protective action

in colloid chemistry
Addition of small amounts of @[email protected] @[email protected] to a hydrophobic @[email protected] may make the latter more sensitive to @[email protected] by electrolyte. Higher concentrations of the same @[email protected] @[email protected] usually protect the hydrophobic @[email protected] from @[email protected] This phenomenon is called protective action.
