General features
Sodium trimetaphosphate is an inorganic salt, the sodium salt of triphosphoric acid.
Sodium trimetaphosphate can be found in a dehydrated state or in a complex with 6 water molecules. The pH value is above 10. When it accumulates in water, it causes eutrophication. This reduces the amount of oxygen in stagnant waters and threatens the life of living things. Although it is very suitable for use in detergents, it is not preferred due to this feature.
production
Sodium trimetaphosphate;
Sodium trimetaphosphate is produced by the reaction of disodium phosphate and monosodium phosphate in stoichiometric ratios and under sensitive conditions. In this way, approximately 2 million tons are produced annually.
Usage areas
Sodium trimetaphosphate is used as a 'filler' in detergents with its trade name.
Sodium trimetaphosphate is a very good ion scavenger to remove Mg+2 and Ca+2 ions in hard water. However, since it is a good oxidizer, it is very successful in removing dirt. It is used in many different cleaning agents, from dishwashing detergents to laundry detergents, toothpaste to dishwasher tablets, as it is very good at preventing the hydrolysis of oil and the sedimentation of dirt.
At the same time, Sodium trimetaphosphate is a frequently used food additive as a humectant emulsifier.
