毒理性
鉴定和使用:三钠三聚磷酸盐以无色的三方斜方棱镜状晶体存在。它用于牙齿抛光剂和在合成乳制品中使用。它用于洗涤剂加工、水软化剂、螯合剂、乳化剂、食品添加剂、纺织品加工和洗涤。人类接触和毒性:由于过量的碱性而不是钠含量过多,诸如亚磷酸盐的disodium盐具有毒性。动物研究:喂食含有这种化学物质的高剂量的饮食的大鼠对肾脏产生了不良影响。在大鼠喂食含有这种化学物质的饮食中也观察到生长迟缓。
IDENTIFICATION AND USE: Trisodium trimetaphosphate exists as colorless efflorescent triclinic rhombohedral prisms. It is used in tooth polishing agents and used in synthetic dairy products. It is used in detergent processing, water softeners, sequesterants, emulsifiers, food additives, textile processing, and laundering. HUMAN EXPOSURE AND TOXICITY: Disodium salts such as the metaphosphates are toxic because of their excess alkalinity rather than from sodium excess. ANIMAL STUDIES: Rats fed diets containing this chemical, high doses had adverse effects on kidneys. Growth retardation was also observed in rats fed this chemical in diets.
