Definitions
- the present invention relates to a liquid detergent composition for machine washing of clothes, to liquid unit doses comprising said liquid detergent composition and water-soluble capsules, as well as to methods of obtaining the detergent and liquid unit doses.
- the laundry detergent compositions available on the market are mainly classified into two types according to their physical appearance: conventional liquid detergents, with a water content of between 90, 50, or even 30% by weight depending on whether they are standard formulas or concentrated formulas; and powdered detergents, in solid form and with very little water.
- Liquid formulations are usually more suitable for washing clothes at moderate temperatures, given the greater ease of dispersion in water and the more respectful character with the tissues of its components.
- Both powder formulations and liquid formulations require the end user to dose them and put them in the washing machine. Often part of the product remains in its case or in the ducts that lead the product to the drum.

- PVOH-based water-soluble packages can be manufactured according to any of the horizontal encapsulation procedures described in any of WO-A-00/55044, WO-A-00/55045, WOA-00/55046, WO-A- 00/55068, WO-A-00/55069 and WO-A-00/55415.
- thermoforming process in which a series of packages according to the invention are produced from two sheets of water-soluble material.
- recesses are formed in the film sheet using a forming mold having a plurality of cavities with dimensions corresponding, in general, to the dimensions of the packages to be produced.
- a single heating plate is used for thermoforming the film for all cavities and in the same way a simple sealing plate is described.
- a first sheet of PVOH film is removed on a forming mold, so that the film is placed on the plurality of cavity formation in the mold.
- each cavity generally has a dome shape that has a round edge, the edges of the cavities are also rounded to eliminate all sharp edges that could damage the film during the formation or sealing stages of the procedure.
- Each cavity also includes a raised flange surrounding it.
- the film is released in the forming mold in a fold-free form and with minimal tension.
- the film is heated to 100-120 ° C, preferably at about 110 ° C, for up to 5 seconds, preferably 700 microseconds.
- a heating plate is used to heat the film, in which the plate is placed superimposed on the forming mold.
- a vacuum of 50 kPa crosses the preheating plate to ensure close contact between the film and the preheating plate, this close contact ensures that the film is heated evenly and homogeneously (the extent of the vacuum depends of the thermoforming conditions and the type of film used, however, in the present context it was found that a vacuum of less than 0.6 kPa was adequate).
- Non-uniform heating results in a formed package that has weak points.
- thermoformed film is molded into the cavities that blow the film from the heating plate by blowing and / or by absorbing the film into the cavities so that a plurality of recesses are formed in the film, which, once formed , they are preserved in their thermo formed orientation by applying a vacuum through the walls of the cavities. This vacuum is maintained at least until the packages are sealed.
- a liquid detergent composition according to the invention is added to each of the recesses. Then, a second sheet of polyvinyl alcohol film is superimposed on the first line through the loaded recesses and heat sealed using a sealing plate.
- the heat-heating plate which is generally flat, operates at a temperature of approximately 140-160 ° C and contacts the films for 1 to 2 seconds with a force of 8 to 30 kg / cm2, preferably of 10 to 20 kg / cm 2 .
- the raised tabs surrounding each cavity ensure that the films are sealed along the flange to form a continuous sack.
- each cavity is formed, at least partially, by a resiliently deformable material, such as, for example, silicone rubber. This results in the application of less force on the inner edge of the sealing flange to avoid damage caused by heat / pressure on the film.
- the packages formed are separated from the web of sheet film using cutting means. At this stage, it is possible to release the vacuum in the mold and eject the formed packages from the forming mold. In this way the packages are formed, loaded and sealed while they are introduced into the forming mold. In addition, they can also be cut while in the forming mold.
- the relative humidity of the atmosphere is controlled to approximately 50% humidity. This is done to maintain the heat seal characteristics of the film.
- a continuous tube of flexible plastic film is extruded. It is sealed, preferably by heat or ultrasonic sealing, at the bottom, loaded with the liquid composition, sealed again above the liquid film and then removed from the continuous tube by, for example, cutting.
- the present invention also provides a method for cleaning clothes comprising the use of water-soluble capsules containing a liquid detergent composition according to the invention.
- compositions of liquid laundry detergents in accordance with the invention preparation, appearance and dissolution capacity in water.
- Tables 1-3 summarize the compositions according to the invention (1-8), as well as the comparative examples (C1-C5), indicating the percentages of active material of each of the ingredients.
- the compositions are prepared at room temperature, following a normal process of mixing the components, stirring after each addition, until they are completely homogenized.
- Tables 1-3 also summarize the appearance and dissolution capacity in water of the concentrated compositions.
- the aspect is evaluated visually at room temperature, designating as “correct” that aspect in which the formula is transparent and homogeneous, and “incorrect” in case the composition has turbidity or phase separation.
- the dissolution capacity in water is evaluated visually and corresponds to the time it takes for the detergent composition to dissolve completely in water.
- 0.5g of the composition to be evaluated is weighed on a glass container 1.5cm high. Said container is in turn inserted into the base of a second larger glass container. 1000 mL of 20 ° HF hard water (544ppm Ca 2+ and 156ppm Mg 2+ ) are introduced into this second vessel, allowing it to slide slowly along the wall to avoid turbulence (speed around 3.0-3.5 mL / s). After one minute after adding the water, the mixture begins to stir at 200 rpm until complete dissolution of the composition to be evaluated.
- the solution in water is considered to be correct when the time does not exceed 160 s (average time corresponding to compositions of liquid detergents for water-soluble capsules present in the market).
- Table 1 show that the compositions according to the invention (1, 3) have a transparent and homogeneous appearance, unlike comparative examples C2 and C3 based on ethoxylated fatty alcohol as a nonionic surfactant alternative to the compound of ethoxylated glycerin.
- a transparent and homogeneous formulation is achieved by introducing a glycol type solvent into the composition. The dissolution capacity of those compositions that have a transparent and homogeneous appearance is correct in all cases.
- composition according to the invention (2) allows sodium citrate to be incorporated without losing the appearance and dissolution capacity in water required for this type of products.
- Glycerin 1 1.5 23.0 23.0 23.0 21.0 23.0
- Enzymes protease, amylase,
- the symbol “O” corresponds to transparent and stable compositions and the "X" to non-homogeneous compositions have turbidity or phase separation.
- the dissolution capacity of water is considered adequate "O" when it is at the level of market products.
- compositions of liquid laundry detergents in accordance with the invention effect of the chemical characteristics of ethoxylated glycerin compounds
- Table 2 shows different examples of compositions according to the invention (4-6) in which the structural and chemical characteristics (ester chain length and degree of ethoxylation) of ethoxylated glycerin compounds are varied.
- compositions of liquid laundry detergents according to the invention based on lauryl ether sulfate.
- Table 3 shows some examples of compositions in which lauryl ether sulfate is used as an anionic surfactant.
- Examples 7 and 8 based on glycereth-6 cocoate provide homogeneous and stable formulations, and with good dissolution capacity.
- comparative examples C4 and C5, based on ethoxylated fatty alcohol give rise to non-homogeneous formulations, even using glycol type solvents in the composition (case of comparative example C4).
- Table 4 summarizes the experimental data corresponding to the evaluation of detersive efficacy. This efficiency is established by determining the percentage of dirt removal present in standard tissue samples. Efficiency tests are carried out using a Miele Softtronic W5722 front-loading washing machine under the following conditions: synthetic program / mixture, spin speed 800 rpm, wash water temperature 20 ° C, water hardness 20 ° HF (544ppm Ca 2+ and 156ppm Mg 2+ ), load 2 kg of pre-described cotton towel and 35 grams of the detergent to be evaluated. In each detergency test different types of standard dirt are used, placing 3 specimens (dimensions 5x5 cm) for each type of fabric, in each wash. After the washing step, the tissue samples are allowed to air dry, at room temperature.
- Determination of detersive efficacy is performed by colorimetric measurements on standard soiled tissue before and after the washing process. These measurements are made using a colorimeter, for example the Datacolor International Spectraflash 600.
- Detersive efficacy is expressed as% detergency, calculated from the following mathematical formula, in which the CIE L * (Brightness) parameter is involved, coming from the colorimetric measurement.
- the percentage of detergency detailed in the table corresponds to the average value corresponding to the three specimens used for each type of tissue.
