Encapsulated Perfume Delivery System for Cold Water and High Soil
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Detergent perfumes are less effective in high soil conditions and cold water due to hydrophobic perfume materials being attracted to soiled water, leading to wastage and residual odors on fabrics.
Innovation Solution
The use of specific perfume raw materials encapsulated in delivery systems, such as polymer-assisted delivery systems, to reduce interaction with soil and ensure controlled release, preventing wastage and odor buildup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If hydrophobic perfume materials are used in detergent formulations, then fragrance intensity and odor masking capability are improved, but perfume performance deteriorates in high soil conditions and cold water due to attraction to soiled water
Solution Approach 1:
The patent employs hydrophilic polymers as intermediary substances that bind to hydrophobic perfume materials through hydrophobic interactions. This creates a complex where the hydrophilic exterior of the polymer prevents the hydrophobic perfume from interacting with soiled water, while the hydrophobic interior maintains fragrance intensity. The polymer acts as a mediator that reconciles the conflicting requirements of odor masking and reliable performance in high soil conditions.
Solution Approach 2:
The patent changes the physical-chemical parameters of the perfume delivery system by incorporating polymers with specific molecular weights, hydrophobicity indices, and concentrations. These parameter adjustments optimize the balance between perfume release in cold water and prevention of perfume-soil interaction in high soil conditions, resolving the reliability issue while maintaining fragrance effectiveness.
2Object-generated harmful factors
If high levels of perfume materials are applied to ensure adequate fragrance, then odor masking is improved, but harsh odor and residue buildup occur on fabrics
Solution Approach 1:
The hydrophilic polymer serves as an intermediary carrier that enables the use of higher perfume levels for effective odor masking while preventing direct contact between perfume materials and fabric surfaces. The polymer matrix controls the distribution and release of perfume, ensuring adequate fragrance coverage without the harsh residual odors that would result from direct application of high perfume concentrations.
Solution Approach 2:
The patent creates local quality differentiation by having the polymer concentrate perfume release at specific locations and times. The hydrophobic regions of the polymer complex release fragrance locally where needed for odor masking, while the hydrophilic exterior prevents excessive accumulation on fabric surfaces, thereby avoiding harsh residue buildup.
3Use of energy by moving object
If traditional laundry detergents are used in cold water, then energy consumption is reduced, but perfume performance and soil removal effectiveness deteriorate
Solution Approach 1:
The hydrophilic polymer acts as a mediator that enables effective perfume delivery in cold water without requiring thermal energy. The polymer-perfume complex remains stable and functional at low temperatures, with the hydrophobic interactions maintaining integrity and the hydrophilic exterior ensuring proper dispersion in cold wash water, thus achieving reliable perfume performance with reduced energy consumption.
Solution Approach 2:
The patent adjusts formulation parameters including polymer concentration, molecular weight, and hydrophobicity to optimize performance in cold water conditions. These parameter changes enable the detergent to maintain effective perfume delivery and soil removal capabilities at lower temperatures, reducing the need for high-energy heating while preserving reliability.
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
Enhances perfume performance under high soil conditions and in cold water by maintaining fragrance on fabrics while preventing excessive perfume loss and odor issues.
Implementation Method 1
employing such perfumes via a perfume delivery system, for example, encapsulating such perfume compositions as described herein, further improves perfume performance under high soil conditions as the encapsulation decreases the interaction of the perfume raw materials with the soil
Implementation Method 2
perfume materials, the majority of which are relatively hydrophobic, are attracted to high levels of hydrophobic soil in such wash solutions, rendering them more likely to be washed away with the soiled water
