Modified sodium disilicate

, with molecular formula of Na2O•2SiO2 and commercial designation of

MDS

, is manufactured through special process of adding active auxiliaries   into

sodium silicate

. The pH value is within 10.5 – 12.5, Bulk density within 0.3—0.70g/ cm3. As a phosphorous-free detergent auxiliary, the

modified sodium disilicate (MDS)

satisfies all technical and ecological requirements for

substitute of STPP

.
