1. What are aerosols?
Introduction i
Aerosol products
There are many aerosol products - each with its own properties.
Aerosol sprays
Aerosols have many uses; the most common are deodorants and body sprays. However, many products come in aerosols. Here are some other examples:
  • asthma sprays
  • insecticides
  • shaving foam
  • hair spray
  • cleaning sprays
  • oven cleaner.

Even though they are all aerosols, each spray has its own properties. For example, shaving foam is very different from a body spray - even though they are both aerosols. How do we make them different?

In this electronic resource (e-source) we will see how scientists make each aerosol perform in the way they want.

Always follow the instructions on the can and pay attention to safety advice and warnings.
