Synopsis The use of anodic silver ions as preserving agents in cosmetics was tested by a challenge test in a set of cosmetic dispersions with the addition of known preservative inhibitors or micro‐organism growth‐promoters such as humectants, hydrosoluble collagen and vegetable extracts. Silver's microbicidal efficacy, compared to that of imidazolidinyl urea or methyl p ‐hydroxybenzoate, showed a more efficient activity especially in the presence of proteinaceous material. This agent may represent a good and safe protection for finished products both in manufacture and during use.
