Abstract

Compositions consisting essentially of: ______________________________________ Component Weight % ______________________________________ Formaldehyde 5-20 Glyoxal 0-1.5 Glutaraldehyde 2-13 Quaternary ammonium bactericide 0.5-5 Wetting agent 0-5 Scent 0-5 Dye 0-1 Solvent Remainder ______________________________________ Possess excellent bactericidal efficiency yet possess little tendency, in dilute aqueous solution, to corrode aluminum and its alloys. They are therefore suitable for use as disinfecting agents in closed circuit aircraft type toilets made of aluminum which operate with aqueous flushing liquids.
