Description

A semirigid colloidal dispersion that resembles JELL-O. A gel is a highly viscous solution of solid particles dispersed in a liquid. Gels may be form by cooling a solution to the point it forms tiny crystalline matrices that trap the solvent molecules. Gels are usually transparent, have low strengths and need external support. Examples of materials that form gels are: gelatin, jelly, starch, agar, pectin, polyacrylamides, and vinyl plastisols.
