[0001] The present disclosure relates to a multi-purpose cleaning composition. Specifically, the present disclosure relates to a rinse-free cleaning composition comprising cleaning agent, disinfectant, preservative and stabilizer that exhibits excellent cleaning property over different surfaces and can remove a variety of contaminants.

BACKGROUND OF THE INVENTION
[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] A multi-purpose cleaner is a necessity in all households. It is a one stop solution for all household cleaning. These multi-purpose cleaners can be used to clean a host of things for example, glasses, windows, tiles, plastic-ware, metal-ware, walls, slabs etc. Even though the surfaces to be cleaned are indoors, the amount of dust, grime, wax and dirt that the surfaces may attract is not less. Leaving them unattended for a long time may lead to unhygienic conditions that amount to infections or pest infestations for example, by cockroaches. Regular cleaning of these surfaces therefore is a must.
[0004] The largest group of household cleaning products falls under the category of multipurpose cleaners, but these all-in-one cleaning products majorly constitute water in around 75-90% of the total volume. As these products are highly diluted, it consists of a very small amount of surfactant that leads to poor performance. Multi-purpose cleaners must be capable of safe and effective use for a broad variety of surfaces example, glass, plexiglass, plastic, metal, PVC, wood, marble etc. Additionally, they must also have the potential to be anti-microbials that can kill a host of bacteria that are commonly found in the households.
[0005] Recent studies indicate that cleaning agents have increasingly contributed to air pollution owing to the release of volatile organic compounds (VOCs). The volatile solvents from the cleaning agents evaporate and increase the VOC concentration in the surrounding. VOCs in the air can cause eye, nose or throat irritation, respiratory disorders and in extreme cases can also contribute to liver or kidney damage. Further, these VOCs also have the potential to react with other chemicals in the atmosphere to release further harmful chemicals.
[0006] Therefore, there is a need in the art to develop unique compositions that are environmentally safe, work over different surfaces, have disinfecting properties, do not contain any harmful chemicals and are effective cleaners for different types of contaminants.

[0062] The optimum blend of anionic and non-ionic surfactants as cleaning agents results in superior cleaning efficacy of the multipurpose compositions and demonstrates the technical advancement over the known cleaning compositions. The unique combination of anionic and non-ionic surfactants results in optimum wetting and foaming. When the cleaning composition according to the embodiments of the present disclosure is applied to the contaminated surfaces it reduces the surfaces tension to the significant value which tends to remove the contaminant from the surface.
[0063] According to the embodiments of the present disclosure, the multi-purpose cleaning composition exhibits excellent cleaning property over different surfaces selected from but not limited to glass, windows, mirrors, clear plastic, fiberglass, plexi-glass, tiles, gas stove surfaces, chimneys, countertops, floor materials, metals and stainless steel and can remove a variety of contaminants like dirt, dust, general contaminant (tea, curry, sauce etc.), hucker soil and greasy soil. The cleaning efficacy of the multi-purpose cleaning composition is superior in comparison with the existing marketed cleaning compositions.
[0064] The Multipurpose Cleaner according to the present disclosure has Average Cleaning Efficacy around 97% for acrylic sheet, glass, stainless steel and tiles which is 5% to 17% better than the average cleaning efficacy of Lizol All Purpose Cleaner and Colin Glass Cleaner respectively for acrylic sheet, glass, stainless steel and tiles. The results have been described in detail in Example 4.
[0065] The multi-purpose cleaning composition according to the embodiments of the present disclosure exhibits anti-microbial activity against widely known disease causing microorganisms found on the surfaces. The cleaning composition does not comprise any harmful ingredients and does not increase volatile organic compounds in the surrounding.
[0066] In another embodiment of the present disclosure, the cleaning composition is effective against gram positive bacteria, gram negative bacteria, fungal spores and the like. The study results demonstrating the anti-bacterial and anti-fungal activity of the Multipurpose cleaning composition against a variety of different bacteria and fungi have been described in detail in Example 3.
[0067] In an embodiment of the present disclosure, the cleaning composition may be present in the form of liquid, solid or powder, in compressed form. The essence of compressed technology is that the active ingredients, disinfectants and other excipients are compressed or collected together without the solvent as a base or carrier. The concentrate or the solute is specified in a desired formulation so that once dissolved in solvent or water, dissolves completely. The inventive aspect of the compressed technology is the specific composition of the ingredients involved which are completely soluble, stable, disinfectant and efficient at the same time.
[0068] In a preferred embodiment, the cleaning composition is compressed in liquid concentrate form resulting in a ‘Ready-to-Use’ liquid solution.
[0069] In another embodiment of the present disclosure, the cleaning composition, compressed as a liquid concentrate is applied in the form of aerosol or liquid by further diluting it with water.
[0070] The liquid concentrate (10 mL) is diluted with tap water (500 mL) to make a cleaning solution that is sprayed over the surface to be cleaned. The cleaning composition is left for 1-2 minutes on the contaminated surface after which it is wiped off with a clean and dry cloth resulting in a clean surface, free of any contaminants or unwanted impurities. The cleaning composition is rinse-free and does not require the additional use of water for rinsing the surface after cleaning.
[0071] The multipurpose cleaner exists as a compressed composition, thus decreasing the overall use of plastic per person and is relatively cost-effective than the existing products by about 60-70%. The existing cleaning compositions like Lizol All Purpose Cleaner and Colin Glass Cleaner are available as single use plastic bottles, weighing around 45-50 grams, resulting in around 540 - 600 grams of single use plastic per person per year that can be saved by the use of multipurpose cleaner of the present disclosure. The multipurpose cleaner exists as liquid concentrate sachet that can be dissolved in a reusable bottle before use resulting in reduction of the use of multiple single use plastic bottles every month.
[0072] In another embodiment of the present disclosure, the cleaning composition is prepared by a facile process comprising the following steps:
a) Dissolving the preservative and stabilizing agent in hot water;
b) Mixing the anionic surfactant and non-ionic surfactant to form a mixture of cleaning agent;
c) Adding the disinfectant to the cleaning agent to obtain another mixture;
d) Adding the mixture obtained in step a) to the mixture obtained in step c); and
e) Mixing the fragrance and colorant to the mixture to obtain the required cleaning composition.
[0073] In another embodiment, the cleaning composition is in the form of a tablet, preferably effervescent tablet, wherein the tablet further comprises one or more excipient(s) selected from the group comprising of effervescent excipient, binder and dispersant.
[0074] In yet another embodiment, the effervescent excipient is selected from the group comprising of citric acid, sodium carbonate, sodium bicarbonate and the like, the dispersant is selected from the group comprising of sodium starch glycolate and the like, binder is selected from polyvinylpyrrolidone and the like.

The semi-solid viscous liquid represents the compressed form of the multipurpose cleaning composition that can be diluted with water before use.
[0081] Example 3: Anti-microbial activity of the Multipurpose Cleaning Composition
[0082] Anti-bacterial activity of the Multipurpose Cleaner composition: The method used to determine the anti-bacterial activity of the Multipurpose cleaner is based on the American Society for Testing and Materials (ASTM) E2315 "Standard Guide for Assessment of Antimicrobial Activity Using a Time-Kill Procedure" where the inoculation of a standardized liquid culture of the test strain in a dilution series of the tested antibacterial for which the MIC is determined. The first concentration in the dilution series at which no visual growth can be determined is then considered as the MIC. Graph was plotted with respect to Log concentration of the test product and Probit of mortality for calculation of LC99.99 against bacterial strains Staphylococcus aureus (ATCC 6538), Staphylococcus epidermidis (ATCC12228), Escherichia coli (ATCC 8739), Salmonella abony (NCTC6017) and Listeria monocytogenes (ATCC 19111).
[0083] Procedure: The working culture of bacteria was prepared. Stock solution of the test organism was prepared as to obtain a count of at least 5 x 105 cfu per ml by using densitometer. The concentration of Multipurpose cleaner composition taken was 200 mg/ml to 20 mg/ml, prepared in Soybean Casein Digest Medium (SCDM). After preparation of all the tubes, a 100µl of the adjusted culture (approx.105cfu/ml) was added in to each tube and all the tubes were incubated in the plate reader and observed in 30 seconds and 2 minutes. After incubation, all the tubes were observed with the help of spectrophotometer for growth of microorganisms and time required to kill the microorganism. The effectiveness of the antibacterial activity of Multipurpose cleaner composition was recorded in terms of MIC. The concentration at which the growth of test organisms is inhibited was considered as the MIC of composition.
[0084] The antibacterial activity of Multipurpose cleaner composition was calculated in terms of LC99.99 against Staphylococcus aureus (ATCC 6538) Staphylococcus epidermidis (ATCC12228) Escherichia coli (ATCC 8739) Salmonella abony (NCTC6017) and Listeria monocytogenes (ATCC 19111) and resulted in LC99.99 of 200 mg/ml within 30 seconds against all the bacterial strains.
[0085] Anti-Fungal activity of the Multipurpose cleaner composition: Fungal Strain Candida albicans (MTCC 227) and Aspergillus brasilensis (ATCC 16404) were used to evaluate the anti-fungal activity of the Multipurpose cleaner composition.
[0086] Procedure: The working culture of test organism Candida albicans and Aspergillus brasilensis was prepared. Stock solution of the test organism was prepared as to obtain a count of at least 0.5-2.5 x 103 cfu per ml by using densitometer. The concentration of Multipurpose cleaner composition taken was 200mg/ml to 20mg/ml. After preparation of all the tubes, a 100µl of the adjusted culture (approx.103 cfu/ml) was added in to each tube and all the tubes were incubated for in the plate reader and observed in 30 seconds and 2 minutes. After incubation, all the tubes were visually observed for growth of microorganisms. The concentration at which the growth of test organisms is inhibited was considered as the MIC of product. The effectiveness of the antifungal activity of Multipurpose cleaner composition was recorded in terms of MIC. Graph was plotted with respect to Log concentration of the test product and Probit of mortality.
[0087] The antifungal activity of Multipurpose cleaner composition resulted in LC99.99 against the mentioned fungus at 200 mg/mL within 30 seconds.
[0088] Example 4: Cleaning Efficacy of the Multipurpose Cleaning Composition
[0089] The protocol for the cleaning efficacy was designed by referring to standard protocols like American Society for Testing and Materials (ASTM) and literature survey. The experiment design for determining Cleaning efficacy of the multipurpose cleaner can be categorized into six steps: (1) Selection of substrate/test coupons, (2) Preparation of contaminant, (3) Preparation of contaminant test coupon, (4) Multipurpose Cleaner Solution Preparation, (5) Cleaning of contaminated test coupons, and (6) Analytical approach for Cleaning Effectiveness Factor (CEF) and Residual contaminant calculation.
[0090] Selection of substrate/test coupons: Multipurpose cleaner have wide range of application over varieties of surfaces. The contaminant environmental surfaces include surfaces present in homes, hospitals, commercial places, and offices. The selected surfaces for cleaning performance evaluation are glass surfaces, acrylic surfaces, stainless steel surfaces, ceramic tiles, wood surfaces, and MDF surfaces.
[0091] Preparation of contaminant: Contaminants are the undesired substance present over the environmental surfaces. To evaluate performance of multipurpose cleaner, different categories of contaminant were selected. The contaminants used for the study were mud/soil formulation (AAC01), general contaminant formulation (AAC02), and Hucker’s soil formulation (AAC03). These contaminants are coded with differentiable codes. The compositions of contaminants are given below in Tables 1, 2 and 3.

Linseed oil 0.9% 2.25 gm
Pen Ink 2.6% 6.5 gm
Saline Solution 2.7% 6.75 gm

Preparation of contaminant test coupons: The prepared contaminants were applied to the selected hard surface. The procedure for the preparation of contaminant test coupons starts with rinsing each test coupon being prepared for contamination with the solvent to be used in the contamination solution, followed by drying the test coupon in an oven at 70 oC to 90oC for 1 hour and then cooling at room temperature in a desiccator. Each test coupon was weighed until constant weight was achieved, followed by numbering each test coupon with a specific code (contaminant code/cleaner code). The test coupon was then coated with contaminant by using 25mm paintbrush followed by drying in an oven at 70 oC to 90oC for 1 hour and cooling at room temperature in a desiccator. Weight of the test coupon after application of contaminant was recorded prior to the use of multipurpose cleaning composition. A control sample without contaminant on it was also taken for comparison. Along with the prepared multipurpose cleaner, another set of cleaning solution includes products that were commercially available in the market. These products were used to analysis the competitive advantages and help to identify the gap in the product design. The commercially available products used are Lizol All Purpose Cleaner and Colin Glass Cleaner. The third category of the cleaning solvent is water. The water was used to evaluate the cleaning efficacy alone. The amount of contaminant on the test coupon in mg/cm2 was calculated using the below formula:

Wherein C = amount of contaminant in mg/cm2; W1 = weight of clean test coupon; W2 = weight of contaminant test coupon; S = Surface area of test coupon in cm2
[0092] Cleaning of contaminated test coupons: The multipurpose cleaning composition was used to clean the contaminated test coupons. The cleaning process started with cleaning of designate coupons as the control coupon to undergo cleaning without contamination. Measure the mass of all contaminated test coupons. Clean the control and test coupons by cleaning solution, on an average 5-6 sprays of cleaning solvent are used. Clean the control and test coupons by using sponge. Note down the final mass of each control and test coupons after cleaning of contaminants.
[0093] Quantitative approach for performance evaluation: The ability of a specific cleaning agent for removing selected contaminants from coupons was evaluated for calculating cleaning effectiveness factor and residual contaminants. Cleaning was performed using varieties of cleaning compositions. The effectiveness of the cleaning composition is represented as Cleaning Effectiveness Factor (CEF). A control coupon was used to account for any corrosion or material removal effects due to the cleaning solvent. Cleaning effectiveness factor is defined as the fraction of the contaminant removed from an initially contaminated test coupon and determined by gravimetric techniques whereas residual contamination is defining as the absolute mass of the contaminant remaining after the cleaning process and expressed in milligrams per square centimeter of area.
[0094] The process of analysis includes validation of procedure by examining the control coupons to determine whether they lost mass, gained mass or exhibited the same mass. If the change in mass between control coupon after cleaning and control coupon before cleaning is less than the balance error, then the experiment is valid. The cleaning effectiveness factor indicates the fractional contaminant that was removed during cleaning (for example, CEF = 0.9 indicates that 90 % of the contaminant was removed).

Residual Contaminant (RC) in mg/cm2 was calculated by the equation:

[0095] Results: The said invention along with different types of cleaning agents was tested against different types of contaminations and different types of substrates such as glass, acrylic sheet, stainless steel etc and the results are shown in Figures 1, 2 and 3. From the results of Figures 1, 2 and 3, it was concluded that the Multipurpose Cleaner of the present invention demonstrates Average Cleaning Efficacy around 97% for acrylic sheet, glass, stainless steel and tiles which is 5% to 17% better than the average cleaning efficacy of Lizol All Purpose Cleaner and Colin Glass Cleaner respectively for acrylic sheet, glass, stainless steel and tiles.
[0096] The foregoing examples are merely illustrative and are not to be taken as limitations upon the scope of the invention. Various changes and modifications to the disclosed embodiments will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the scope of the invention.
