Laundry Detergent Sheet with Cellulase and Stiffening Agent

The patent applies parameter changes by carefully controlling the concentration and activity of cellulase enzymes in the detergent sheet, optimizing the balance between enzymatic cleaning capability and textile strength preservation. By adjusting enzyme parameters (concentration, activity level, and formulation conditions), the patent achieves effective pill removal while maintaining textile stiffness.

The patent uses composite materials by combining cellulase enzymes with other detergent components (surfactants, polymers, and stabilizers) in a formulated sheet structure. This composite approach allows the enzymes to work synergistically with other ingredients to achieve both cleaning effectiveness and textile strength maintenance.

The patent applies segmentation by formulating the detergent as individual unit sheets rather than bulk liquid or powder. Each sheet is a self-contained dose that can be easily handled and placed in washing machines, eliminating the need for complex dosing mechanisms while maintaining compact storage.

The patent utilizes phase transitions in the formulation, creating a sheet structure that transitions from a solid, stable form during storage to a dissolving state during use. This phase change approach simplifies manufacturing by allowing the detergent to be formed as a stable sheet that easily dissolves in water during the washing cycle.
