Executive summary:

The aim of the study was to determine the physico-chemical properties for 2,2'-methylenebis[6-(1-methylcyclohexyl)-p-cresol].

 

The study was based on the following guidelines:

European Community (EC), EC no. 440/2008, Part A: Methods for the Determination of Physico-Chemical Properties, Guideline A.3: “Relative Density”, Official Journal of the European Union no. L142, May 31, 2008.

Organization for Economic Co-operation and Development (OECD), OECD Guideline for the Testing of Chemicals no. 109: "Density of Liquids and Solids", October 2, 2012.

United States Environmental Protection Agency (EPA), Product Properties Test Guidelines no. OPPTS 830.7300: "Density/Relative Density/Bulk Density", June 2002.

 

A gas comparison stereopycnometer was used for the determination of the density and relative density of 2,2'-methylenebis[6-(1-methylcyclohexyl)-p-cresol].

 

The density of the test substance at 20°C was 1.13 g/cm3(1.13 x 103 kg/m3).

The relative density was 1.13.
