Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
The multiconstituent substance is a reaction mass of inorganic an organic acids. The substance itself constains considerable amounts of water (46.2%) that cannot be removed without changing the identity of the substance itself. The constituent sulfuric acid has a strong affinity to water. Therefore it is very difficult to concentrate sulfuric acid. The system water/sulfuric acid are an azeotrope. If heating of the substance is enhanced to remove more water, it is to be expected that H2SO4 will be lost from the substance. Therefore it is not possible to reduce the water content to 20% without changing the composition. Furthermore we cannot exclude any decomposition reactions of the benzene sulfonic acids by high heat.
The substance is imported as aqueous solution. Since the substance is used in all cases as aqueous solution as imported, it was decided to use the aqueous solution for the tests necessary für the information requirements according to the tonnage band 1 - 10 t/a standard requirements (REACH Regulation) for the endpoints "24h- and 48hEC50i against Daphnia Magna Annex VII; 9.1.1", "72h Algal Inhibition Test Annex VII; 9.1.2".
The first reason for this procedure is that the substance is only used as aqueous solution, so that the situation of the use of the substance is realistic for the environment and the worker. The second reason is that it makes no sense to concentrate the aqueous solution of the substance prior the above mentioned tests in order to dissolve it again in water to perform the tests.
In a test under static conditions according to OECD Guideline 202 the 48 – hour EC50 is > 100 mg /L (nominal based on test item), corresponding to >27.7 mg/L (active ingredients)
The 48 – hr NOEC based on (mortality/immobilization) is ≥ 100 mg/L (nominal based on test item), corresponding to ≥ 27,7 mg/L (active ingredients).
The test item is not toxic angainst Daphnia magna.
In a 72 hour toxicity study according to the OECD Guideline 201, toxicity against Desmodesmus subspicatus ErC50 and EyC50 is > 100 mg/L , corresponding to >27.7 mg/L (active ingredients) as well as ErC10 and EyC10.The 72h NOEC based on growth rate as well as yield is ≥ 100 mg/L, corresponding to ≥27.7 mg/L (active ingredients) .
No inhibition of algal growth was observed.
