HCID 8778Lauryl sulfate

Procedure

When sodium lauryl sulfate is used as the surfactant (4), the acid of step (B) is preferably a dilute mineral acid, such as hydrochloric acid. The dilute hydrochloric acid reacts with the sodium lauryl sulfate to give hydrogen lauryl sulfate, which is an active polymerization catalyst for the polydiorganosiloxane oligomer.
