Scent booster compositions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laundry detergents and fabric softeners fail to provide long-lasting, strong scents, especially at the stages of storing and wearing clothing, due to fragrance load limitations and loss of fragrance during washing and drying.
Innovation Solution
A scent booster composition comprising a pastille formulation with fragrance microcapsules, free fragrance, clay, and polyethylene glycol, optionally combined with a sodium chloride system, to enhance and prolong fragrance release in laundry applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If current laundry detergents and fabric softeners are used, then they can provide basic fragrance, but they cannot provide long-lasting, strong scent at the stage of storing and wearing clothing due to fragrance load limitation and loss of fragrance during washing and drying
Solution Approach 1:
The fragrance is divided into two delivery systems: free fragrance that releases quickly during washing, and encapsulated fragrance in microcapsules that releases gradually during storage and wear. This segmentation allows different portions of fragrance to be delivered at different times, extending the overall duration without requiring excessive total fragrance load.
Solution Approach 2:
Microcapsules act as an intermediary carrier that protects the fragrance from premature loss during washing while enabling controlled release during storage and wear. The microcapsule wall serves as a mediator that regulates fragrance release timing, allowing the fragrance to persist longer without being lost during the washing process.
2Quantity of substance
If free fragrance is formulated at a high level to achieve desired scent, then strong scent is achieved, but fragrance is lost during washing and drying
Solution Approach 1:
Microcapsules serve as an intermediary protective layer that prevents fragrance loss during washing and drying. The encapsulated fragrance remains trapped within the microcapsule wall during the washing process, preventing it from being washed away or evaporating during drying, thus maintaining fragrance intensity without excessive loss.
Solution Approach 2:
The fragrance is transformed from a free state that is easily lost to an encapsulated state within microcapsules that protects it during washing and drying. This parameter change in the physical state of the fragrance (from free to encapsulated) reduces fragrance loss while maintaining the ability to deliver strong scent when needed.
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 provides a long-lasting, high-performance scent that is more intense and durable, maintaining fragrance intensity throughout the laundry cycle and beyond, even after storage and wear.
Implementation Method 1
a microcapsule core and a microcapsule wall encapsulating the microcapsule core, in which the microcapsule core contains a fragrance
Implementation Method 2
0 to 25% a clay
Implementation Method 3
50 to 70% polyethylene glycol that has a molecular weight of 2,000 to 10,000
Implementation Method 4
a sodium chloride system containing by weight of the system (i) 1 to 30% a free fragrance and (ii) 70 to 99% sodium chloride
