Mixture

Under REACH Article 3(2), a mixture is a mixture or solution composed of two or more substances. Mixtures as such are not registered under REACH, but the substances they contain must be registered. Suppliers of mixtures must provide Safety Data Sheets to professional recipients for classified mixtures, and must communicate SVHC content above 0.1% w/w to recipients and consumers. The REACH SDS obligations (Articles 31–32) apply throughout the mixture supply chain.

REACH Regulation (EC) No 1907/2006, Article 3(2); Articles 31–32.

Formulators and distributors of mixtures must: verify that all constituent substances are registered; provide SDS to professional recipients for classified mixtures; communicate SVHCs above 0.1% in the mixture; and ensure exposure scenarios from suppliers’ eSDS cover the formulation use. Where mixtures are used to produce articles, the downstream article producer must assess SVHC content in the article per the 0.1% w/w article-level threshold.
