Synthetic detergent grade zeolites, are the principle alternative to phosphate type builders, used in household detergents and softening the washing water by calcium ion exchange. The major part of phosphate-free household detergents is based on the use of Zeolite as builder. As a detergent builder, Zeolite type A was developed specifically as an environmentally preferable alternative to phosphate builders, which can cause eutrophication of freshwater bodies by nourishing excessive amounts of algae.
Zeolites possess a number of advantages over other builders during the production of detergents. With regards, zeolites display a very high product stability, regardless of the particular process employed (spray drying, granulation, extrusion etc). They prove inert when exposed to elevated temperatures, mechanical influences or alkalinity.
The high flexibility of zeolite with respect to formulation and ease of processing together with the economic advantage of the raw material have led to it becoming an extremely attractive builder.
