Laundry Scent Pastilles for Controlled Perfume Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers who prefer strong perfume scents in their laundry often overdose on laundry products, necessitating a cost-effective, independent perfume scent additive for laundry that can provide desired freshness without interference from other products.
Innovation Solution
A composition comprising 80-91% polyethylene glycol with a molecular weight of 5,000 to 11,000, 2-12% free perfume, and 2-12% friable perfume microcapsules, shaped into pastilles with a mass of 0.95 mg to 2 g, which can be used as a unit dose to achieve desired scent levels without detergent or fabric softener actives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If consumers overdose laundry detergent and fabric softener to achieve desired scent strength, then the perfume scent intensity is improved, but the cost increases and the simplicity of use deteriorates due to interference from other product ingredients
Solution Approach 1:
The invention extracts the perfume scent function from complex laundry products (detergent and fabric softener) and places it in a separate, dedicated pastille formulation. This isolation eliminates interference from other ingredients while allowing consumers to precisely control scent intensity by adding only the required amount of pastille, without needing to overdose entire laundry product containers.
2Illumination intensity
If consumers overdose laundry products to achieve desired scent strength, then the perfume scent intensity is improved, but the cost increases
Solution Approach 1:
By separating the perfume scent function into a dedicated pastille product, consumers can precisely dose only the amount of scent additive needed, rather than paying for and using excessive amounts of entire laundry detergent or fabric softener containers. This enables cost-effective achievement of desired scent intensity.
Solution Approach 2:
The invention allows consumers to apply exactly the partial amount of perfume scent needed (through controlled pastille dosing) rather than requiring excessive application of entire laundry products. The pastille formulation enables precise, non-excessive dosing that achieves desired scent levels without waste.
3Illumination intensity
If the composition contains both free perfume and encapsulated perfume, then the scent experience is improved with balanced deposition, but the manufacturing complexity increases
Solution Approach 1:
The pastille formulation combines two different perfume delivery mechanisms (free perfume and encapsulated perfume) into a single composite material. This composite structure enables balanced scent deposition - free perfume provides immediate scent while encapsulated perfume provides controlled, sustained release - creating a superior scent experience that leverages the complementary properties of both forms.
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 balanced and detectable scent experience while ensuring physical and chemical stability, allowing for controlled perfume deposition on clothing during washing, thus avoiding overapplication of other ingredients.
Implementation Method 1
The viscous material is cooled below the glass transition temperature to form a plurality of pastilles
Implementation Method 2
passing the viscous material through small openings and onto a moving conveyor surface upon which the viscous material is cooled below the glass transition temperature to form a plurality of pastilles
