Broad-Spectrum Preservatives

Broad-spectrum preservatives cover a 'broad spectrum' of microbes including bacteria, mold, and yeast and offer the best, most effective protection against microbial contamination for the longest period of time. Typical shelf lives are about 9 - 24 months depending on the type of formula, water content, container, and storage. Broad-spectrum preservatives can be used alone or combined with other preservatives to enhance the protection.
