Safety
Safety Profile
No specific CIR or SCCS safety review has been conducted for Hydratropic Alcohol (2-Phenylpropan-1-ol). However, human experience with a 6% solution has shown no irritation or sensitization. It is crucial to distinguish it from its isomer, 2-Phenyl-2-propanol, which has been linked to potential allergic reactions. The FDA has recognized 2-Phenylpropan-1-ol as a synthetic flavoring substance for food use.
