Three-phase heavy-duty laundry detergent wipe and method for manufacturing same

Abstract

The present invention discloses a three-phase heavy-duty laundry detergent wipe, comprising a substrate 1 which is solid at ambient temperature as a third phase and a dispersion applied to the substrate and consisting of a liquid washing detergent 5 as a first phase and a water insoluble functional additive 2 as a second phase; and a method for manufacturing same. In particular, the second phase, i.e., the additive 2, of the dispersion can be a zeolite. The substrate 1 can consist of fatty alcohols, viscose, polyethylene, polypropylene or polyester. Furthermore, the present invention discloses a homogeneous three-phase laundry detergent wipe and a method for manufacturing same, wherein the substrate is moistened with the dispersion via direct contact with a first moistening rod 3 which rests on one side of the substrate to be moistened and a second counter moistening rod 4 which rests on the opposing side of the substrate to be moistened such that the washing active substances and solid components of the dispersion 2, resp., are distributed homogeneously across the substrate after moistening.

Description

DESCRIPTION OF THE PREFERRED EMBODIMENTS

(1) Surprisingly, the inventive laundry product could be realized by incorporating additives such as zeolites into an impregnating solution in the form of a dispersion. A fine grain size and increasing the viscosity (>500 mPas) made a considerable reduction of sedimentation possible. While a dispersion is not possible in the field of liquid washing detergents, it has a decisive function for the inventive heavy-duty laundry detergent wipe.

(2) Due to the sedimentation effects, dispersions are currently not a physical form of laundry detergents because the objective of the latter is a continuous, i.e., statistically uniform and homogeneous, resp., product which provides a constant product performance.

(3) The present invention makes the use of dispersions in a laundry detergent product possible for the first time. According the present invention, the continuous state desired for laundry detergent products has been achieved by applying a dispersion to a carrier material. The carrier material can be a non-woven, a fatty alcohol or a substrate for a phase combination of a dispersion with another separate phase.

(4) In total, the present invention consists of three phases. The first phase 5 of the dispersion is a liquid washing detergent concentrate consisting of washing active substances, enzymes, and, where appropriate, bleaching agents; the second phase 2 of the dispersion is a brightener/builder and a supportive substance for supporting dirt adsorption, resp., (for example, zeolite) in solid modification; the third phase 1 is a substrate in solid modification at ambient temperature onto which the mixture of 5 and 2 is applied, wherein the substrate can consist of fatty alcohols, viscose, polyethylene, polypropylene or polyester.

(5) The solid phase of the dispersion, i.e., the second phase 2, is a functional component of the inventive heavy-duty laundry detergent wipe. The first phase of the dispersion, i.e., the liquid washing detergent 5, can have a viscosity greater than 500 mPas. The substrate 1 serves the purpose to statistically fix the dispersion and consists of a raw material which is solid at ambient temperature. Finally, all known components of a heavy-duty laundry detergent can be included.

(7) The multiple mixing of the phases to a three-phase heavy-duty laundry detergent wipe makes the incorporation of a water insoluble brightener/builder and dirt adsorber, resp., into a liquid washing detergent and the necessary statistically stable uniform distribution via application on a substrate possible for the first time.

(8) FIG. 1 shows the result of moistening a substrate and a carrier material, resp., across a section of the substrate 1 by means of a moistening rod according to the prior art. As can be seen, the distribution of the washing active substances and solid components 2, resp., of the dispersion is not homogeneous. Surprisingly, the inventive laundry detergent wipe with a homogeneous distribution of the washing active substances and the solid components, resp., of the dispersion could be realized by installing two moistening rods in contrast to prior art methods, i.e., a first moistening rod 3 and a second counter moistening rod 4 which rest on opposing sides of the substrate and carrier material 1, resp., to be moistenedFIG. 2 shows this arrangement. Based on a moistening via direct contact with both moistening rods 3 and 4 it is possible for the first time to moisten the substrate 1 from both sides homogeneously with a lotion and dispersion, resp. The section across the moistened substrate in FIG. 3 shows the resulting desired homogeneous distribution of the washing active substances and solid components 2, resp., of the dispersion. Depending on the field of application, the dispersion to be applied can, for example, contain the ingredients shown in Tab. 1 above. As mentioned above, the use of the brightener/builderwhich can contain zeolitesis only possible in connection with the three-phase laundry detergent wipe but not with mere liquid washing detergents. The same applies to the phyllosilicates which can be used as an additive.
