The Swedish Chemicals Agency (KEMI) launched a consultation1 on medium-chain chlorinated paraffins (MCCPs). They are considering whether it is appropriate to restrict this substance under the EU RoHS Directive. The consultation aims to collect information and feedback about the study conducted by the KEMI and it runs until 15 September 2017.
MCCPs are highly toxic to aquatic life and hazardous to human. They are a group of chlorinated organic compounds that the carbon chain length ranges from 14 to 17 and they contain 40 – 63% chlorine content. MCCPs belong to the family of chlorinated paraffins, including short-chain (SCCPs) and long-chain (LCCPs). Some commercial available MCCPs may contain SCCPs. Currently, SCCPs are restricted under the EU Persistent Organic Pollutants (POPs) Regulation and listed in the REACH Candidate List. However, both MCCPs and LCCPs are not restricted under the EU REACH or POPs Regulation.
According to the KEMI’s study2, MCCPs are mainly used as a secondary plasticiser in PVC. This material is commonly used in cables and wires for sheathing and insulation. These are necessities in electrical and electronic devices. This implies these products may contain MCCPs. Moreover, MCCPs can be used as flame retardants in plastic, adhesive and sealants. As a result, the KEMI is considering to propose restriction under RoHS Directive. The suggested limit by the KEMI is 0.1% by weight per homogenous material.
