Summary

Formulations and their uses

In a nutshell

Formulations are made up of several different compounds and/or elements which are used in specific quantities. The type of chemicals can be changed and the quantities can be altered to make the formulation more suitable for a different function.



Formulations 

A pure substance is one which contains only one type of compound or element. 


Formulations are mixtures which contain specific amounts of several compounds and/or elements. The type of substances used and the quantities they are used in determine the properties of the formulation and therefore its function.

​

Formulations are created for a specific purpose and each formulation is made using a different recipe.



Useful formulations 

​​Formulations are found in products used in everyday life such as fuels, cosmetics, perfume, processed foods and fertilisers.​


Example

Explanation 

Medical pills
  • Medical pills are made up of drugs, binders and preservatives. 
  • The formulation of pills are carefully selected to ensure that the drugs are delivered to the target in the correct concentration, the pills have a sufficient shelf life and can be easily consumed.
Paint
  • Paint is made up of several components: pigment, solvent, binder and additives. 
  • The quantity and type of chemicals can be altered to give a different colour or thickness, therefore making the paint suitable for a different purpose. 
Perfume
  • ​Perfume is made up of fragrances, which give the perfume its characteristic smell, and solvent which prevents different layers of liquid from forming.
Processed food
  • Processed food is made up of ingredients which give the desired flavour, texture and preservatives which ensure that the shelf life is suitable.
