History Nail polish may have originated with the Chinese in 3000 B.C. The Japanese and Italians are thought to have been the first ones to use nail polish. The Chinese used a color lacquer, made from a combination of Arabic gum, egg whites, gelatin and beeswax.
benefits Most females love to decorate their nails with nail polish in attempts to beautify their hands. What most females do not recognize is that there are actually benefits of nail polish. Nail polish together with other cosmetics can make a woman feel good-looking and confident inside and out. If you have flawed or unappealing finger nails or toenails, nail polish can help disguise that. Obviously, you will forever want to keep your nails clean for hygienic reasons, but nail polish can cover up unsightly flaws.
Chemical Make-up The primary ingredient in nail polish is nitrocellulose 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. 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. Finally, the polish must have a color. Early polishes used soluble dyes, but today's product contains pigments of one type or another. Choice of pigment and its ability to mix well with the solvent and other ingredients is essential to producing a good quality product.
1. Nail polish is made by combining nitrocellulose and plasticizers with color pigments. The mixing is done in a "two-roll" differential speed mill, which grinds the pigment between a pair of rollers that are able to work with increasing speed as the pigment is ground down. The goal is to produce fine dispersion of the color. 2. Once the pigment mass is prepared, it is mixed with solvent in a stainless steel kettle. The kettle has a water-jacket to facilitate cooling of the mixture.
How To Make Open the bottle of clear nail polish. Be sure to pick a clear nail polish with a consistency you like, but refer to Step 6 below if you are using an older or lumpy bottle of nail polish. Place the end of the funnel into the bottle of clear nail polish and place a small scrap of paper in the bottom of the funnel to block the hole. Pour crushed eye shadow or makeup pigment into the funnel. To crush your eye shadow, place in a sealed plastic baggie and press gently on the eye shadow until it is a lump-free, powdery consistency. Add a small amount of fine glitter to the funnel mixture if you wish. Remember, a little bit of glitter goes a long way. Mix the glitter and eye shadow/ pigment carefully before removing the scrap of paper, allowing the powder to enter the bottle. Take the funnel out, replace the cap on the nail polish and shake well for two minutes. If the color is not exactly to your liking, try adding more eye shadow/pigment or glitter. You may find that the nail polish you are using is thick or lumpy. Pour a few drops of nail polish remover into the nail polish bottle and shake for one minute to thin the nail polish.
Egyptians make-up Ancient Egyptians used a form of henna to paint their nails and color their hair. The color and condition of nails have long been an indication of social status. The coloring used by Ancient Egyptian in this type make up was achieved by the use of henna. Henna is a dye obtained from the leaves and shoots of the henna shrub which is native to tropical and subtropical regions of Africa Dried, ground, sifted henna leaves are easily worked into a paste To create the make up and cosmetics using henna the leaves or shoots were ground on a palette then mixed with water to form a paste. Henna was also used as a healing plant and for cleansing and cooling the skin Henna was used in ancient Egypt to stain the fingers and toes of Pharaohs and nobles prior to mummification
