Stability
Trimethylhexyl acetate demonstrates stability under typical conditions but requires storage away from strong oxidizing agents. As an ester, it will react with acids to liberate heat alongside alcohols and acids, with strong oxidizing acids potentially causing a vigorous, exothermic reaction. Heat is also generated upon interaction with caustic solutions, and mixing with alkali metals or hydrides can generate flammable hydrogen gas.

Safety
Safety Profile
The Research Institute for Fragrance Materials (RIFM) has completed a safety assessment for trimethylhexyl acetate concerning its use as a fragrance. However, the Cosmetic Ingredient Review (CIR) Panel is currently evaluating if this assessment is adequate for other cosmetic uses and exposures. An OECD 408, 90-day repeated dose toxicity study is planned to complete its ECHA REACH Dossier. It is classified with a GHS hazard statement H315, indicating it 'Causes skin irritation', and may also cause irritation to the skin and eyes upon direct contact.

Verdict
Given its classification as a skin irritant, ongoing safety evaluations, and primary role as a fragrance, Trimethylhexyl Acetate is a questionable inclusion for precision skincare formulations.
