- 1. HYPOTHESIS FOR THE ANALOGUE APPROACH
Common functional groups and similar composition.
EP-4000s and the registered substance are very similar. They are UVBC substances and both are oligomeric reaction products of 4,4'-propane-2,2-diyldiphenol and 2-methyloxirane and 2-(chloromethyl)oxirane where constituents are structurally related. EP-4000s contains less than 0.1% monochlorinated constituents while the registered substance contains approximately 10% monochlorinated constituents. As these are otherwise structurally similar to other constituents it can be reasonably expected that EP-4000s and the registered substance will have essentially the same properties.
2. SOURCE AND TARGET CHEMICAL(S) (INCLUDING INFORMATION ON PURITY AND IMPURITIES)
EP4000s:
Purity 79.7-90%, 3 main components F, E, C
Impurities:
5 known by-products 18%
6 unknown impurities 2.4%
Water 0.1%
Chlorinated impurities <0.1%
Aliphaticdiol diglycidyl ether:
Purity 92.57%, 3 main components F, E, C
Impurities:
5 known by-products (same identity as EP-400s) 14.37%
Water none
Two new impurities (I and J) 10.48% in total
Further details are provided in Section 13 Assessment Reports
3. ANALOGUE APPROACH JUSTIFICATION
Read across all data – the presence of one chlorine atom in components comprising 10% of a relatively high molecular weight mixture will not have a significant effect on physicochemical properties. Furthermore, alky halides are known to have fire retardant properties and therefore impurities I and J will not confer any flammable properties. It is noted that the log Pow is determined on the three main components of EP-4000s which means if the test was repeated on the Aliphaticdiol diglycidyl ether the result would be the same as both substances have the same three main components.
Overall conclusion – no new information would be gained by testing Aliphaticdiol diglycidyl ether for physicochemical properties.
4. DATA MATRIX
Not applicable – read across based on similar composition for all physicochemical endpoints.
Purity 92.57%, 3 main components F, E, C
Impurities:
5 known by-products (same identity as EP-400s) 14.37%
Water none
Two new impurities (I and J) 10.48% in total
Further details are provided in Section 13 Assessment Reports - Reason / purpose for cross-reference:
- read-across source

- Guideline:
- EU Method A.9 (Flash-Point)
- Deviations:

- ISO 2719 (Determination of flash point - Pensky-Martens closed cup method)
- Version / remarks:
- 2002
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:

- Conclusions:
- After correction for the atmospheric pressure, the flash point was determined to be 167 °C at 101.3kPa.
Reference
In the preliminary test, a flash point of about 170°C was found. Therefore (flash point above 65°C expected), the main study was performed using the Pensky-Martens flash point tester.
The flash point was measured at each temperature with an increment of 2 K.
The main test was performed in duplicate.
A clear flash point was observed at a test item temperature of 166°C during both tests at the actual atmospheric pressure of 98.2 kPa.
Description of key information
The flash point of Aliphaticdiol diglycidyl ether is 167°C at 101.3kPa using the Pensky-Martens closed cup flash point apparatus.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 167 °C
Additional information
A determination of the flash point was conducted (RCC Ltd) according to the Pensky-Martens closed cup method.
In the preliminary test, a flash point of about 170°C was found.The main test was performed in duplicate. A clear flash point was observed at a test item temperature of 166°C during both tests at the actual atmospheric pressure of 98.2 kPa. After correction for the atmospheric pressure, the flash point of ADEKA RESIN EP-4000S was determined to be 167 °C at 101.3kPa.
The value of 167°C for the flash point of EP-4000s will be taken as the value for Aliphaticdiol diglycidyl ether.
Justification for read across justification - EP-4000s and Aliphaticdiol diglycidyl ether are very similar substances. They are UVBC subtances and both are oligomeric reaction products of 4,4'-propane-2,2-diyldiphenol and 2-methyloxirane and 2-(chloromethyl)oxirane where constituents are structurally related. EP-4000s contains less than 0.1% monochlorinated consitiuents while Aliphaticdiol diglycidyl ether contains approximately 10% monochlorinated constituents, but as these are otherwise structurally similar to other constituents it can be reasonably expected that EP-4000s and Aliphaticdiol diglycidyl ether will have essentially the same physicochemcial properties.
Based on the flash point value of 167 °C at 101.3kPa, Aliphaticdiol diglycidyl ether does not meet the classification criteria for a flammable liquid.
