The present invention relates to the preservative composition for antimicrobial preservation of various water-based cosmetic, pharmaceutical, and chemical products. The composition consists of active ingredients selected to be zinc bis-glycinate or its monohydrate and one or more additional active ingredients selected from the group consisting of polyols with linear- or branched-chain aliphatic hydrocarbon skeleton containing 5-18 carbon atoms and 4-8 hydroxyl (OH) groups in the molecule, e.g., 5-hydroxymethyl-1,5,6,7,11-undecane-pentol, as well as 3,6-di(substituted)piperazine-2,5-diones, e.g., 3,6-di(2-hydroxy ethyl)piperazine-2,5-dione, and optionally, one or more excipients. The excipients are selected from the following group: liquid diluents, suspending agents, wetting agents, pH adjusting agents, solid diluents, and anti-caking agents.
