Additional information

Experimental ecotoxicological results are only available concerning toxicity to aquatic microorganisms for 1-Propanesulfonic acid, 3-mercapto-, monosodium salt. All other available data were generated with the help of QSAR predictions with the scientifically accepted calculation program EPIWIN v4.1 (by US-EPA). The substance arises no toxicity concern for the environmental compartment.

Conclusion on classification

Regarding all available QSAR data for the environmental toxicity and taking into account the provisions laid down in Council Directive 67/548/EEC and CLP (EU GHS), the substance 1 -Propanesulfonic acid, 3 -mercapto-, monosodium salt does not have to be classified with respect to acute or chronic ecological toxicity.
