説明Trisodium phosphate (TSP) is an inorganic salt used as industrial detergents, metal treatment and in toilet floor cleaners. TSP is pure cleaning power. Used as a water softener; for the treatment of boiler water; as a paint remover; in photographic developers; for tanning leather; for manufacturing paper; for clarifying sugar. Also, it is a common laboratory reagent. Use to dissolve dirt, grease, and mildew from siding, decks, masonry, boats, campers. To prepare surfaces before painting or staining wash with TSP. Trisodium phosphate is an approved food additive in the U.S., European Union and other countries of the world. It may be added to foods and beverages or smoothies and green drinks. The primary function of trisodium phosphate is acidity regulation. It is commonly present in dry, extruded cereals. Together with other phosphates, it modifies cereal color, aids the cereal's flow through the extruder and provides phosphorus fortification. It is also commonly present in cheese sauces as an emulsifier. Trisodium phosphate is a strong chemical and can cause severe eye damage and can burn unprotected skin. Poisoning occurs if you swallow, breathe in, or spill large amounts of this substance on your skin.

使用Trisodium phosphate (TSP) is a cleaning agent, lubricant, food additive, stain remover and degreaser. It is an alkaline cleaning agent that has been used as a household cleaner for many years, but ecological problems have largely ended that practice, at least in the western world. Substitutes are not as effective, but the raw chemical can be bought in bulk to add to other detergents. It works by disrupting the bacterial cell membrane and causing the contents to leak out, though the exact mechanism is not fully elucidated (Oyarzabal, 2005). Trisodium phosphate solutions are approved for treatment of beef carcasses in the US Code of Federal Regulations (21 CFR 182.1778; FDA 2003). By the end of the 20th century, many products that formerly contained TSP were manufactured with TSP substitutes, which consist mainly of sodium carbonate along with various admixtures of nonionic surfactants and a limited percentage of sodium phosphates. TSP is commonly used after cleaning with mineral spirits in order to remove hydrocarbon residues. TSP may be used with household chlorine bleach in the same solution without hazardous reactions. This mixture is particularly good for removing mildew, but is ineffective at permanently removing mold.
