摘要
为了建立油包水型化妆品中pH值的测定方法,样品经过物理或化学方法破乳后测定pH值,测试结果运用仪器比对、人员比对、方法比对进行验证。结果显示该方法操作简便、实验结果可靠,弥补了现有方法不能测定油包水型化妆品pH值的不足。
A method for determining the pH value in water-in-oil cosmetics was established.After demulsification by physical or chemical methods,the pH value of the sample was measured.The results were verified by instrument comparison,personnel comparison,and method comparison.The method is simple to operate and the experimental results are reliable,which complements the existing method by measuring the pH value of water-in-oil cosmetics.
