Definitions

• the invention relates to the cleaning of hard surfaces, particularly but not exclusively floors.
• compositions for the cleaning of hard surfaces have been extensively discussed in the art. It is desirable that such compositions should have, in addition to the ability to clean effectively, the ability to provide a good shine to the surfaces they have cleaned. However, surface shine is often compromised by residues of the compositions which are left on the surfaces, and which appear as streaks as water evaporation is completed.
• compositions are used without rinsing after cleaning, and when the compositions are formulated as concentrated compositions, which comprise more actives and less water.
• compositions for the cleaning of hard surfaces which clean effectively in concentrated or diluted form, and which leave no or little streaks after the cleaning.
• the invention encompasses the use, in a hard surface cleaning composition, of :
• the invention encompasses the use, in a hard surface cleaning composition, of:
• the invention combines the first two embodiments and thus encompasses the use, in a hard surface cleaning composition, of

• the invention further encompasses processes of cleaning hard surfaces with the compositions, either dilute or neat.
• various components are combined and used in a hard surface cleaning composition with a view to provide shine to the hard surfaces which are cleaned with the compositions.
• hard surfaces typically refers to floors, walls, windows, kitchen and bathroom furniture, appliances and dishes.
• Obtaining a good shine end result is essentially the sum of two factors, namely: a good spreading of the cleaning product on the surface, and no crystallisation while drying. If both are achieved, a streak-free end result is obtained.
• the streaking phenomenon can thus be described as the apparition of visible residues from the cleaning composition, as the water from the composition or the rinse water evaporates. Molecular crystaliinity and aggregation during evaporation cause streaking, thus give a bad shine end result.
• the ability of a composition to provide "shine" to surfaces refers to the composition's ability to leave little or no eye-visible residues on the surfaces, after evaporation of the water.
• the ability of various compositions to provide shine can be evaluated by the human eye, but it is also possible to evaluate the difference by means of a gloss- meter, such as a Sheen ® 155 gloss meter.
• a suitable method to evaluate a composition's ability to leave no or little residues is to first measure the gloss of a given surface, then apply the cleaning composition on the surface, then leave the composition to dry, and finally measure again the gloss of the surface on which the composition has been applied. The smaller the difference, the better the shine.

Addition of alcohol, in the selected ratios, results in a clear shine benefit.

• compositions herein are preferably formulated as aqueous liquids. They can comprise from 1% to 30% by weight of the total composition of actives, i.e. from 99% to 70% water.

• the composition herein is applied neat onto a surface so as to clean the surface, and is optionally but preferably subsequently removed by rinsing with water.
• the compositions is first diluted in water, typically from 40 to 320 times, and it is then applied to the surface to be cleaned. Thereafter, in this second mode, the composition can but does not necessarily have to be rinsed off of the surface.
• the first mode is generally more convenient for heavily soiled surfaces while the second mode is generally more convenient for large and lightly soiled surfaces such as floors.
