Abstract

The invention is a chemically and physically stable solution of levulinic acid, benzoic acid, and sorbic acids or their salts which is antimicrobially effective against bacteria and fungi. The solution provides improved antibacterial protection for personal care and cosmetic products at lower than expected levulinic acid levels and at desirable use levels. The composition may also include a solvent selected from the group of aromatic alcohols consisting of phenoxyethanol, phenylpropanol, phenylethanol, benzyl alcohol, and mixtures of these alcohols. These solvents extend the range of acidity over which the invention is capable of inhibiting bacterial and fungal growth.
