Solid Textile Care Composition with Coated Clay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fabric softeners cannot be used simultaneously with laundry detergents due to interactions with anionic surfactants, requiring an additional rinse cycle, and often leave unsightly deposits and fail to prevent lime scale residue.
Innovation Solution
A solid textile and/or skin care composition comprising a water-soluble carrier, textile-softening clay, and skin care compounds that can be used in the main wash cycle with laundry detergents, eliminating the need for a separate rinse cycle and preventing lime scale deposits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fabric softeners are used, then textile softening is achieved, but additional rinse cycles are required and lime scale deposits occur
Solution Approach 1:
The invention combines fabric softening, water softening, and fragrance functions into a single solid composition that can be applied during the main wash cycle. The composition includes textile-softening clay particles coated with a solution containing cationic fabric softening compounds, water softening agents, and fragrance, allowing simultaneous achievement of multiple functions without requiring separate rinse cycles.
Solution Approach 2:
The solid composition serves multiple functions: it softens textiles through cationic compounds, prevents lime scale deposits through water softening agents, and provides fragrance. This multi-functional approach eliminates the need for separate fabric softener applications and addresses multiple problems with a single product.
2Ease of operation
If conventional fabric softeners are used, then textile softening is achieved, but unsightly deposits are left in the dispensing draw
Solution Approach 1:
The invention changes the physical state of the fabric softening composition from liquid to solid form. The solid composition, consisting of clay particles coated with the active solution, does not leave liquid residues or unsightly deposits in the dispensing draw, while still effectively softening textiles when applied to the washing.
3Ease of operation
If cationic fabric softening compounds are used with anionic surfactants, then textile softening is achieved, but interaction problems occur requiring separate application
Solution Approach 1:
The invention merges cationic fabric softening compounds with anionic surfactants and water softening agents into a single stable solid composition. The clay particle structure allows coexistence of oppositely charged compounds without premature interaction, enabling simultaneous application during the main wash cycle without the complexity of separate application processes.
