The data base can be searched by name and synonyms, CAS- and EC number, or part of those. If you cannot find a certain chemical by searching via one option, try the other options. If a chemical appears to be absent, then it will be (for the time being) okay to use.

Acids, hydrides, chlorides, etc. are in the data base divided from the remainder of their name by a space. Therefore as an example "boric acid" will give you a hit, but "boricacid" will not. On the other hand "trialkylboranes" is one word. Thus if you are not certain about the spelling, please try several. The search should not contain any /, * or $ sign or any Greek symbol.

The Danish EPA (Environmental Protection Agency) data base contains to date (first quarter of 2011) the EC name, its Danish synonym, EC number, CAS number, classification(s) and structural formula of some 30,000 substances. These classifications have not been peer reviewed but are the result of QSAR (quantitative structure-activity relationship) calculations. The Danish EPA is an expert in this field and claims that the results of these calculations are 80% correct.

The Danish EPA uses abbreviations for the hazard classifications. Click relationships to find the relationship between these abbreviations, the full classification wording and the accompanying hazard statements.
