Antimicrobial compositions including at least one acid and at least one anionic surfactant are provided. In particular, food contact antimicrobial compositions including at least one acid and at least one anionic surfactant provide a no-rinse compositions efficacious against Norovirus, having acceptable use solution pH that do not require use of personal protective equipment (PPE), are surface compatible and do not leave residues on treated surfaces are provided. Methods of cleaning a surface with the compositions are also provided.

Acid/anionic antimicrobial and virucidal compositions and uses thereof

Antimicrobial compositions including at least one acid and at least one anionic surfactant are provided. In particular, food contact antimicrobial compositions including at least one acid and at least one anionic surfactant provide efficacious virucidal activity, including against Norovirus, having acceptable use solution pH that do not require use of personal protective equipment (PPE), are surface compatible and do not leave residues on treated surfaces. Methods of cleaning a surface with the compositions are also provided and may beneficially eliminate the need to rinse the antimicrobial compositions after use.

Solid acid/anionic antimicrobial and virucidal compositions and uses thereof

A method of detecting concentration of dipicolinic acid and terbium chloride in a chemical composition with a fluorometer, wherein the fluorometer comprises an excitation source for emitting electromagnetic radiation at one or more wavelengths, and a detector module for detecting fluorescence emitted by dipicolinic acid, emitting electromagnetic radiation from the excitation source at wavelengths that induce fluorescence in dipicolinic acid-terbium chloride combination present in the chemical composition, detecting the fluorescence emitted by the dipicolinic acid-terbium chloride combination via the detector module, and determining the concentration of dipicolinic acid using predetermined relationship between fluorescence emitted and the concentration of dipicolinic acid-terbium chloride combination.

Handheld fluorometer

A method of fluorometrically detecting the concentration of chemical components in oxidizing formulations is disclosed. In a particular embodiment the detection is of the stabilizing component of picolinic acid, present in such formulations, although any component which fluoresces may be detected. According to the invention sample preparation of the oxidizing formulation includes adding to said sample an excess of reducing agent to bind peracid, and in the case of picolinic acid, adding to said sample an excess of terbium chloride. The sample then is subjected to radiation to induce fluorescence and the concentration of said chemical component is determined by a linear relationship between fluorescence emitted and the concentration of the target chemical.
