| Applications | Uses: CIR ingredient: Disodium Phosphate, Used as emulsifier and buffer in foods and pharmaceuticals, metal phosphatising, electroplating reagent, scale inhibitor (boiling water treatment), textile, leather auxiliary, sequestrant, mordant in dyeing, fireproofing agent, reagent and buffer in analytical chemistry, cathartic, and veterinary laxative, Also used for weighting silk and in pottery glazes, porcelain, enamels, tanning, and soldering, brazing (instead of borax), [HSDB] Used in fertilizers, galvanoplastics, and as a dietary supplement, [Hawley], Brazing [Category: Heat or Machine], Electroplating [Category: Plate], Soldering [Category: Heat or Machine], Textiles (Fiber & Fabric Manufacturing) [Category: Industry], Leather Tanning and Processing [Category: Industry], Textiles (Printing, Dyeing, or Finishing) [Category: Industry], Ceramics making [Category: Hobbies], Enameling [Category: Hobbies], For Disodium phosphate (USEPA, OPP Pesticide Code: 076403) there are 0 labels match., SRP: Not registered for current use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses., The active ingredient is no longer contained in any registered pesticide products ... "cancelled.", Alone or combined with monosodium phosphate is used to make starch for instant puddings and pie fillings., Emulsifier (processed cheese, quick-cook cereals, pharmaceuticals), electroplating reagent), pottery glazes, leather auxiliary., For more Uses (Complete) data for DISODIUM HYDROGEN PHOSPHATE (9 total), please visit the HSDB record page., Use Classification: Food additives, Food Additives -> ACIDITY_REGULATOR, EMULSIFIER, TEXTURIZER, THICKENER -> JECFA Functional Classes, Cosmetics -> Buffering, Industry Uses: Other, Antioxidant, Solubility enhancer, Processing aids not otherwise specified, Not Known or Reasonably Ascertainable, Corrosion inhibitor, Soil amendments (fertilizers), Cleaning agent, Surface modifier, Adhesion, cohesion promoter, Processing aids, specific to petroleum production, Anti-scaling agent, Consumer Uses: Not Known or Reasonably Ascertainable, Laboratory chemicals, Household Products: Information on 238 consumer products that contain Disodium phosphate in the following categories is provided:, • Auto Products, • Commercial, Institutional, • Inside the Home, • Personal Care, • Pet Care, Methods of Manufacturing: By precipitating calcium carbonate from a solution of dicalcium phosphate with soda ash., By treating phosphoric acid with a slight excess of soda ash, boiling the solution to drive off carbon dioxide and cooling to permit the dodecahydrate to crystallize., ... The disodium, phosphate, is produced from phosphoric acid and sodium carbonate., Sodium monophosphates are usually produced by neutralization of phosphoric acid with soda ash or caustic soda. The latter is predominantly used in Germany, while in the United States, the less expensive soda ash prevails. The basicity of sodium carbonate is insufficient for the formation of trisodium phosphate, so that caustic soda must be used in this step. The phosphates crystallize from the solutions as hydrates and are separated by centrifugation. Anhydrous salts are obtained by dehydration in rotary dryers or directly from the solutions by spray drying or in rotary kilns. Both thermal phosphoric acid and the cheaper wet phosphoric acid are used as starting materials. The very pure thermal phosphoric acid is generally used in the production of food-grade phosphates., Sodium monophosphates, Both thermal and purified wet phosphoric acid are used in production. In a process developed in the 1980s, acidic phosphate solution (CaHPO4 in the presence of H3PO4) is treated with NaHSO4, whereby purification occurs through precipitation of gypsum. Neutralization with NaOH is carried out in a second stage. Salts are obtained from the neutralized solutions by evaporation, crystallization, and centrifugation. The desired hydrate is obtained by appropriate temperature control. The anhydrous product is also produced by dehydration of the solution in a spray drying tower. Careful temperature control is required to avoid formation of tetrasodium diphosphate., Formulations, Preparations: Sodium Phosphates Injection, USP, 3 mM P, mL (millimoles, mL)... Each mL contains 276 mg of monobasic sodium phosphate, monohydrate and 142 mg of dibasic sodium phosphate, anhydrous (equivalent to 268 mg of dibasic sodium phosphate, heptahydrate). ...
