Description

  • The present invention relates to a viscous wash product and a package therefor.
  • It is an object to provide an improved pre-treatment device for the precise pretreatment of laundry stains.
  • Accordingly, in one aspect, the present invention provides a packaged laundry product comprising a flowable laundry detergent contained in a bottom-releasing package
    • (i) the flowable detergent has a viscosity of at least 100 Pa · s, preferably at least 500 Pa · s, when at rest or up to a shear stress of 10 Pa and comprising at least one surfactant and at least one hydrotrope, and
    • (ii) the bottom-dispensing package comprises a compressible container in which the flowable detergent is contained and a dispenser device incorporating a tissue pretreatment device, wherein the dispenser device and the tissue pretreatment device are located at the bottom of the compressible container.
  • The advantage of the above arrangement is that it provides greater control when applying a high viscosity composition to soiled areas. Pretreatment with high viscosity fluids from hand-held products is advantageous in terms of accuracy of application to the soiled area. However, this can be ergonomically difficult and many users apply impact force to the device (beating the base or tapping the side), which interferes with accurate dosing and often results in overdose, spillage, etc.
  • This arrangement, as a result of the positioning of the dispenser / pre-treatment part at the base of the container, means that the user does not need to invert the package in order to dose / pretreat or wait until the viscous liquid on the base flows to the top ( where dispensers / pre-treatment devices are normally attached). In the present invention, gravity keeps the pretreatment device loaded with the agent. While the propensity of high viscosity products to remain in place during a pretreatment is beneficial, it can often still persist through the washing process and leave its own mark on the fabric after the washing process has begun. This is often the case especially for short wash cycles or for "eco-friendly" washings with little water. The presence of a hydrotrope facilitates solubilization of the stain-applied agent and thereby faster release during washing.
  • Preferably, the tissue treatment container is closed by a dosage closure device which provides a bearing base of the packaging.
  • The advantage of this arrangement is that the dispensing device does not require complicated and expensive seals / valves since the dosing closure encloses the pretreatment device and provides the base: this offers the advantage that drops of the agent that fall out of the pretreatment device after use, in the bearing base, which can then be placed directly into the washing machine / receptacle, minimizing waste.
  • The dispensing device may include a channel or conduit that provides fluid communication between the reservoir and the pretreatment agent.
  • The pretreatment means may comprise a device which allows mechanical cleaning, for example a body with many projections.
  • The projections can be flexible so that they move during cleaning, providing a light cleaning process. Alternatively, some or all of the projections may be semi-rigid or rigid so as to provide a stronger mechanical cleaning process. The projections may be thin, for example bristles, to provide a brush-like device or may be thicker so as to provide finger-like projections.
  • The package may have a curved top to keep users from storing the bottle upside down. In this way, the packaging will most likely be in one Pre-treatment agent loading position stored, that is, with the flowable detergent by gravity accumulated in the base of the package.
  • In one embodiment, the pretreatment means comprises a generally hemispherical body having many projections extending radially therefrom.
  • The composition may comprise 0.1 to 10% by weight of hydrotrope, preferably 0.1 to 5%, more preferably 0.1 to 2%, and most preferably 0.1 to 1% of hydrotrope.
  • Possible hydrotropes include toluene, urea, cumenesulfonate, xylenesulfonate and mixtures thereof. Salts include sodium, potassium, ammonium, monoethanolamine, triethanolamine and mixtures thereof. One combination is xylene sulfonate and urea.
  • The agent is preferably a shear-thinning gel-type agent. The shear stress may be less than 300 Pa · s, preferably less than 100 Pa · s, and more preferably less than 5 Pa · s, even more preferably at most 1 Pa · s, and most preferably at most 0.5 Pa · s ,
  • Shear thinning agents may include a polymer gum, for example, xanthan gum or other gum capable of forming stable continuous gum networks that can suspend particles.
  • Other external structurants, for example hydrogenated castor oil, microcrystalline cellulose, may be used.
  • Another method useful for altering a non-gelled formulation to form an internal structure therein, which structure provides the desired properties of the gel-type detergent thus formed, can be used. The agent may comprise a soap or a fatty acid in combination with sodium sulfate, and it may be a surfactant or a plurality of surfactants may be used to form a gelled structure through the formation of lamellar phases.
  • The composition may comprise lamellar phase dispersions of a micellar surfactant system and additionally a structuring agent for the development of the lamellar phase, wherein the structurant may be a fatty alcohol.
  • The composition of the invention contains one or more surfactants and / or optional other ingredients such that the agent is fully functional as a laundry cleansing and / or conditioning composition. An agent of the invention may be provided in solid or liquid form. When provided in solid form, the agent may be rehydrated and / or dissolved in a solvent, including water, before use. The agent may be provided in a concentrated form for dilution or may be a ready-to-use agent.
  • The present invention is suitable for use in industrial or household fabric laundry detergents. The present invention may also be applied to industrial or household non-detergent based fabric care compositions.

  • 1 shows a packaged laundry product according to an embodiment of the invention.
  • As far as the drawing is concerned, it becomes a packaged laundry product 1 shown. The product 1 includes a flowable detergent 3 in a packaging 5 wherein the high viscosity detergent 3 corresponds to Example A or B described in detail below.
  • The package comprises a compressible container, in this example a plastic bottle 7 containing the flowable wash gel 3 high viscosity, and a dispensing device 9 containing a fabric pre-treatment device 11 has installed. The dispenser device 9 is located at the base 13 of the container 7 and is from a dosing closure device 13 locked in. The closure 13 includes the supporting base 13 the packaging 5 ,
  • The bottle 7 and the dispenser device 9 (including pretreatment agents 11 ) are interconnected by screw connection. The closure 13 is also connected by a screw with the bottle (screw not shown). In a separate embodiment, the closure becomes 13 using a snap connection with the bottle 7 connected, this snap connection does not require turning the bottle / closure on / to.
  • The bottle 7 is made of a flexible plastic material comprising polyethylene terephthalate.
  • The top 21 the bottle is shown flat, but it may be curved in other embodiments, as is the dashed line 22 indicates to prevent upside down storage.
  • The closure 13 comprises an enlarged (with respect to at least the neck region of the bottle) flat, generally planar bottom surface 15 , By having an enlarged flat top 15 is provided, the surface allows the shutter 13 as a supporting base with the bottle 7 acting in reverse position to thereby the gel 3 high viscosity (under gravity) during storage on the dispenser 9 to collect.
  • In addition, the closure includes 13 a reservoir part 17 in which the pretreatment agent 11 is included, 26 , The shutter is outward towards the surface 15 glued to provide a stable base. The area of the surface 15 is bigger than the top 21 the device.

  • In one embodiment, the membrane has a bent portion (not shown) that faces the container 7 is directed. The bent portion of the membrane is equipped with intersecting slots to define a plurality of generally triangular blades. As contents of the container for dispensing are pressurized, the triangular blades flex toward the open end of the opening 25 , passing product through the opening 25 let go. As the dispensing pressure is released, the triangular blades spring back to their original position and act to block a product passageway through the opening 25 , The blades of the valve are sufficiently elastic that they will not flex open unless the applied pressure exceeds the hydraulic static head pressure created by a filling of seasoning. In use, the fluid is pressurized to pass and partially becomes the pretreatment agent 11 collected, ready for cleaning.
  • Some of the fluid in the pretreatment center part 11 may remain during storage from the pretreatment agent 11 drip and gets into the reservoir part 17 collected for use in the next wash. This reduces waste of the product.
  • Exemplary detergent formulation A
  • The following gel detergents were prepared, wherein agent A is according to the invention. component Wt .-% propylene glycol 8.0 sodium citrate 3.9 borax 3.0 NaOH (50%) 1.1 Monoethanolamine 1.0 LAS acid 4.4 coconut fatty acid 1.5 Nonionic surfactant 11.1 oleic acid 2.3 1-dodecanol 5.0 Protease enzyme 0.3 Lipase enzyme 0.5 Perfume 0.2 Water rest on 100
    in which:
    Borax: sodium tetraborate (10 aq)
    nonionic surfactant: ethoxylated alcohol with an average of 9 ethylene oxide groups.
  • It has been found that the gel detergent, for which Agent A is an example, is shear thinning and stable. In addition, typical detergent particles with a density between 0.8 and 0.9 g / cm 3 and having a diameter of up to 5000 μm, be stably suspended in this medium for more than 2 weeks without any observable net movement of the particles. sample Viscosity / Pa.s Eta 0 critical tension Tan-Delta 20 s -1 100 s -1 Pa.s Pa at 1 Hz A 2.11 0.61 3.00 E + 05 15 0.04
  • To obtain the values shown in the above table, all rheological measurements were made using a Carrimed CSL 100 rheometer with a cone and plate geometry specially roughened to prevent slippage.
  • Viscosity was measured at varying shear rates from very slow shear to a shear plan in excess of 100 s -1 . Two situations are shown: viscosity measured at relatively low shear (20 s -1 ) and that measured at much higher shear (100 s -1 ). It can be seen that the viscosity of high shear agent A is much lower than that observed at low shear whereas high and low shear agent B shows almost the same viscosity. In other words, means A becomes thinner in shear, whereas means B does not.
  • In addition, the critical stress is shown. This parameter represents the stress at which the material leaves the upper Newtonian plateau and becomes thinner under increased shear. "Eta 0" values are also shown, referring to the viscosity calculated for shear from creepage measurements.
  • Finally, "tan-delta" values are given that relate to the loss ratio over storage moduli (G "/ G ') and reflect the dominance of viscous versus elastic properties, so that materials that are very low" tan-delta " Values (zero bias, e.g. mean A in the above table) will be much more elastic than those giving higher "tan delta" values (90 bias).
