Is Detojet, Low-Foaming Liquid Detergent, compatible with ceramic aluminum oxide and polysulfone?
Detojet solutions are compatible with aluminum oxide ceramics. There is need to be concerned about polysulfone. Alconox, Inc. has some data that indicates that polysulfone reverse osmosis membranes will have the permeability of the membrane reduced by exposure to oxidizing agents such as sodium hypochlorite. Detojet contains sodium hypochlorite. Detojet also has a very high pH and contains potassium hydroxide. A high pH from the potassium hydroxide reduces the oxidizing activity of sodium hyprochlorite, so there is some compatibility between polysulfone reverse osmosis membranes and Detojet, but probably not continuous long term exposure compatibility.
Alconox, Inc. recommends stability testing for a polysulfone cleaning application and intended type of contact to determine if the Detojet is compatible. For single pass initial cleaning, the polysulfone would be fine. For repeated or extended Detojet contact, depending on the intended purpose of the polysulfone, there might be problems.
