Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
The most sensitive specie tested was alga with an EC50 value after 72 h of 18.6 mg/L and EC10 of 0.194 mg/L.
Additional information
Short-term toxicity to fish
The fish acute toxicity test of the test item Incozol 4 resulted in a LC50 of >101 mg/L.
Short-term toxicity to aquatic invertebrates
The acute immobilisation of Incozol 4 to the fresh water invertebrate Daphnia magna has been investigated. The 48-hour EC0 value was determined to be 15.5 mg/L. The EC50 value has been estimated to be >87.1 mg/L.
Toxicity to aquatic algae and cyanobacteria
A algae growth inhibition study was conducted according to the OECD guideline no. 201. The test item Incozol 4 inhibits the growth of 50 % of the algae at a concentration of ErC50 (0 - 72 h): 18.6 mg/L (95 % confidence limits: 16.0 – 21.6 mg/L). The no observed effect concentration, NOECr (0 - 72 h) was estimated to be 0.0259 mg/L. The EC10 was calculated to be 0.194 mg/L. Due to the big difference between EC50 and NOEC value, the classification and labelling and risk assessment is based on the more reliable EC10 value.
Toxicity to microorganisms
The study resulted in an EC50 of 3534 mg/L and in an EC10 of 894 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
