- Executive summary:
In a study conducted according to ASTM Standard Method D4052-96, the density of EC# 434-650-5 test material was determined using an oscillating tube digital density analyser maintained at a constant temperature in a circulating water bath. The instrument was calibrated with air and water at the test temperature.
The density was determined to be 1.0462 g/ml at 15.56oC.

Description of key information
There are 2 reliable studies available on EC:434 -650 -5.
One study (2000) was conducted in compliance with EEC Methods A3 and OECD guidelines for testing of chemicals (OECD 109) and to GLP. The relative density of EC: 434 -650 -5 was determined to be 1.07
A second study (1999) was conducted according to ASTM Standard Method D4052-96, the density of EC# 434-650-5 test material was 1.0462 g/ml at 15.56oC.
Both of these studies have shown very similar density values. For the purposes of the chemical safety assessment, the value of 1.07 will be used as this is the most recent study conducted to the OECD guideline.
This material is very similar in structure to the Registration material and the results can be read-across to EC 457-320-2.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.07
