Description of key information
Additional information
Physico-chemical endpoints are completed for this substance based on test data following standard guidelines, or data waivers. All data are therefore considered to be reliable and relevant for the endpoint concerned.
Appearance / physical state / colour
4-Methyl-4-phenylpentan-2-ol is a colourless liquid at ambient temperature. The data are taken from substance identification information in an OECD 102, guideline study available as an unpublished report (Smeykal 2014).
Melting point/freezing point
4-Methyl-4-phenylpentan-2-ol has a melting point of -59.0 °C at 1013 hPa. The melting point was determined in a thermal analysis test, using differential scanning calorimetry following OECD guideline 102 (Smeykal 2014).
Boiling point
4-Methyl-4-phenylpentan-2-ol has a boiling point of 251.8 °C at 1013 hPa. The boiling point was determined in a thermal analysis test, using differential scanning calorimetry following OECD guideline 103 (Smeykal 2014).
Density
The relative density (4D20) of 4-Methyl-4-phenylpentan-2-ol at 20 ± 0.1 ºC (compared to water at 4 ºC) is 0.97.The relative density was determined with a calibrated oscillating densitimeter according to OECD guideline 109 (Smeykal 2014).
Granulometry
The particle size distribution test has been waived because the substance is not manufactured or used in a solid form.
Vapour pressure
The vapour pressure of 4-Methyl-4-phenylpentan-2-ol was determined to be 7.4 Pa at 20 °C, 10.6 Pa at 25 °C and 54.3 Pa at 50 °C. The vapour pressure of the test item was determined in a vapour/liquid equilibrium apparatus following OECD guideline 104 (Smeykal 2015).
Partition coefficient
The partition coefficient (log Pow) for 4-methyl-4-phenylpentan-2-ol was determined to be 2.82 at 23.8 ºC.The partition coefficient of the test item was determined using the HPLC method following OECD guideline 117 (Lange 2015).
Water solubility
The water solubility of 4-Methyl-4-phenylpentan-2-ol was determined to be 1.27 g/L at 20.0 ± 0.5 °C and pH 7.1.The water solubility of test item was determined in a GLP study (Lange 2015) following OECD guideline 105.
Surface tension
The surface tension of a 1 g/L aqueous solution of 4-Methyl-4-phenylpentan-2-ol was determined to be 44.12 mN/m (standard deviation ± 0.02) at 20 ºC. As the surface tension is < 60 mN/m, the test item is classified as a surface-active substance. The surface tension was determined using the harmonised ring method according to OECD guideline 115 (Thieu-Simchenl 2015).
Flash point
The flash point of 4-Methyl-4-phenylpentan-2-ol was determined to be 108.5 °C at 1013 hPa. The flash point of the test item was determined with a Rapid Tester NPV 310 apparatus using the close cup method which corresponds to the regulation EC 440/2008 Method A.9.(Smeykal 2014).
With a measured flash point ≥ 60°C the test item is not classified as a flammable liquid under GHS (CLP Regulation EC 1272/2008 Annex 1:2.6) or UN Transport Regulations. With a measured flash point ≥ 55 °C the test item is not classified as a flammable liquid under Regulation EC 440/2008 or Directive 67/548/EEC.
Auto-flammability
The auto-ignition temperature of 4-methyl-4-phenylpentan-2-ol was determined to be 420 °C at 1006.5 to 1018.3 hPa. The auto-ignition temperature of the test item was determined according to Regulation EC No. 440/2008 Method A.15. Auto-Ignition Temperature (Liquids and Gases) and DIN 51794 (2003): Determination of Ignition Temperature (Smeykal 2015).
According to DIN EN 13463-1 the test item is assigned to temperature class T2 (auto-ignition temperature ≥ 300°C - < 450 °C).
Flammability
The flammability study for 4-methyl-4-phenylpentan-2-ol has been waived as the substance is a liquid and flammability classification has been based on flash point data.
Explosiveness
Based on the structure of the substance, the explosiveness study has not been conducted as 4-methyl-4-phenylpentan-2-ol has no structural alerts that would indicate explosive properties.
Oxidising Properties
Based on the structure of the substance, the oxidising properties have not been conducted as 4-methyl-4-phenylpentan-2-ol has no structural alerts that would indicate oxidising properties.
Classification and labelling
The substance is not classified for physico-chemical hazards. Based on the structure of the substance, it does not meet the criteria for oxidising or explosive properties and based on experimental data, the substance does not meet the criteria for a flammable liquid. Experience in manufacture and handling shows that the substance is not a self-heating solid.
