here is about nail polish and make-up its kind of a good place to look at......and this is all about how nail olilsh is made ..

Unlike many other cosmetics that have a history of hundreds or even thousands of years, nail polish (or lacquer, or enamel) is almost completely an invention of twentieth century technology. Nail coverings were not unknown in ancient times—the upper classes of ancient Egypt probably used henna to dye both hair and fingernails—but essentially, its composition, manufacture and handling reflect developments in modern chemical technology.
Modern nail polish is sold in liquid form in small bottles and is applied with a tiny brush. Within a few minutes after application, the substance hardens and forms a shiny coating on the fingernail that is both water- and chip-resistant. Generally, a coating of nail polish may last several days before it begins to chip and fall off. Nail polish can also be removed manually by applying nail polish "remover," a substance designed to break down and dissolve the polish.
Raw Materials
There is no single formula for nail polish. There are, however, a number of ingredient types that are used. These basic components include: film forming agents, resins and plasticizers, solvents, and coloring agents. The exact formulation of a nail polish, apart from being a corporate secret, greatly depends upon choices made by chemists and chemical engineers in the research and development phase of manufacturing. Additionally, as chemicals and other ingredients become accepted or discredited for some uses, adjustments are made. For example, formaldehyde was once frequently used in polish production, but now it is rarely used.
The primary ingredient in nail polish is nitrocellulose (cellulose nitrate) cotton, a flammable and explosive ingredient also used in making dynamite. Nitrocellulose is a liquid mixed with tiny, near-microscopic cotton fibers. In the manufacturing process, the cotton fibers are ground even smaller and do not need to be removed. The nitrocellulose can be purchased in various viscosities to match the desired viscosity of the final product.
Nitrocellulose acts as a film forming agent. For nail polish to work properly, a hard film must form on the exposed surface of the nail, but it cannot form so quickly that it prevents the material underneath from drying. (Consider commercial puddings or gelatin products that dry or film on an exposed surface and protect the moist product underneath.) By itself or used with other functional ingredients, the nitrocellulose film is brittle and adheres poorly to nails.
Manufacturers add synthetic resins and plasticizers (and occasionally similar, natural products) to their mixes to improve flexibility, resistance to soap and water, and other qualities; older recipes sometimes even used nylon for this purpose. Because of the number of desired qualities involved, however, there is no single resin or combination of resins that meets every specification. Among the resins and plasticizers in use today are castor oil, amyl and butyl stearate, and mixes of glycerol, fatty acids, and acetic acids.
The colorings and other components of nail polish must be contained within one or more solvents that hold the colorings and other materials until the polish is applied. After application, the solvent must be able to evaporate. In many cases, the solvent also acts a Read more: How nail polish is made - material, manufacture, making, history, used, components, composition, structure, product, Raw Materials, The Manufacturing Process of nail polish, Quality Control http://www.madehow.com/Volume-1/Nail-Polish.html#ixzz0pEmJAwS4
