Additional information

In the paper Johnson Jr. W., Safety assessment of Chlorphenesin as Used in Cosmetics, International Journal of Toxicology, 33 (Suppl.2),p.5-15, 2014 public on CIR website, the test item density of 0.70 - 075 was reported. No details regarding the method used for the test were reported in the secondary source but the primary source refers to British Pharmacopoeia method  (Primary source: Unilab Chemicals & Pharmaceuticals Pvt Ltd. Certificate of analysis and MSDS: Chlorphenesin BP (British Pharmacopoeia). Unpublished data submitted by the Personal Care Products Council on July 13, 2011; 2010:1-4). To confirm this data an estimated value for density for the smile Clc1ccc(OC(O)CCO)cc1 was calculated using the public software ACD/Labs Percepta Platform - PhysChem Module available with free ChemSketch version: the predicted value was 1.3 g/cm^3 at T=20 °C (equivalent to 1.3 relative density). The experimental data based on British Pharmacopoeia method  is prefered than predicted value. Both values are similar.
