In law, "chemical substances" may well consist of both equally pure substances and mixtures with an outlined composition or production system. As an example, the EU regulation Arrive at defines "monoconstituent substances", "multiconstituent substances" and "substances of unknown or variable composition". The latter two consist of a number of chemical substances; however, their identification could be set up possibly by direct chemical analysis or reference to one producing method.
