乙醛（acetaldehyde）是一種有機(jī)化合物，分子式為C2H4O，無色液體，又名醋醛，無色易流動液體，有刺激性氣味，可與水和乙醇等一些有機(jī)物質(zhì)互溶。易燃易揮發(fā)，蒸氣與空氣能形成爆炸性混合物，爆炸極限4.0%～57.0%（體積）。
2017年10月27日，世界衛(wèi)生組織國際癌癥研究機(jī)構(gòu)公布的致癌物清單初步整理參考，與酒精飲料攝入有關(guān)的乙醛在一類致癌物清單中、乙醛在2類致癌物清單中。

Acetaldehyde is an organic compound with a molecular formula of C2H4O. It is a colorless liquid, also known as acetaldehyde. It is a colorless and easy-flowing liquid with a pungent odor. It is miscible with some organic substances such as water and ethanol. It is flammable and volatile, and the vapor and air can form an explosive mixture with an explosion limit of 4.0% to 57.0% (volume).
On October 27, 2017, the list of carcinogens published by the World Health Organization's International Agency for Research on Cancer was preliminarily sorted out for reference. Acetaldehyde related to the intake of alcoholic beverages is in the list of type 1 carcinogens, and acetaldehyde is in the list of type 2 carcinogens.



For the determination of acetaldehyde residues in cosmetics, Huohan Chromatography, advancing with the times, has developed a headspace gas chromatography method and an area external standard method for quantification, and the results are accurate and reliable. The vastness of chromatography provides detailed analysis solutions.
