Description of key information

Additional information

The testing strategy of this substance has been developed as part of a substance category the Primary Fatty Amine Ethoxylates. The substances all share the same chemical structure, with only a variation in the fatty amine alkyl chain length. It is expected that phys-chem ecotoxicological and toxicological properties vary within this category primarily based on the hydrophobic alkyl chain length.

Since the substance 2,2'-(C12-18 evennumbered alkyl imino) diethanol has the lowest molecular weight, it is also expected to have the highest vapour pressure and lowest flash point and autoignition point. These values has been used as a worst case value to represent all substances in the category.
