WebIonic detergents contain a head group which is either positively or negatively charged. For example, the anionic detergent sodium dodecyl sulfate (SDS) carries a negatively charged sulfate group on a linear C12 hydrocarbon chain. SDS is considered as a very strong and biologically harsh surfactant. Is Simple Green non-ionic? WebThe results indicate that the liquid detergents were not affected by the increase of the water hardness (no significant difference); however, the powdered detergents were affected.
