Introduction: Cosmetics are generally defined as products applied externally to improve appearance. The purpose-enhancing beauty defines cosmetic use, as opposed to painting the system for religious, ritual, or medicinal purposes. With the exception of “permanent cosmetics,” a late 20th Century innovation, cosmetics’ temporary nature separates them from long lasting body alterations such as tattoos, piercings, or scarification. Because cosmetics are developed to enhance beauty and increase facial attraction, cosmetic use has always been a coming of age. In the 1920s flappers battled their parents not only for the right to smoke and dance in community but for the right to wear makeup. In the 1950s, however, cosmetic manufacturers saw gold in the burgeoning baby-boom youth market and the competition was on. Cosmetics: Cosmetics were in wide use in the Roman Empire, but they vanished from much of Europe with the fall of the Roman Empire (5th century AD) and did not reappear until the Middle Ages, when Crusaders returned from the Middle East with cosmetics and perfumes. By the 18th century they had come into use by nearly all social classes. Modern cosmetics include skin-care preparations; foundation, face powder and rouge (blusher); eye makeup; lipstick; shampoo; hair curling and straightening preparations; hair colors, dyes, and bleaches; and nail polish. Related products include antiperspirants, mouthwashes, depilatories, astringents, and bath crystals. The first historical proof of cosmetics usage is found in Ancient Egypt around 4000 BC. The Ancient Greeks and Romans also used cosmetics. The Romans and Ancient Egyptians used cosmetics containing mercury and often lead. In the western world, the advent of cosmetics was in the middle Ages, although typically restricted to use within the upper classes. Cosmetic use was frowned upon at some points in history. For example, in the nineteenth century Queen Victoria publicly declared makeup improper. It was viewed as vulgar and acceptable only for use by actors. By the middle of the 20th century, cosmetics were in widespread use in nearly all societies around the world. Chemicals in Cosmetics: 1,4-dioxane 1,4-dioxane is not listed on ingredient labels. It is a petroleum-derived toxic established in the manufacture of shampoos, body wash, children’s bath products and other sudsing cosmetics. The International Agency for Research on Cancer (IARC) has ranked it as a possible carcinogen, and the National Toxicology Program (NTP) has identified it as a reasonably anticipated carcinogen. Ethylene Oxide Ethylene oxide is discovered in fragrances and is widely used to manufacture popular brands of shampoo. It is classified as a known human carcinogen and is one of the 48 chemicals that the National Toxicology Program (NTP) identifies as mammary carcinogens in animals. Conclusion: The entire cosmetic industry is in a buyer beware state of alert, thanks to the latest additions to the melting pot of chemicals and pollutants in skin care, above and beyond the usual parabens. Consumers are warned by experts to put on the watch list any makeup which contains synthetic coloring ingredients, emulsifiers, leads, copolymer, triclosan, and “urea as a preservative.” Also contributing to the chemical compounds are phthalates, formaldehyde, and petroleum.If you want to know more about this,you can visit the Chemistry products in this you will get the full details of chemicals.
