Solution Overview
Problem
Existing laundry detergents, particularly in pouch form, face challenges in providing a precise, concentrated, and environmentally friendly solution that effectively cleans across varying wash temperatures and load sizes while offering customizable fragrances.
Innovation Solution
Development of a water-soluble, biodegradable pouch made from polyvinyl alcohol derivatives containing a surfactant-rich detergent composition with enzymes, solvents, and fragrances, designed to dissolve in cold water and include a range of active and inert components for enhanced cleaning and fabric care.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If laundry detergent is formulated as a concentrated pouch, then space efficiency and dosing precision are improved, but dissolution performance across varying temperatures may deteriorate
Solution Approach 1:
The patent modifies the physical and chemical parameters of the detergent formulation, including using low-foiling surfactants and adjusting ingredient concentrations, to enable effective dissolution and cleaning performance across a wide temperature range (15°C to 60°C) while maintaining high concentration in pouch form
Solution Approach 2:
The detergent comprises a composite formulation combining multiple surfactants (anionic, nonionic, amphoteric), enzymes, and auxiliary ingredients in specific ratios that work synergistically to maintain both concentration efficiency and reliable dissolution across varying wash temperatures
2Adaptability or versatility
If multiple fragrance options are offered, then consumer preference satisfaction is improved, but formulation complexity and manufacturing variability increase
Solution Approach 1:
The detergent is formulated as a base composition that can be segmented into different fragrance variants while maintaining the core cleaning formulation, allowing multiple fragrance options to be produced from a standardized base formula
Solution Approach 2:
The detergent formulation serves multiple functions simultaneously: cleaning, fabric care, and fragrance delivery. The universal base formulation accommodates different fragrance additives without requiring complete reformulation, enabling versatility while controlling complexity
3Object-affected harmful factors
If biodegradable materials are used for the pouch, then environmental friendliness is improved, but structural integrity and water solubility control may deteriorate
Solution Approach 1:
The pouch material parameters are specifically engineered to balance biodegradability with functional performance, selecting materials that maintain structural integrity during storage and handling while ensuring complete dissolution and biodegradation after use

AI summary
A composition for use in a laundry pouch comprises a first surfactant, an ethoxylated alcohol, a protease enzyme, an amylase enzyme, and a mannanase enzyme. The composition may be used in a pouch or added as a liquid detergent to a laundry wash. The laundry detergent composition may comprise a composition having at its essence a surfactant and an enzyme. The detergent composition may comprise more than one surfactant. Various enzymes may be used for stain removal or other reasons based on cleaning or treatment properties of such enzymes.
