| Abstract: | Objective：To establish density bottle method to evalu-ate uncertainty in determination of relative density of smoothing toner. Method：According to JJF1059.1-2012 evaluation and ex-pression of uncertainty in measurement and GB/T 13531.4 2013 general methods on determination of cosmetics-determination of relative density, measurement model was established, and cause-effect diagram of sources of uncertainty was drawn up, and each component of uncertainty was calculated and classified, the expanded uncertainty was U=0.0002. Result：The results of rela-tive density of smoothing toner was 1.009 7±0.000 2. Conclu-sion：The study can provide reference basis for uncertainty eval-uation in determination of relative density. |
