Biodegradable alkaline disinfectant cleanser

摘要

American Sterilizer Co has been granted US Patent No 7,838,485 B2 for an aqueous, low-foaming alkaline cleaning composition. The biodegradable, phosphate-free composition consists of sodium hydroxide (50% active), no less than two biodegradable nonionic surfactants that are primary or secondary alcohol ethoxylates; a UV-analysable surfactant with sodium xylene sulfonate (40%) content; and a biodegradable agent containing methylglycine diacetic acid and water. The cleaning composition offers disinfecting properties when applied independently without requiring additional sanitizers or disinfecting components, or separate sanitizing or disinfecting steps, while the UV-analysable surfactant allows validation of the cleaning process where this is necessary or desirable.
