ACTIVATED CARBON (CAS 97793-37-8) — formula C72H26O7S, molecular weight 1035.0.
Documented applications: Uses: Used mainly in rubber (90%) and as a pigment (9%), [ACGIH] Carbon black is a manufactured material while soot is a waste product of combustion. Compared to soot, carbon black particles are more homogeneous and less biologically active.
