Description of key information

pKa of ammonia: 9.25 at 25 °C
pKa of alkyl ether sulfate: 1.24 at 20 °C

Key value for chemical safety assessment

Additional information

Due to the dissociation constants of the corresponding alkyl ether sulfate (pKa < 2) and the ammonia (pKa = 9.25), it can be assumed that the substance is existent as a salt and thus completely dissociated in the range of pH 5 -9.
