主要成分 Main Component

白油（又称白色矿物油、液体石蜡、石蜡油）是石油润滑油馏分经深度脱蜡、加氢或化学精制得到的高纯度、无色、无味、透明的饱和烃混合物（主要为 C15–C40 正构与异构烷烃），化学惰性强、低毒、低芳烃、低硫。 White oil (white mineral oil / liquid paraffin / paraffin oil) is a highly purified, colorless, odorless, transparent saturated-hydrocarbon mixture obtained by deep dewaxing and hydro-/chemical-refining of petroleum lube fractions (mainly C15–C40 normal & iso-alkanes); chemically inert, low-toxicity, low-aromatic, low-sulfur.

杂质/副成分 Impurities

杂质受控：芳烃/多环芳烃(PAH)、易碳化物质、硫化合物、重金属（Pb/As）、水分、机械杂质、酸值、紫外吸收（260–350 nm）。食品/医药级控制更严。 Controlled impurities: aromatics/PAH, readily carbonizable substances, sulfur compounds, heavy metals (Pb/As), water, mechanical impurities, acid value, UV absorbance (260–350 nm); stricter for food/pharma.
