Creeping: an efficient way to determine the anticaking ability of additives for sodium chloride

This article investigates the relationship between additive induced creeping and anticaking activity in sodium chloride. Through a series of creeping experiments and powder flow analysis, we establish a clear correlation between the amount of creeping and the anticaking effect of an additive. Habit modification is found not to be a sufficient condition for an anticaking agent. The correlation is explained by the fact that both creeping and anticaking require blocking of crystal growth.
