Transcript of Chemical Reactions Regarding Makeup

The Process: The Ingredients Makeup Depending on the different types of products that you are using different reactions occur. Makeup can be very complex because of the types of chemicals you are using. Environmental Impact Because of so much chemicals in makeup there are some health risks. Some of these chemical reaction have caused countries to ban the use of these chemicals. By: Jodelle Makeup is generally mixtures of chemical compounds, some being derived from natural sources and many being synthetic History Evidence proves that makeup has been dated back all the way to ancient Egypt and Greece.
Mainly in Egypt they used castor oil as lip balm while the Romans used beeswax, olive oil and rosewater for skin creams.
Now today makeup is used much more especially in the western part of the world. There are many different things in makeup. Some are: Titanium Dioxide
Iron Oxide
Shea Butter
Castor Oil
Etc. Some of the synthetic colours are listed in codes, these codes you will find on the back of any of your cosmetics. For example the pigment red could be found in lipstick, it can come from synthetically derived pure iron oxide (common iron rust). Most leading brands use more economical synthetic colours. Some synthetic colours can contain up to 10 parts per million of lead / 3 parts per million of arsenic. The FDA (Food and Drug Association) has tested the ingredients in these products and have realized that it can not harm our bodies so far. Some of the chemical equations in makeup is: C7H6O2 - Benzoic Acid Ester which this is found in waterproof cosmetics.
Sodium hydroxide - NaOH which is used as a base.
Titanium Dioxide - TiO2 which is used for pigmentation etc.
Silicone - Si which is used in lip products.
Iron Oxide - FeO which is used for colour or pigmentation as well. Mascara can be manufactured in one of two different ways: with water (emulsion) and without water (anhydrous). In the emulsion process, thickeners are combined with water to create a creamy base. Waxes and emulsifiers are blended and heated, pigments are added and the mixture is combined with the creamy base. With the anhydrous process, all ingredients are blended together in a tank and heated. There are many different ways to make makeup for different types of products, i will be showing two ways. Continued... Lipstick

The process for manufacturing lipstick requires that the ingredients be melted and mixed in three separate solutions: solvents, oils, and waxes and fats. After the mixtures are blended, some manufacturers use a vacuum to remove any trapped air. The molten lipstick is poured into molds, which are then refrigerated. For Example: In lipsticks, there base are slippery chemical compounds called esters, which are formed by reactions between alcohols and acids. Esters are added to make a lipstick shine and make the rather dry oil-and-wax mixture glide onto lips more smoothly. Continued... In mascara they rely on heavy bases such as paraffin and wax. Not only to keep lash darkening pigments stuck on the lashes when tears or water touch the eyelashes. Many people think that wearing makeup cant harm the environment, but there wrong. When you wear makeup up to 60% gets absorbed into the bloodstream, and when we wash our bodies the chemicals in the products then goes into the water supply system. Some Are: Parabens, phenols, phthalates, dioxanes and phytoestrogens are some of the common chemicals in moisturizers, sunscreens, lotion and face powders. Also when we think were just throwing away an empty bottle, most of these bottles are not biodegradable which is not good for our environment. Most cosmetic products are flammable, one of the WHIMS symbol is to the left. Other cosmetic products under HHPS are explosive as well. Dangers Some dangers in makeup are the side affects. Especially in old makeup because these chemicals after a while in the containers will form a bad chemical reaction and in due time could cause very serious allergic reactions and sometimes depending on the chemicals used in that product could even cause cancer.
