Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Stability in organic solvents and identity of relevant degradation products
Administrative data
- Endpoint:
- stability in organic solvents and identity of relevant degradation products
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the stability of the substance is not considered to be critical

Results and discussion
Applicant's summary and conclusion
- Conclusions:
- Considering REACH Annex IX 7.15 criteria, the stability in organic solvents and the identity of relevant degradation products should be assessed. According to the composition of this UVCB, to the literature and to the SEPPIC’s knowledge, the substance “Acetalization products between glucose and C16/18 alcohol” could be reasonably considered as stable in a wide range of organic solvents. By stable, we mean no chemical degradation of any of components of the substance. The substance is perfectly stable in aprotic solvent such as dimethylformamide, dimethylsulfoxide, ether, alkane and organochloride. In solvents such alcohols, a reaction could theoretically occur at high temperature ( > 110°C) with an acidic catalyst which could lead to a modification of the composition of the substance by forming short chain corresponding alkyl glucosides. However, in standard condition, neither degradation nor modifications were observed. To the best of our knowledge, there is no experimental account about any degradation of the substance in any solvents. That is why we thought there is no need to make the aforementioned test performed. This test does not need to be proposed.
