The Chemistry of Lotion


My chemistry of … is lotion. Lotion is what everyone needs, it provides moisture to your skin. I mainly chose lotion because I want to know what I am putting on my skin. My life is affected by lotion because without it I would be flaky which is very unhygienic.

Composition of ...

    • Sodium Dioxide (NaOH)
    • Water (H2O)
    • Titanium Dioxide (TiO2 )
    • Petroleum (CnH2n+2)
    • Glycerin (C3H8O3)
    • Citric Acid (C6H8O7)
    • Butylene Glycol (C4H10O2)

Main Chemicals, Compounds, Components

    • Petroleum (CnH2n+2)- another name for it is Mineral Oil. It is dug up from the ground and refined. What it does is trap the moisture to your skin, which can clog your pores. It’s naturally occurring, but unfortunately it has become harder to find since the demand for it has increased. It is formed when plants or organisms are trapped in layers of sediment for millions of years!
    • Water (H2O)- covers about 70 percent of the earth. Found all over rivers, waterfalls, oceans, and etc. Some scientist believe that it came from a different planet.Water consists of two hydrogens and one oxygen. Water is the main ingredient in lotion.What it’s meant to do is to hydrate and moisturize the skin. Water actually makes up 95 percent of your brain, 82 percent of your blood, and 90 of your lungs.

Chemistry's Role

Petroleum and water are combined into a mixture. These two elements don’t combine. Water needs a charged element,since oil is uncharged it can’t combine. In order to fix this problem they add surfactant, which attracts both water and oil. Surfactant has two parts, which it allows it to bind with both water and oil.This process is also used on many other products. It is very important in the process of making lotion.

Background Research

First, you would combine the oil and water together. Then you would add the fragrance to the mixture. After that you would add colorants to the mixture. Place that into a jar and you have your lotion. Lotion can be made at home or in special laboratories. Lotion is meant to moisturize broken, cracked, and dried skin. Evidence shows that forms of lotions have been around since 3500 BC. Of course we have modernized lotion to what it is today.
