Pretreatment and Determination of Dissolvable Zinc Salt in Deodorizing Cosmetics / 环境与健康杂志

Objective To explore a method for determination of dissolvable zinc salt in deodorizing cosmetics. Methods The contents of dissolvable zinc salt in deodorants extracted by pure water were detected by flame atomic absorption spectrophotometry. Results The correlation coefficient of the standard curve was more than 0.999. The detection limit, precision and recovery rates of the method were 8.2?10-3 ?g, 1.26% and 97.0%～98.5% respectively. The lowest detection limit of zinc salt was 2.7?10-2 ?g. No other interfering factors were found during detection process. Conclusion This method could meet the requirements of hygienic physico_chemical detection for cosmetics.
