Identification: 2-methylene-1, 3-propanediol diacetate
(CAS: 3775-29-9)
Appearance/Physical state: Clear colorless liquid
Batch: 20160308(-88)
Purity: 99.7%
Expiry date: 31 March 2019
Storage conditions: Room temperature in the dark
[Stored at approximate 4 °C between 02 September 2016 and 08 February 2017, room temperature after this time] - Key result
- Surface tension:
- 68.1 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: not surface active
- Conclusions:
- The mean surface tension of a duplicate solutions prepared at nominally 1 g/L test item in water has been determined to be 68.1 mN/m at 20.0 ± 1.0 °C. The test item was considered not to be surface-active.
- Executive summary:
The general physico-chemical properties of 2-methylene-1, 3-propanediol diacetate (CAS: 3775-29-9) have been determined.
Surface Tension- 1 g/L test item in water has been determined to be 68.1 mN/m at 20.0 ± 1.0 °C , using a ring method based on ISO 304, designed to be compatible with Method A5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. The test item was considered not to be surface-active.
