Description of key information
The ASA Category comprises the following 5 aromatic sulphonic acids:
TSA, Toluene-4-sulphonic acid (EC 203-180-0, CAS 104-15-4)
XSA, (Xylenes and 4-ethylbenzene) sulphonic acid (EC 701-247-3, CAS -) Former EC 246-839-8
CSA, p-cumene sulphonic acid (EC 240-210-1, CAS 16066-35-6)
BSA, Benzene sulphonic acid (EC 202-638-7, CAS 98-11-3)
HBSA, 4-hydroxybenzensulphonic acid (EC No. 202-691-6, CAS No. 98-67-9)
Aromatic sulphonic acids are non-flammable as determined for 5 of the acids, including liquid and solid forms as per available tests' results.
EU Method A10, flammable solids for TSA
EU Method A12, (Flammability (Contact with Water)) for all the substances (TSA, BSA, HBSA, XSA and CSA)
EU Method A13 Pyrophoric Properties of Solids and Liquids) for all the substances (TSA, BSA, HBSA, XSA and CSA).
No flammability or reaction with water or ignition in contact with air were observed.
Key value for chemical safety assessment
- Flammability:
- non flammable
