• Write a report on the Chemistry involved and the type of Chemical reaction involved in the following process from our day to day to life regarding the following: 1. Soap and detergents 2.Hair Colour
Answers
1. Hot caustic alkali solution, such as caustic soda (sodium hydroxide), acts on natural fats or oils, such as tallow or vegetable oil, to produce sodium fatty acid salt (soap) and glycerin (or glycerol). This saponification reaction is the basis for all soapmaking.
2.The bleach reacts with the melanin in the hair, removing the color through an irreversible chemical reaction. The bleach oxidizes the melanin molecule.The peroxide is used in an alkaline solution, which opens the hair shaft to allow the peroxide to react with the melanin.
Answer:
Soaps are chemically classified as salts of fatty acids because of the presence of an ionic, or polar head, and a nonpolar glyceride tail. The head is composed of positively charged sodium ions and negatively charged oxygen ions, while the tail is a fatty chain.
