【摘要】 研究发现化妆品防腐剂布罗波尔在水中会因pH增加、储存温度增高和放置时间的增长等因素,在水中缓慢分解且释放出少量甲醛。在含布罗波尔的化妆品中,采用乙酰丙酮比色法测得甲醛含量,比采用高效液相色谱法测得甲醛要高。此外,还发现28 d内的布罗波尔可释放甲醛的含量比较低,引起化妆品中甲醛超标的风险性较小。更多还原

【Abstract】 It was found that the cosmetic preservative bropol would slowly decompose and release a small amount of formaldehyde in water due to the increase of pH,storage temperature and storage time. In the cosmetics containing bronopol,the content of formaldehyde determined by acetylacetone colorimetry was higher than that determined by high performance liquid chromatography(HPLC). In addition,the content of formaldehyde released by bronopol within 28 days was relatively low,and the risk of excessive formaldehyde in cosmetics was small.更多还原
