摘 要 建立了高效液相色谱法准确、快速、灵敏测定化妆品中11种紫外吸收剂的方法。采用C18色谱柱,以乙腈和0.1%甲酸作为流动相, 311 nm作为检测波长,在11.5 min内完成11种紫外吸收剂的基线分离。在优化的实验条件下,目标化合物的保留时间和峰面积的相对标准偏差分别小于0.05%和1.20%;另外,所有目标化合物的检出限均低于2.24 mg/L, 并在5~500 mg/L 内均具有良好的线性关系

1 引 言

太阳光中紫外线可分为紫外线A (400~320 nm)和紫外线B (320~290 nm),以及紫外线C (280 nm以下)。通常,295 nm以下的光线不能到达地表,所以到达人体皮肤的是前两个波段的紫外线[ 1,2]。紫外线会导致皮肤晒黑、晒伤,甚至会诱发皮肤癌。因此,生产厂商会添加一定量紫外吸收剂于具有防晒功能的防晒霜、隔离霜等化妆品中。但是过量的紫外吸收剂影响人体健康。2007版《化妆品卫生规范》行业标准对防晒化妆品中的紫外吸收剂进行了限制[ 3];世界主要化妆品生产和消费国都对化妆品中的紫外吸收剂的种类和使用量进行了规定[ 3,4]。不同国家对化妆品中紫外吸收剂的限用量差别较大,比如甲氧基肉桂酸异戊酯已经得到欧盟批准使用,但日本禁止将甲氧基肉桂酸异戊酯与一些特定成分一起使用[ 5]。

测定化妆品中紫外吸收剂的方法主要有薄层色谱法[ 5]、气相质谱法[ 6]和高效液相色谱法[ 7~13]和电化学法[ 14]。其中,高效液相色谱法是检测化妆品中紫外吸收剂中使用最为广泛的方法。在2002版《进口化妆品中紫外吸收剂的测定 液相色谱法》这一行业标准中,对对氨基苯甲酸等8种紫外吸收剂测定,该标准采用甲醇、四氢呋喃和水的混合溶液作为流动相,而四氢呋喃除了具有较大的毒性外,还容易引起色谱系统不稳定,峰拖尾和鬼峰产生等问题[ 11]。并且2002版行业标准并未对样品进行测定,虽然有一些文章已报道实际样品的测定,但测定的紫外吸收剂种类较少,导致市场上化妆品中紫外吸收剂的添加量仍存在较大不确定性[ 7~10]。

因此, 建立一种简便、能准确测定化妆品中紫外吸收剂的方法,并将其应用于市场上化妆品中紫外吸收剂的测定是十分必要的。本研究拟采用常用的高效液相色谱法,在不使用四氢呋喃的条件下,对化妆品中的2羟基4甲氧基二苯甲酮5磺酸、对氨基苯甲酸、2,2,4,4四羟基二苯甲酮、3,3,5三甲基环已烷水杨酸酯等11种紫外吸收剂进行同时测定。

4 结 论

本方法采用简单流动相,在11.5 min 内即可完成化妆品中11种紫外吸收剂的基线分离和准确测定。该方法具有快速、准确、可靠的特点,适用于隔离霜和防晒霜等化妆品中多种紫外吸收剂的测定,为规范紫外吸收剂在化妆品中的使用提供技术支持。

Abstract An accurate, fast and sensitive method based on high performance liquid chromatography was established for the simultaneous determination of eleven ultraviolet absorbents in cosmetics. Eleven ultraviolet absorbents were baseline separated on an Acclaim C18 column within 11.5 min using acetonitrile0.1% formic acid in water (V/V) mobile phase, and detected at 361 nm with UV detection. Under the optimized conditions, the relative standard derivations (RSDs) of the eleven ultraviolet absorbents were all less than 0.1% for retention time, and less than 1.2% for peak area; good linearity was obtained from 5 to and 500 mg/L with the correlation coefficients of above 0.9990 for these analytes; the recoveries spiked in a cosmetic sample were in the range of 77%-116%. Benzophenone3, butylmethoxydibenzoylmethane, ethylhexylsalicylatec and homosalate were found in the detected cosmetic samples, and the concentration of homosalate was the highest. The results indicated that this method had potential for applications due to its convenience, accuracy and sensitivity. Oxybenzone, butylmethoxydibenzoylmethane, 2ethylhexyl salicylatec and homosalate were found in the detected cosmetic samples, and the concentration of homosalate was the highest.
