👉 The Bennett fluid, also known as Bennett's fluid or Bennett's serum, is a colloidal suspension of colloidal particles in a liquid medium, typically water. Discovered by American chemist William Bennett in the early 20th century, it consists of a mixture of colloidal silica particles, which are stabilized by a surfactant known as C18-PEG-20. This fluid exhibits unique properties, including high viscosity and the ability to form stable emulsions and foams, making it useful in various industrial applications such as cosmetics, pharmaceuticals, and food processing. Its stability and ability to interact with biological systems have also made it a subject of interest in biomedical research.
