Solid Perfume Composition for Fabric Color Fading Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fabric treatment compositions do not effectively boost color fading protection for textiles during washing, despite the use of chlorine scavengers, which provide only a baseline level of protection.
Innovation Solution
A solid, particulate composition comprising a water-soluble carrier, a dye transfer inhibitor (DTI), a buffer system, and a fragrance, which is added to the wash cycle to provide enhanced color fading protection and fragrance delivery to fabrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chlorine scavengers are used in detergents and fabric softeners, then baseline color fading protection is provided, but enhanced color fading protection is not achieved
Solution Approach 1:
The patent combines multiple beneficial agents (dye transfer inhibitors, fragrance, buffer system) into a single solid composition that can be separately metered into the washing drum. This merging approach allows consumers to add enhanced color protection without using multiple separate products, resolving the contradiction by integrating multiple functions into one composition while maintaining simplicity of use.
Solution Approach 2:
The invention uses a composite solid composition containing water-soluble carrier, dye transfer inhibitor, fragrance, and buffer system. This composite material provides enhanced color fading protection beyond what single-function products can achieve, while the solid particulate form maintains ease of handling and dosing.
2Adaptability or versatility
If solid compositions comprising melt bodies containing fragrance are used, then customizable fragrance delivery is achieved, but color fading protection is not boosted
Solution Approach 1:
The solid composition serves multiple functions simultaneously: it provides fragrance delivery with customizable metering control, enhances color fading protection through dye transfer inhibitors, and maintains fabric softness. This multi-functionality resolves the contradiction by making the same composition that enables versatile fragrance dosing also provide enhanced color protection.
Solution Approach 2:
The patent merges fragrance delivery capability with color protection functionality in a single solid composition. Consumers can control the amount added for fragrance while simultaneously receiving color fading protection, eliminating the need for separate products and resolving the contradiction between adaptability and reliability.
3Reliability
If multiple separate products are used to achieve enhanced color protection, then color fading protection is improved, but ease of operation deteriorates
Solution Approach 1:
The patent combines dye transfer inhibitors, fragrance, and buffer system into a single solid composition that can be added in one step. This eliminates the need to use multiple separate products (detergent, fabric softener, separate color protectors), thereby maintaining ease of operation while achieving enhanced color fading protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition significantly boosts color fading protection and fragrance delivery to fabrics, outperforming baseline protection methods by incorporating a DTI and buffer system, which work together to prevent dye transfer and enhance fabric color retention.
Implementation Method 1
comprising from about 20 to about 95 wt. % of at least one water-soluble carrier selected from aqueous salts
Implementation Method 2
from about 0.1% to about 10 wt. % of at least one buffer system; wherein wt. % is based on the total weight of the solid, particulate composition
