- Executive summary:
A study was conducted to determine the boiling point of the read-across substance ‘glycerides, C16-18 and C18-unsatd., deodorizer distillates'. The study was conducted according to OECD Guideline 103, EU method A.2 and OPPTS 830.7220). The test was run through a by capillary method (Siwoloboff) using an electronic controlled heating system. In the preliminary test, the number of the air bubbles increased at about 300°C. To confirm the results obtained in the preliminary test, the determination of the boiling point was performed in triplicate, heating quickly up to 285°C and afterwards slowly using a heating rate of 1°C /min. Under the study conditions, the boiling point of the substance was determined to be 302°C at ambient barometric pressure (101.3 kPa) (Fieseler, 2010g). Based on the results of the read across study, the boiling point of the test substance, Soaps, stocks, vegetable oil, acidulated is considered to be 302°C at ambient barometric pressure (101.3 kPa)

- Executive summary:
A study was conducted to determine the boiling point of the read across substance 'oils, vegetable, deodorizer distillates' according to the OECD Guideline 103, EU Method A.2 and OPPTS 830.7220. The test was performed through the capillary method (Siwoloboff) using an electronic controlled heating system. In the preliminary test, the number of the air bubbles increased at about 331°C. To confirm the result obtained in the preliminary test, the determination of the boiling point was performed in triplicate, heating quickly up to 316°C and afterwards slowly using a heating rate of 1°C /min. A clear boiling point, as defined in the guideline with a current stream of bubbles evolving from the capillary, was observed at a heating temperature of 330°C. Under the study conditions, the boiling point of the read across substance was determined to be 331°C (604 K) at ambient barometric pressure (101.3 kPa) (Fieseler, 2010e). Based on the results of the read across study, the boiling point of the test substance, Soaps, stocks, vegetable oil, acidulated is considered to be 331°C (604 K) at ambient barometric pressure (101.3 kPa).
