o-Phthalaldehyde(OPA), as a disinfectant, has shown wide application prospects in multiple fields. Its efficient, safe, and environmentally friendly characteristics make it the preferred disinfectant in multiple fields such as healthcare, food processing, and household cleaning.
Basic characteristics
Phthalaldehyde is a new chemical disinfectant developed in the United States in the 1990s, which has been certified by the US FDA and designed specifically for high-level disinfection of endoscopes. In recent years, China has also begun to research and approve it as a high-level disinfectant, widely used in the disinfection and treatment of endoscopes and some medical devices. Since 2012, relevant national standards and specifications have gradually incorporated it.
The disinfection effect of phthalaldehyde is achieved by cross-linking and binding with bacterial cell walls or membranes, forming a barrier that interferes with bacterial substance exchange function, preventing bacteria from maintaining normal physiological activities and ultimately leading to cell apoptosis. This unique disinfection mechanism endows phthalaldehyde with efficient and selective disinfection characteristics, which can effectively kill various microorganisms and reduce potential harm to the environment and human health.
