Zusammenfassung:	The invention relates to a method for preparing lyral for detection of cosmetics. The method comprises steps as follows: (a) myrcenol and acrylaldehyde react; (b) a reaction mixture is washed with deionized water, and a lyral crude product is obtained; (c) the lyral crude product is rectified, lyral fractions at the temperature between 120-125 DEG C are collected, and refined lyral is obtained; (d) the lyral fractions are finely granulated, and lyral is obtained. The product has excellent physical and chemical characteristics and has excellent stability, particularly, volatilization stability. 本发明涉及制备化妆品检测用新铃兰醛的方法。该方法包括如下步骤：(a)使月桂烯醇与丙烯醛反应；(b)用去离子水洗涤反应混合物，得到新铃兰醛粗品；(c)将新铃兰醛粗品进行精馏，收集120℃～125℃之间的新铃兰醛馏分，得到精制的新铃兰醛；(d)使新铃兰醛馏分细颗粒化，即得。本发明产物呈现优异的理化特征，并且具有优异的稳定性尤其是优异的挥发稳定性。
