Why particles of toothpaste act like a liquid?

Particles of toothpaste behave like a liquid due to their unique formulation and the presence of both solid and liquid components. The solid particles, often made of abrasives and thickeners, are suspended in a gel or liquid base, allowing them to flow and spread easily when pressure is applied. This combination gives toothpaste its viscous, non-Newtonian properties, enabling it to adapt to the forces exerted during brushing while maintaining its ability to hold shape when at rest.
