Claims8
A hard surface cleaning composition, consisting essentially of:
- a) from about 1% to about 60% of an amine oxide detergent surfactant having the formula R.sup.1 R.sup.2 R.sup.3 NO, wherein R.sup.1 has from about 8 to about 30 carbon atoms, and R.sup.2 and R.sup.3 each individually has from about 1 to about 18 carbon atoms,
- b) an aqueous carrier liquid;
- c) a protonated amine;
- and
- a suds suppressor;
- and
- wherein the protonated amine has a pK.sub.a of about 1.5 units above the pH of the composition and the molar ratio of protonated amine to amine oxide is at least 0.1:1.
