aqueous foams

Aqueous foams are stable collections of tiny bubbles formed when a gas is dispersed in water, often with surfactants (soapy components) that reduce surface tension. These foams appear as frothy, light, bubbly substances, commonly seen in products like soaps, firefighting foam, or shaving creams. They behave like a foam mat with a network of interconnected bubbles. Aqueous foams are used for cleaning, fire suppression, and insulation, leveraging their ability to trap and displace gases or liquids effectively. Their properties depend on the water content, surfactant type, and bubble stability.
