Search Engine Issues: The search in KnowSEC (upper right corner) is currently very slow, but accurate nonetheless. We are working on improving the search functionality in the future.

Welcome to KnowSEC#

This is a beta version of KnowSEC. KnowSEC is a web application aiming to manage Knowledge about Substances of Ecological Concern. In particular, we want to support decisions about the substances and also want to document these decisions and the work on the substances in general.

KnowSEC currently knows more thant 10000 substances, unknown substances can be added at any time.
You can search for substances in the search field in the top right (e.g. the CAS/EC number or the name).
When visiting a Substance Info Page you can enter new information about the substance with the Decisions Making dialog on the left or by writing a new memo.

Attention: KnowSEC currently support Mozilla Firefox and Google Chrome. Microsoft Internet Explorer is not supported at this point.
