答案（中文）
根据 REACH 和 CLP，混合物是指“由两种或两种以上物质组成的混合物或溶液”。混合物可以通过混合两种或两种以上物质而不发生化学反应而获得。混合物中的物质应单独注册。多成分物质或 UVCB 物质是化学反应的产物。多成分物质或 UVCB 物质应按此方式注册。
Answer (EN)
Under REACH and CLP, a mixture is a “Mixture or solution composed of two or more substances”. It can be obtained by blending two or more substances without a chemical reaction. Substances within a mixture should be registered separately. A multi-constituent substance or a UVCB substance is the result of a chemical reaction. A multi-constituent substance or a UVCB substance should be registered as such.
