Applicant's summary and conclusion
- Conclusions:
- The relative density D (ambient T/4°C) is 1.1
- Executive summary:
The relative density of acylglycinate GCK-12H -T (dry matter) was investigated in a study conducted according to OECD Guideline 109 (Density of Liquids and Solids) and EU Method A.3 (Relative Density) and using the pycnometer method. In a preliminary test the measurement showed an unusual behavior: the measured pressures did not reach steady state. Therefore the test item was dried under vacuum and at 50°C for up to 71 h before measurement and using different amounts of the test item. The relative density of the test item at ambient temperature compared to water at 4°C was determined to be D (ambient T/4°C)=1.1. Because of the unusual behavior of the test item the final result is only given with one decimal.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
