9.8 Where can I find the composition of a proprietary chemical?
If it has been patented, the composition will be detailed in the patent,
and any local patent agent should be able to locate and obtain a copy.
Transportation regulations usually require manufacturers to list components,
consequently examination of the MSDS often provides an indication of major
components, some of which are likely to just be the solvent. There are also
compilations of chemical tradenames that may also indicate what the major
components in a proprietary chemical. Hawley, Gardner, Industrial
Chemical Thesaurus [43], Encyclopedia of Industrial Chemical Additives [44],
and the Chemical Tradenames Dictionary [45] are good starting points.
In some countries only the "active" or "toxic" ingredients have to be
disclosed, consequently chemical analysis would have to be undertaken.
Another technique is to look for equivalent formulations - to ascertain what
ingredients are typically used, and the multi-volume Chemical Formulary [46]
is one of the best sources if you can not justify a patent search.
