Abstract

A peroxide-containing cleaning composition with enhanced peroxide stability includes a peroxide-containing bleaching agent, at least one surfactant, an alkali metal salt in amounts sufficient to maintain an alkaline pH, a silane quaternary ammonium compound present in an amount sufficient to enhance the stability of the peroxide-containing bleaching agent, and an aqueous diluent. A method of stabilizing a peroxide-containing cleaning composition is also disclosed.

Claims

1. A peroxide-containing cleaning composition, comprising:

hydrogen peroxide in the amount of about 0.2 wt. % to 6 wt. % based on the total weight of the composition;

an alkali metal salt in amounts sufficient to maintain a pH of between 8 and 10 wherein said alkali metal salt is selected from the group consisting of sodium bicarbonate, potassium bicarbonate, and combinations thereof;

a combination consisting essentially of a nonionic surfactant which is a C₁₂-C₁₅ ethoxylated fatty alcohol in an amount of about 3.0 to 7.5 wt. % of said composition;

an amphoteric surfactant selected from the group consisting of Lauryl amine oxide, Decyl amine oxide, and combinations thereof in an amount of about 3.0 to 7.5 wt. % of said composition; and

an anionic surfactant which is an alkyl ethoxy sulfate in an amount of about 3.0 to 7.5 wt. % of said composition;

a silane quaternary ammonium compound which is octadecylaminodimethyltrimethoxysilylpropvl ammonium chloride in an amount of about 0.1 to 5.0 wt. % of said composition, said combination enhances the stability of said hydrogen peroxide; and

an aqueous diluent, wherein the total amount of surfactants in the peroxide-containing cleaning composition is up to about 15 wt. % based on the total weight of the composition.

2. The composition of claim 1 wherein the amount of the alkali metal salt is up to about 10 wt % based on the total weight of the composition.

3. The composition of claim 2 wherein the amount of the alkali metal salt is in the range of from about 0.1 wt % to 2.5 wt % based on the total weight of the composition.

4. The composition of claim 1, wherein said composition comprises a C1-C4 alcohol as a solvent for the silane quaternary ammonium compound, wherein said solvent is present in an amount of about 10 wt. % to 50 wt. % of the silane quaternary ammonium compound.

5. The composition of claim 4, wherein said C1-C4 alcohol is methanol.
