Definitions

• the invention relates to a hard surface cleaning composition which provides at the same time good cleaning performance and good shine.
• the compositions of the invention are especially suitable for use as a spray cleaning composition.
• Hard surface cleaning compositions are well known in the art and their cleaning performances have been well improved over the years. While focusing on cleaning performances, a new problem has been encountered in that good shine results were not obtained with these compositions, unless the surface which had been cleaned had also been rinsed afterwards, i.e., that good shine performance was incompatible with good cleaning performance, in a non rinse-type hard surface cleaner. Indeed, when used, most compositions leave streaking traces and/or a residual film on the cleaned surfaces which, as a consequence, do not have a good appearance.
• Such problem is particularly a nuisance when the hard surface cleaner is used to clean windows or mirrors, because the residual film is even more apparent.
• compositions have been formulated which yield "volatile” cleaners, which deal efficiently with this problem; such compositions, however, may not be used to clean all surfaces because they often contain solvents which tend to dissolve some materials. Additionally, these compositions have other negatives such as inflammability and noxious odor.
• US 3,591,510 discloses hard surface cleaners which contain surfactants possibly in the form of their ammonium salt, a solvent mixture, and a water soluble builder.
• GB 2 160 887 discloses a composition containing an anionic surfactant, water soluble and water insoluble alcohols and an organic solvent.
• J 62034998 discloses compositions containing an anionic surfactant salt, a water soluble solvent, sodium or potassium hydroxide, and monoethanolamine.
• J 58101198 discloses compositions containing alkanolamine, a mixture of anionic and nonionic surfactant and polypropylene glycol.
• the invention provides hard surface cleaning compositions which have a pH of in the range of from 6 to 11 and which comprise - from 0.04% to 0.6% by weight of the total composition of anionic surfactants ammonium salts, - from 0% to 0.5% by weight of the total composition of ammonia, - from 1% to 9% by weight of the total composition of ethanol, - from 0.5% to 3% by weight of the total composition of n-butoxypropanol, - from 0% to 3% by weight of the total composition of n-propoxypropanol, - from 0.5% to 3% of a primary or secondary monoalcohol having a C5 unsubstituted alkyl branched on linear chain, or mixtures thereof.
• compositions are substantially free of monoethanolamine, diethanolamine, triethanolamine or mixtures thereof.
• compositions of the invention contain anionic surfactants ammonium salts, at a level ranging from 0.04% to 0.6%, preferably from 0.07% to 0.45% by weight of the total composition.
• anionic surfactants for use herein include alkyl benzene sulfonates or sulfates, paraffin sulfonates, olefin sulfonates, sulfonates of fatty acids and of fatty acid esters and the like which are well known in the detergency art. Also suitable are ethoxylated species such as alkyl polyethoxy sulfates and sulfosuccinates.
• Preferred surfactants for use herein are C8-C18 alkyl benzene sulfonates and C8-C18 alkyl polyethoxy sulfates.
• Most preferred for the working of the invention is a mixture of C8-C18 linear alkyl benzene sulphonate and a 3 times ethoxylated C8-C18 alkyl sulfate.
• anionic surfactants are present in the composition in the form of their ammonium salts.
• compositions of the invention also further contain a specific solvent mixture which consists of from 1% to 9% by weight of the total composition, preferably from 8% to 9%, of ethanol, from 0.5% to 3% by weight of the total composition, preferably from 1.5% to 2%, of n-butoxypropanol, and from 0.5% to 3% by weight of the total composition, preferably from 1.5% to 2%, of a primary or secondary monoalcohol having a C5 alkyl unsubstituted linear or branched chain, or mixtures thereof.

• composition of the invention preferably contains ammonia, in amounts up to 0.5% by weight of the total composition.
• compositions of the invention have a pH which is in the range of from 9 to 11 (if the composition contains ammonia), or in the range of from 6 to 9 (if the compositions are free of ammonia).
• compositions of the invention are substantially free of monoethanolamine, diethanolamine, triethanolamine and mixtures thereof.
• compositions of the invention may additionally contain very low amounts, specifically below 0.2%, of builders such as nitrilotriacetates, polycarboxylates, nitrates, water soluble phosphates, silicates, ethylene diamine tetraacetate (EDTA), amino polyphosphonates, phospates and mixtures thereof.

• compositions of the invention are obtained by mixing all the ingredients together; the hard surface cleaners thus obtained are suitable for use in any dispensing means currently used in this technological field, but preferably, they will be used as spray cleaners. These compositions are suitable for use on all surfaces, especially on windows or any glass material.

• KD soil is composed of 25% HSW R soil with carbon black (2), 37.5% Crisco R (1) oil, 37.5% Puritan R (1) oil. This soil is rolled onto stainless steel plates (beforehand cleaned with a detergent and then with alcohol) using a paint roller. A very thin uniform layer is needed since the soil is difficult to cure. The plates are placed in the oven at 115°C ("soft soil”) or 170°C ("hard soil”) for 2 hours and then allowed to age at least 1 day.
