Pure Chemistry:
* Understanding the chemistry of hair: This involves studying the chemical composition of hair, including its proteins (keratin), lipids, and water content. This knowledge is crucial for understanding how different ingredients interact with hair and affect its structure.
* Designing and synthesizing ingredients: Chemists create new molecules or modify existing ones to develop ingredients with specific properties, like humectants (attract moisture), emollients (soften hair), or protein fillers.
Applied Chemistry:
* Formulating the shampoo: This involves combining ingredients in specific proportions and using the principles of chemistry to create a stable and effective shampoo. This includes understanding the role of surfactants (cleansing agents), pH control, and viscosity.
* Testing the shampoo: Scientists conduct rigorous tests to evaluate the shampoo's effectiveness in hydrating, repairing, and protecting dry or damaged hair. This involves assessing its cleansing ability, ability to improve hair texture, and potential for irritation.
* Packaging and shelf life: The shampoo's packaging and storage conditions are also guided by chemistry to ensure its stability and effectiveness over time.
In essence, developing a shampoo requires a deep understanding of the chemistry of hair and the principles of formulating products, which makes it a field that blends both pure and applied chemistry.
