The separation was performed using an uncoated fused-silica capillary (50 \u03bcm id \u00d7 60.2 cm, effective length 50 cm) with a running buffer consisting of 15 mmol\/L sodium tetraborate, 60 mmol\/L boric acid, and 100 mmol\/L sodium dodecyl sulfate. A 1:10 dilution of the running buffer was used as the sample buffer to extract the cosmetic samples. The key factors, such as the concentration and pH of the running and sample buffers, which influence quantitative analysis of the above 11 preservatives in cosmetic samples, were investigated in detail. The linear ranges of the calibration curves for imidazolidinyl urea and the other 10 preservatives were 50\u20131000 and 10\u2013200 mg\/L, respectively. The correlation coefficients of the standard curves were all higher than 0.999. The recoveries at the concentrations studied ranged from 93.0 to 102.7%. RSDs were all less than 5%. The new method with simple sample pretreatment met the needs for routine analysis of the 11 preservatives in cosmetics.<\/jats:p>","DOI":"10.5740\/jaoacint.11-043","type":"journal-article","created":{"date-parts":[[2012,8,13]],"date-time":"2012-08-13T15:26:13Z","timestamp":1344871573000},"page":"1069-1073","source":"Crossref","is-referenced-by-count":20,"title":["Simultaneous Determination of Eleven Preservatives in Cosmetics by Micellar Electrokinetic Chromatography"],"prefix":"10.1093","volume":"95","author":[{"given":"Ping","family":"Wang","sequence":"first","affiliation":[{"name":"Beijing Center for Disease Control and Prevention, Beijing 100013, People\u2019s Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaojing","family":"Ding","sequence":"additional","affiliation":[{"name":"Beijing Center for Disease Control and Prevention, Beijing 100013, People\u2019s Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun","family":"Li","sequence":"additional","affiliation":[{"name":"Beijing Center for Disease Control and Prevention, Beijing 100013, People\u2019s Republic of China Capital Medical University, Department of Public Health and Domestic Medicine, Beijing 100069, People\u2019s Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Uanyuan","family":"Ang","sequence":"additional","affiliation":[{"name":"Beijing Center for Disease Control and Prevention, Beijing 100013, People\u2019s Republic of China Agricultural University of Hebei, College of Food Science and Technology, Baoding 071001, People\u2019s Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2019,11,27]]},"container-title":["Journal of AOAC INTERNATIONAL"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/95\/4\/1069\/32423635\/jaoac1069.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/95\/4\/1069\/32423635\/jaoac1069.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,19]],"date-time":"2020-03-19T14:10:36Z","timestamp":1584627036000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jaoac\/article\/95\/4\/1069-1073\/5655180"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,7,1]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2019,11,27]]},"published-print":{"date-parts":[[2012,7,1]]}},"URL":"https:\/\/doi.org\/10.5740\/jaoacint.11-043","relation":{},"ISSN":["1060-3271","1944-7922"],"issn-type":[{"value":"1060-3271","type":"print"},{"value":"1944-7922","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2012,7,1]]},"published":{"date-parts":[[2012,7,1]]}}}
