The
coating has a plasticizers (e.g. camphor). This links polymer chains,
spacing them to make the film flexible after drying. That way it resists
cracking or flaking caused by the natural movement of the nail.
History
Nail
polish was used in the ancient world. In China it started off being
made from a combination of beeswax, egg whites, gelatin, vegetable dyes,
and gum arabic. The Chinese would dip their hands in an oil for several
hours their finger nails would turn red or pink.In Ancient Egypt henna
was used. The henna stained their fingernails orange, which turned dark
red or brown after the stain matured. In 1300 BC, the colour of the nail
polish reflected social rank. The colours gold and silver were
favoured; later, black and red were the favoured colours. Red is the
colour Cleopatra wore.
By the turn of
the 9th century, nails were tinted with scented red oils, and polished
or buffed with a chamois cloth, rather than simply polished.In the 19th
and early 20th centuries, people pursued a polished rather than painted
look by massaging tinted powders and creams into their nails, then
buffing them shiny. After the creation of automobile paint, Cutex
produced the first modern nail polish in 1917. Synthetic nail polish was
introduced in the 1920s in Paris.
Artificial nails
The
artificial nails are not a replacement, but an extension for natural
nails. There are two main approaches to creating artificial nails–tips
and forms.
Tips are made of
lightweight plastic plates that are nail-shaped. They are glued on the
end of the natural nail and liquid acrylic is then applied over the
entire nail.
Forms are fitted over
the nail. Then an artificial nail is molded out of acrylic. Then the
form is removed and the new nail shaped and buffed to a shine.
Acrylics
This
is a mixture of a powder and a liquid. The mixture starts to harden in
30–40 seconds after application and gets to its final hardness in
fifteen minutes. Powder and liquid acrylics can be removed by using a
variety of solvents (usually acetone is used). Usually it takes 15 to 20
minutes to remove the nail.
UV topcoat
Another
material, commonly called "UV Top Coat" (in correct terms a polymer
resin), hardens under ultraviolet light. These can show a wider range of
properties (flexibility, strength, etc.) but may be more expensive.
