This invention provides an aqueous dewaxing reagent comprising the following components by weight percentage: 0.3-6% surfactant and 0.5-3% composite penetration enhancer, with the balance being water. The composite penetration enhancer is composed of limonene and terpineol, wherein the mass of terpineol is not less than 10% of the total mass of the composite penetration enhancer. The preparation method involves mixing the surfactant, composite penetration enhancer, and water. This invention utilizes a composite penetration enhancer composed of limonene and terpineol, which significantly improves dewaxing speed, reduces temperature dependence, widens the operating temperature window, reduces tissue damage, provides better protection against antigens, and is beneficial for IHC staining.
