Ethylparaben belongs to the paraben family of chất bảo quảns and is được sản xuất bởi esterification of para-hydroxybenzoic acid with ethanol. It exhibits broad-spectrum antimicrobial activity, with particular effectiveness against molds and yeasts across a wide pH range. Ethylparaben is more lipophilic than methylparaben.
This gives it enhanced efficacy in oil-containing food systems. It is commonly used in combination with other parabens to achieve synergistic preservation and broader antimicrobial coverage. Ethylparaben's độ ổn định under heat sterilization conditions and wide effective pH range make it a reliable chất bảo quản for thermally processed foods.
