Description of key information
Auto-ignition temperature: >276°C at 99.17 - 100.85 kPa (EU Method A.15)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 276 °C
Additional information
There are no measured auto-ignition temperatures for the registered substance, TOS. Therefore, auto-ignition temperature data has been read-across from the analogue substance, Crude Tall Oil (CTO).
Crude Tall Oil (CTO) is formed by acidification of Tall Oil Soap (TOS), therefore, CTO and TOS are similar UVCB substances. They differ only in the water content and that CTO does not contain sodium salts of the fatty/rosin acids. The main constituent blocks for TOS are sodium salts of saturated and unsaturated C14-C20 fatty acids (5-45% w/w), rosin acid sodium salts (10-40% w/w), water (25-45% w/w), sterols (1-10% w/w), and non-volatile lignin/cellulose fibre/oligomeric acids (3-20% w/w). In addition, the following minor constituent blocks are present: terpenes, sesquiterpenes, abietenes and labdanes, C30 branched polyalkenes, 3,5-dimethoxystilbene, rosin alcohol and aldehyde isomers and saturated/unsaturated alcohols and terpene alcohols (each <3%).
The same constituents are present in CTO, with only the following differences:
- The fatty acids and rosin acids in Tall Oil Soap (TOS) are present as their sodium salts whereas for Crude Tall Oil (CTO) they are present as acids. In aqueous media, the sodium salts are dissociated into sodium and the parent acid. The sodium, being a ubiquitous and essential element in nature, is not expected to contribute to the toxicity and/or flammability properties of the substance.
- TOS contains 25-45% water compared to trace amounts in CTO; other constituent groups are therefore present at lower levels but in similar proportions. Since both substances are UVCBs, impurities are not relevant as part of the chemical safety assessment.
A reliable auto-ignition temperature value of 276°C at 99.17 - 100.85 kPa has been determined for CTO using an appropriate test method (EU Method A.15) and in compliance with GLP. TOS has a higher amount of water and lower amount of terpenes (volatiles constituents) compared with CTO and as such, it is expected that the auto-ignition temperature of TOS will be greater than that of CTO. Therefore, the auto-ignition temperature of TOS is reported as greater than the value determined for CTO i.e. >276°C for the purpose of the chemical safety assessment. This conclusion is supported by the observation in the differential scanning calorimetry studies conducted for samples of the registered substance. In these studies, limited loss of volatile fractions from about 100°C (373 K) was observed, with formation of significant residue with boiling point >400°C (>673 K) reported. Therefore, it can be concluded that self-heating of the substance can be excluded for the registered substance up to 400°C.
There is a strong overlap between CTO and TOS in terms of the chemical constituents present and hence, to an extent and where justified, available data for CTO is considered relevant to be read-across to TOS.
