Stability
For optimal integrity, this chemical should be stored in sealed containers under dry, room temperature conditions. While no specific optimal pH range for stability in skincare formulations was found for this compound, a related substance, p-t-Butylphenol, demonstrated stability at pH 4, 7, and 9 at 25 °C.

Safety
Safety Profile
P-TERT-BUTYLPHENYL ACETONITRILE is listed as 'ACTIVE' by the FDA Global Substance Registration System (GSRS) and EPA TSCA. A safety assessment by the Research Institute for Fragrance Materials (RIFM) concluded that existing information supports its use as a fragrance material and does not present a safety concern for skin sensitization under current declared levels of use. However, Material Safety Data Sheets (MSDS) classify the pure form as a hazardous chemical by OSHA standards, citing potential for serious eye irritation, respiratory irritation, and harm upon contact with skin or if swallowed. GHS classification reports predominantly indicate 'Not Classified' (99.9%) for hazard criteria, though a small fraction of companies (0.1%) provided hazard statements related to eye, respiratory, and skin irritation, and harm if swallowed.

Verdict
P-TERT-BUTYLPHENYL ACETONITRILE serves solely as a fragrance component, offering no direct skincare benefits, and while deemed low risk for skin sensitization at intended cosmetic concentrations, its pure form carries warnings for general irritation.
