Formulation
Stability
No specific optimal pH range for stability has been identified. Its synthesis at high temperatures (120-135°C) indicates inherent thermal stability. While exhibiting some water solubility (189.8 to 940.3 mg/L depending on isomer), it is predominantly oil-soluble with Log KOW values ranging from 2.68 to 3.49.
Safety
Safety Profile
Safety assessments, including those by the Research Institute for Fragrance Materials (RIFM) for closely related isomers, support its use within International Fragrance Association (IFRA) standards. This ingredient has been determined not to be genotoxic, phototoxic, or photoallergenic. Human repeat insult patch tests (HRIPTs) conducted at 2.5% in alcohol indicated a low sensitization potential, with a No Expected Sensitization Induction Level (NESIL) of 3000 μg/cm² for skin sensitization. For face/body products applied with fingertips, the maximum acceptable concentration is 0.57%.
