Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

The Research Institute for Fragrance Materials (RIFM) has assessed p-α,α-trimethylbenzyl alcohol (CAS 1197-01-9), concluding it is not genotoxic and poses a low risk for skin sensitization at current usage levels. However, it is important to note that a related compound, p-Cymen-8-ol (alpha,alpha,4-trimethylbenzyl alcohol), has been associated with potential skin and eye irritation. No specific safety assessments by CIR, SCCS, or FDA were found for TRIMETHYLBENZYL ALCOHOL. The Cosmetic Safety and Technical Specification (2015 Edition, China) permits a maximum concentration of 1% for aromatic alcohols when used to inhibit pathogens.
