In every profession or field, there is always a phase of research and learning. For the chemical industry, understanding the issues deeply is even more crucial. This is because chemicals are special, specific products that can cause unpredictable dangers. They negatively affect not only the health and lives of users but also those around them. Understanding the importance of knowing chemicals, Cường Thịnh Chemical Company has compiled information about what chemicals are and related concepts. Let’s explore the details in the article below!
What are chemicals?
There are many different definitions of chemicals. There are many different definitions of chemicals. According to the "Chemical Terminology Simplified," a chemical is "a form of matter with constant chemical composition and properties." These cannot be separated into smaller components by physical methods and require breaking chemical bonds. Chemicals exist in the form of gas, liquid, solid, or plasma. Their state can change under the influence of temperature and pressure. Energy forms such as light and heat are not considered chemicals.
The definition of chemicals by OSHA is "any substance or mixture of substances," which is quite broad. It is also considered that the term "chemical" is an adjective meaning related to chemistry or chemical issues. Chemistry is the study of matter and its transformations.
In Clause 2, Article 3 of Circular 04/2012/TT-BCT, it states: "Chemicals are elements, compounds, or mixtures of substances that humans extract or create from natural or synthetic raw materials."
In short, chemicals can be understood as a substance produced or used in chemical reactions that involve changes to atoms and molecules. They can exist in liquid, solid, gas, or plasma states and can change depending on external factors.

Some related concepts about chemicals
Chemicals play an important role in life:
-
Substance: A substance is an element, compound, or even impurities produced in the processing process, as well as necessary additives to ensure physical-chemical stability. They do not include solvents, and when separated, the properties of that substance do not change.
-
Mixture: A mixture consists of two or more substances that do not undergo a chemical reaction under normal conditions.
-
Hazardous chemicals: These are substances with one or more hazardous properties.
-
Pure chemicals: Pure chemicals differ from various mixtures. Common products in this form are diamond (carbon), gold, table salt (sodium chloride), and refined sugar (sucrose). However, in practice, pure chemicals are rarely encountered because they usually exist in the form of mixtures. For example, water from filtration plants contains a small amount of dissolved sodium chloride and compounds containing iron and calcium.
-
Synthetic chemicals: Synthetic mixtures originated about 5,000 years ago. In ancient times, humans began combining metals (such as copper and tin) to create a strong, malleable metal known as bronze. The emergence of bronze marked the beginning of a new era as it was used to create tools, weapons, and armor.
Over time, copper material became outdated, and many other types of synthetic mixtures were created. For instance, combining different materials created stainless steel, lightweight aluminum, and other useful products.
Synthetic chemicals have contributed to the development of the food and pharmaceutical industries. They are used to preserve the flavor of food at low cost and to create various textures, from brittle to smooth. In the pharmaceutical industry, humans combine different chemicals in medicines to treat various disorders.
