Chemical formulations are mixtures of different chemical substances, designed to achieve specific properties or functions. These formulations can include pure chemicals, additives, and solvents, and are commonly used in products like medicines, cosmetics, and cleaning agents. The goal is to create a stable and effective product that meets desired performance criteria. In the field of chemistry, understanding chemical formulations is essential for developing new materials and improving existing ones. Scientists often use techniques like spectroscopy and chromatography to analyze and optimize these formulations, ensuring they are safe and effective for their intended use.
