Additional information

The substance is a complex UVCB, which costituents are either oils, with a negligible vapour pressure and water. The measured vapour pressure can only be the value referred to water at 20 °C. Literature reports vapor pressure of water as about 2.34 kPa at 20 °C. This value is confirmed by the result is from the chemically similar EC 269-123-7, castor oil, sulphated substance that is a member of the sulfated fat liquors category. Testing followed IQS-STANG-PNT-A-0116 protocol by the static method
