Stability

This compound exhibits good stability under normal storage conditions but is susceptible to hydrolysis in the presence of strong acids or bases. While its odor stability is robust across typical pH ranges found in shampoos (pH 6), APC (pH 9), fabric detergents (pH 9), and soaps (pH 9), performance deteriorates with bleaches and certain soap formulations. Its inherent high volatility necessitates strategic formulation, such as encapsulation or the inclusion of fixatives, to ensure prolonged aromatic presence. Its limited water solubility requires careful integration into aqueous systems.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

Ethyl 2-methylbutyrate is not characterized by a 'known type of toxicity' and is not considered a substance of high concern for human health. Testing indicates no irritation to the skin, eyes, or respiratory tract, and it is not classified as corrosive. A RIFM Expert Panel concluded it does not present a concern for genotoxicity. The FDA has designated it as Generally Recognized As Safe (GRAS) (FEMA 2443) for use as a flavoring agent in food. For fragrance applications, recommended usage levels are typically 0.1-2% in fine fragrance, with optimal impact observed at 0.5-1%.
