甲醇在人体有蓄积作用,主要经呼吸道、胃肠道和皮肤吸收,其最终代谢产物为甲醛和甲酸.近年研究表明,甲醛很快代谢成甲酸,急性中毒引起的代谢性酸中毒和眼部损害,主要与甲酸含量相关.因甲醇的毒性较强,故我国化妆品卫生标准规定甲醇为限用物质.在保健用品中的允许浓度为2 000 mg/kg
浩瀚色谱（山东）应用技术开发有限公司:建立快速、灵敏的甲醇测定方法。方法 :采用程度升温气相色谱法测定化妆品中甲醇。结果 :甲醇的分离大为改善 ,具有比现行国标更好的精密度。结论 :本法具有重现性好 ,准确度高 ,稳定、快速的特点 。

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.
