Soap Science Project
BACKGROUND:
The consumer products industry is one of the largest in the United States. One of the largest product categories within this industry is soap manufacturing and marketing. Each year companies such as Colgate Palmolive and Proctor & Gamble produce several billion dollars worth of soap products and employ scientific and technical workers to research and design new soap formulations. Soap products are essential to public health.
The soap molecule has a unique structure. It has a polar end, which attaches to water and dirt, and a non polar end, that attaches to oils and grease. Soap is made by mixing sodium hydroxide and water with lipids. Through a complex chemical reaction sodium hydroxide (a base) converts lipids (an acid) to soap. This process is called saponification. When lipids (acid) come into contact with the sodium hydroxide (base) the saponification process begins with the sodium hydroxide turning the lipid into a completely new substance that we know as soap.
