- Identification: PG-RAW-90-032
Chemical name: Reaction mass of (E)-1-(3,6-dimethylcyclohex-3-en-1-yl)-2-methylpent-1-en-3-one and (E)-1-(4,6-dimethylcyclohex-3-en-1-yl)-2-methylpent-1-en-3-one
CAS numbers: 2248118-61-6, 2248118-60-5
Appearance/Physical state: clear, colourless liquid
Batch: RDRW 534-93
Purity: 57.85% for constituents 1 and 2, 41.23% for consituents 3 and 4
Expiry / Retest date: 01 November 2020
Storage conditions: ~4 °C, in the dark - Key result
- Surface tension:
- 58.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 other: % saturation
- Conclusions:
- The surface tension at nominally 90 % saturation of test item in water has been determined to be 58.5 ± 0.5mN/m at 20.0 ± 0.5 °C. The test item was considered to be surface-active.
- Executive summary:
The determination was carried out by a ring method, using a procedure designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for the Testing of Chemicals, 27 July 1995.
The surface tension at nominally 90 % saturation of test item in water has been determined to be 58.5 ± 0.5mN/m at 20.0 ± 0.5 °C. The test item was considered to be surface-active.

Description of key information
The determination was carried out by a ring method, using a procedure designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for the Testing of Chemicals, 27 July 1995.
The surface tension at nominally 90 % saturation of test item in water has been determined to be 58.5 ± 0.5mN/m at 20.0 ± 0.5 °C. The test item was considered to be surface-active.
Key value for chemical safety assessment
- Surface tension:
- 58.5
Additional information
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.
