摘要:
Provided is a powder containing ferric pyrophosphate that affords high iron absorbability, as a main component of an oral iron preparation. The present invention relates to a composite powder containing ferric pyrophosphate, which is a powder containing ferric pyrophosphate and a sodium component, wherein (1) the content of ferric pyrophosphate is 95 wt% or higher, and (2) a (Fe+Na)/P molar ratio is 0.8 to 1.0.
摘要:
A sanitary finished stuffed/plush toy and the manufacturing method thereof, which provides sanitary condition for play by the infants and children, wherein the fabric materials are treated and affixed with an antibacterial chemical which is colorless, transparent and unharmful to the human body, and the raw material particles of the plastic projections which are used for an eye, nose, etc. of the stuffed/plush toy are treated with the antibacterial chemical, in order to maintain the semi-permanent antibacterial activity in whole even after washing.
摘要:
A composition consisting essentially of ammonium pyrophosphate and having at least 70% of its phosphorus content present in the form of pyrophosphate is useful as a flame retardant for various materials.
摘要:
A concentrated aqueous alkali metal polyphosphate solution is prepared by adding polyphosphoric acid having a P₂O₅ assay of about 82% to about 85% to a quantity of concentrated aqueous alkali metal hydroxide sufficient to neutralize the acid. The resulting polyphosphate solution is richer in pyrophosphate and tripolyphosphate moieties than the acid.
摘要:
Novel processes are provided for producing anhydrous dicalcium phosphate (DCPA) and the gamma and beta forms of calcium pyrophosphate (CPP) from the reaction of phosphoric acid and lime. Dentifrice compositions containing the resultant phosphates are also disclosed.
