Nail polish, also known as nail varnish or nail enamel, is a lacquer used to decorate and protect the nail plates.

It serves both aesthetic and functional purposes in manicures and pedicures. The formula is designed to enhance decorative qualities while preventing cracking or peeling. Modern polishes consist of an organic polymer mixed with several other components. These additives provide specific colors, textures, and finishes.

The chemical mechanism of nail polish relies on a film-forming polymer dissolved in a volatile organic solvent.

Most standard polishes use nitrocellulose as the primary polymer. Other expensive options include cellulose acetates like CAB for better performance. Solvents such as butyl acetate or ethyl acetate allow the liquid to be applied easily. Once applied, the solvent evaporates, leaving a solid film behind. Additives like plasticizers, such as camphor, ensure the film does not become brittle.

Application often involves distinct stages to ensure durability. A base coat is applied first to strengthen the nail and restore moisture. This clear or pink layer helps the color adhere and prevents staining. Some base coats act as ridge fillers to create a smooth surface. After the color is applied, a top coat is used to create a hardened barrier. This clear layer prevents chipping and scratching while helping the color dry quickly.

Gel nail polish represents a different type of application and chemistry. Instead of air-drying, gel is cured under an ultraviolet (UV) or LED lamp. This process uses a catalyst, such as benzoyl peroxide, to trigger free radical polymerization. This chemical reaction creates a branched polymer matrix that is very hard and durable.

While regular polish lasts two to seven days, gel can last up to two weeks. However, gel is harder to remove and requires soaking in pure acetone for five to fifteen minutes.

The history of nail decoration spans thousands of years.

It originated in China around 3000 BCE. During the Zhou dynasty in 600 BCE, the royal house used gold and silver colors. Later, red and black became the royal favorites. In the Ming dynasty, mixtures included beeswax, egg whites, and vegetable dyes. In Egypt, lower classes used henna to achieve a reddish-brown color. Even mummified pharaohs were found with henna-painted nails.

In the Western world, social views on nail polish have shifted significantly. During the Victorian era, wearing makeup or nail color was often considered improper. In the 1920s, women used colorful nail products partly in rebellion against these customs.

Antoine de Paris, a French hairstylist, was a major pioneer during this era. He famously shocked the public by wearing a different color on every nail. By the 1940s, the fashion shifted from painting only the tips to painting the entire nail.

Modern nail art has expanded into a massive global industry. In 2012, nail polish sales in the United States reached a record US$768 million. This represented a 32% increase over the previous year. Today, artists use diverse tools like magnetic polish, nail pens, and stencils. They may also apply rhinestones or use "nail caviar," which are tiny microbeads.

These products allow for complex designs like holographic or iridescent finishes.

Nail polish is also a subject of scientific and professional interest. The ingredients used, such as methacrylates, are also utilized in medical and dental fields for surgical glue and dentures.

While some chemicals like acetonitrile are banned in the European Economic Area due to toxicity, many safe options exist. Even in non-traditional settings, such as professional baseball, catchers may use polish on the field. This shows how a simple cosmetic can connect to fashion, chemistry, and even professional sports.
