用于检测化妆品中槟榔碱的标准物质的配制方法
摘要：
本发明涉及用于检测化妆品中槟榔碱的标准物质的配制方法，其特征在于：将槟榔碱的丙二醇溶液与化妆品膏霜混合，形成用于检测化妆品中槟榔碱的标准物质，其中，化妆品膏霜的配方按重量百分比计为：A相：硬脂酸酯3-5；十六十八醇2-4；26#白油10-14；B相：丙二醇38-42；卡波姆0.1-0.3；去离子水36-42；C相：三乙醇胺0.1-0.3；D相：苯氧乙醇及乙基己基甘油1.25-1.30；所述槟榔碱在标准物质中的浓度达到50μg/g。优点是：将槟榔碱与化妆品膏霜混合，形成用于检测化妆品中槟榔碱的标准物质，该标准物质与实际使用时含有槟榔碱的化妆品样品相同，从而使得对化妆品中槟榔碱的检测更符合实际应用的状态，并且使检测更兼准确。
摘要（英）：

The invention relates to a preparation method of a standard substance for detecting arecoline in a cosmetic. The preparation method is characterized in that a propylene glycol solution of the arecoline is mixed with cosmetic cream to form the standard substance for detecting the arecoline in the cosmetic. The formula of the cosmetic cream comprises a phase A, a phase B, a phase C and a phase D in percentage by weight, namely the phase A comprises 3 to 5 percent of stearate, 2 to 4 percent of alcohol and 10 to 14 percent of #26 white oil; the phase B comprises 38 to 42 percent of propylene glycol, 0.1 to 0.3 percent of carbomer and 36 to 42 percent of deionized water; the phase C comprises 0.1 to 0.3 percent of triethanolamine, and the phase D comprises 1.25 to 1.30 percent of phenoxyethanol and ethylhexylglycerin; and the concentration of the arecoline in the standard substance is 50 mug/g. The preparation method has the advantages that the arecoline is mixed with the cosmetic cream to form the standard substance for detecting the arecoline in the cosmetic; the standard substance is the same as that in a cosmetic sample containing the arecoline in actual use, so that detection on the arecoline in the cosmetic can accord with an application state; and the detection is relatively accurate.
