why should you learn about nail product chemistry?
you will be better equipped to solve problems when things go wrong, you will have a deeper understanding about how professional products work, you are less likely to be fooled by improper claims and advertising
what is the result of over-filing the nail?
damaging the nail plate and underlying sensitive tissues of the nail bed, and lifting of the nail bed.
What is overexposure?
prolonged, repeated,or long-term exposure that can cause sensitivity.
what nail service substance has been banned in many countries but is still used in most salons?
Methyl methacrylate monomer (MMA)
a substance that improves adhesion; used on the natural nail prior to product application to assist in adhesion
nail primer
what is a gas?
a state of matter consisting of particles, which have neither a defined volume nor defined shape.
the majority of chemicals are only safe if...?
they are used carefully and properly
Methacrylates, Acrylates, and Cyanoacylates and types of what?
Acrylics
how can you protect your health while giving acrylic nail services?
wearing a dust mask, using a ventilation system, wearing gloves
a chemical reaction that creates polymers (AKA curing)
polymerization
what is a vapor?
Explain the difference between gases, vapors and fumes found in a nail salon and why it's important to distinguish among them.
A gas is a substance that is in the gaseous state at room temperature and pressure.
A vapor is the gaseous form of a substance that is a liquid or solid at room conditions.
Fumes are fine solid particles that are suspended in the air.
Distinguishing is important for ventilation and safety vapors can carry harmful chemicals that can be inhaled or make contact with skin.
Why do some people's nails turn yellow after using nail polish for a long time
Some nail polishes contain color pigments or formaldehyde resin that can react with the keratin in nails. Over time oxidation or chemical staining from these ingredients can cause the nails to appear yellow.
what are some examples of polymers?
Teflon, nylon, hair, and wood
a substance wide in use around the world for many applications, such as bone repair cement for implantation into the body
methyl methacrylate monomer (MMA)
what is a fume?
a blend of soot-like particles mixed with vapors
what chemical safety practices should nail technicians follow to minimize exposure to harmful substances?
good ventilation, using masks, storing and labeling products properly, and reading SDS sheets for hazards.
whats the main difference between acid and non-acid primers?
acid primers are more rough for stronger bonding while non-acid is more gentle.
adhesion is the result of when...?
the molecules on one surface are attracted to the molecules on another surface
a specialized acrylic monomer that has excellent adhesion to the nail plate and polymerizes in seconds; used to make nail wraps and adhesives
cyanoacrylates
describe the differences between gases, vapors, and fumes
gases do not come from liquid, vapors result from evaporation, and fumes have large particles
what happens if monomer and polymer are mixed in the wrong ratio?
The product may become weak, too soft, or prone to lifting
how can poor nail prep cause lifting?
who made the following statement? : "All substances are poisons; there is none that is not a poison. only the dose differentiates a poison and a remedy"
Paracelsus, a famous sixteenth-century physician (check page 127!)
