Abstract:
The present invention discloses a method for manufacturing a four-phase heavy-duty laundry detergent wipe, characterized by the following steps: (a) manufacturing a liquid starting laundry detergent solution which contains enzymes, surfactants and at least one polyvalent alcohol as a solubilizer and which is present in a liquid phase; (b) incorporating soap in the liquid starting laundry detergent solution to obtain a liquid laundry detergent solution (A), wherein the liquid laundry detergent solution is two-phase due to over-saturation; (c) admixing at least two different washing active solid components to the liquid laundry detergent solution (A) which are insoluble in the polyvalent alcohols of step a) to obtain a laundry detergent dispersion (B) which contains the liquid over-saturated two-phase laundry detergent solution (A) from step b) as a liquid continuous outer binary phase and the at least two washing active solid components as a solid phase; (d) applying the laundry detergent dispersion (B) to a solid carrier substrate (C) such that the final product is a four-phase system. Furthermore, a four-phase heavy-duty laundry detergent wipe is disclosed, comprising a solid carrier substrate (C) and a laundry detergent dispersion (B) which has been applied to the carrier substrate, characterized in that the laundry detergent dispersion contains a liquid over-saturated two-phase laundry detergent solution (A), which contains enzymes, surfactants and soap and at least one polyvalent alcohol as a solubilizer, as a liquid continuous outer binary phase and at least two different washing active solid components as a solid phase which is insoluble in the solubilizer.
