- Executive summary:
A study was conducted to determine the relative density of the read-across substance ‘glycerides, C16-18 and C18-unsatd., deodorizer distillates' using the gas comparison method according to OECD Guideline 109, EU Method A.3 and EPA OPPTS 830.7300. The determination of the relative density was performed by three- fold measurement of two independent read across substance samples at a temperature of 20 ± 1.0°C. Under the study conditions, the relative density of substance was determined to be 0.945 at 20°C (Fieseler, 2010k). Based on the results of the read across study, the relative density of the test substance, Soaps, stocks, vegetable oil, acidulated is considered to be 0.945 at 20°C.

- Executive summary:
A study was conducted to determine the relative density of 'oils, vegetable, deodorizer distillates' according to OECD Guideline 109, EU Method A.3 and EPA OPPTS 830.7300. The density of the read across substance was determined from the difference in weight between the full and empty pycnometer and its known volume. The determination of the relative density was performed by three-fold measurement of three independent read across substance samples. Under the study conditions, the relative density of read across substance was determined to be 0.905 +/- 0.1 at 20°C (Fieseler, 2010i).
