Additional information

"should read: < -3.1"

The test substance is a sodium salt of an aliphatic sulfuric acid, these salts are dissociated in water. An undissociated form of the test substance of the salt of a sulfuric acid would be the undissociated form of the sulfuric acid, which is not investigated in this study. Therefore only an investigation at pH 7 was performed.
