Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 5000 lb or 2270 kg. The toll free number of the NRC is (800) 424-8802; In the Washington D.C. metropolitan area (202) 426-2675. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b).

IDENTIFICATION AND USE: Pentasodium tripolyphosphate is a white powder which is soluble in water.r It is used as a hydrogen peroxide stabilizer. This chemical is one of the most widely used and most effective builder in heavy duty fabric washing compositions. Because of its high sequestration power, it also finds extensive application in automatic dish washing detergents. It forms stable hydrates and aids in the manufacture of crisp spray dried laundry powders. It is used in dairy substitute products: milk based pudding, whipped topping, sour cream, and cheese. It is used in water softening and as a peptizing agent; emulsifier and dispersing agent, it is an ingredient of cleansers in drilling fluids to control mud viscosity in oil fields; as preservative, sequestrant, and as a texturizer in foods. The active ingredient is no longer contained in any registered pesticide products used in the United States. HUMAN EXPOSURE AND TOXICITY: If ingested in large amounts this chemical can cause nausea, vomiting, and diarrhea. It has produced vesiculation when applied to intact and abraded skin of humans. Sodium and potassium hexametaphosphates, polyphosphates, tripolyphosphates, pyrophosphates, and other phosphates used as water softeners form complexes with calcium and, after ingestion, are capable of seriously reducing the serum level of ionic calcium. They have less corrosive effect on mucous membranes than sodium or potassium hydroxide. Eye contact with concentrated material can cause conjunctival edema and corneal destruction. Chronic dermatitis may follow repeated contact of the chemical that migrates to food from packaging materials. Occupational exposure involves acetyl cellulose makers, bronze alloy makers, munitions workers, smoke bomb and incendiary makers, pesticide rat poison worker, fertilizer makers, electroluminescent-coating makers, and semiconductor workers. ANIMAL STUDIES: This chemical induced emesis in dogs. Dietary administration in animals has caused decrease iron content in bone, liver, and spleen, and bone depletion of calcium.

The mechanism by which sodium tripolyphosphate increases cadmium toxicity after sc administration was investigated in mice after a dose of cadmium (30 umol/kg), alone or with sodium tripolyphosphate (90 umol/kg). ... Histological ... changes in the liver were not observed during the first 12 hr after injection of cadmium, but already 6-8 hr after injection of cadmium plus sodium tripolyphosphate early centrilobular necroses and blood stasis appeared. At 12 hr more advanced necroses were present. Sodium tripolyphosphate administered alone was nontoxic and did not change the liver morphology, when compared to animals killed immediately after injection. During the first 12 hr after cadmium administration with sodium tripolyphosphate, there was a much faster transport of cadmium, giving rise to higher liver and kidney concn of cadmium and partial inhibition of cadmium-metallothionein binding, as compared with animals receiving the same dose of cadmium without sodium tripolyphosphate.|The adjuvant effect of di-sodium DL-alpha-glycerophosphate on the rectal absorption of cefoxitin (as the sodium salt) was greatly augmented by the presence of ... sodium tripolyphosphate. ...

If ingested in large amounts nausea, vomiting and diarrhea are probable. Thought to be hydrolyzed to (ortho)phosphates before absorption. If appreciable amounts of the intact polymer are absorbed from the alimentary tract, hypocalcemic tetany may be a danger due to the binding (chelation) of ionized calcium. Hypocalcemic tetany apparently occurred in one ingestion episode. /Tripolyphosphate/

The effects of condensed phosphate ( ... sodium tripolyphosphate ... ) on the growth of Streptococcus mutans, sugar metabolism in vitro, and S mutans-induced caries of hamsters were studied. All condensed phosphates depressed the growth of S mutans. This growth inhibition was reversed by divalent metal ions. Thus, the chelating capacity of condensed phosphate is responsible for their antibacterial actions. Condensed phosphates depressed lactate production from glucose and sucrose by the S mutans.
