What is the scientific study of the composition, structure, and properties of matter called?

The scientific study of the composition, structure, and properties of matter is known as chemistry. This field encompasses various aspects, including the understanding of how substances interact, combine, and change. It provides foundational knowledge that is crucial in various applications, such as cosmetic formulation, which is highly relevant to esthetics.

Chemistry plays a key role in understanding the ingredients used in skincare products, how they affect the skin, and how they can be combined to create effective formulations. For estheticians, knowledge of chemistry helps in making informed decisions about treatments and products, ensuring safety and effectiveness for clients.

Other fields, while related to the study of matter, have specific focuses that do not encompass the full spectrum of matter like chemistry does. Physics focuses on the laws of nature and the fundamental forces, while biochemistry specifically studies chemical processes within and related to living organisms. Organic chemistry, as a subset of chemistry, deals with the structure, properties, and reactions of organic compounds, but does not encompass all matter as broadly as chemistry does. Therefore, the correct answer accurately describes the discipline relevant to the question posed.
