Chemistry
Pure chemistry involves research in pursuit of knowledge. Applied chemistry involves research directed toward a specific goal. Pure research can lead directly to an application; an application can exist before research is done to explain how it works.
I don't think it should be called carbon chemistry, if anything it should be hydrocarbon chemistry. It is because it involves anything with a C-H bond
Hydrogen ions a.k.a. protons
Developing a shampoo for dry or damaged hair involves both pure and applied chemistry. Pure chemistry focuses on understanding the fundamental chemical properties of ingredients, while applied chemistry involves using this knowledge to create effective formulations that address specific hair care needs.
