The present invention relates generally to cleaning compositions and, more particularly, to cleaning compositions comprising fermented fruit solutions, methods for making the same, and methods for using the same.
Cleaning products are commonly used in day to day life, whether it be to clean a home, clean clothes, or for industrial purposes. Common cleaning products are used across the world and can include for example, laundry detergents, stain removers, fabric softeners, floor cleaners, bathroom cleaners, dishwashing products, kitchen cleaners, liquid soap, and multi-purpose cleaners. Most common cleaning products use a relatively toxic (to either health and/or to the environment) mix of chemicals as many such products contain certain ingredients derived from petrochemicals. Products derived from petrochemicals may be harmful since either the final mix of ingredients may contain toxic chemicals and/or the manufacture of these products also may result in the production of harmful by-products.
Natural products are an alternative to toxic petroleum based cleaning products. Examples of natural cleaning products include fermented fruit solutions with other natural based components. Natural products, typically however, do not clean as well as their petroleum based counterparts. Specifically, natural products, historically, are not comparable to leading laundry detergent products and leading laundry stain remover products in terms of cleaning ability. Thus, there is a need for natural based cleaning products with superior cleaning capabilities.
The present invention provides for natural cleaning compositions comprising fermented fruit solutions and builders. The cleaning compositions of the present invention have been shown to be comparable to leading brand name products in terms of cleaning ability after exhaustive testing. Following exhaustive testing, it was determined that the claimed compositions produce products that can be used to launder an article and to clean stains from an article either similar to or better than leading petroleum linked mass market products.

Most preferably, in certain embodiments of the present invention where the surfactant is alkyl polyglycoside, alkyl polyglycoside can be used in an amount of about 5 to about 6.5 weight percent based on the total weight of the composition.
Embodiments of the present invention also include methods of cleaning an article with a cleaning composition comprising a fermented fruit solution and a builder. Following preparation of the cleaning compositions described above, the cleaning compositions can be used to clean an article. Additionally, the cleaning compositions can be used to launder an article or to clean stains from an article. Even more, the cleaning compositions can be used as a surface cleaner. For example, the cleaning compositions of the present invention can be used to clean floors, countertops or other types of surfaces and the like.
The following examples illustrate certain embodiments of the invention without limitation.
Fermented fruit solutions were prepared in accordance with the methods described in detail above. The fermented fruit solutions were prepared similarly except for the composition of the pre-fermented fruit solution. Table 1 provides the components of Examples 1-3:
All concentrations are weight percent, based on the total weight of the pre-fermented fruit composition.
After preparation of the fermented fruit solutions, the pH, total sugar content and total acid content was measured after 2.5 months. Three different samples of each example were measured. The results of these measurements are provided in Table 2.
As is illustrated in Table 2, the total acid content of Example 1 was surprisingly higher than the total acid content of the other examples. Thus, it appears that the weight percents of sucrose, pineapple and water, as used in Example 1 of the present invention result in superior cleaning compositions. Specifically, a ratio of sugar:fruit:water of 1:3:4 appears to produce superior cleaning compositions.
Additional fermented fruit solutions were prepared in accordance with the methods described in detail above. In Examples 4-33, the pre-fermented fruit solutions were all prepared using a sugar:fruit:water ratio of 1:3:4. In Examples 4-18, the initial brix level of the pineapple used to prepare the pineapple puree was not measured. Rather, all pineapples, regardless of brix level were used for Examples 4-18. In Examples 19-33, the selected pineapples included a brix level of greater than or equal to 12%.
The initial brix level of the pre-fermented fruit solution was measured at day 0. After preparation of the fermented fruit solutions, the pH, total sugar content (“TS”) and total acid content (“TA”) of the fermented fruit solutions were measured after 1.5 months. Additionally, the pH and total acid content (“TA”) of the fermented fruit solutions were measured after 2 months. Finally, the pH, total acid content (“TA”), electric conductivity (“EC”) and temperature of the fermented fruit solutions were measured after 3 months. The results of these measurements are provided in Table 3.
As is illustrated in Table 3, the total acid content of Examples 19-33 was surprisingly higher than the total acid content of the other examples. In Examples 4-18, the total acid content after 3 months ranged from 3.06% to 4.23% with a mean value of 3.50%. In Examples 19-33, the total acid content after 3 months ranged from 3.69% to 5.67% with a mean value of 4.77%. Thus, the selection of pineapples for the fruit puree with a brix level greater than or equal to 12% results in superior cleaning compositions.
Additional fermented fruit solutions were prepared in accordance with the methods described in detail above. In Examples 34-48, the selected pineapples were washed only with tap water. In Examples 49-63, the selected pineapples were all washed with previously created fermented fruit solutions.
After preparation of the fermented fruit solutions, the pH and brix level were measured at day 0. Additionally, the pH and total acid content (“TA”) were measured after 2 days. The pH, total sugar content (“TS”), total acid content (“TA”), and electrical conductivity (“EC”) were measured after 1 month. The results of these measurements are provided in Table 4.
As is illustrated in Table 4, the total acid content of Examples 49-63 was surprisingly higher than the total acid content of the other examples. In Examples 34-48, the total acid content after 1 month ranged from 2.70% to 4.50% with a mean value of 3.36%. In Examples 49-63, the total acid content after 1 month ranged from 4.14% to 5.40% with a mean value of 4.88%. Thus, cleaning the selected pineapples with a previously created fermented fruit solution rather than cleaning the selected pineapples with water results in superior cleaning compositions.
The present invention also provides for cleaning compositions comprising fermented fruit solutions and builders. The cleaning compositions of the present invention have cleaning capabilities that are similar to or better than petroleum based products. A significant number of tests were conducted to determine the capabilities of the present invention to launder an article and to clean a stain from an article. The compositions of the present invention clean on par with or better than leading petroleum linked mass market products.
In certain tests, cleaning compositions of the present invention were compared against leading brand name laundry detergent products. Additionally, cleaning compositions of the present invention were compared against leading stain remover products.
In the below described tests (represented in Tables 5-18), the following study methodology was used. In all experiments, stains were created on white cotton pieces (each 10×10 cm), which were attached to a white cotton towel. The stains were all created at the same time in an effort to create consistent stains for each test product. In the experiment with results depicted in Table 5 below, four stains were examined. The four stains examined were: (1) blood; (2) ground soil; (3) carbon with palm oil; and (4) clay with pig fat (this stain was used to approximate sweat with mixed dust/pollution in the air). In the experiments with results depicted in Tables 6-16, ten stains were examined. The ten stains examined were: (1) blood; (2) grass; (3) dark ground soil; (4) coffee; (5) soy sauce; (6) carbon with palm oil (this stain was used to approximate cooking oil stains); (7) clay with pig fat (this stain was used to approximate sweat with mixed dust/pollution in the air); (8) clay with water (this stain was used to approximate dust/pollution in the air); (9) make-up (this stain was used to approximate a typical stain created by a person wearing make-up); and (10) red wine. In the experiment with results depicted in Table 17, nine stains were examined. The nine stains examined were the same as the previously described ten stains with two exceptions. First, the clay with water stain (i.e., stain (8)) was not used. Second, the clay with pig fat stain (i.e., stain (7)) was replaced with a different stain used to approximate sweat. The new stain was prepared using the following ingredients:
In the experiment with results depicted in Table 18, seven stains were examined. The seven stains examined were the same as the previously described nine stains (including the new stain 7), with two exceptions. The two stains: (i) carbon with palm oil (i.e., stain (6) noted above) and (ii) make-up (i.e., stain (9) noted above) were not used.
After creating the stains, the stained towel was washed with two other white cotton towels using an amount of 35 mL of each test detergent product. Standard washing machines (Brand: Electrolux; model: Time Manager) were used on cotton setting at a spin cycle of 500. A color analyzer (model no. RGB-1002) was used to determine a numerical value representative of each of red, green, and blue color (on the device, red values range from 0 to 1023 (“R”); green values range from 0 to 1023 (“G”); blue values range from 0 to 1023 (“B”)), for each type of stain. The higher the number, the whiter the object is—pure white cloth would have an approximate numerical value of R=1023, G=1023, B=1023. Stains were measured with the color analyzer both before the wash and after the wash; there are three numerical values for each stain (R, G, B). For example, for 10 stains, there are 30 total measurements of the stain before the wash, and 30 total measurements of the stain after the wash. The 30 total measurements of the stain before the wash were added together, and the 30 total measurements of the stain after the wash were added together. The difference between the sum of the measurements after the wash and the sum of the measurements before the wash was calculated and represents the “cleaning value” of the cleaning composition. The larger the difference in numerical values (i.e., the larger the cleaning value), the more the stain had been removed, and the cleaner the cloth. As indicated in the description of each experiment, certain washing experiments were conducted in ambient water temperature (25° C. to 35° C. in Thailand) (setting used on washing machines was the cold cotton setting). Other washing experiments, as indicated, were conducted at warm water temperature settings of 60° C. (setting used on washing machines was the 60° C. cotton setting).
While the absolute numerical values are not necessarily comparable, differences in cleaning values are comparable (note that for each experiment, stains were made at the same time). Thus, cleaning values were the reported results for each study. In addition to determining cleaning values, the results were examined visually. The cleaning values, however, were determined to be more reliable than the visual results.
In one experiment, different compositions containing different surfactants were compared. Six different compositions were examined comprising either 90% of fermented fruit solution or water and 10% of one of three surfactants. In this study, ambient water temperature conditions were used. Additionally, only four stains were examined: (1) blood; (2) ground soil; (3) carbon with palm oil; and (4) clay with pig fat. The results of the study are provided in Table 5.
As indicated by the above table, all three surfactants examined—cocamidopropyl betaine, alkyl polyglycoside, and sodium lauryl sulfate—worked synergistically with fermented fruit solution. In all three instances, the fermented fruit solution in combination with the surfactant produced superior results to water in combination with the surfactant. That is fermented fruit solution in combination with a natural based surfactant produced superior cleaning abilities to water with a natural based surfactant.
Additional embodiments of the present invention were prepared using further additives. In addition to surfactants, additives such as boric acid, sodium citrate, thickeners, sodium polyaspartate, oleic acid, lactic acid, sodium bicarbonate, ethanol, glycerol, citric acid, hydrogen peroxide, essential oil, preservatives, pH adjusting agents, etc. were used.
