The Research Institute for Fragrance Materials (RIFM) has concluded that P-Methyl Acetophenone is safe for use at currently declared levels. Human maximization tests have shown no skin sensitization reactions at concentrations up to 6%. While it is classified as a mild skin irritant, extensive evaluations covering genotoxicity, repeated dose toxicity, and other potential concerns indicate it is not genotoxic. It should be noted that acetophenone, a structurally similar compound, has been flagged by ECHA for potential reproductive toxicity; however, P-Methyl Acetophenone has not been directly assessed by the SCCS regarding this specific concern.
