Expert Verdict

DMP carries a generous margin of safety of 13,500 per SCCP 2007 and is not restricted under EU Regulation 1223/2009 or by the FDA. However, its primary occurrence in cosmetics is as an unintentional contaminant from plastic packaging, and the broader industry trend toward phthalate-free formulations makes proactive elimination the preferred compliance position.
