International Classification:

C11D 1/83
C11D 3/20
C11D 3/44

US Classification:

510235, 510253, 510155, 510238, 510289, 510290, 510295, 510342, 510365, 510371, 510432, 510421, 510426, 510438, 510439

Abstract:

A cleaning composition with a 2-hydroxycarboxylic acid and a nonionic surfactant gives good antimicrobial performance and good filming and streaking performance. The composition can contain a solvent with low water solubility, a volatile solvent that is miscible in water, and additional surfactants. The nonionic surfactant can be food safe. The composition can be impregnated and used on a wipe or other substrate.

International Classification:

C11D 3/20

US Classification:

510235000

Abstract:

A cleaning composition with a 2-hydroxycarboxylic acid and a food safe nonionic surfactant gives good antimicrobial performance with improved filming and streaking performance combined with low residue and high grease cleaning capability for use on and around food contact surfaces. The composition may contain an anionic surfactant to provide improved wetting performances, and may optionally contain a solvent, additional surfactants, and other adjuncts. The food safe nonionic surfactant is preferably food safe or of low toxicological concern for use on animal, human and food contact surfaces. The composition can be used directly, diluted for use or impregnated and used on a wipe or other substrate, and require no rinsing or removal from the surface following application and cleaning.

US Classification:

510504000

Abstract:

Aqueous dilutions of acidic ternary compositions having unusually synergistic antimicrobial activity against and microorganisms are disclosed. The compositions encompass ternary component mixtures of an alpha-hydroxycarboxylic acid, a monohydric water soluble alkanol and an anionic tenside having a Ternary Ratio residing within a defined phase region wherein synergistic antimicrobial activity is observed; whereas mixtures outside of the defined phase region and those lacking any one of the components do not exhibit synergistic activity. Compositions, methods and articles employing the inventive ternary synergistic compositions, and their utility in sanitizing and disinfecting hard surfaces are described.
