Description

FIELD OF THE INVENTION

The present invention relates to all-purpose, super concentrated liquid detergent compositions. Specifically, it relates to a super concentrated liquid detergent for cleaning dishware. In particular, the invention relates to a novel liquid detergent composition comprising a primary surfactant system, a secondary surfactant system, and water, in which the ratio of a primary surfactant contained in the primary surfactant system to a secondary surfactant contained in the secondary surfactant system, based on the solids content of the detergent composition, is at least 2.7:1.

BACKGROUND OF THE INVENTION

Liquid detergent compositions have been widely used for the washing of dishware, either manually or automatically, for some time. Consumers generally select a liquid detergent composition based on a variety of factors, all weighted differently by the individual consumer. These factors include the liquid detergent composition's cost, its ability to cut grease, its ability to maintain and generate foam or suds, and, when used to manually wash dishware, its mildness when brought in contact with the users skin. Superiority in only one of these factors, however, will generally not be sufficient to provide a commercially acceptable product. For example, a liquid detergent composition that is superior in its ability to cut grease may contain an excessive amount of anionic and nonionic surfactants, which may cause the composition to irritate the skin of the consumer during use. Additionally, a liquid detergent composition that is significantly less expensive that its competitors will generally contain less surfactants, the cleaning component of the detergent composition, and thus reduce the cleaning ability of the liquid detergent.

Therefore, there exists a need to provide a liquid detergent composition that is inexpensive to manufacture, has superior grease cutting ability, provides long-lasting foam or suds, and is mild to the human skin upon contact. To date, no product that has the unique combination of superior cleaning performance, acceptable mildness to the skin, and cost-effectiveness is commercially available.

A search of relevant prior art indicates that the present invention is novel and nonobvious. European Patent No. EP 070,076 discloses a composition comprising a linear alkyl benzene sulfonic acid, linear alkyl benzene sulfonate and alkali metal, alkaline earth metal, amine and ammonium salts thereof (herein referred to as “LAS” surfactants), in combination with an alkyl polyglycoside (herein referred to as “APG” surfactants). However, the ratio of the LAS surfactant to the APG surfactant according to this document does not approach the high primary-to-secondary surfactant ratio of the present invention.

European Patent No. EP 509,608 similarly discloses a light liquid detergent composition comprising an LAS surfactant and an APG surfactant. This document, however, also fails to disclose the high primary-to-secondary surfactant ratio of the present invention.

U.S. Pat. No. 4,919,839, U.S. Pat. No. 5,415,812, and International Publication No. WO 96/22347 disclose, for example, additional compositions containing an LAS surfactant, as well as other primary surfactants according to this invention. International Publication No. WO 96/24655 describes a light duty cleaning composition comprising 10-30% by weight of an alkyl ether sulphate and alkyl sulphate, and at least 1% by weight alcohol ethoxylate, thus also disclosing several of the primary surfactants according to this invention. U.S. Pat. Nos. 5,545,622 and 5,534,500 describe compositions comprising an alkyl polyglycoside. Thus, while the individual components according to the present invention may be individually known, none of the documents disclosing the individual components, however, disclose the high primary-to-secondary surfactant ratio of the present invention.

SUMMARY OF THE INVENTION

The all-purpose super concentrated liquid detergent composition according to the present invention for the first time possess the highly desirable combination of high initial and lasting foaming and emulsifying properties, optimal cost and improved mildness, performance, and stability characteristics, and this unique combination of properties is directly attributable to the detergent compositions recited in the appended claims. An object of the present invention is to provide an all-purpose, super-concentrated, liquid detergent composition that was optimized for cost and performance.

Another object of the present invention is to provide a super concentrated liquid detergent composition that has a cleaning performance that meets or exceeds the performance of other leading brand detergent compositions.

Another object of the present invention is to provide a super concentrated liquid detergent composition that is mild and does not irritate the skin during and after use.

An additional object of the present invention is to provide a super concentrated liquid detergent composition that can be used in manual cleaning operations to clean a variety of dishware, including dishes, cooking utensils, cutlery, tumblers, crockery, pots and pans.

These and additional objects and advantages of the present invention will be apparent from the description, or may be learned by practice of the invention. The objects and advantages of the invention will be realized by the elements and combinations particularly pointed out in the appended claims.

The compositions in Table 1 were formulated and the performance properties of each was evaluated by both the cylinder test method and the pellet test method. In the cylinder test method (TEC-TM-036), the initial foam, emulsification, emulsion stability and foam stability of the compositions was measured. According to the cylinder test, a 10% dilution of each composition was prepared in a 150 mL beaker with tap water (60-100 ppm Hardness). A water bath or sink was filled with 120° F. water. 90 mL of the tap water and 10 mL of its respective 10% product dilution was added to a 500 mL stoppered graduated cylinder, and the cylinders for each composition were labeled. The stoppers for each cylinder was then loosened, and the cylinders were immersed in the water bath (at 120±2° F.) for 10-15 minutes. The cylinders were then removed from the water bath and the stoppers for each cylinder was tightened. Each cylinder was then inverted back and forth 5-10 times. The height of the foam was recorded as the initial foam.

Ten drops of a liquid soil was added to each cylinder. Used shortening was received from a local McDonald's restaurant, was melted and was used as the liquid soil. The cylinders were recapped and inverted 5 to 10 times to observe the emulsification of the composition. Each emulsion was graded based on the following scale:

1=Uniform milky appearance, excellent;

2=Good emulsion;

3=Average emulsion;

4=Poor emulsion;

5=Very poor. Oil not suspended in emulsion.

The cylinders were then shaken another 15 times and the foam height was recorded. The cylinders were then placed back on the bench, and every 2 to 3 minutes, the foam height was recorded.

After the complete breakdown of the foam, foam regeneration was tested by stoppering the cylinders, shaking each cylinder 15 times, and recording the initial height of the regenerated foam.

In the pellet test (TEC-TM-039), the amount of foam a composition can sustain when exposed to an increasing amount of soil was measured. In order to perform this test, pellets were first prepared in the following manner. 25.0 grams of flour (Martha White), 10.0 grams of potato powder (Idaho instant) and 12.5 grams of whole egg powder are mixed thoroughly in a beaker. In a separate beaker, 37.5 grams of Crisco shortening and 15 grams of olive oil (Bertoli extra virgin) are mixed. A tray was covered with wax paper, and a template containing holes 11 mm in diameter×6.5 mm in depth was placed on the tray. The shortening and oil were mixed and melted, and when the mixture's temperature reached 160 to 180° F., the flour, potato and egg powder mixture was added to it. Mixing continued until a uniform a brownish slurry was produced, and this uniform slurry was poured over the holes in the template. The tray was then placed on a level surface in a freezer for 15 to 20 minutes.

The tray was then removed, and the excess hardened slurry was scraped from the template. The pellets were equal in diameter and flush with both the top and the bottom of the template. The pellets were then removed from the template, and placed in the freezer in a beaker covered with plastic wrap until needed for testing. The pellets average weight was 0.64±0.06 grams.

According to the pellet test, a plastic tub, containing the Kitchen Aid mixer, was filled with water to approximately 1½ inches below the edge of the stainless steel bowl of the mixer. An immersion heater and stirrer were attached to the plastic tub, and the temperature of the water in the plastic tub was stabilized at 120±1° F. The stirrer was turned on and its speed adjustment was set to approximately 4.

The needed amount of concentrate to make the required dilution in fluid ounces per gallon was weighed into a 500 mL volumetric flask. The volumetric flask was then filled to the 500 mL mark with 130 ppm hard water. A magnetic bar was then inserted into the volumetric flask, and the dilution was mixed well. The dilution was then transferred to the stainless steel bowl, and the kitchen mixer was operated at the setting “2”. The dilution was stirred at this setting for exactly 5 minutes. The speed of the kitchen mixer was then reduced to “stir” and 2 pellets were immediately added. Two additional pellets were initially added every minute, followed by the addition of a single pellet until a quarter sized break in the foam was first observed. This was the end point of the pellet test. The number of pellets used for each composition was recorded, and the higher the number of pellets used, the better the foaming and emulsification properties of the tested composition.

All of the compositions set forth in Table 1 achieved an excellent emulsion rating, and demonstrated very good foaming properties. Formula #102-75-4, a composition with a weight ratio of primary surfactant to secondary surfactant of 4:1, and an LAS:APG weight ratio of 4:1 possessed the best overall foaming and emulsification properties in Table 1.

The compositions in Tables 2-5 were formulated and the foaming properties of each were evaluated by both the cylinder test method and the pellet test method, described above. The results of these two test methods are set forth in the tables.

The deemulsification properties of compositions in Tables 2-5 were also measured. To make this measurement, the soap and soil mixture from the cylinder test (˜100 ml) was transferred into a clear glass jar and kept stoppered and undisturbed for 2 weeks. The stability of emulsion formed was then followed. The milky emulsion gradually broke down, deemulsifying the mixture. The deemulsification process was rated on a scale of 1 to 5, with a rating of 1 being the most stable emulsion. This rating gives a measure of stability of the emulsion, which in turn is a measure of better performance.

These results demonstrate that the compositions according to the present invention possessed good foaming and emulsification properties. Tables 2-4 demonstrate that the performance of the compositions containing APG was better when a higher primary-to-secondary surfactant ratio was used. The results also demonstrate that improved overall foaming and emulsification properties were achieved in a composition that contained a mixed salt of dodecylbenzene sulfonate. In particular, Formula #102-81-2 and formula #102-81-5, each of which contained a magnesium/sodium mixed salt of dodecylbenzene sulfonate, achieved the best overall foaming performance. See Table 5.

In Tables 6, 7, 8, 9, and 10, the compositions were formulated and the foaming properties of each were evaluated by both the cylinder test method and the pellet test method, described above. The results of these two test methods are set forth in the tables.

Additionally, the grease emulsification was tested. In this test, a number of drops of oil, as set forth in the tables, were added to each composition. The foam height was measured, and each emulsion was graded according to the following scale:

= standard;

=/− slightly worse than standard;

=/+ slightly better than standard;

+ better than standard;

+1 much better than standard;

+2 much much better than standard;

+3 significantly better than standard;

−1 much worse than standard;

−2 much much worse than standard; etc.

The grading, listed in the tables as “(Emulsification rating),” is recited in parenthesis after the recorded foam height values.

Table 6 demonstrates that a composition containing an SME surfactant gave much better performance in emulsification when a lower primary-to-surfactant ratio was used. Table 7 demonstrates that better performance in foam generation, foam stability and emulsification was achieved in an SME surfactant-containing composition in which a lower primary-to-secondary surfactant ratio was employed.

Table 8 shows that a higher primary-to-secondary surfactant ratio in a composition containing an APG surfactant gave better performance in emulsification. This table also shows that a composition comprising ethoxylated alcohol and an alcohol ether sulfate performed better than a composition comprising the alcohol ether sulfate but no ethoxylated alcohol.

Table 9 demonstrates that, in a composition comprising an SME surfactant, a lower primary-to-secondary surfactant ratio resulted in better performance. Additionally, the table demonstrates that a composition comprising ethoxylated alcohol in addition to an ethoxylated alcohol ether sulfate performed better than a composition comprising only an ethoxylated alcohol ether sulfate (see formula number 102-85-4 and formula number 102-85-6).

Tables 11-15 that follow contain various formulations within the scope of the present invention. In these compositions, the concentration and identity of the individual components in the detergent composition were varied in order to produce compositions having different Mg:Na mole ratios, different LAS:APG/SME ratios, different AES:APG/SME ratios, and different primary:secondary surfactant ratios.

The foregoing tables demonstrate the improved foaming and emulsifying properties directly attributed to the compositions of the present invention. Within the scope of the present invention, the results set forth above demonstrate that a detergent composition comprising an alkyl polyglycoside as the secondary surfactant had better foam generation and foam stability than a detergent composition containing an α-sulfomethyl esther secondary surfactant. With respect to a detergent composition comprising an alkyl polyglycoside surfactant, compositions which contain a mixed salt of dodecylbenzene sulfonate perform better than compositions containing a single salt. Additionally, the results demonstrate that performance was better in these compositions when a higher primary-to-secondary surfactant ratio was used.

With respect to detergent compositions comprising the α-sulfomethyl esther secondary surfactant, the results demonstrate that magnesium salts of dodecylbenzene sulfonates perform better than compositions containing mixed salts of dodecylbenzene sulfonate. Additionally, the performance of these compositions containing the SME surfactant was better when a lower ratio of primary-to secondary surfactant was used.
