How does this effect the client?
Clients can experience an uncomfortable amount of heat.
Trillions of molecules must react to make just one sculptured nail. Those molecules join together in very long chains. What are those chains called?
Polymers
What is the purpose of the "position stop" on a nail tip?
The position stop helps determine where the tip should be placed
Which process destroys all microbial life?
Sterilization
What is the area where the nail plate cells are formed called?
Matrix
Generally, non-self-leveling building gels have what viscosity?
Thicker viscosity
What is the substance (that are in every type of nail enhancement) that speeds up the chemical reaction by making initiators work more efficiently?
Catalysts – this is the reason nail enhancements harden so quickly
The stress area, where the natural nail grows beyond the finger and becomes the free edge, needs extra product and strength to support the artificial extension. What is the name of the "protection" we add to that area when sculpting nail enhancements?
Apex
What is the common name for sodium hypochlorite?
bleach
Where is the proximal nail fold?
The proximal nail fold is the entire flap of skin covering the matrix, extending from the edge of the visible nail plate to the first joint of the finger
What is an inhibition later or oxygen inhibition layer?
Uncured gel that create a tacky surface left on the nail after the gel has cured.
What is the name for the short chain of monomers that has had the growth of it's chain halted before it became a full polymer? This is the ingredients in UV gels that gives their sticky consistency.
Oligomer
What is "grit" a measurement of when referring to hand files or buffers?
The number of grains of sand per square inch
Which federal agency created standards that address issues relating to your right to know about any potentially hazardous ingredients contained in the products and how to avoid these hazards?

The lunula is the whitish, half-moon shape underneath the base of the nail plate. It is the visible part of what?
The matrix
What is the name of the molecule in gel products that creates a reaction when exposed to UV light?
Photoinitiator
Simple polymer chains can easily be unraveled with solvents and force. To overcome these problems, nail enhancements use a special monomer called ______. This type of monomer creates a net-like polymer that is much stronger.
Cross-linker
What is the difference between fumes and vapor?
Vapors are formed when liquids evaporate. Fumes are vapors mixed with soot-like particles.
