Abstract
The invention includes a GRAS preservative system including sodium bisulfate and a combination of specific organic acids that act in a synergistic capacity. The preservative further has the benefit of a higher melting point of approximately 110° or higher making it particularly suited for solid wash applications. According to the invention it has surprisingly been found that a combination of sodium bisulfate, sorbic acid, and benzoic acid produced better preservative properties than other organic acid combinations or each acid by itself.
