Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
At standard conditions, phenol is an organic, colourless to yellow or light pink crystalline solid with a characteristic odour. Phenol has a melting point of 40.9°C and a boiling point of ca. 182°C. The density of phenol is reported to be 1.07 g/cm³ at 20°C and 1.13 g/cm³ at 25°C, respectively.
*According to Annex VII of Regulation (EC) No 1907/2006 (column 2) and the ECHA Guidance on Information Requirements and Chemical Safety Assessment, chapter R.7.1.14.1 (Information requirements on granulometry), an experimental study on the particle size distribution (granulometry) does not need to be conducted because the substance is marketed or used in a non solid or granular form.
Phenol has a vapour pressure of 0.2 hPa at 20 °C and a log Pow of 1.47 at 30°C (measured via HPLC). It has a water solubility of 84 g/L at 20°C. According to the classification scheme, phenol can be regarded as very soluble in water. Phenol has no surface-active properties ( 71.3 mN/m at 20°C; 0.118% (m/m) aqueous solution). The flash point of phenol determined via the German standard method DIN 51758 (closed cup) is reported to be 81°C. The auto-ignition temperature of phenol is 715°C. In the EU RAR, phenol as solid is charaterized as not highly flammable and as liquid as not flammable, not highly flammable and not extremely flammable. Moreover, according to REACH Regulation (Annex XI, 1.), a study does not need to be done if based on the available data the substance can be classified, labelled and/or the risk of the substance can be assessed. The experience in the use and testing for other REACH endpoints showed that the substance does not ignite spontaneously (not pyrophoric) in air or react violently with water and therefore testing according to EC Methods A.12 and A.13 is not scientifically necessary. According to REACH regulation (Annex VII, 7.11, column II), the study on explosiveness does not need to be done if the substance does not contain chemical groups indicating explosive properties. Phenol does not contain any chemical groups indicating explosive properties. According to REACH Regulation (Annex VII, 7.13, column II), the study on oxidising properties does not need to be done if the substance based on the chemical structure does not react exothermically with combustible substances. Phenol does not contain any functional groups indicating oxidising properties. According to REACH Regulation (Annex IX, 7.15, column I), the study on the stability in organic solvents and identity of relevant degradation products needs only to be done if the stability of the substance is regarded as a substantial property. The stability of phenol in organic solvents is not regarded as critical. The dissociation constant of phenol is 9.89 at 20 °C. The viscosity of phenol is reported to be 3.437 mPa x s at 50°C..
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
