Description

The present invention relates broadly to cleaning compositions, particularly laundry or dishwashing detergent compositions, and more specifically to detergent compositions specifically designed for manual / manual or semi-automatic cleaning of fabrics or dishes. Regarding things.

Detergents containing anionic detergency surfactants for cleaning fabrics have been known for many years. Historically, washing laundry has been defined as a process that primarily involves the removal of stains. Following this historic approach to cleaning, laundry detergent designers have focused their efforts on formulating detergents with longer carbon chain surfactants, ensuring maximum surfactant activity and the most. Achieved effective dirt removal.

Such long-chain surfactants can generate large amounts of foam during the washing cycle of the fabric washing process. Therefore, consumers consider high foam volume to be the first and most desirable cleaning signal. For hand-washing consumers, who still make up the majority in most developing countries, high foam volume is especially desirable because consumers can directly feel and touch the foam generated during the hand-washing process. This is because the volume can be intuitively associated with sufficient washing of the fabric.

Paradoxically, a large amount of foam during the wash cycle usually leads to more foam during the subsequent rinse cycle. When consumers observe the foam during the rinse cycle, they immediately think from this foam that surfactant residue may still remain on the fabric. Surfactant residues remaining on the fabric can cause skin irritation and can leave the fabric "sticky" after drying, making it more responsive when worn. Easy to attract a lot of dust. As a result, the consumer will apply the fabric a few more times until the foam has completely or substantially disappeared from the rinse and the fabric is now "clean" and free of surfactant residues. It feels like it needs to be rinsed. However, in many cases, one or two rinses are sufficient to remove most or all of the surfactant residue from the fabric, even though a significant amount of foam remains in the rinse. is there. In other words, no additional rinsing is necessary and excessive. Such excessive rinsing requires additional time, effort, energy and water. Excessive rinsing is especially undesirable in resource-poor areas, especially in areas suffering from water shortages.

Therefore, the foaming properties of the detergent composition during both the washing and rinsing cycles of the fabric washing process are important to the overall consumer washing experience, especially the hand-washing consumer.

Consumers, in particular, wash the laundry completely manually (ie, completely manual / hand wash), or wash the laundry manually (ie, semi-automatically) in combination with mechanical washing. There is a need to provide an improved washing (ie, washing) experience to consumers who are habitual in any of these things. Specifically, this improved washing experience is made possible by the desirable lathering properties defined by at least four key points observed by the consumer (hereinafter referred to as "touch points"). Both of these points suggest to consumers that the laundry has been thoroughly washed and rinsed. The lack of any of these touchpoints can result in consumers having a less than ideal laundry experience.

These four touchpoints are referred to herein as "Flash Suds," "Suds Mileage," "Initial Rinse Suds," and "End Rinse Suds." These are referred to and described below with reference to FIG. 1, which shows a typical washing process with a washing cycle followed by a rinsing cycle.

Before the washing cycle, that is, during the pre-washing process, the consumer dissolves the laundry detergent product in a certain amount of water to form an aqueous washing solution and attempts to bring the laundry to be treated into contact with the washing solution.

The wash cycle is initiated by mechanically stirring the laundry with the wash solution, either in the washing machine or directly by the consumer's hands, thereby the first stage of the wash cycle, i.e. "W-1" shown in FIG. During the stage, it results in an early generation of foam, characterized by a significantly large amount of foam (measured by height), which occurs at a relatively high rate (within the first 2-3 minutes of the wash cycle). The initial generation of this foam, the so-called "flash foam", constitutes the first touch point and indicates that the surfactant in the laundry detergent is functioning effectively and washing the laundry. At the second touch point, the volume or height of the wash foam at a relative level, i.e. the "foam effect", over the second stage (the "W-2" stage shown in FIG. 1), which is the continuation of the wash cycle. Needs to be maintained or sustained.

These two touch points indicate to the consumer that the laundry detergent is effective in washing the laundry and is maintained throughout the washing cycle. In the W-1 stage, if there is no flash foam or the flash foam volume is not large enough, consumers may interpret the laundry detergent product as ineffective. If the foam effect is not maintained over most of the W-2 stages of the washing cycle, the consumer is sufficient for the laundry detergent product to lose its cleaning effect or to effectively clean all bundles of laundry. It may be interpreted that the detergent is not in the detergent.

After the wash cycle, before the rinse cycle, i.e. in the intermediate steps, the well-washed laundry is separated from the wash liquor. The cleaning solution is drained or otherwise discarded. The laundry is squeezed or spun to remove excess wash solution, followed by contacting the laundry with clean water or rinse solution. The foam volume (measured by height) during this intermediate step is not measured as it is not important to the consumer and the dotted line is the approximate foam volume (height) during this step for illustration purposes. (Measured by) is shown only.

During the rinsing cycle, mechanical agitation (mechanical or manual) is used to wash in the rinsing solution when attempting to rinse any carry-over or residual surfactant, and dirt from the laundry. It also applies to things. In the first stage of the rinsing cycle, the "R-1" stage of FIG. 1, some initial bubbles may be observed in the rinsing solution, which are referred to as "initial rinse bubbles". A portion of such initial rinse foam, shown in FIG. 1, is carried over from the washing cycle by the laundry, i.e., residual foam adhering to the laundry. The rest of the initial rinse foam is produced by mechanical agitation of the rinse solution due to the presence of carry-over components or residual surfactant. Such initial rinse bubbles constitute a third touch point, which is preferably of medium volume (measured by height). Given the carry-over ingredients of the surfactant from the washed laundry, consumers expect some initial rinse foam. In the absence of any initial rinse foam, consumers may question the effectiveness of previous wash cycles.

At the fourth touch point, rapidly at the second continuation stage of the rinse cycle (“R-2 stage” in FIG. 1) leading to zero or near zero “final rinse foam” volume (measured by height). , And significantly requires the bubbles to disappear (indicated by the dotted arrow). Despite continued agitation, the rinse foam volume (measured by height) decreases significantly and rapidly to zero or near zero levels during this stage. It should be noted that in the R-2 stage, both the magnitude and rate of such foam reduction are important as they both indicate that laundry rinsing is effective. At the end of the R-2 stage, rinse foam is removed or almost removed, suggesting to consumers that most or all residual surfactant has been rinsed from the laundry. The consumer can move on to post-rinse processes (eg, drying and / or ironing the laundry). Therefore, consumers can rest assured that they can stop rinsing and end the washing process, which will help not only save water, but also save consumers time.

Washed laundry if the reduction of rinse foam during the R-2 stage is insufficient or not fast enough to reach the final rinse foam volume (measured by height) at or near zero. Or suggest to the consumer that the residual surfactant still remains in the rinse solution. As a result, the consumer feels that the rinse is not yet complete and unnecessarily further rinses and / or uses additional rinse water until all bubbles are removed or almost eliminated. You may spend time. Therefore, to suggest that the detergent product can be easily rinsed from the washed laundry, i.e. an easy rinse formulation that can provide a significant differentiation of the laundry detergent product. It is important that there are 4 touch points.

A laundry detergent product that provides optimized foaming properties at all four touch points described above suggests not only the high cleaning effect of the laundry detergent product, but also the advantage of easy rinsing. It can also help consumers save water and / or reduce the time it takes for users to rinse the laundry. Traditional laundry detergents can provide a washing experience at one or more of these touchpoints, but provide consumers with optimized foaming properties at all four touchpoints (while cleaning effect). There has never been a product (also offered).

Therefore, such laundry detergent products are needed.

Foam-Optimized Surfactant Systems The inventors of the present invention have prepared one or more branched non-alkoxylated C _6- C ₁₄ alkyl sulfate (BAS) surfactants in specific amounts and specific weight ratios. A cleaning composition containing one or more linear, non-alkenylated C _{6 to} C ₁₈ alkyl sulfate (MCAS) surfactants in the combination of the combination of is a special foaming of the cleaning composition. Found to show surprising and unexpected improvements. Improved foaming properties are large "flash foam" volume at W-1 stage and good "foam effect" at W-2 stage in the wash cycle, moderate at R-1 stage in the rinse cycle. At the R-2 stage in the amount of "early rinse foam" and rinse cycle, the rinse foam is dramatically reduced and eliminated, and the "final rinse foam" is zero or nearly zero.

Such unique lathering properties provide hand-washing consumers with a comfortable washing and rinsing experience, especially during the rinsing stage. The volume of foam produced and its persistence / stability during the wash cycle are high enough to indicate to the consumer that effective washing is taking place. A moderate amount of foam is observed early in the rinse cycle. Consumers expect this because after observing a large amount of foam generated during the wash as a sign of effective wash. However, once the rinse cycle begins, the bubbles undergo a dramatic and rapid reduction and disappearance during the first minute or two of the rinse. Consumers, especially hand-washing, dramatically and quickly reduce and eliminate rinse foam, and finally, at the end of the first rinse cycle, the foam is slightly or absent, clear. You will have the opportunity to visually observe that it becomes a rinse solution. By visually recognizing that the foam has diminished and disappeared, the article to be cleaned has undergone effective cleaning and has been thoroughly rinsed, and now there are no stains or residual surfactant left. Show that clearly. Therefore, the consumer will rest assured to stop the washing process after the first rinse cycle. Therefore, the need for further rinsing is eliminated, and in some cases the concept of a single rinse becomes possible.

The surprising and unexpected foaming properties achieved by the cleaning compositions of the present invention are specifically the initial large cleaning foam volume, large foam effect and measured by using the foaming property test described below. It features a fast reduction rate of rinse foam. Specifically, the unique foaming characteristics are defined by the following. That is, a) initial cleaning foam volume of about 30 cm or more (measured by height), b) foam effect of about 20 cm or more (measured by height) and c) measured by using the foaming characteristic test described later. The rate of decrease of rinse foam is about 40% / min or more. The initial wash foam volume evaluates the first touch point. That is, the "flash foam" described above during the W-1 stage of the wash cycle. The foam effect evaluates the second touch point described above (hence, named after it) during the W-2 stage of the wash cycle. The rate of decrease of the rinse foam is the same as the above-mentioned "initial rinse foam" and "final rinse foam" between the third and fourth touch points, that is, the R-1 and R-2 stages in the rinse cycle. evaluate.

The initial wash foam volume can be as high as about 50 cm and may range from about 30 cm to about 50 cm. Preferably, the initial cleaning foam volume of the cleaning composition is about 32 cm or more, preferably about 35 cm or more, and more preferably about 40 cm or more. More preferably, the initial wash foam volume is in the range of about 30 cm to about 40 cm, preferably about 32 cm to about 38 cm and more preferably about 33 cm to about 37 cm.

The foam effect also has an upper limit of about 50 cm and may be in the range of about 20 cm to about 50 cm. Preferably, the foaming effect of the cleaning composition is about 22 cm or more, preferably about 25 cm or more and more preferably about 30 cm or more. More preferably, the foam effect is in the range of about 20 cm to about 40 cm, preferably about 22 cm to about 35 cm and more preferably about 25 cm to about 33 cm.

The retention of wash foam is calculated from the initial foam volume and foam effect and may range from 60% to 120%. Preferably, it is 65% or more, or 70% or more or 75% or more. More preferably, the wash foam retention rate is in the range of about 70% to about 100%, even more preferably about 75% to about 100% or about 80% to about 100%, and most preferably about 90% to 100%. ..

The rate of decrease of rinse foam is preferably in the range of about 40% / min to 100% / min. Preferably, it is in the range of about 50% / min to 100% / min. More preferably, it is in the range of about 60% / min to 100% / min. Even more preferably, it is in the range of about 70% / min to 100% / min. Even more preferably, it is in the range of about 80% / min to 100% / min. Most preferably, the washing composition of the present invention has a rinsing foam reduction rate of 100% / min. This means that within 1 minute of the start of the rinse cycle, all bubbles in the rinse solution disappear, resulting in a "zero foam" rinse solution. This is because there is a rapid rinse reduction in front of the consumer, but the rinse solution now is clear and sends a strong visual signal to the consumer that the rinse may be stopped. The most wonderful thing.

Such improved foaming properties described above include one or more branched dealkoxylated C _{6 to} C ₁₄ alkyl sulfate (BAS) surfactants and one or more linear dealkoxylated C ₆ to C. It can be achieved in combination with ₁₈ alkyl sulfate (MCAS) surfactants. When combined together, these two surfactants interact to drive wash foam stability and at the same time maintain a rapid reduction in rinse foam during the first minute of the rinse cycle (measurement). (Indicated by the rate of rinse foam reduction) is found. This achieves the improved and desirable foaming properties described above.

Branched non-alkoxylated C _{6 to} C ₁₄ alkyl sulfates (BAS)
Alkoxylation can adversely affect the rate of rinsing foam reduction of the resulting cleaning composition, even at relatively low levels (eg, a weight average of about 1), and thus the BAS surfactant of the present invention is non-existent. It is important that it is alkoxylated. Therefore, it is rather desirable to use a non-alkoxylated alkyl sulfate surfactant.

Branching of the C _{6 to} C ₁₄ alkyl chains in the BAS surfactant is also important because linear alkyl sulfates have poor foam stability during the wash cycle, which in turn results in significantly less foam effect. is there. Therefore, it is rather desirable to use a branched alkyl sulfate surfactant.

In addition, the BAS surfactants of the present invention are characterized by relatively short alkyl chains (ie, having about 6 to about 14 carbon atoms). Lucil sulfate surfactants with longer alkyl chains can result in significantly slower rinse foam reduction rates in the resulting cleaning composition. Therefore, it is desirable to use BAS surfactants with relatively short alkyl chains (ie, C _{6 to} C ₁₄ ), preferably those branched alkyl moieties have a weight average carbon number of about 9 to about 14, more preferably. Is characterized in the range of about 10 to about 13, and most preferably about 11 to about 13.

Further preferred neutralizers for anionic surfactants in the acid form include ammonia, amines, or alkanolamines. Non-limiting examples of alkanolamines include monoethanolamine, diethanolamine, triethanolamine and other linear or branched alkanolamines known in the art. Suitable alkanolamines include 2-amino-1-propanol, 1-aminopropanol, monoisopropanolamine or 1-amino-3-propanol. Amine neutralization may be carried out completely or partially, for example, some of the anionic surfactant mixture may be neutralized with sodium or potassium, and some of the anionic surfactant mixture may be amine. Alternatively, it may be neutralized with an alkanolamine.

In a non-essential, but preferred embodiment of the invention, the BAS surfactant has the general formula (I).

式中、Ｍはアルカリ金属、アルカリ土類金属、アンモニウム、アミン又はアルカノールアミンのカチオンであり、ｘ及びｙは０〜約１０の範囲の整数から独立して選択され、ｚは約１〜約４の範囲の整数であり、ｘ＋ｙの和はｚ以上であり、及びｘ＋ｙ＋ｚの和は約３〜約１１の範囲である。好ましくはｚは約１、及びｘ＋ｙの和は約８〜約９である。

Test Method Various techniques for determining the properties of the composition containing the branched AS surfactant and the short chain nonionic AA surfactant of the present invention are known in the art. However, the following assays must be used to fully understand the invention described and claimed herein.

Test 1: Foaming property test (for determining various foaming parameters)
In the present specification, the foaming characteristics of the test detergent composition are measured using a foam cylinder tester (SCT). The SCT has a set of eight cylinders. Each cylinder is a plastic cylinder about 66 cm long, has a uniform inner diameter of 50 mm over its length, and can be covered or sealed with a rubber stopper during rotation. All eight cylinders have the central part of each cylinder mounted on a horizontal axis. All eight cylinders are perpendicular to the horizontal axis but are arranged parallel to each other. The cylinders are evenly spaced between them and rotate together around a horizontal axis at a speed of 20 to 22 revolutions per minute (rpm) along a vertical plane perpendicular to the horizontal axis. be able to.

The following factors can affect the measurement results and should be carefully controlled. That is, (a) the concentration of the test detergent composition in the cleaning liquid and the rinsing liquid, (b) the hardness of the water used to form the cleaning and rinsing liquid, (c) the water temperature, and (d) the rotation speed of the SCT cylinder. And the number of revolutions, (e) the type of dirt used and the amount of dirt used in cleaning, and (f) the cleanliness inside the SCT cylinder.

Follow the steps below to achieve foam measurements for each test detergent composition.
1.1.5 g of the test detergent composition (either in granules or liquid form) is weighed and at room temperature its hardness is about 0.27 g / L (about 16 gpg) (Ca / Mg 4: 1 and 21 It is dissolved in 300 mL of reverse osmosis (RO) water (formed by mixing 9.9 mg / L CaCl2.2H2O and 111.3 mg / L MgCl2.6H2O).
2. The mixture is stirred for at least 15 minutes to form a cleaning solution sample containing the test detergent composition at 5000 ppm.
3. 3. Pour the test solution into the SCT cylinder and close it tightly using a rubber stopper to secure the cylinder in place and prepare for rotation. To perform foam measurements of different test detergent compositions at the same time, other SCT cylinders can be filled with sample solutions formed by using other test detergent compositions.
4. Power on the SCT and rotate the cylinder 10 times at a speed of 22 rpm.
5. The rotation by the SCT is stopped, and the SCT cylinder is fixed in the upright position.
6. Wait 1 minute before recording the foam volume (represented by absolute foam height) in each SCT. This is taken as the foam volume produced by the test detergent composition rotated 10 times. Since all SCT cylinders have the same inner diameter, the foam volume at any given point can simply be expressed in absolute height of foam (centimeters (cm)) within each SCT cylinder, which is the cleaning solution. Alternatively, the height of the rinse solution is measured by subtracting the total height of the foam and the wash solution or rinse solution.
7. The SCT is powered on, the cylinder continues to rotate 20 more times at a speed of 22 rpm, the SCT is stopped, and the foam volume is recorded as the foam volume at 30 revolutions.
8. Step 7 is repeated and the foam volume at 50 and 70 revolutions at a rate of 22 rpm is recorded.
9. Stop the SCT rotation, remove the rubber stopper from the cylinder, and put a piece of fabric with Beijing viscosity (BJ viscosity) and a piece of fabric with dirty cooking oil (DCO) into each SCT cylinder. And place it. The preparation of these fabrics will be described below.
Preparation of fabric with BJ clay attached ● 20 g BJ viscosity (collected from 15 cm below the surface of Beijing, China, dried at room temperature for 1-2 weeks, then blended in a strong blender and sieved 150-200 # (Through) is dispersed in 80 mL of deionized water by stirring to obtain a viscosity suspension. Alternatively, Arizona clay (ie, Arizona Test Dust with a median particle size of about 0.889 micrometers and an average particle size of about 0.942 micrometers, by Power Technology Inc. of the United States) can be used in place of the BJ viscosity.
● While continuing to stir the viscosity suspension, place 2 g of such clay suspension in the center of a piece of 10 cm x 10 cm, CW98 white cotton knitted (100%) fabric (supplied from DaXinFangZHi (Beijing, China)). Apply to form a circular stain with a diameter of about 5 cm.
● Subsequently, the cotton fabric is allowed to stand and dried at room temperature before use.
Preparation of DCO-attached fabric ● Using 100 g of peanut oil, 20 g of salty fish was fried at 150-180 ° C for 2 hours to form DCO.
● 0.6 mL of DCO is dropped onto the center of the 10 cm × 10 cm cotton fabric described above to form a circular stain with a diameter of about 5 cm.
● Cut the cotton fabric into two equal pieces and use one piece for each performance evaluation.
10. Return the rubber stopper to the SCT cylinder.
11. The SCT is powered on, the cylinder continues to rotate 40 more times at a speed of 22 rpm, the SCT is stopped, and the foam volume is recorded as the foam volume at 110 revolutions.
12. Steps 9-11 are repeated and the foam volume is recorded as the foam volume at 150 revolutions. Further addition of the soiled fabric to the cleaning liquid in the SCT cylinder mimics the actual cleaning conditions, and as the cleaning cycle continues, more dirt is gradually dissolved from the fabric into the cleaning liquid. Therefore, this test relates to the measurement of the initial foam formation by the test detergent composition and the foam effect maintained over the cleaning cycle while more dirt gradually dissolves in the cleaning solution.
Gently pour a 13.37.5 mL wash solution sample (without any treated fabric pieces) from the SCT cylinder into a 300 mL beaker. 262.5 mL of RO water having a hardness of 0.27 g / L (16 gpg) (Ca / Mg of 4: 1) is added to the beaker, and a diluted solution having a total volume of 300 mL (referred to as “rinse solution”) is added. To form. Clean up any residual test solution and all stained fabric shavings from the SCT cylinder and wash the SCT cylinder with tap water. Pour 300 mL of rinse back from the beaker into the washed SCT cylinder. These steps are repeated for the test solution in each of the remaining SCT cylinders.
14. The power is turned on to the SCT, the cylinder is continuously rotated at a speed of 22 rpm for another 20 times, and the SCT is stopped. A picture is taken immediately after the SCT is stopped and the bubble height is read from the picture (in the sample of the present invention, the bubbles collapse very rapidly, so this is done to ensure the accuracy of the data). This is recorded as the bubble volume at 0 minutes after 170 rotations. This foam data, measured after the wash solution, replaces the rinse solution. Therefore, it is recorded as "rinse foam" at 0 minutes.
15. Another reading of the foam volume in the SCT cylinder is performed 1 minute after the SCT is stopped at 170 revolutions (this is referred to as "rinse foam in 1 minute").
16. The rate of reduction of foam from 0 minutes to 1 minute using the rinse solution during the first rinse is calculated as follows.
