Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If higher acyclic alcohol classification
Longer chain lengths sometimes grouped differently in statistical reporting.
If solvent-grade with additives
Additives for end-use render it a preparation rather than pure compound.
If surface-active formulations
Surfactant mixtures containing diols fall under Chapter 34.
