Description of key information

TSA is a solid substance and the viscosity was waived due to the physical state.

The viscosity of the other 4 aromatic sulphonic acids tested in liquid form ranged from 14 to 166 mm2/s at 50 °C.

XSA, (Xylenes and 4-ethylbenzene) sulphonic acid (EC 701-247-3, CAS -) Former EC 246-839-8: 166.2

CSA, p-cumene sulphonic acid (EC 240-210-1, CAS 16066-35-6): 100.1

BSA, Benzene sulphonic acid (EC 202-638-7, CAS 98-11-3): 13.91

HBSA, 4-hydroxybenzensulphonic acid (EC No. 202-691-6, CAS No. 98-67-9): 113.4
