Description of key information

The ASA Category comprises 5 aromatic sulphonic acids and the appearance of those samples at 20 °C was:


TSA, Toluene-4-sulphonic acid (EC 203-180-0, CAS 104-15-4) - monohydrate crystal as tested. Hygroscopic when dried.


XSA, (Xylenes and 4-ethylbenzene) sulphonic acid (EC 701-247-3, CAS -) Former EC 246-839-8 - aqueous solution (ca. 65 %) as tested. Hygroscopic when dried.


CSA, p-cumene sulphonic acid (EC 240-210-1, CAS 16066-35-6) - aqueous solution (ca. 65 %) as tested. Hygroscopic when dried.


BSA, Benzene sulphonic acid (EC 202-638-7, CAS 98-11-3) - aqueous solution (ca. 65 %) as tested. Hygroscopic when dried.


HBSA, 4-hydroxybenzensulphonic acid (EC No. 202-691-6, CAS No. 98-67-9) - aqueous solution (ca. 65 %) as tested. Hygroscopic when dried.


The substances are deliquescent solid odourless at room temperature.
