New phosphate-free detergent—Modified Sodium Di-silicate (MDS) Identification: Chemical name: Modified sodium disilicate Trade name: MDS CAS No.: 1344-09-8 Molecular formula: Na2O?2SiO2 MDS is manufactured from sodium silicate acting with active auxiliaries via special process. Its pH value range 10.5 – 12.5, Bulk density 0.3—0.70g/ cm3. As a phosphorous-free detergent auxiliary, MDS satisfies all technical and ecological requirements for substitute of STPP.MDS can be the best substitute of sodium tripolyphosphate(STPP) because of its comprehensively applicable to production of phosphorus-free washing powders under different conditions. Besides, the general performance is far superior to some related traditional products at the same price level, such as 4A zeolite.
