Flexible Water-Soluble Detergent Sheet Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry detergents, whether in liquid or powder form, often fail to fully dissolve in washing machines, leaving residues and requiring additional washing cycles, and existing detergent sheet solutions either do not dissolve or are complex to produce.
Innovation Solution
A flexible detergent sheet composition comprising 10-15% water-soluble polymeric component, 30-37% anionic surfactant, 7-10% non-ionic surfactant, 1-4% mineral oil, 11-17% glycerin, 1-4% coconut diethanolamide, 18-25% water, and 0.5-2% supplementary components, which forms a solid sheet that dissolves completely in water, releasing active ingredients during washing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If powder detergent is used, then cleaning effectiveness is maintained, but residues form in the washing machine and on clothes due to incomplete dissolution
Solution Approach 1:
The invention changes the physical state parameter of the detergent from powder to a water-soluble flexible sheet form. This parameter change enables complete dissolution in water while maintaining cleaning effectiveness, thereby eliminating residue formation in the washing machine and on clothes.
Solution Approach 2:
The detergent sheet is formulated as a composite material containing surfactants, polymers, and other detergent components embedded in a water-soluble matrix. This composite structure allows the detergent to maintain its cleaning properties while ensuring complete solubility, preventing both machine and fabric residues.
2Object-generated harmful factors
If liquid detergent is used, then fluidity and residue prevention are improved, but handling becomes impractical and cleanup is difficult in case of spills
Solution Approach 1:
The invention uses a flexible sheet form factor that combines the advantages of both liquid and powder detergents. The thin film structure provides complete solubility like liquids while maintaining solid handling properties, making it easy to store, transport, and use without spill concerns.
Solution Approach 2:
The detergent is transformed from liquid to a semi-solid flexible sheet through parameter changes in its physical state. This transformation maintains the complete solubility and residue-free performance of liquids while gaining the handling convenience and spill-resistance of solids.
3Ease of operation
If existing detergent sheets with substrates are used, then sheet form handling is achieved, but the substrate remains in the washing machine after washing due to inability to dissolve
Solution Approach 1:
The invention extracts and eliminates the non-dissolving substrate component from traditional detergent sheets. The active detergent ingredients are formulated to be completely water-soluble without requiring a persistent substrate, ensuring that the entire product dissolves completely in the washing machine while still providing convenient sheet-form handling.
Solution Approach 2:
The detergent sheet uses a completely water-soluble composite formulation where all components including the matrix material are designed to dissolve. This eliminates the residual substrate problem while maintaining the convenient sheet form factor for handling and dosing.
4Strength
If multi-layer detergent sheets with nonwoven materials are used, then structural integrity is improved, but production complexity increases and non-soluble elements are introduced
Solution Approach 1:
The invention simplifies the detergent sheet structure by using a single-phase completely water-soluble formulation rather than multi-layer constructions. This parameter change in structural complexity reduces production steps while maintaining adequate structural integrity through the viscoelastic properties of the soluble polymer matrix.

AI summary
The present invention describes a detergent composition in the form of a flexible sheet, which in turn is soluble in water, and the water-soluble detergent sheet. Said detergent composition in the form of a flexible sheet comprises a unique mixture of components, including: a water-soluble polymeric component, an anionic surfactant, a non-ionic surfactant, water and other components. Once mixed in the appropriate proportions, the components produce a flexible sheet with detergent characteristics that can be incorporated directly into a clothes-washing recipient, said recipient ranging from a simple bowl to an advanced automatic washing machine. Once the detergent sheet comes into contact with water inside the washing recipient, the sheet dissolves and releases the active ingredients and complementary ingredients contained therein.
