Any other information on results incl. tables

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.
