Chemical auxiliary zeolite 4a--STPP substitute 1.Stpp subsititute 2.Zeolite powder 3.Zeolite catalyst 4.Detergent raw material--zeolite 4a 5.Chemical auxiliary 6.Sodium zeolite

Have you ever thought of a kind of detergent auxiliary which is phosphorous-free but satisfies all technical and ecological requirements for substitute of STPP ? That is Modified sodium disilicate (MDS). It has got better solubility in water than 4A zeolite and stronger buffering effect comparing with STPP or 4A zeolite. Besides, MDS has got favorable water softening performance, good dispersion and suspending capacity, strong detergency ability, compatibility with bleacher. And it is nontoxic to people, animals and aquatic creatures, and comprehensively applicable to various detergents and different processing methods. Meanwhile, the performance of MDS is nearly the same as STPP and much better than 4A zeolite；it reduces the cost greatly (price is much lower than STPP), with good price-performance ratio. Have a try, and you will find it is the one that you have being looking for.
