International Classification:

A61L 2/00
A01N 59/08

US Classification:

422292, 422 1, 422 37, 422 40, 424443, 424661

Abstract:

The present invention relates to a disinfecting article, a sealable housing system for disinfecting articles, and a disinfecting composition comprising a hypohalite composition and a surfactant, for cleaning and disinfecting surfaces, with improved stability and extended efficacy for cleaning and disinfecting surfaces with residues such as foods, dirt, microorganisms and many other common contaminates. The disinfecting article is preferably a wipe that is comprised of high denier fibers and stored in a sealable housing system to ensure the stability of the substrate in the hypohalite releasing solution.

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.

Phillip Hernandez - Pleasanton CA, US

International Classification:

C11D017/00

US Classification:

510439000

Abstract:

Cleaning compositions with low surfactant levels, low solvent levels, and high fragrance levels are effective at meeting the cleaning, environmental, residue, and sensory needs of consumers. This is especially true when used with cleaning implements and cleaning wipes.

David Deleeuw - San Ramon CA, US

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.

International Classification:

C11D 3/00

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.

US Classification:

2194461

Abstract:

Most residential fires originated in the kitchen areas and were the results of negligence during cooking. As the least regulated cooking appliance in a kitchen, stove-top burners were often the culprits. Burners were left on without user presence and caused utensil melt down, igniting fire. It is the objective of this invention to minimize such risks. An electric or gas burner can be improved by the installation of an automated fire safety device that first determines whether the burner is being attended to and if not, senses the temperature of the cooking utensil on it and automatically shuts off the flow of electricity or gas to the burner when the temperature of the cooking utensil begins to exceed a predetermined temperature range. A motion detector is integrated into the safety device and serves as the front-end to a temperature sensor switch. The switch is designed to trigger a power shut-off mechanism when high utensil temperature is encountered.
