Abstract
A descalant means, comprising L.sub.E structured liquid crystals which when placed close to, or into a liquid stream, cause the formation of microscopic liquid crystalline structures, which act as nucleation sites for the formation of crystal structures of normally liquid-soluble or insoluble salts, and other suspended particles, these crystalline structures being chemically stable and causing a large reduction in the scaling potential of the liquid, thereby avoiding scale buildup on metal or other containment surfaces and also initiating descaling of surfaces already containing scale buildup. Furthermore, said means will reduce the amount of detergents, soaps, surfactants and polymers required in washing and other forms of water use.
