= Introduction: =  Many people today are using make-up that has natural products. For example people are turning toward Bare Mineral products instead of using the heavy and creamy make up that can clog your pores or not blend as well as mineral make up. Bare minerals make up helps make up look natural instead of looking like you have tons of make up on. Bare minerals has become a very popular product and while many women use it on a regular basis, they may not know what is the make up they use everyday. We are here to tell you what makes this makeup popular. Each product Bare Minerals make is made differently from the next. The company focuses on each face and the need each face has, which is already very different from other make up brands. While other make up brands, such as L’Oreal or Neutrogena say they have minerals in the make up it is add, unlike Bare Minerals where the make up contains only 5 ingredients. Many people use Bare Minerals because of the natural and glowing look women get from a simple yet powerful 5-ingredient makeup. Being able to use make up everyday that makes it look natural is very important to women. Women also care about what it included in the make-up; many people may not know that 2 of the 5 ingredients are sunscreen protective ingredients. The 2 ingredients are a natural sunscreen that gives you sun protection all day long, while wearing the make-up. While the company started off with only 5 basic colors, it has grown to having 15 different shades to fit each person’s skin color need. Having some many different shades to fit each person’s individual needs helps people continue to come back to this make up. The following are the 5 ingredients that we will be discussing in our Wiki product that continue to help make bare minerals grow each year. Titanium Dioxide, Zinc Oxide, Bismuth Oxychloride, Mica, Iron Oxides.

Chemical Principles:
 There are five chemicals that make up the make Bare Minerals by Bare Essentials. Bare Minerals is composed of: Titanium Dioxide, Zinc Oxide, Bismuth Oxychloride, Mica and Iron Oxide. All of these ingredients are naturally occurring. In this section we will explore the five ingredients and discover how they are made up, what they do for the skin, and if there is any danger in using them. Titanium oxide is a white pigment that is used in cosmetics to block UVA and UVB rays, as a white pigment and an opacifier. (2) “Titanium (IV) oxide or titania, is the naturally occurring oxide of titanium” (1). The Chemical formula for Titanium Dioxide is TiO2. “It is a white, opaque and naturally- occurring mineral found in two main forms: rutile and anatase.” (2). Titanium dioxide in the form rutile and anatase are both bound to impurities but through a chemical process these impurities are removed leaving TiO2 free of impurities. There are no dangers in Titanium Dioxide despite the claims of causing cancer. When tested Titanium Dioxide did not show any signs of being carcinogen (2) (this will be further discussed in societal impacts). Zinc Oxide’s chemical formula is ZnO. It is a naturally occurring element. Zinc Oxide is also a white powder that is used to block UV rays. ZnO has the ability to retain moisture and protect the skin because it is insoluble in water (3). Zinc Oxide is not dangerous in when used as a cosmetic. Zinc Oxide becomes dangerous when it is in gas form and is inhaled. If this happens people should seek medical help immediately and the chance of recovering is extremely likely. (4) Bismuth Oxychloride’s chemical formula is BiOCl. Although Bismuth by itself would be chemically harmful when combine with oxygen and chloride it is safe to use as a cosmetic. It is used to provide a glow to the skin. (5) This is the chemical that gives the skin a matte look or a shiny finish. “Bismuth occurs naturally, but in very small amounts. Most of the bismuth produced in the USA is as a by-product from refining lead, tin, copper, silver and gold ores” (6). So chemically the bismuth oxychloride that is used in Bare Minerals is a result of by-products due to the limited amount of Bismuth available. Mica occurs naturally in the form of rocks and has the ability to break apart in sheets. Due to this physical property Mica is very translucent and is an ingredient used due to its sheer texture and it allows the skin to appear smooth, soft and even. There are no dangers known as a result of using Mica in cosmetics. Iron Oxide is the mineral that is used to produce the color in Bare Minerals. Iron oxide comes in many forms but there are three main forms that are used for cosmetics. Iron Oxide is classified into the groups red, black and yellow (7). Color is created by a mixture of these different groups of Iron oxide. “Color tone depends on the temperature, concentration, pH, and radius of the particle when manufactured.” (7)

Societal Impact:
Mineral make up has impacted society in a major way. Before mineral make up was introduced, many women used make up that is made up of chemical-based products. Every day, most women put on make up that could (most likely) have a negative affect on their appearance in the long run. "Unfortunately, chemical-based makeup creates an environment where bacteria can infect the skin. Additionally, the additives and oils can irritate and actually damage skin" (8). With mineral make up such as Bare Minerals, however, women no longer have only the option of harmful chemical-based products. Mineral make up, as we've shown, is made up of only five ingredients - none of which are harsh chemicals, or are man made. In addition, "Mineral makeup is manufactured with all natural minerals that are purified and ground into tiny particles that can be used on the skin as foundation, concealer, eye shadow, and blush" (8). So now with mineral make up on the market, people in society who wear make up have the opportunity to choose whether or not to wear make up that has harsh chemicals in it or to wear make up that has five simple, natural ingredients. Hopefully now that we've introduced you to mineral make up, you will be informed and will be able to make an educated decision the next time you go to buy make up. After all, putting make up on your skin may have more of a long-term impact than you think!
