Chemicals are present in almost everything. From what we eat to what we use to clean our home, they exist everywhere. A chemical is a form of matter that cannot be separated into different components or elements by physical methods but chemical methods are required to break the bonds in them. Each chemical have constant properties and they can be solid, liquid or gas. They are able to change between the phases of matter from solid to liquid to gas with changes in temperature or pressure. They can be mixed together to get new types of chemicals.
Chemicals are different from mixtures. Mixtures are different elements or compounds put together with no chemical bonds between them. Chemicals however are elements that are chemically bonded. Due to this, they are called pure and not mixtures. They can be a pure single element or compounds of elements.
Many of the products that we use are a result of chemical reactions. Chemicals are essential in the production of many different things, ranging from agricultural products, food and beverages to pharmaceuticals. In the recent times, there has been a huge rise in demand for them. To be able to supply chemicals, a supplier must first meet the standards set for the quality and production of chemicals within the country he or she practices in. Manufacturers are always on the lookout for good suppliers who can provide quality chemicals. Some policies that legislations can implement to ensure quality chemicals being produced are quality in packaging, labeling, production and distribution. Some companies who manufacture products including chemicals produce their own chemicals whereas some may seek them from suppliers. Chemicals can also be hazardous if not used with the correct procedures. Precautionary measures should be stated on packaging to ensure that consumers are aware of the hazards that they may pose if not used properly.
The reason why different people buy chemicals varies. Manufacturers of soap may buy sodium hydroxide to mix it with lard whereas a homeowner may buy hydrochloric acid for cleaning purposes and agricultural suppliers purchase raw chemicals to produce fertilizers and pesticides. Chemicals used in agriculture are called agrochemicals. They can be pesticides, fertilizers, mycotoxins and steroids.
Cosmetic products can also contain chemicals. Their intention can be to make a person look more attractive or presentable. Facial wash, shaving cream, lotions and skin creams are just some of the few cosmetic products that make use of chemicals.
Chemicals are present in almost any product that you can think of which difference lies whether they are in solid, liquid or gaseous state. With the developments in the science field, one can expect a variety of products and foods being developed over the next few years to improve the standards of living. The discovery of chemicals and their applications have truly benefited mankind in many ways.
