The company, Marion Biotech, bought the ingredient — propylene glycol (PG) — from trader Maya Chemtech India, as reported by Reuters. "Marion bought commercial-grade propylene glycol," said a second source, an investigator, who declined to be named while the inquiry is ongoing. International standards allow only trace amounts of EG and DEG in pharmaceutical-grade propylene glycol. The toxins were found in cough syrups exported to Gambia by the other Indian company, Maiden Pharmaceuticals. India made it mandatory for companies to have their cough syrups tested before export from June.
