I think this web page is very interesting.

From this web page, I learn that chemistry plays a huge role in “effective cleaning”. Indeed, shampoos, soaps, detergents, etc are all products of chemistry reactions. Without Chemistry, how are we going to wash our bodies every day? Without Chemistry, wouldn’t our house be in a horrendous state? These are some of the reasons why I would love to learn Chemistry. I want to learn how people make soaps.
Finally, I suggest you watch this video, which shows how organic soaps are made. What an eye-opener!!!
