Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Abiotic degradation

Based on the chemical structure toluene sulfonic acid can be predicted to be stable to hydrolysis. Similarly, based on the UV absorption spectra, no absorption occurs above 290 nm and thus the substance will be stable to photolysis.

Biotic Degradation

AS305BDis stable to hydrolysis however it will be rapidly biodegraded mainly by mineralisation to CO2 in natural systems. Up to 79% was mineralised after 28 days in the ready biodegradability (CO2 Evolution Test) study. The substance is therefore classified as readily biodegradable in natural aquatic systems at expected environmental concentrations.

The calcium salt of toluene sulfonic acid is considered to be representative of toluene sulfonic acid as the salt rapidly dissociates into the appropriate ions and is suitable for read-across as a structural analogue.
