'alkaliser' originates from 'Arabic', specifically the word 'al-qalī', where 'al-' meant 'the' and 'qalī' meant 'ashes of saltwort'.

'al-qalī' transformed into the French word 'alcali', and eventually became the modern English word 'alkali', from which 'alkaliser' is derived.

Initially, it meant 'ashes of saltwort', but over time it evolved into its current meaning of 'a substance that increases alkalinity'.
