Although there is no singular formula for nail polish, most polishes contain the same basic components: film forming agents, resins and plasticizers, solvents, and coloring agents. Most nail polish companies use chemists and chemical engineers to research and test the best combinations of these materials. Over time, as new products become available, older ingredients are discarded. For example, formaldehyde was formerly be used in nail polish production, but is rarely used anymore.
The main ingredient in nail polish is nitrocellulose (cellulose nitrate). Nitrocellulose, a highly combustible material that is also used in making dynamite, creates a film that holds together other substances. It is made of liquid mixed with tiny cotton fibers. During the manufacturing process, the fibers are ground so small that they don't have to be removed from the product. It's also the main ingredient in cine film, or movie film. Nitrocellulose is key in creating a good nail polish. A hard film must form on the surface of the nail, but it can't form so quickly that it disables the material underneath it from drying. By itself, however, nitrocellulose is brittle and sticks to nails poorly, so other ingredients are needed to achieve a good coating. Nitrocellulose comes in different viscosities that can match the viscosity wanted in the final product.
Resins and plasticizers are added to the nitrocellulose in the nail polish -- to add flexibility and resistance to soap and water. Older versions of nail polish used nylon to achieve this effect. Although all nail polish needs this flexibility and resistance, there is no one resin or plasticizer that is universally used; instead manufacturers use combinations of amyl and butyl stearate, castor oil, glycerol, fatty acids and acetic acids.After nitrocellulose and resins and plasticizers are combined, the next ingredient to add to the mix are coloring pigments held together by solvents. While early nail polish contained soluble dyes, today's products are colored with pigments. The solvent must evaporate after the polish is applied to nails.
How does all of this chemistry apply to your use of nail polish? A basic knowledge of the chemical components of nail polish can help your nail polish last longer and save you some money in the long run. For example, have you ever thought about why you shake a bottle of nail polish before painting your nails? Since nail polish is a suspension product, meaning that colors can only be held together for a short time, shaking the bottle before use will help to restore settled particles to the suspension. An old bottle of polish will have too many settled color particles that will be difficult to restore to the suspension and reconstitute into the solvent. Additionally, refrigerating nail polish will slow down discoloration as a bottle of nail polish ages. Refrigeration will reduce the evaporation of solvents and will prevent pigments from caking together. http://www.ultraimports.com.au/
