Definitions

• the invention relates to an improved, reduced streaking/filming dilute cleaning formulation which is to be used in a no-rinse cleaning application, preferably either by a dosing dispenser or in a combined cleaning tool which contains a cleaning head, a handle, a reservoir of the cleaning formulation mounted to said handle and a means for dispensing the cleaning formulation in a suitable direction relative to the cleaning head.
• the improved cleaning formulation surprisingly enhances the hard surfaces to which it is applied by rendering the surfaces free of dirt, yet imparting transparent shine thereto.
• Standard window cleaning formulations may contain essentially nothing more than water, ammonia, a minute amount of surfactant and a coloring agent (typically, a blue dye).
• a coloring agent typically, a blue dye.
• cleaners are not really effective and their advantage appears to be limited to leaving little residue behind.
• Other no-rinse cleaners are much more effective, such as, for example, those which utilize a low residue surfactant, such as cocoamidopropylamine oxide, or an other such surfactant, along with an effective chelant, such as monoethanolamine or ammonium carbamate.
• Other commonly assigned and co-pending applications include U.S. application Serial Nos. 08/869,854 and 08/879,093, both for Reduced Residue Hard Surface Cleaners (whose disclosures are incorporated herein by reference thereto), which disclose combinations of diphenyl oxide disulfonate surfactants, but without polymers, which are useful in glass cleaning applications.
• Glass cleaning unlike floor cleaning, benefits from an up close and personal use of wicking materials, such as paper towels, and doctoring instruments, such as squeegees, or both, which provide for fairly thorough removal of the cleaning product and the soil targeted therewith, since cleaning of glass is usually done in the line of vision.

• the use of this particular glycol ether with IPA results in a transparent formulation, the combination of solvents nicely dispersing the other ingredients into solution. It is preferred to limit the total amount of solvent to no more than 50%, more preferably no more than 25%, and most preferably, no more than 5%, of the cleaner. However, in some of the compositions of this invention, no solvent may be present.
• a preferred range is about 1-5%, and if a mixed solvent system of alkanol/glycol ether is used, the ratio of alkanol to alkylene glycol ether should be about 1 :20 to 20:1, more preferably about 1:10 to 10:1 and most preferably about 1:5 to 5:1.
• ammonia or, in its form in aqueous solution, ammonium hydroxide, NH 4 OH.
• the pH is alkaline, more preferably, between 7 and 14, more preferably, between 8 and 13.
• Other pH adjusting agents such as NaOH, LiOH, KOH (i.e., the alkali metal salts of hydroxides) and the like may be useful.
• adjuncts Small amounts of adjuncts can be added for improving aesthetic or functional qualities of the invention. Also, those materials below are optional and not to be considered to overlap with the already mentioned Actives in 1. above.
• Aesthetic adjuncts include fragrances, such as those available from Givaudan-Rohre, International Flavors and Fragrances, Firmenich, Norda, Bush Boake and Allen, Quest and others, and dyes and colorants which can be solubilized or suspended in the formulation. A wide variety of dyes or colorants can be used to impart an aesthetically and commercially pleasing appearance. Also, advantageously, the fragrance oils do not require a dispersant since the oil phase will act to disperse limited solubility oils.
• the amounts of these aesthetic adjuncts should be in the range of 0-1%, more preferably 0-0.1%.
• functional adjuncts firstly, because the surfactants in liquid systems are sometimes subject to attack from microorganisms, it may be advantageous to add a mildewstat or bacteristat.
• Exemplary mildewstats include Kathon GC, a 5-chloro-2-methyl-4-isothiazolin-3-one, Kathon ICP, a 2- methyl-4-isothiazolin-3-one, and a blend thereof, and Kathon 886, a 5-chloro-2-methyl-4- isothiazolin-3-one, all available from Rohm and Haas Company; Bronopol, a 2-bromo-2- nitropropane 1,3-diol, from Boots Company Ltd.; Proxel CRL, a propyl-p-hydroxybenzoate, from ICI PLC; Nipasol M, an o-phenyl-phenol, Na + salt, from Nipa Laboratories Ltd.; Dowicide A, a l,2-benzoisothiazolin-3-one, from Dow Chemical Co.; and Irgasan DP 200, a 2,4,4'-trichloro-2-hydroxydipheny
• Other desirable solids may include salts (such as NaCl, Na j SO , builders, electrolytes, chelating agents (without limitation, such as alkali metal salts of EDTA, preferably tetrapotassium EDTA; See Robbins et al., U.S. Patent 5,972,876, incorporated herein by reference; or tetraammonium EDTA ; see Mills et al., U.S. Patent 5,814,591 and 6,004,916, incorporated herein by reference) salts, pigments, and the like. These solids, however, should be present in extremely discrete amounts so as not to affect the streaking/filming character of the inventive formulation.
• Foam control agents i.e., Foam Ban MS 575 may be useful for inclusion herein.
• Example I is one preferred formulation herein.
• Example II The formulation of Example II is repeated, but a control without the diphenyloxide disulfonate is used as a control. It is believed that the diphenyloxide disulfonate stabilizes especially the fragrance, which is an oil, and produces a stable microemulsion, resulting in a clear, isotropic appearance.
• the invention and the Control are stressed under differing temperatures:
• Example II a discrete amount (1 ml) of the formulation of Example II was pipetetted onto clean black tiles, allowed to dry and then graded by 10 experienced panelists on a 1 to 10 score (1 most clear, 10 least clear). This was compared against a formulation lacking diphenyloxide disulfonate.
• Example II a discrete amount (1 ml) of the formulation of Example II was pipetetted onto clean black tiles, allowed to dry and then graded by 10 experienced panelists on a 1 to 10 score (1 most clear, 10 least clear). This was compared against a formulation in which the diphenyloxide disulfonate was replaced with sodium lauryl sulfate, which is a typical anionic cleaning surfactant. The diphenyloxide disulfonate demonstrated superior clarity and appearance, indicating lack of residue.
