4A Zeolite detergent is the major builder of none phosphorus or low phosphorus detergent. This is 3 in 1 products confined Marjory with 4A Zeolite detergent, moderate sodium carbonate and organic polymer builder, has the same efficacy as sodium phosphate. It is not necessary to worry about the question of quality. 4A Zeolite detergent auxiliary can be confined with many surfactants. Such as linera alkybenzenesulfanate( LAS ), sulfactant-AE, a-olefin sulfonate, if configed with the last one, the efficacy would be especially better.
