It does work
It contains sodium sesquicarbonate which is a precipitation water softener. It reacts with dissolved calcium and magnesium salts precipitating the calcium and magnesium as insoluble carbonates. Thereby preventing the formation of hardness scale and soap scum and allowing soap to lather freely. Transferring to an air tight container will prevent the powder caking.
