Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The two data on Artemia larvae with THPC are considered as not reliable as documentation is unsufficient for assessment.

Because of the salt nature of THPC, hazard properties of chloride salt could be predicted to be equivalent to hazard properties of the sulphate salt (THPS). That is why a study performed with THPS is reported in this section, it is a study on A. tonsa, as it is considered as the most sensitive species for THPS.

The acute toxicity of THPS was tested on A. tonsa, according to the ISO standard14669. The 48h-LC50is 0.46mg/L (nominal, as anhydrous active substance). Therefore, THPS is very toxic to seawater invertebrates.

By analogy with THPS, THPC has to be considered as very toxic to aquatic invertebrates.
