Description of key information

Additional information

As a pure substance, dicyclohexylamine occurs only in the form of the free amine. Protonated dicyclohexylamine is an ammonium salt which is refered to as the protonated form. For clarity, when the protonated form is meant, this is indicated in the test substance field. In the aquatic environment, dicyclohexylamine is mostly in its protonated form. The exact extent of protonation depends on the pH and other parameters. Aquatic test data have always been determined in solutions containing both forms. Aqueous solutions of dicyclohexylamine are refered to as dicyclohexylamine, independently of the predominant form.
