The existing information was reviewed by the independent Expert Panel for Fragrance Safety and supports the use of 4-isopropylphenol as described in this fragrance ingredient safety assessment. The data for a read-across compound, p-cresol (CAS # 106-44-5), indicate that 4-isopropylphenol is not expected to be genotoxic. The calculated Margin of Exposure (MOE) for repeated dose and reproductive toxicity is greater than 100, based on data for p-cresol. Data for another read-across compound, thymol (CAS # 89-83-8), show no safety concerns for skin sensitization at current usage levels as a fragrance ingredient. An evaluation based on ultraviolet/visible (UV/Vis) spectra indicates that 4-isopropylphenol is not likely to cause photoirritation or photoallergenicity. The local respiratory toxicity was assessed using the Threshold of Toxicological Concern (TTC) for a Cramer Class I material, and the exposure to 4-isopropylphenol is below the TTC (1.4 mg/day).
Dermatotoxin - Skin burns.
Toxic Pneumonitis - Inflammation of the lungs induced by inhalation of metal fumes or toxic gases and vapors.
The existing information was reviewed by the independent Expert Panel for Fragrance Safety and supports the use of 4-isopropylphenol as described in this fragrance ingredient safety assessment. It was found not to be Persistent, Bioaccumulative, and Toxic (PBT) according to the International Fragrance Association (IFRA) Environmental Standards. Its risk quotients, calculated based on its current volume of use (VoU) in Europe and North America (i.e., Predicted Environmental Concentration/Predicted No Effect Concentration [PEC/PNEC]), are less than 1.
