Nail polish (or as it is known outside of America Nail Varnish) is a lacquer that can be applied to the human fingernails or toenails to decorate and protect the nail plates. The formulation has been revised repeatedly to enhance its decorative effects and to suppress cracking or flaking. Nail polish consists of an organic polymer with various additives.After many years of use nail polish can weaken your nails. There is also another type of more advanced nail polish technology that is called gel nails. It is a more luscious, thick, and vibrant nail polish. There are many types of chemicals inside nail polish and should be used with caution. Another point about the industry of nail polish is that there are many nail polish brands that are competing to have the most business. In nail salons there is also a lot of completion between different nail brands and which is the cheapest, the most vibrant, the most expensive, or the best. The term " nail polish" can be defined as regular nail polish or as gel. Many people think of regular nail polish when they hear the term nail polish but scientists are making so many discoveries that it's hard to nail this whole cosmetic industry on one point.
Nail polish originated in China, and its use dates back to 3000 BC. Around 600 BC, during the Zhou dynasty, the royal house preferred the colors gold and silver. However, red and black eventually replaced these metallic colors as royal favorites. During the Ming dynasty, nail polish was often made from a mixture that included beeswax, egg whites, gelatin, vegetable dyes, and gum Arabic.
By the turn of the ninth century, nails were tinted with scented red oils, and polished or buffed. In the nineteenth and early twentieth centuries, people preferred a polished rather than a painted look by mixing tinted powders and creams into their nails, then buffing them until shiny. One type of polishing product sold around this time was Graf's Hyglo nail polish paste.
Nail polish consists of a film-forming polymer dissolved in a volatile organic solvent. Nitrocellulose that is dissolved in butyl acetate or ethyl acetate is common. This basic formulation is expanded to include the following:
- Plasticizers to yield non-brittle films. Dibutylphthalate and camphor are typical plasticizers.
- Dyes and pigments. Representative compounds include chromium oxide greens, chromium hydroxide, ferric ferrocyanide, stannic oxide, titanium dioxide, iron oxide, carmine, ultramarine, and manganese violet.
- Opalescent pigments. The glittery/shimmer look in the color can be conferred by mica, bismuth oxychloride, natural pearls, and aluminum powder.
- Adhesive polymers ensure that the nitrocellulose adheres to the nail's surface. One modifier used is tosylamide-formaldehyde resin.
- Thickening agents are added to maintain the sparkling particles in suspension while in the bottle. A typical thickener is stearalkonium hectorite. Thickening agents exhibit thixotropy, their solutions are viscous when still but free flowing when agitated. This duality is convenient for easily applying the freshly shaken mixture to give a film that quickly rigidifies.
- Ultraviolet stabilizers resist color changes when the dry film is exposed to sunlight. A typical stabilizer is benzophenone-1.
This type of nail polish is a clear, milky-colored, or opaque pink polish formula that is used specifically before applying nail polish to the nail. The purpose of it is to strengthen nails, restore moisture to the nail, and/or help polish adhere to the nail. Some base coats are marketed as "ridge fillers" which can create a smooth surface, and reduce the appearance the ridges that can appear on unhealthy nails or due to aging. Base coat may also help keep nails from being stained a yellowish color by colored polishes. It is also very common for base coats to have special oils to help the nail and its cuticles before the harsh nail polish gets painted on.
This type of nail polish is a clear colored polish formula that is used specifically after applying nail polish to the nail. It forms a hardened barrier for the nail that can prevent chipping, scratching and peeling. Many top coats are marketed as "quick-drying." Top coats can help the underlying colored polish dry quickly as well. Many top coats can also help with nail growth or nail repair. It gives the polish a more finished and desired look.
Gel polish is a long-lasting variety of nail polish made up of a type of methacrylate polymer. It is painted on the nail similar to traditional nail polish, but does not dry. Instead it is cured under an ultraviolet lamp or ultraviolet LED. While regular nail polish formulas typically last two to seven days before chipping, gel polish can last upwards of two weeks with proper application and home care. Gel polish can be more difficult to remove than regular nail polish. It is usually gently pushed off (often with a wooden stick) after soaking the nails in acetone (nail polish remover) for eight to fifteen minutes.
Matte polish is like regular polish, but has a purposely dull finish rather than a shine. It can be purchased as a regular base coat in ranges of different colors. Matte nail polish can also be found in a top coat. Matte top coat is most useful for painting over any dry base color, giving it a different appearance. The matte top coat polish will dull the shine from a regular base coat polish. Matte polish has become very popular through the years, particularly since it can be used in nail art applications, where designs can be created on the nail using the contrast of both shiny and matte surfaces.
Traditionally, nail polish started in clear, red, pink, purple, and black. Nail polish can be found in diverse variety of colors and shades. Beyond solid colors, nail polish has also developed an array of other designs, such as crackled, glitter, flake, speckled, iridescent, and holographic. Rhinestones or other decorative art are also often applied to nail polish. On-line tutorials are available. Some polish is advertised to induce nail growth, make nails stronger, prevent nails from breaking, cracking and splitting, and to even stop nail biting.
French manicures are designed to resemble natural nails, and are characterized by natural pink base nails with white tips. French manicures were one of the first popular and well known color schemes. French manicures may have originated in the eighteenth-century in Paris and were most popular in the 1920s and 1930s. One updated trend involves painting different colors as the tips of the nails instead of the basic white. The pink nail color with the white tip is considered elegant in a survey done at a house party, studies show that men like women with classic French tip more than a neon color like red or yellow. French tip nails take a lot of patience and passion to make and may need to be made with stickers, stencils or,with a basic tooth pick.
Social media has given rise to the nail art culture that allows users to share their pictures about their nail art. "WWD reports nail polish sales hit a record $768 million in the U.S. in 2012, a 32% gain over 2011, despite a cluttered market that seemingly sees a new launch each week." Several new polishes and related products came on to the market in the second decade of the twenty-first century as part of the explosion of nail art, such as nail stickers (either made of nail polish or plastic), stencils, magnetic nail polish, nail pens, glitter and sequin topcoats, nail caviar (micro beads) nail polish marketed for men, scented nail polish, and color changing nail polish (some which change hue when exposed to sunshine, and ranges which change hue in response to heat).[year needed] Pinterest, Instagram, and YouTube have been popular social media sites that many people around the world are posting their unique nail art. This is good for viewers because it can give them an idea of what kind of nail art they could try for themselves.
Nail polish in the Western World has traditionally been worn by women, going in and out of acceptability depending upon moral customs of the day. In Victorian era culture it was generally considered improper for women to adorn themselves with either makeup or nail coloring, with natural appearances being considered more chaste and pure. In the 1920s, however, women left corsets and long gowns behind, changed to simple loose-fitting dresses, and began to wear color in new makeups and nail products, partly in rebellion to such prim customs of their recent past. Since the 1920s, nail colors progressed from French manicures and standard reds to various palettes of color choices, usually coordinated with the fashion industry's clothing colors for the season.
Recently, men have begun to wear clear polish on their nails to protect them from breakage. In the past few years, a few men have also started to wear colored nail polish on their toenails, and some even on their hands, possibly arising from its use by rock music musicians or in Goth subculture. While pastel colors such as pink are not typically worn by men, colors such as black, gun metal, silver, olive green, or brown are more often seen. This is especially true in warm climate areas where open-toed shoes are worn and can mask damaged or disfigured nails.

Nail polish remover
Nail polish can be removed with nail pads or nail polish remover. The remover is an organic solvent, but may also include oils, scents, and coloring. Nail polish remover packages may include individual felt pads soaked in remover. Some removers are a bottle of liquid remover that can be used with a cotton ball or cotton pad. Others can be containers filled with foam that can be used by inserting a finger into the container and twisting until the polish comes off. Choosing a type of remover is determined by the users preference and often the price or quality of the remover.
The most common solvents are acetone. It is powerful and effective but can be harsh on skin and nails. Acetone can also be used to remove artificial nails, which are usually made of acrylic and gel nails. A less harsh nail polish removal is ethyl acetate, the active ingredient in non-acetone nail polish removers, which also often contain isopropyl alcohol. Ethyl acetate is generally the solvent in nail polish itself.
The health risks associated with nail polish are disputed. According to the U.S. Department of Health and Human Services), "The amount of chemicals used in animal studies is probably a couple of hundred times higher than what you would be exposed to from using nail polish every week or so. So the chances of any individual phthalate producing such harm [in humans] is very slim." A more serious health risk is faced by professional nail technicians, who perform manicures over a workstation known as a "nail table," on which the client’s hands rest - directly below the technician's breathing zone. In 2009, Dr. Susan Reutman, an epidemiologist with the U.S. National Institute for Occupational Safety and Health's Division of Applied Research and Technology, announced a federal effort to evaluate the effectiveness of downdraft vented nail tables (VNTs) in removing potential nail polish chemical and dust exposures from the technician's work area. These ventilation systems have potential to reduce worker exposure to chemicals by at least 50%. Many nail technicians will often wear masks to cover their mouth and nose from inhaling any of the harsh dust or chemicals from the nail products.
According to Reutman, a growing body of scientific literature suggests that some inhaled and absorbed organic solvents found in nail salons such as glycol ethers and carbon dilsufide may be human reproductive toxicants. These are responsible for effects including birth defects, low birth weight, miscarriage, and preterm birth.
Nail polish formulations may include ingredients that are toxic or effect other health problems. One controversial family of ingredient are phthalates, which are implicated as endocrine disruptors and linked to problems in the endocrine system and increased risk of diabetes in women. Manufacturers have been pressured by consumer groups to reduce or to eliminate potentially-toxic ingredients, and in September 2006, several companies agreed to phase out dibutyl phthalates. There are no universal consumer safety standards for nail polish, however, and while formaldehyde has been eliminated from some nail polish brands, others still use it.
Nail polish is considered a hazardous waste by some regulatory bodies such as the Los Angeles Department of Public Works. Many countries have strict restrictions on sending nail polish by mail.
