Abstract

Compositions are provided that have at least two of three active ingredients. The active ingredients maybe a salt having a cation NC8-C6 alkanoyl-L di-basic amino acid —C1-C4 alkyl ester, a glycerol monoester of a fatty acid and a sugar ester of a fatty acid. The compositions are useful in methods of killing or inhibiting planktonic bacteria or fungi and bacteria or fungi embedded in a biofilm and prevention of biofilm formation on surfaces. The composition may further comprise a hydrogel and a benefit agent such as an antibiotic that can be solubilized by the hydrogel and supplied to the biofilm matrix by the active ingredients of the composition. Devices such as chronic wound coverings coated with the composition are also provided. Methods of preserving products with the composition are also provided.
