Solution Overview

Problem

Current ready-to-use cleaning and disinfectant compositions often cause ocular and dermal irritation and lack broad-spectrum disinfection and cleaning efficacy, particularly against gram-positive bacteria like Staphylococcus aureus, and do not provide effective surface cleaning on various soils.

Innovation Solution

A neutral pH (6-8) combination of hydrogen peroxide, a C1-C6 monohydric alcohol, and surfactants, including non-ionic, anionic, cationic, and amphoteric surfactants, which provides broad antiseptic and cleaning properties, with optional additives for stability and foaming agents, forming a 'hospital strength' disinfectant.
