Nail polish

Nail polish (also known as nail polish or nail polish) is a kind of paint that can be applied to human nails or toenails to decorate and protect nail plates. The formula has been modified many times to enhance its decorative effect and to prevent cracking or peeling. Nail polish is made up of organic polymers and mixtures of other ingredients, depending on the brand.

Nail polish originated in China, and its history can be traced back to 3000 BC. Around 600 BC, during the Zhou Dynasty, the royal family tended to use gold and silver. However, red and black eventually replaced these metallic colors and became Royal favorites. In the Ming Dynasty, nail polish was usually made from beeswax, egg white, gelatin, vegetable dye and Arabia gum.

In Egypt, lower classes wear light colors, while upper class nails are painted reddish brown with henna. The mummified King's nails were also painted with henna.

Color nail polish did not appear until 1920s. The early nail polish formula was made from lavender oil, carmine, tin oxide and bergamot oil. It is more common to polish the nail with colored powder and cream, and then polish it until it shines. A polished product sold for about this time is Graff's Hyglo nail polish.

Nail polish is made up of film-forming polymers dissolved in volatile organic solvents. Nitrocellulose dissolved in butyl acetate or ethyl acetate is common. This basic formula has been extended to include the following:

Plasticizers can produce non brittle films. Dibutyl phthalate and camphor are typical plasticizers.

Dyes and pigments. Representative compounds include chrome oxide green, chromium hydroxide, ferrocyanide, tin oxide, titanium dioxide, iron oxide, carmine, ultramarine and manganese violet.

Opalescent pigment. Mica, bismuth oxychloride, natural pearls and aluminum powder can give the color glittering color.

Sticky polymers ensure that nitrocellulose adheres to the nail surface. One modifier used is toluenesulfonamide formaldehyde resin.

A thickener is added to keep the bubble particles in suspension when they are in the bottle. The typical thickener is potassium stearate Lithium Montmorillonite. Thickeners exhibit thixotropy. Their solutions are viscous at rest, but they flow freely under agitation. This duality facilitates the application of a recently shaken mixture, which causes the film to harden rapidly.

When the dry film is exposed to sunlight, UV stabilizers can resist color changes. The typical stabilizer is benzophenone-1.

Gel polish is a nail polish made of methacrylate polymer and is durable. Similar to traditional nail polish, it is applied to nails, but it will not dry. It is cured under UV light or UV LED. Regular nail polish formulations usually last two to seven days without fragmentation, while proper application and family care can last for two weeks. Gel polish is harder to remove than ordinary nail polish. Nail removal is usually done by immersing fingernails in pure acetone (most of the solvents used in nail polish remover) for five to fifteen minutes (depending on the formula).

Traditionally, nail polish has been made from transparent, white, red, pink, purple and black. Nail polish can be of many colors and shadows. In addition to pure color, nail polish has developed a range of other designs, such as cracks, flashes, flakes, blotches, irises and holograms. Diamond or other decorative arts are often used for nail polish. Some polish is put on the advertisement to promote the growth of nails, make nails stronger, prevent nails from cracking, cracking / splitting, and even stop biting nails.
