Definitions

• a further object of the invention is to improve upon commercially-available water insoluble microemulsions for cleaning hard surfaces.
• the present invention relates to neutral cleaning compositions for dispensing at varying rates from about 0.1 oz./gal to about 10 oz./gal.
• the neutral cleaning compositions provide improved cleaning performance in comparison to
• the neutral cleaning compositions, kits and methods according to the invention have many advantages over conventional neutral cleaning compositions.
• the cleaning compositions form stable solutions, have low foaming profiles, beneficially low toxicity levels (e.g. Green Seal compliant) and provide at least equivalent cleaning efficacy in comparison to non-neutral compositions.
• hydrotrope means a material used in a composition to maintain a single phase neat or aqueous composition or solubilisate (liquid solution). Such hydrotrope may also be used in aspects of embodiments and/or embodiments of the present invention. Hydrotropy is a property that relates to the ability of a material to improve the solubility or miscibility of a substance in liquid phases in which the substance tends to be insoluble. Without being limited to a particular theory of the invention, a hydrotrope modifies a formulation to increase the solubility of an insoluble substance or creates micellar or mixed micellar structures resulting in a stable suspension of the insoluble substance.
• weight percent refers to the concentration of a substance as the weight of that substance divided by the total weight of the composition and multiplied by 100. It is understood that, as used here, “percent,” “%,” and the like are intended to be synonymous with “weight percent,” “wt-%,” etc.
• compositions, kits and methods of the present invention may comprise, consist essentially of, or consist of the components/ingredients of the present invention as well as other components/ingredients described herein.
• consisting essentially of means that the methods, systems, apparatuses and compositions may include additional steps, components or ingredients, but only if the additional steps, components or ingredients do not materially alter the basic and novel characteristics of the claimed methods, systems, apparatuses, and
• the neutral cleaning compositions comprise, consist of and/or consist essentially of a combination of water-insoluble surfactants and an anionic hydrotrope having an approximately neutral pH.
• the compositions may optionally include additional functional ingredients.
• the compositions unexpectedly provide clear, water-soluble products providing significant utility for use as hard surface cleaners.
• the clear solutions are suitable for use as a dilutable detergent concentrate or as a ready-to-use product.
• a concentrate refers to a composition that is intended to be further diluted with water to provide a use composition.
• a use composition refers to a composition that can be applied to surfaces to provide detersive activity.
• a use composition can have a solids content of less than about 90 wt-%, whereas the solids content refers to the weight percent of non-water components.
• Particularly suitable water-insoluble surfactants include branched alcohol alkoxylates. Further description of these surfactants is found in U.S. Patent
• the branched alcohol alkoxylate is a
• branched alcohol alkoxylates can be prepared according to U.S. Pat. Nos. 6,906,320, 6,737,553 and 5,977,048, the disclosure of these patents are herein incorporated by reference in their entirety.
• Exemplary branched alcohol alkoxylates include those available under the tradenames Lutensol XP-30 and Lutensol XP-50 (BASF Corporation). In general, Lutensol XP-30 can be considered to have 3 repeating ethoxy groups, and Lutensol XP-50 can be considered to have 5 repeating ethoxy groups.
• the water-insoluble surfactants are included in the neutral cleaning compositions in an amount effective to provide the detersive properties for effective cleaning.
• An effective amount should be considered as an amount that provides a concentrate of the neutral cleaning composition the optional detersive property.
• the water insoluble surfactants are provided in the amounts of from about 1 wt-% to about 60 wt-%, preferably from about 5 wt-% to about 40 wt-%.
• Examples of such a hydrotrope are xylene sulfonic acid, toluene sulfonic acid, naphthalene sulfonic acid, salts of xylene sulfonic acid (e.g., xylene sulfonic acid, sodium salt; xylene sulfonic acid, ammonium salt; xylene sulfonic acid, calcium salt; and/or xylene sulfonic acid, potassium salt; cumene sulfonic acid, sodium salt; and/or cumene sulfonic acid, ammonium salt), salts of toluene sulfonic acid (e.g., toluene sulfonic acid, sodium salt; and/or toluene sulfonic acid, potassium salt), salts of naphthalene sulfonic acid, and the like, or combinations thereof.

• the kit may also include a removal agent for removing a plurality of soils from a treated hard surface.
• the methods may optionally include a rinsing step to remove any excess neutral cleaning composition.
• a rinse step may be used alone or in combination with a further step for removing soils from the hard surface, e.g. applying a water source and/or mechanical force to remove soils.
• a water source and/or mechanical force e.g. applying a water source and/or mechanical force to remove soils.
• non-traditional mechanical force such as compressed air or a vacuum can be utilized to clean the treated hard surface in combination with the neutral cleaning compositions.
• Neutral cleaning compositions according to the invention were formulated to achieve a low foam formulation, and comply with low toxicity requirements (e.g. GS37 Standard and/or Green Seal compliant). The compositions were concentrated at an appropriate level to provide acceptable cleaning at a 0.25 oz/gal dispense rate. The neutral cleaning compositions were compared to various cleaning compositions that are commercially-available.
• Table 3 shows various concentrate formulations according to the invention.
• Table 4 shows the various use solution preparations according to the invention.
• hydrotropes SXS (96%) and Colatrope INC were added to premade concentrate #5 (from Example 2). Concentrates were agitated until a uniform appearance was achieved and then allowed to equilibrate in a 50°C oven for 2 hours. After two hours the samples were removed from the oven and observations of appearance were recorded. Table 6 shows the percentage by wt. of hydrotrope post-added to the concentrated neutral cleaning composition. A passing evaluation was recorded for uniform appearance without separation, cloudy discoloration. A failing evaluation was recorded for any cloudy appearance and/or separation.
• EXAMPLE 6 The neutral cleaning compositions described according to the invention demonstrate hard surface cleaning efficacy for various conditions and markets. Various concentrations of the formulated neutral cleaning compositions were evaluated. Less concentrated formulations may include those dispensed at 0.5 oz/gal and 2.0 oz/gal. A 0.5 oz/gal dispensed formulation was formulated using a one half of a concentrated formulation of Example 5 (0.25 oz/gal dispensed formulation) as shown in Table 12. Additional less concentrated formulations may be employed, including for example a 2.0 oz/gal formulation. TABLE 12
