Description

COMPOSITION FOR CLEANING AND COATING NON-POROUS SURFACES
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims priority to US Patent Application 62/594,488, filed December 4, 2017.
FIELD OF THE INVENTION
[0002] The present invention relates to a surface-cleaning and coating composition for application on non-porous surfaces, in particular, plastics, metals, and varnished wood, containing a friable mineral selected from the group consisting of slate, calcite, talc, baryte, bentonite, agalmatolite, and diatomite, or a combination thereof. The present invention is also a disinfectant. The method of cleaning and coating surfaces by making surfaces hydrophobic using the surface-cleaning compositions is also disclosed.
BACKGROUND
[0003] Surface-cleaning compositions have been known and used in a variety of household and industrial applications. Various external factors like dust and soot particles, moisture and chemicals can cause corrosion and affect the aesthetic appearance and function of non-porous surfaces. The term“non-porous surfaces,” means surfaces such as plastics, metal (painted or not), and varnished wood that can have a smooth appearance, and do not typically absorb water. This in contrast to“porous surfaces,” by which meant surfaces made from paper, cardboard, untreated woods, and textiles such as cotton, nylon fabrics, and polyester fabrics.
[0004] Often surfaces, even non-porous surfaces, can absorb vapors containing acidic particles and particles of naturally occurring elements. This problem is more severe in urban areas where the high levels of soot particles in the atmosphere cause rapid surface discoloration and deterioration and in industries like automotive, aerospace, marine and others where appliances and industrial equipment are regularly exposed to dirt, grease and water.
[0005] Surface cleaning and coating is particularly important on aerodynamic surfaces, such as aircraft skins, in particular wing surfaces, empennage surfaces, propellers, and rotors. Dirt buildup can have a deleterious aerodynamic effect, impacting the airflow over such surfaces.
[0006] Cleaning solutions have been formulated to address both the need for removal of pollutant particles from surface materials and for exclusion of water from the surfaces. There are many products on the market that are used to repel water from the surface materials and thus prevent the deposition of particles. However, the available products typically contain petroleum or petroleum derivatives, which are associated with high cost and negative environmental impact, both in terms of production and use.
[0007] Surface protection is a complementary feature to cleaning. Typical surface protection agents include waxes, oils, and synthetics such as polyurethane. These products are typically presented as polishing agents, glazes, and wax or coating agents.
[0008] Polishing agents are abrasive, and typically include a material such as aluminum oxide in a petroleum distillate. The polish is applied with a cloth and can remove minor surface imperfections such as small scratches and oxidation, leaving a smooth and mirrored surface. Glazes are non-abrasive and typically contain gloss enhancing oils and Kaolin which effectively fills minor surface imperfections. Wax products typically include a drying oil, a resin, and a solvent, which may be a hydrocarbon such as paint thinner. Auto and marine wax products typically include a wax material such as carnauba wax, and a hydrocarbon solvent such as petroleum distallates. Carnauba wax has a melting point of approximately 85°C and is not water soluble.
[0009] Various cleaning compositions are known that employ micronized minerals, for example calcite, bentonite, or talc. See e.g., WO 2016/118096, WO2014/193918, U.S. Patent No.
8252736 US Publication 2012/0138089; Odom I E (1983),“Smectite Clay Minerals: Properties And Uses,” Phil. Trans. Royal Soc. A, 311 , (1517, 14 June 1983) 391-409, XP002594660, DOI: 10.1098/RSTA.1984.0036. However, no prior art employs the blend of minerals provided in this application as a simple aqueous suspension or solution, and none provide a hydrophobic coating as provided by the instant invention. The instant invention was developed to address the need for a cleaning and surface protection product that does not contain soaps, petroleum distillates, and is not abrasive.
SUMMARY OF THE INVENTION
[0010] The present invention provides a composition for cleaning non-porous surfaces, such as metal, finished wood, painted surfaces, plastic, glass and polished stone surfaces, by removing impurities without the use of soaps, petroleum or petroleum derivatives. When applied, the inventive composition provides a hydrophobic coating and leaves no residue. Moreover, the inventive composition is safe, non-toxic, and free from harsh chemicals. In addition, the inventive composition is shown to have disinfectant properties. [0011] In an embodiment, the present invention is an aqueous suspension of a friable mineral selected from the group consisting of slate, calcite, talc, baryte, bentonite, agalmatolite, and diatomite, or a combination thereof. In an embodiment, the friable mineral is a blend comprising slate, calcite, talc, baryte, bentonite, agalmatolite, and diatomite. The mineral is pulverized to nano-size particle sizes, of about 400 nm by a grinding step, followed by sifting through a 400 nm mesh to obtain a mineral or mineral blend of uniform particle size. The resulting nanopowder is hydrated and further ground in the hydrated state to give a pasty mass containing the mineral nanoparticles of a uniform particle size. When appropriately diluted and applied to a surface, the composition effectively solubilizes surface contaminants such as grease, dust, soot, dirt, and grime. The surface contaminants are effectively washed or wiped away. The inventive composition creates a hydrophobic film and dries leaving no residue.
[0012] The inventive cleaning composition may be liquid or in the form of a cream, paste or gel for application to various surfaces. In an embodiment, the inventive composition is applied as a spray, from a hand-held spray bottle or pressurized spray gun.
[0013] A particular advantage of the inventive composition is that it is water based and non volatile. It is safe to persons applying the material and to the environment. This is distinguished from conventional cleaning and coating compositions that typically employ hydrocarbon solvents such as paint thinner.
[0014] The surface-cleaning composition has numerous domestic and industrial applications. In an embodiment, the surface-cleaning composition is useful for cleaning exterior surfaces, for example in transportation vehicles and outdoor equipment, for example, aircraft exteriors, exterior surfaces of ships and boats, surfaces of vehicles such as automobiles, trucks, motorcycles, bicycles, and outdoor equipment such as solar panels and wind turbine blades.
[0015] In an embodiment, the surface-cleaning composition is useful for surfaces of industrial equipment, for example industrial machinery, such as equipment in machine shops, factory equipment, and manufacturing equipment.
[0016] In an embodiment, the surface-cleaning composition is useful for domestic cleaning applications, such as surfaces in homes and offices, including furniture, kitchens, and bathrooms. The inventive compositions are also useful for cleaning interior surfaces in vehicles such as aircraft, ships, boats, automobiles, and trucks.
[0017] When applied on painted surfaces the inventive composition enhances the surface colors and brightness, while the hydrophobic coating feature prevents deposition of contaminants. Repeated application of the inventive product further increases the resistance of the protective coating and improves the surface appearance and texture.
[0018] Surfaces treated with the present invention do not require further treatment with water to wash away residues, which is environmentally beneficial as it preserves water and reduces the amount of waste.

[0026] Baryte is a mineral consisting of barium sulfate (BaS04).
[0027] Bentonite is an absorbent aluminium phyllosilicate clay consisting mostly of
montmorillonite, having the chemical formula (Na,Ca)o.33(AI,Mg)2(Si40io).
[0028] Diatomite is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled. The typical chemical composition of oven-dried diatomaceous earth is 80-90% silica, with 2-4% alumina (attributed mostly to clay minerals) and 0.5-2% iron oxide.
[0029] The surfaces in general that are useful with the instant composition are hard, non-porous surfaces, as opposed to fabric or porous materials, such as cloth upholstery, clothing, pillows and bedding, the like. However, the inventive composition may be useful with relatively non- porous flexible surfaces, such as leather, latex, and rubberized surfaces.
[0030] In an embodiment, the non-porous surface is selected from a metallic, composite, plastic, or finished wood surface. By the term“composite” surface, it is meant surfaces such as, for example, engineered plastics, fiberglass, epoxies, resins, and the like, which may be fabricated with an underlying fiber reinforcement. By the phrase“finished wood,” it is meant painted or varnished, for example with a polyurethane or shellac varnish. The surface may be in an exterior location, and exposed to the elements, or an interior location. By the phrase “exposed to the elements,” it is meant an outdoor surface exposed to weather, including rain, snow, icing, solar UV radiation, and heat or cold from atmospheric conditions. As used herein, the term“exterior surfaces” means a surface exposed to the elements.
[0031] In an embodiment, the non-porous surface is a hard exterior surface, such as the skin and other exterior components of an aircraft, or exterior surfaces of motor vehicles, trains, and the like. This includes other ground vehicles, including automobiles, trucks, motorcycles, bicycles, and the like. Exterior surfaces also useful in this invention include building materials, such as exterior metal surfaces on buildings. [0032] In an embodiment, the surfaces are interior surfaces, such as those found in homes, offices, schools, and other domestic locations. Such surfaces include floors, countertops, bathroom fixtures such as sinks, toilets, showers, bathtubs, and the like.
[0033] The composition of the present invention has a pH between 6.0 and 8.5, a minimum viscosity of about 300 ctsk, and a minimum density of about 0.90g/cm3.
[0034] Without being bound by any theory, the present inventors believe that the interaction of the nano-mineral and water creates an adsorption complex with lipophilic properties that forms a hydrophobic coating when wet and effectively solubilizes ordinary environmental organic contaminants, such as oils, fats, grease and waxes, permitting them to be easily washed away. Significantly, the nano-mineral is not abrasive. Also, contaminants like soot, dust, particulates, and insects can be effectively cleaned off surfaces with the inventive composition.
[0035] The inventive composition may include a fragrance in certain embodiments. The fragrance may serve several purposes. In one embodiment, a fragrance signals to a user that the inventive composition was recently applied. In another embodiment, the fragrance signals to the user the nature of the product being applied (notwithstanding the label on the bottle). In another embodiment, a fragrance signals to the user a functional feature of the inventive composition. For example, a version of this invention intended for domestic may have a pleasant floral fragrance to compliment a soft interior. In another embodiment, the fragrance may impart an industrial odor or a disinfectant odor, that is intended to signal to the user the function for which the invention is being used. For example, odors that imply a cleaning product are well known in the art. If present, a fragrance is generally used in very small quantities, typically about 0.01% (v/v) to about 0.1 % v/v, but the fragrance may be used in as much as 2.0% v/v.
[0036] The optional fragrance constituent may be based on natural and/or synthetic fragrances and most commonly are mixtures or blends of a plurality of such fragrances, optionally in conjunction with a carrier such as an organic solvent or a mixture of organic solvents in which the fragrances are dissolved, suspended or dispersed. Such may be natural fragrances, e.g, natural extracts of plants, fruits, roots, stems, leaves, wood extracts, e.g. terpineols, resins, balsams, animal raw materials, e.g., civet and beaver, as well as typical synthetic perfume compounds which are frequently products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type, e.g., benzyl acetate, linalyl acetate, citral, citronellal, methyl cedryl ketone, eugenol, isoeugenol, geraniol, linalool, and Typically it is preferred to use mixtures of different perfume compounds which, together, produce an agreeable fragrance. Other suitable perfume oils are essential oils of relatively low volatility which are mostly used as aroma components. Examples are sage oil, camomile oil, clove oil, melissa oil, mint oil, cinnamon leaf oil, lime- blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil, labolanum oil and lavendin oil.
[0037] In an embodiment, the inventive composition may include a quaternary ammomium salt, such as cetalkonium chloride or benzalkonium chloride, in amount of about 5% to 20% v/v.
[0038] In an embodiment, the inventive composition is applied to a hard, non-porous surface in need of cleaning, as a thin uniform film, for example with a spray applicator. The composition may then be wiped off without the application of additional water or other solvent. A spray applicator may include handheld spray bottles or pressurized high-volume spraying equipment for spraying industrial equipment, aircraft exterior surfaces, nautical exterior surfaces, or other large areas where a handheld spray bottle is not appropriate.
[0039] The inventive composition can also effectively solubilize and neutralize bacterial and viral particles, and may therefore act as a disinfectant.
[0040] The surface-cleaning composition is safe and non-toxic, and can be used to wash food items intended for human or animal consumption, for example to wash off dust, preservatives, or other food residues. The surface-cleaning composition is also suitable for washing kitchen surfaces that come in contact with food, such as kitchen counters and utensils.
[0041] In an embodiment, the surface-cleaning composition includes:
about 50% to 92% by volume of water;
about 3% to 40% by weight of a friable mineral selected from the group consisting of slate, calcite, talc, baryte, bentonite, agalmatolite, and diatomite, or a combination thereof; and
optionally about 0.01 % to 0.02% by volume, of a fragrance.
[0042] In an embodiment, the friable mineral is a blend of slate, calcite, talc, baryte, bentonite, agalmatolite, and diatomite.
[0043] In an embodiment, the friable mineral is micronized to a particle size of less than 1.0 pm. In an embodiment, the friable mineral has a particle size of about 400 nm. In an embodiment, the friable mineral is sifted through a screen with a mesh size of about 400 nm. In an
embodiment, the friable mineral has a particle size of about 100 nm. [0044] A variety of methods are well known in the art of particle size measurement, in particular dynamic light scattering and laser diffraction methods are commonly used techniques for measuring nanoparticle sizes in the ranges required in this invention. The particle size may be also determined by ISO 9276-6.
[0045] In an embodiment, the composition has the consistency of a gel, or it may have the consistency of a free-flowing liquid. The viscosity can be adjusted by adjusting the amount of water in the composition.
[0046] In an embodiment, the surface-cleaning formulation comprises:
78.00% water, by volume;
21.99% by weight of a friable mineral blend of slate, calcite, talc, baryte, bentonite, agalmatolite, and diatomite, micronized to a particle size of 0.4 pm
0.01 % fragrance, by volume.
[0047] The immediately preceding formulation has a pH Between 6 and 7, and a density of 0.94 to 0.96 g/cm3. In other embodiments, this composition can be diluted with water to give a less viscous composition.
[0048] A surface on which the inventive composition is applied is water repellent and has surface hydrophobicity. On a test surface, this composition provides 90% water repellency as waterproof protection, for example as measured with ISO test 22958 or AATC TM22. On non- porous surfaces, the composition causes water to bead-up, because the hydrophobic treated surface does not adhere to the water.
[0049] In an embodiment, the inventive composition (22% mineral blend) is a sanitizing agent or disinfectant when applied a hard non-porous surface. The product in the above example was tested against 60 carriers each for the organisms listed in the Association of Official Analytical Chemists (AOAC) Use Dilution Test methods 955.14, 955.15 and 964.02. The organisms were Staphylococcus aureus ATCC#6538; Pseudomonas aeruginosa ATCC#15442; and Salmonella enterica ATCC #10708. Three batches of 60 samples (carriers) were tested for each organism. In this test, each carrier is a stainless steel disk inoculated with a test organism, then exposed to the inventive cleaning composition, and then placed on a growth broth for 48 hours. The disks are then evaluated for microbial growth. The results are shown in Table 1.
[0050] Table 1. Disinfectant Efficacy Test
Figure imgf000009_0001
Figure imgf000010_0001
Each organism was tested with three series employed 60 carriers each.
[0051] The inventive composition does not irritate the eyes and had shown no acute dermal or oral toxicity.
[0052] The inventive composition (22% mineral blend) was tested for acute dermal toxicity. The inventive composition was applied once on an area no more than 10% of the body surface of the 10 healthy albino rats (5 males and 5 females), covered with a gauze and tape and remained in contact with the skin of the animal for 24 hours. After this period of exposure, the excess was removed with sterilizing solution. Observations of the condition of the test animals were taken at 30 minutes, 1 , 2, and 4 hours, and daily for 14 days after the removal of the patch.
[0053] No changes were observed to the skin and hair, eyes, mucosal membranes, nervous, respiratory, circulatory systems, autonomic and central nervous systems, and activity of the somatosensory motor and behavior of the test animals. No symptoms or toxic effects such as tremors, convulsions, salivation, diarrhea, lethargy, coma, vomiting, agitation, edema, erythema, weight loss, necrosis, member mutilation, death, apathy or lack of appetite were observed up to 14 days after the removal of the patch.
[0054] The inventive composition (22% mineral blend) was also tested on rats for acute oral toxicity. The inventive composition was applied orally using an appropriate gastric tube in a single dose. The test was performed on 2 groups of 3 female albino rats, using a dosage of 2000 mg/kg. The animals were individually observed after the administration of the test substance, throughout the first 30 minutes, and periodically during the first 24 hours, with special attention given during the first 4 hours, and daily after this for a total of 14 days.
[0055] No changes were observed to the skin and hair, eyes, mucosal membranes, nervous, respiratory, circulatory systems, autonomic and central nervous systems, and activity of the somatosensory motor and behavior. No symptoms or toxic effects such as tremors, convulsions, salivation, diarrhea, lethargy, coma, vomiting, agitation, edema, erythema, weight loss, necrosis, member mutilation, death, apathy or lack of appetite were observed 14 days after the removal of the patch.
[0056] Eye irritability of the inventive composition (22% mineral blend) was tested in 3 healthy rabbits (Oryctolagus cuniculus) according to OECD test 405 for eye irritation/corrosion. In this test, the eyes are first anesthetized, and using a disposable syringe, 0.1 ml of the inventive composition is topically applied to the conjunctival sac of one eye for each rabbit. The test substance was removed (after 24 hours according to the procedure) with a sodium chloride solution 0.9%. Readings took place every 1 , 24, 48, and 72 hours after the application of the test substance. No ocular reaction such as hyperemia, opacity, iritis, secretion, and chemosis, were observed after 72 hours. Therefore, the inventive composition is considered to be nonirritating.
[0057] As used herein, the word“about” means plus or minus 10% of the stated value, or within one standard deviation on particle size measurements.
