Description:
MDS is a modified sodium silicate auxiliary. Based on the raw material sodium silicate it is manufactured through special process by adding active organic polymer materials. Its pH is between 10.0 and 12.5, bulk density between 0.2/cm3 and 0.9/cm3 and solubility over 80g/100g in water. It resolves fast in water and requires lower resolving temperature. It has much better solubility than sodium tripolyphosphate (STPP) and any other sodium silicate products in powder. As a cleaning auxiliary free of phosphate MDS can meet requirements for a substitute of STPP, both technically and ecologically.
Characteristics:
MDS has got very good binding and exchange capacity with calcium ion and magnesium ion, therefore performs very well in water softening. What is else, it requires lower washing temperature.
It has got very good solubility in water.
It has very good pH buffering effect. Comparing with STPP or 4A zeolite MDS has stronger buffering effect and thus better maintains the alkalinity for second time washing.
It is available to various detergents and suitable to all kinds of detergent processes. It can be used either as an ingredient for washing powders by tower process or as an ingredient for concentrated washing powder. It also serves as a basic raw material for paste and liquid detergents.
It has stronger oil removing ability. MDS has higher active alkalinity and therefore it can remove oil dirt independently. Its oil absorption capability comes up to 70%. With no existence of any other kinds of surfactants and/or cleaning auxiliaries, the oil removing capacity of its 5% water solution reaches 70%. This is un-comparable by any other cleaning auxiliaries including STPP.
It has very good synergistic effect with surfactants. MDS synergies very well with anionic surfactants and cationic surfactants.
It has very good emulsifying effect on oil dirt deposits. MDS can decompose, suspend and disperse dirt particles and minimize their deposition on fabrics. It is not corrosive and does no damage to fabrics.
It has proper bulk density. Its bulk density is between 0.2 -0.9/cm3.
It has very good compatibility with other functional aids such as bleaching agents.
It is an ecologically friendly product. It has no toxicity to human being, animals and aquatic creatures. It causes no eutrophication problem and brings no pollution to environment when getting into soils, rivers and oceans.
