The European Commission has requested ECHA to prepare a report on carcinogenic, mutagenic and reprotoxic substances (CMR) in childcare articles. This work will support the Commission in the preparation of a restriction proposal for CMR 1A or 1B substances in childcare articles on the basis of REACH Article 68(2). This call for evidence aims to collect information on suitable analytical methods to measure CMR 1A or 1B substances in childcare articles.
