甲醇在人體有蓄積作用,主要經(jīng)呼吸道、胃腸道和皮膚吸收,其最終代謝產(chǎn)物為甲醛和甲酸.近年研究表明,甲醛很快代謝成甲酸,急性中毒引起的代謝性酸中毒和眼部損害,主要與甲酸含量相關(guān).因甲醇的毒性較強(qiáng),故我國化妝品衛(wèi)生標(biāo)準(zhǔn)規(guī)定甲醇為限用物質(zhì).在保健用品中的允許濃度為2 000 mg/kg

Methanol accumulates in the human body and is mainly absorbed through the respiratory tract, gastrointestinal tract, and skin. Its final metabolites are formaldehyde and formic acid Recent studies have shown that formaldehyde is rapidly metabolized into formic acid. Metabolic acidosis and eye damage caused by acute poisoning are mainly related to formic acid content Due to the strong toxicity of methanol, the hygiene standards for cosmetics in China stipulate that methanol is a restricted substance The allowable concentration in healthcare products is 2000 mg/kg
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd.: Establish a rapid and sensitive methanol determination method. Method: The degree of temperature rise gas chromatography was used to determine methanol in cosmetics. Result: The separation of methanol has been greatly improved, with better precision than the current national standard. Conclusion: This method has the characteristics of good reproducibility, high accuracy, stability, and speed.
