Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Aluminium sulphate is inorganic substance and according “ANNEX VII - STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF ONE TONNE OR MORE” the study does not need to be conducted if the substance is inorganic.
The estimated Partition coefficient n-octanol/water of -5.08 log Kow at 20 °C was measured by calculation from EPI SuiteTM v4.0 Program.This is Exposure Assessment Tools and Models made from EPA (Environmental Protection Agency).
Data interpretation : Log Kow = -5.08 = Low bioacucmulation
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -5.08
- at the temperature of:
- 20 °C
Additional information
Partition coefficient n-octanol/water
Aluminium sulphate is inorganic substance and according “ANNEX VII - STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF ONE TONNE OR MORE ”the study does not need to be conducted if the substance is inorganic.
The study does not need to be conducted if the substance is inorganic.
If the test cannot be performed (e.g. the substance decomposes, has a high surface activity, reacts violently during the performance of the test or does not dissolve in water or in octanol, or it is not possible to obtain a sufficiently pure substance), a calculated value for log P as well as details of the calculation method shall be provided.The estimated Partition coefficient n-octanol/water of -5.08 log Kow at 20 °C was measured by calculation from EPI SuiteTM v4.0 Program.This is Exposure Assessment Tools and Models made from EPA (Environmental Protection Agency).
