BG 29/2021 Pre-Commission Cleaning of Pipework Systems, Amended 6th edition, written by Chris Parsloe and Martin Ronceray, published by BSRIA in partnership with the Closed Systems Control Association (CSCA) in March 2021, defines a surfactant, or surface-active agent as: ‘A soluble compound that reduces the surface tension of liquids, or reduces interfacial tension between two liquids or a liquid and a solid. Commonly used during the de-greasing stage of the clean. Also used to increase the effectiveness of inhibitor formulations (by improving contact) and may themselves be inhibitors.’
