Use of read-across to fill data gaps for the subject of Registration, Neononanoic acid glycidyl ester (2,3 -epoxypropyl neonoanoate) CAS No. 144548 -01-6, from 2,3 -epoxypropyl neodecanoate ( EC No. 247-979-2/CAS No. 26761-45-5/REACH Registration: 01-2119431597-33-0000) is justified in the attachment. Based upon the use of read-across the Auto Ignition Temperatue of Neononanoic acid glycidyl ester is 276 ± 5 °C. Read-across to data for 2,3 -epoxypropyl neodecanoate was also used for Surface Tension determination. The surface Tension of a 90% saturated solution of the test substance was 45.3-48.9 mN/m at 21-22 °C. Therefore the test substance is considered to be surface active.

Other physicochemical parameters were determined experimentallt for the test substance and included: A freezing point of lower than -80°C and boiling point determined to be 253.6°C at 29.8 inHg. The extrapolated vapor pressure was detennined to be 0.0965 Pascals at 20°C and 0.2171 Pascals at 25°C. The solubility in water of the test substance was determined to be 152 mg/L and the partition coefficient (P0w) was determined to be 2900 with a Log Pow. of 3.47. The specific gravity of the test substance was determined to be 0.97 (20/20,). The viscosity of the test substance was determined to be 7.50 cSt at 20°C and 4.80 cSt at 40°C and flash point was determined to be >95.1°C.
