2. What is mascara?Definition of Mascara-Mascara is a type of
cosmetic applied to the eyelashes. It serves tothicken and define
the eyelashes and may also color, lengthen, or curlthem, depending
upon the type. Its usually sold as a liquid cosmetic in atube and
applied with a round brush called a wand. However, cream andcake
versions also exist.History of Mascara-Surprisingly mascara has
been around sinceancient times. Even Ancient Egyptiansand Romans
have been known to be the first toever use mascara. A sanskrit
called the KamaSutra from the fourth century contains an eyemakeup
recipe that they used in the same way wecontinue to do today. 3.
Main IngredientsIron OxideChromium OxideCarbon BlackBeeswax 4. Iron
OxideIron oxides may have the chemical formula of FeO (IronII
Oxide) or Fe2O3 (Iron III Oxide), depending on thecharge of the
iron atoms. Balancing these compoundsbased on the charge of the
atom is something that wehave learned to do in class this year.Iron
Oxide is made through oxidation,something that we have also studied
inclass. The oxidation occurs when the ironis exposed to the air.
5. Chromium OxideChromium (II) Oxide (CrO) is an inorganiccompound
made up of oxygen and chromium. Thiscompound is made by heating
chromium hydroxide(Cr(OH)3). Chromium oxide is a black powder until
itcrystalizes in the rock salt structure and is used inmascara. 6.
Carbon Black andBeeswaxCarbon Black (CH4) is also a fine black
powderused in mascara. This compound is formed byincomplete
combustions of hydrocarbons.Carbon black is not only used in
mascara butalso things such as printer ink, tires, and manyrubber
products.Beeswax (C15H31CO2C3H61) is a big ingredientis mascara as
well. Beeswax is made up ofalkyl esters and carbohydrates such
asglucose and sucrose. 7. ChemistryAnother way that chemistry ties
into mascara is the waythat there are two types of mascara.Mascaras
that are hydrophilic, which are soluble inwater, are not water
proof. These types of mascara haveweak hydrogen bonds.The other
type of mascara is hydrophobic whichmeans this type of mascara is
waterproof. This type hasstrong hydrogen bonds and is non polar. 8.
