Dispersion systems are mixtures where small particles are distributed throughout a continuous medium, such as a liquid or gas. These systems can be classified into two main types: suspensions, where solid particles are dispersed in a liquid, and aerosols, where tiny liquid droplets or solid particles are suspended in a gas. The stability of dispersion systems is crucial for their effectiveness in various applications, including pharmaceuticals, cosmetics, and food products. Factors like particle size, concentration, and the properties of the dispersing medium can influence how well the particles remain evenly distributed over time.
