What is its function and benefits?
Alkyl ethoxy sulphates (AES) are a surfactant or surface active agent which is a substance that is used to change the surface tension of water to assist cleansing, wetting surfaces, foaming and emulsifying (the suspension of one liquid evenly within another). (Ref: Cleanright). As anionic surfactants, AES are particularly effective at oily soil cleaning and oil/clay soil suspension. (Ref: Cleanright)
How does it work?
As a surfactant, alkyl ethoxy sulphates (AES) give a product, when dissolved in water, the ability to remove dirt from surfaces such as the human skin, textiles, and other solids.
Because they are anionic, AES can react in the wash water with the positively charged water hardness ions (calcium and magnesium), which can lead to partial deactivation. (Ref: Cleanright)
