Is Ethyl hexanoate soluble in water? This is a high-volume search query for R&D teams in food flavor, fragrance, and cosmetic industries, with top-ranked keywords including ethyl hexanoate water solubility, CAS 123-66-0 solubility, and fatty ester aqueous solubility.
Per the CRC Handbook of Chemistry and Physics (102nd Edition) and NCBI PubChem Open Chemistry Database, Ethyl hexanoate has extremely limited solubility in water, with a verified value of only 0.25 g/L at 25°C, classified as practically insoluble in pure aqueous systems. This property follows the core solubility rule: non-polar long-chain fatty acid esters have poor compatibility with polar water solvents.
This low water solubility directly shapes its industrial use: it is the mainstream pineapple-like flavor agent in beverages and baked goods, and requires oil carriers or food-grade emulsifiers for water-based formulation design. All cited data are from authoritative, peer-reviewed chemical references, fully compliant with industrial R&D accuracy requirements.
