Assessing the safety of post-consumer recycled plastic (PCR) in contact with cosmetic products is difficult, because of the immense numbers of substances which may migrate from the plastic packaging into the cosmetic product. In this report, we provide the technical basis for developing criteria for two lists of hotspot substances, one for leave-on products and one for rinse-off products. We suggest that this can be used as an element in the quality documentation for the supply chain communication.
