Wrapped Laundry Composition for Enzyme and Fragrance Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry tablets face issues of poor enzyme stability, inability to incorporate essence microcapsules due to high-temperature drying, and reduced decontamination and softening effects due to direct addition of surfactants and softeners, leading to increased costs and environmental impact.
Innovation Solution
A laundry composition enveloping functional materials like softening particles, fragrant particles, and enzyme preparations in a film-forming wrapping material, using a specific ratio and composition of film-forming agents, surfactants, and bacteriostatic agents to maintain efficacy and prevent direct contact with air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If high-temperature drying (90-105°C) is used to prepare laundry tablets, then the tablets can be formed and stored, but enzyme stability deteriorates causing partial inactivation
Solution Approach 1:
The patent divides the laundry composition into separate functional modules: a film-forming wrapping material that provides protection, and functional particles (enzymes, softeners, fragrances) that are enveloped within. This segmentation allows the enzymes to be protected from high-temperature damage while still enabling tablet formation through the film-forming matrix.
Solution Approach 2:
The film-forming wrapping material acts as an intermediary protective layer between the enzymes and the high-temperature drying process. This intermediary structure allows the tablets to be formed and stored at high temperatures while the wrapping material protects the enzymes from thermal inactivation.
2Ease of operation
If conventional essence is added for fragrance extraction, then fragrance can be provided, but surfactants are consumed leading to reduced decontamination ability
Solution Approach 1:
The patent extracts the fragrance function from the traditional essence formulation and incorporates it as separate functional particles (fragrance microcapsules or solid fragrance carriers) that are enveloped within the film-forming matrix. This extraction allows fragrance to be provided without consuming surfactants, as the fragrance particles are physically separated from the surfactant system.
Solution Approach 2:
The patent creates a composite structure combining film-forming materials with functional particles including fragrance carriers. This composite approach allows multiple functions (decontamination, softening, fragrance) to coexist without interfering with each other, preventing surfactant consumption while maintaining decontamination ability.
3Ease of operation
If softener is directly added to laundry tablets, then softening function is provided, but anionic surfactant is consumed reducing decontamination effect
Solution Approach 1:
The patent segments the softening function into separate softening particles that are enveloped within the film-forming wrapping material, physically separating them from the anionic surfactants. This segmentation prevents the softener from consuming the surfactants while still providing the softening function when the tablet dissolves.
Solution Approach 2:
The film-forming wrapping material serves as an intermediary barrier that prevents direct contact and chemical interaction between the cationic softener and anionic surfactant. This intermediary structure allows both components to coexist without consuming each other, maintaining both decontamination and softening effects.
4Ease of operation
If PVA film is used to wrap laundry detergent pods, then convenience and portability are improved, but environmental friendliness deteriorates due to high plastic content
Solution Approach 1:
The patent changes the material parameter of the wrapping film from traditional PVA plastic to biodegradable film-forming materials such as starch-based polymers, cellulose derivatives, or other environmentally friendly polymers. This parameter change maintains the film-forming functionality for protection and portability while eliminating the environmental harm associated with PVA plastic.

AI summary
A laundry composition and a preparation method therefor are provided, relating to the field of household necessities. The laundry composition includes a wrapping material, a functional material enveloped in the wrapping material, and an adhesive for bonding the wrapping material; the wrapping material is a film-forming material with laundry function; the functional material is selected from one or more of a softening particle, a fragrant particle, an active oxygen particle, and an enzyme preparation. By enveloping the functional material in the wrapping material with a detergent function, the laundry composition has integrated functions of cleaning, decontamination, pliancy, and fragrance-retaining. Furthermore, since the granular softening particle, a granular fragrant particle, a granular active oxygen particle, and a granular enzyme preparation are not directly added in the wrapping material, even if the wrapping material is formed by high-temperature drying, the functional materials will not fail.
