Benzodol Specification

Benzodol (CAS NO.54531-52-1) is also called (4-Hydroxyphenyl)arsonic acid polymer with formaldehyde ; Benzocal ; Polibenzarsol ; Polibenzarsol [INN-Spanish] ; Polybenzarsol ; Polybenzarsolum ; Polybenzarsolum [INN-Latin] ; A mixture of polymers formed by reacting formaldehyde with 4-hydroxybenzenearsonic acid ; Arsonic acid, (4-hydroxyphenyl)-, polymer with formaldehyde . Benzodol (CAS NO.54531-52-1) is high toxic. It is flammable. It will produce toxic arsenide fumes when buring. So the storage environment should be ventilate, low-temperature and dry. Keep Benzodol (CAS NO.54531-52-1) separate from raw materials of food.
