Classifications by law
Annex VI of the CLP regulation (formerly Annex I of Directive 67/548/EEC) lists nearly 4 000 substances with their binding classification and labelling. This often contains concentration rows which are to be applied instead of the concentration table percentages for mixture classification. Since CLP was put in force, M factors for classification limits in environmental hazards add to this. Without this data, no software can calculate correct classifications.
On the other hand, many of the listed substances do not exist in the market (anymore) and the list does not cover many very common chemicals. We can add substances to deliver a database for your software which really helps in everyday work.
