About KATE2020

KATE2020 is an updated version of KATE2017 on NET.
For the main changes from "KATE2017 on NET", please see the Change Log.


KATE2020 uses the following software and libraries:


If you do not input a measured log P value of the chemical for which you want to predict the ecotoxicity, KATE2020 will use a log P value estimated by means of KOWWIN™ with permission by the U.S. Environmental Protection Agency.

* KOWWIN™ is owned by the U.S. Environmental Protection Agency and is protected by copyright throughout the world.


The prediction results generated by the KATE system are not guaranteed to be accurate. Please use this system as a reference tool for estimating the ecotoxicity values of chemical substances. Values predicted by KATE cannot be used to satisfy the requirement for ecotoxicity data that are necessary for notification regarding new chemical substances under the Japanese Act on the Evaluation of Chemical Substances and Regulation of Their Manufacture, etc. (Chemical Substances Control Law).
