Abstract
An aqueous hard surface cleaner with improved soil removal is provided and has, as components, the following: (a) either a nonionic or amphoteric surfactant with optionally, a quaternary ammonium surfactant, the total amount of the surfactants being present in a cleaning effective amount; (b) at least one water-soluble or dispersible organic solvent having a vapor pressure of at least 0.001 mm Hg at 25.degree. C., present in a solubilizing--or dispersion--effective amount; (c) Ammonium ethylenediamine-tetraacetate (ammonium EDTA) as a chelating agent, present in an amount effective to enhance soil removal in said cleaner; and (d) the remainder, water.
Claims14
An aqueous hard surface cleaner with improved soil removal comprising:
- (a) either
- (i) a combination of a nonionic surfactant and a quaternary ammonium surfactant or
- (ii) an amphoteric surfactant,
- the total amount of said surfactant being present from about 0.001-10%, wherein said nonionic surfactant is selected from the group consisting of an alkoxylated alkylphenol ether, an alkoxylated alcohol, or a semi-polar nonionic surfactant which itself is selected from the group consisting of mono-long-chain alkyl, di-short-chain trialkyl amine oxides, alkylamidodialkyl amine oxides, phosphine oxides and sulfoxides;
- (b) no more than 50% of at least one water-soluble or dispersible organic solvent having a vapor pressure of at least 0.001 mm Hg at 25.degree. C.;
- (c) 0.01-25% of tetraammonium ethylenediamine - tetraacetate (tetraammonium EDTA) as a chelating agent;
- and
- (d) the remainder, water.
A method for removing a soil from a hard surface, said method comprising applying to said soil a hard surface cleaner which comprises:
- (a) either
- (i) a combination of a nonionic surfactant and a quaternary ammonium surfactant or
- (ii) an amphoteric surfactant, the total amount of said surfactant being present from about 0.001-10%. wherein said nonionic surfactant is selected from the group consisting of an alkoxylated alkylphenol ether. an alkoxylated alcohol, or a semi-polar nonionic surfactant which itself is selected from the group consisting of mono-long-chain alkyl, di-short-chain trialkyl amine oxides. alkylamidodialkyl amine oxides. phosphine oxides and sulfoxides;
- (b) no more than 50% of at least one water-soluble or dispersible organic solvent having a vapor pressure of at least 0.001 mm Hg at 25.degree. C., said at least one organic solvent present in a solubilizing or dispersion--effective amount;
- (c) 0.01-25% of tetraamnmonium ethylenediamine - tetraacetate (tetraammonium EDTA) as a chelating agent and (d) the remainder, water.
A concentrate for an aqueous hard surface cleaner having improved soil removal comprising:
- (a) either
- (i) a combination of a nonionic surfactant and a quaternary ammonium surfactant or
- (ii) an amphoteric surfactant, the total amount of said surfactant being present up to about 25% of said concentrate, wherein said nonionic surfactant is selected from the group consisting of an alkoxylated alkylphenol ether, an alkoxylated alcohol, or a semi-polar nonionic surfactant which itself is selected from the group consisting of mono-long-chain alkyl, di-short-chain trialkyl amine oxides, alkylamidodialkyl amine oxides, phosphine oxides and sulfoxides;
- (b) no more than 50% of at least one water-soluble or dispersible organic solvent having a vapor pressure of at least 0.001 mm Hg at 25.degree. C., said at least one organic solvent present in a solubilizing--or dispersion--effective amount;
- (c) 0.01-25% of tetraammonium ethylenediamine - tetraacetate (tetraammonium EDTA) as a chelating agent;
- and
- (d) the remainder, water.
A method for the rapid removal of a soil from a hard surface comprising contacting the soil with a hard surface cleaner which comprises:
- (a) either
- (i) a combination of a nonionic surfactant and a quaternary ammonium surfactant or
- (ii) an amphoteric surfactant, the total amount of said surfactant being present from about 0.001-10%, wherein said nonionic surfactant is selected from the group consisting of an alkoxylated alkylphenol ether, an alkoxylated alcohol, or a semi-polar nonionic surfactant which itself is selected from the group consisting of mono-long-chain alkyl, di-short-chain trialkyl amine oxides, alkylamidodialkyl amine oxides, phosphine oxides and sulfoxides;
- (b) no more than 50% of at least one water-soluble or dispersible organic solvent having a vapor pressure of at least 0.001 mm Hg at 25.degree. C, said at least one organic solvent present in a solubilizing or dispersion--effective amount;
- (c) 0.01-25% of tetraammonium ethylenediamine - tetraacetate (tetraammonium EDTA) as a chelating agent;
- and
- (d) the remainder, water.
