Of key importance, as noted earlier, plaque is likely to be a zone relatively free of crystal growth inhibitors. This is because of the presence of numerous enzymes able to break down both salivary pyrophosphate and salivary proteins. Watanabe et al. [123] observed a significant correlation between supra-gingival calculus scores and protein activity in saliva. They demonstrated that the protease originated in plaque bacteria [124, 125] and that the enzyme was able to nullify the inhibiting effect of salivary protein on calcium phosphate precipitation in vitro [125],... 

The use of crystal growth inhibitors for example, flat dye molecules which are insoluble in the oil are strongly adsorbed onto the particle surface, and this prevents particle entry into the oil droplets. 

Assume a solution supersaturated with one crystallizable solute. To part of the solution, a crystal growth inhibitor is added. It is established that in both cases the relation Lc = a(ln fi)2 holds, only the constant a being different. Assume now that both solutions have the same initial, rather weak, supersaturation and that crystallization is started by adding tiny seed crystals. Would the ratio of the overall crystallization rates d(p/dt now be the same as the ratio of both a values ...

Bicarbonate (HC03 ) results from the chemical decomposition of dissolved CO2 with the hydroxide ion in water. A portion of the bicarbonate present in the feed water can be converted to carbonate as a result of pH changes owing to concentration of salts on the concentrate side of the membrane. Such cases require the addition of acid or a crystal growth inhibitor to avoid calcium carbonate scaling. 

Calcium (Ca ) forms insoluble or sHghtly soluble salts with common ions such as carbonate and sulphate. Both can be adequately controlled through crystal growth inhibitors or, if the precipitate is allowed to form, can readily be removed by cleaning the RO membrane. Calcium concentration, in conjunction with alkalinity and sulphate concentration, often establishes the upper Hmit to the water recovery of the RO system. 

Strontium (Sr ) is found in less than 20% of water supplies. It forms a salt with sulphate ion that is soluble up to 1 ppm in concentration. It is kept in suspension with a crystal growth inhibitor. 

While much of the literature descriptions of the crystal structures of various carbamazepine forms have focused on differences in hydrogen bonding, it is possible that saccharin disrupts the tt-stacking observed in the anhydrous forms and the dihydrate inhibiting the precipitation of those forms from solution. In this case the co-crystal former, saccharin, may also act as a very effective crystal growth inhibitor for certain, less...

Many surfactants and polymers may act as crystal growth inhibitors if they adsorb strongly on the crystal faces, thus preventing solute deposition. However, the choice of an inhibitor is still an art and there are not many rules that can be used to select crystal growth inhibitors.
