Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current detergents and fabric softeners fail to provide sufficient softening and fragrance delivery to fabrics during the wash cycle, limiting consumer control over the amount of softening agents used.
Innovation Solution
A composition for fabric treatment comprising a cationic polymer, water-soluble carrier, fragrance, buffer system, and optional silicone, rheology modifier, emulsifying substance, colorant, bittering agent, and solvent, which forms melt bodies that can be added to the wash cycle to enhance fabric softness and fragrance delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional detergents and fabric softeners are used, then fabrics are washed and maintained, but the softening effect is insufficient and consumers cannot control the amount of softening agents
Solution Approach 1:
The invention separates the softening function from the detergent by using a distinct solid composition containing cationic polymer softening agents. This allows consumers to independently control the amount of softening agent added to the wash cycle, while the detergent handles cleaning. The solid composition is a separate, measurable product that can be dosed independently of the liquid detergent.
Solution Approach 2:
The solid composition acts as an intermediary carrier that delivers cationic polymer softening agents to the fabric. This intermediary form (solid melt body) enables precise metering and control of the softening agent amount, while the cationic polymer itself provides the reliable softening effect on fabric contact.
2Ease of operation
If solid compositions with fragrance are used, then consumers can control fragrance delivery, but additional softening is not provided
Solution Approach 1:
The invention merges multiple functions into a single solid composition: fragrance delivery, fabric softening, and static control. The solid melt body contains cationic polymer softening agents along with fragrance, allowing consumers to control both softening and fragrance delivery simultaneously through a single metered addition to the wash cycle.
Solution Approach 2:
The solid composition serves multiple functions: it acts as a fragrance carrier, a fabric softener through cationic polymer deposition, and a static control agent. This multi-functional solid product replaces the need for separate fragrance and softening treatments, providing universal benefit in a single customizable dose.
3Reliability
If more softening agents are added to achieve greater softness, then fabric softness improves, but the complexity of the washing system increases
Solution Approach 1:
The invention uses a disposable solid composition (melt body) that is added to each wash cycle as needed. This single-use solid form eliminates the need for complex dosing systems, pumps, or reservoirs. The consumer simply adds the appropriate amount of solid composition to the drum, and it dissolves and releases the cationic polymer softening agents during the wash cycle.

AI summary
Solid particulate compositions for fabric treatment having at least one cationic polymer, at least one water-soluble carrier, at least one fragrance, at least one buffer system, and other optional ingredients. During a wash cycle, the compositions deliver softening to the fabrics. The disclosure further provides a method of making a solid particulate composition for fabric treatment including: mixing a water-soluble solid carrier and a buffer system to form a mixture; wherein the solid carrier is an aqueous salt having a water vapor partial pressure at a temperature from about 30° C. to about 100° C. that corresponds to the water vapor partial pressure of a saturated solution of the salt at the same temperature; adding a cationic polymer and a fragrance into the mixture; mixing the mixture; heating the mixture and obtaining a melt thereby; and cooling and shaping the melt into individual particles including melt bodies.
