Chemical: Diphosphoric acid, disodium salt

Regulation (EC) No 1935/2004 (amended)

Diphosphoric acid, sodium salt (1:2) is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Diphosphoric acid, sodium salt (1:2) are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)

REACH registered substance: Disodium dihydrogenpyrophosphate (EC: 231-835-0)

Diphosphoric acid, disodium salt: Does not have an individual approval but may be used under an appropriate group standard

A skin, eye, and mucous membrane irritant; [SAX] Generally regarded as safe (GRAS) for use in foods; Ingestion of high doses may cause GI irritation; Absorption of sufficient phosphate can induce hyperphosphatemia, hypocalcemia, and/or hypomagnesemia and lead to cardiac arrest; Oral LD50 (mouse) = 2650 mg/kg; Intravenous LD50 (mouse) = 59 mg/kg; [HSDB] An eye and respiratory tract irritant; [MSDSonline]

Sodium acid pyrophosphate used as a general purpose food additive in animal drugs, feeds, and related products is generally recognized as safe when used in accordance with good manufacturing or feeding practice.

Sodium acid pyrophosphate used as a multiple purpose GRAS food substance in food for human consumption is generally recognized as safe when used in accordance with good manufacturing practice.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
