Definitions

• This invention pertains to liquid detergent compositions for use in cleaning hard surfaces.
• Such compositions typically contain detergent surfactants, solvents, builders, etc.
• Liquid cleaning compositions have the great advantage that they can be applied to hard surfaces in neat or concentrated form so that a relatively high level of surfactant material and organic solvent is delivered directly to the soil. Moreover, it is a rather more straightforward task to incorporate high concentrations of anionic or nonionic surfactant in a liquid rather than a granular composition. For both these reasons, therefore, liquid cleaning compositions have the potential to provide superior soap scum, grease, and oily soil removal over-powdered cleaning compositions.
• liquid cleaning compositions and especially compositions prepared for cleaning glass, still suffer a number of drawbacks which can limit their consumer acceptability. They have to have good spotting/filming properties. In addition, they can suffer problems of product form, in particular, inhomogeneity, lack of clarity, or inadequate viscosity characteristics, or excessive "solvent" odor for consumer use.

• superior aqueous liquid detergent compositions for cleaning shiny surfaces such as glass contain zwitterionic detergent surfactant (containing both cationic and anionic groups in substantially equivalent proportions so as to be electrically neutral at the pH of use, typically at least about 9.5, preferably at least about 10) and monoethanolamine and/or certain beta-aminoalkanol compounds.
• zwitterionic detergent surfactant containing both cationic and anionic groups in substantially equivalent proportions so as to be electrically neutral at the pH of use, typically at least about 9.5, preferably at least about 10.

• Zwitterionic detergent surfactants contain both a cationic group and an anionic group and are in substantial electrical neutrality where the number of anionic charges and cationic charges on the detergent surfactant molecule are substantially the same.
• Zwitterionic detergents which typically contain both a quaternary ammonium group and an anionic group selected from sulfonate and carboxylate groups are desirable since they maintain their amphoteric character over most of the pH range of interest for cleaning hard surfaces.

It is an advantage of such zwitterionic detergent, e.g., HASB, that compositions containing it can be more readily diluted by consumers since it does not interact with hardness cations as readily as conventional anionic detergent surfactants.
• Such zwitterionic detergents are also extremely effective at very low levels, e.g., below 1%.
• zwitterionic detergent surfactants are set forth at Col. 4 of U.S. Pat. No. 4,287,080, Siklosi. Another detailed listing of suitable zwitterionic detergent surfactants for the detergent compositions herein can be found in U.S. Pat. No. 4,557,853, Collins, issued Dec. 10, 1985.

• These detergent surfactants are available as Miranol® CS, OS, JS, etc.
• the CTFA adopted name for such surfactants is cocoamphohydroxypropyl sulfonate. It is preferred that the compositions be substantially free of alkyl naphthalene sulfonates.
• detergent surfactants useful herein contain a hydrophobic group, typically containing an alkyl group in the C 9 -C 18 range, and, optionally, one or more linking groups such as ether or amido, preferably amido groups.

It is understood that mixtures of various surfactants can be used.
• Monoethanolamine and/or beta-aminoalkanol compounds serve primarily as solvents when the pH is above about 10.0, and especially above about 10.7. They also provide alkaline buffering capacity during use. However, the most unique contribution they make is to improve the spotting/filming properties of hard surface cleaning compositions containing zwitterionic detergent surfactant, whereas they do not provide any substantial improvement in spotting/filming when used with conventional anionic or ethoxylated nonionic detergent surfactants. The reason for the improvement is not known. It is not simply a pH effect, since the improvement is not seen with conventional alkalinity sources. Other similar materials that are solvents do not provide the same benefit and the effect can be different depending upon the other materials present. When perfumes that have a high percentage of terpenes are incorporated, the benefit is greater for the beta-alkanolamines, and they are often preferred, whereas the monoethanolamine is usually preferred.
• Monoethanolamine and/or beta-alkanolamine are used at a level of from 0.05% to 10%, preferably from 0.2% to 5%.

• Preferred beta-aminoalkanols have a primary hydroxy group.
• Suitable beta-aminoalkanols have the formula: wherein each R is selected from the group consisting of hydrogen and alkyl groups containing from one to four carbon atoms and the total of carbon atoms in the compound is from three to six, preferably four.
• the amine group is preferably not attached to a primary carbon atom. More preferably the amine group is attached to a tertiary carbon atom to minimize the reactivity of the amine group.
• Specific preferred beta-aminoalkanols are 2-amino,1-butanol; 2-amino,2-methylpropanol and mixtures thereof.
• the most preferred beta-aminoalkanol is 2-amino,2-methylpropanol since it has the lowest molecular weight of any beta-aminoalkanol which has the amine group attached to a tertiary -carbon atom.
• the beta-aminoalkanols preferably have boiling points below about 175°C. Preferably, the boiling point is within 5°C of 165°C.
• Such beta-aminoalkanols are excellent materials for hard surface cleaning in general and, in the present application, have certain desirable characteristics.
• the beta-aminoalkanols are surprisingly better than, e.g., monoethanolamine for hard surface detergent compositions that contain perfume ingredients like terpenes and similar materials.
• monoethanolamine normally is preferred for its effect in improving the spotting/filming performance of compositions containing zwitterionic detergent surfactant.
• the improvement in spotting/filming of hard surfaces that is achieved by combining the monoethanolamine and/or beta-aminoalkanol was totally unexpected.
• Beta-aminoalkanols provide superior cleaning of hard-to-remove greasy soils and superior product stability, especially under high temperature conditions, when used in hard surface cleaning compositions, especially those containing the zwitterionic detergent surfactants.
• Beta-aminoalkanols and especially the preferred 2-amino-2-methylpropanol, are surprisingly volatile from cleaned surfaces considering their relatively high molecular weights.

• hydrogen bonding parameters are preferably less than about 7.7, more preferably from 2 to 7, and even more preferably from 3 to 6. Solvents with lower numbers become increasingly difficult to solubilize in the compositions and have a greater tendency to cause a haze on glass.

• Cosolvents are typically used at a level of from 1% to 30%, preferably from 2% to 15%, more preferably from 4% to 8%.
• Dilute compositions typically have cosolvents at a level of from 1% to 10%, preferably from 3% to 6%.
