Additional information

2-butyne-1,4-diol, ethoxylated (>1 < 4.5 mol EO) is an essentially non-volatile, slightly viscous liquid (vapour pressure 0.000013 hPa at 20ºC) at room temperature, fully miscible with water and with a log POWof < 1.6 to 4.3 at 23°C and pH 6.2. There are no experimental studies on the toxicokinetics of 2-butyne-1,4-diol, ethoxylated (>1 < 4.5 mol EO).
