Cyclodextrin Inhibits Calcium Carbonate Crystallization and Scaling

beta-Cyclodextrin inhibits calcium carbonate crystallization and also reduces the degree of scaling on stainless steel surfaces. The rate of crystallization is not affected. The size of the calcium carbonate crystals is reduced by the cyclodextrin. Under the conditions used, the cydodextrin was effective at concentrations between 5 ppm and 100 ppm.
