A Chemistry With History
From Nineteenth-Century Discovery
To Modern Household Cleaning.
Hypochlorous acid was identified in 1834 while scientists were studying chlorine chemistry in water. Later advances in electrochemical production, concentration control, stabilization, packaging, and storage made consistent ready-to-use HOCl solutions practical for modern applications.
