Is Poly(styrenesulfonate) sodium salt Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Poly(styrenesulfonate) sodium salt? Is Poly(styrenesulfonate) sodium salt safe for nursing mother and child? Does Poly(styrenesulfonate) sodium salt extracts into breast milk? Does Poly(styrenesulfonate) sodium salt has any long term or short term side effects on infants? Can Poly(styrenesulfonate) sodium salt influence milk supply or can Poly(styrenesulfonate) sodium salt decrease milk supply in lactating mothers?

Because Poly(styrenesulfonate) sodium salt is not orally absorbed, it is unlikely to reach the breastmilk or adversely affect the breastfed infant after maternal administration. No special precautions are required. A suspension of Poly(styrenesulfonate) sodium salt has been added directly to breastmilk to lower the potassium concentration of milk for use in infants with renal impairment. In addition to lowering average potassium content by 65%, the calcium content of breastmilk was reduced by 84%.[1] Infants given either expressed breastmilk, formula or a combination of both had their average serum potassium levels decreased by 24% from 6.3 to 4.8 mEq/L. Serum calcium and creatinine also decreased slightly. The infants had no clinically noticeable side effects.[2] Addition of large amounts of Poly(styrenesulfonate) sodium salt to artificial formula also lowers the calcium, copper, manganese, phosphorus, sulfur and zinc concentrations; whereas the iron, sodium and sulfur content of formulas are increased.[3] Similar changes might occur with breastmilk.
