Formulations

This lesson covers formulations as a specific type of mixture, as required by the AQA GCSE Chemistry specification (8.1.1). A formulation is a mixture designed for a particular purpose, where each component is present in a carefully measured quantity. Understanding formulations is important because they are used extensively in industry — from medicines and paints to cleaning products and fuels. You need to be able to identify formulations and explain why each component is included.

What Is a Formulation?

A formulation is a mixture that has been designed as a useful product. Each component in a formulation is present in a measured quantity and contributes to the desired properties of the product.

Unlike a random mixture, a formulation has a precise composition that has been carefully developed and tested. Changing the proportions of the components would change the properties of the product.
