Batch Number                         B/406728

Material                                  100% Solid

Tested                                    December 2009                      

Estimated Boiling Point          220ºc to 420ºc

Scan speed                            temperature program of 20 ºc per minute

Instrument                              Mettler Toledo DSC 0822

Conclusions:

The boiling temperature of the test material has been estimated to be 220 °C - 420 ° at 101.6 kPa.

Executive summary:

The determination was carried out by differential scanning calorimetry (DSC) using the procedure specified in ASTM E537-86, Method A2 Boiling Temperature of Council Regulation (EC) No 440/2008 of 30 May 2008.

The Argowax (Lanolin Alcohols) was prepared for analysis using Differential Scanning Calorimeter (DSD) pans. The samples were analysed using a DSC using temperature prgram of 20 °C per minute. The objective was to determine physical properties for both chemicals for REACH data.

From the measurements obtained the boiling point and decomposition characteristics have been estimated. As the samples are a complex mixture (UVCB) rather than pure materials the boiling point and decomposition points can only be estimated as a range rather than an actual result.

Conclusions:

Executive summary:

 

The boiling point of the test material was determined using differential scanning calorimetry (DSC). The method was designed to be compatible with EU Method A.2., OECD 103 and EPA OPPTS 830.7220.

A preliminary test was performed using a thermogravimetric analyser. 3.24 mg of the test item was heated at a rate of 20 °C/minute to 429 °C. At this point 70 % weight loss of the test item was observed. After the experiment, the sample was cooled and equilibrated at 75 °C and the consistency of the test item was determined.

Two experiments were performed during the main test. The differential scanning calorimetry (DSC) curve obtained with Experiment 1.  During cooling, multiple glass transitions between 20°C and -60°C were found.  During heating multiple glass transitions were observed between -50°C and 50°C followed by an endothermic effect starting at 175°C.  The endothermic effect was probably obtained due to reaction and/or decomposition of the test item. After the experiment, an orange molten residue remained in the sample container (original colour: yellow).  The change of the colour indicated reaction and/or decomposition of the test item.   To investigate the multiple glass transitions between -50°C and 50°C, a repeated heating cycle was applied in Experiment 2.  The value of the first and second cooling/heating cycles were similar to what was found in Experiment 1.  This demonstrated that glass transition of the test item was the reason for these effect.  Since the test item is a mixture, the glass transition was obtained from the temperature of start of the first effect (-50 °C) and of the last effect (50 °C).  

Reaction and/or decomposition of the test item was observed during DSC experiment at temperatures of > 175 °C (> 448K). Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.
