Laundry Scent Additive Pastille for Controlled Fragrance Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers who prefer strong perfume scents in their laundry often overuse laundry products, leading to a need for a cost-effective perfume scent additive that can be applied independently of other laundry products to achieve desired freshness levels.
Innovation Solution
A composition consisting of 80-91% polyethylene glycol with a molecular weight of 5,000 to 11,000, combined with 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 provide controlled fragrance to laundry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If consumers overuse laundry detergent and fabric softener to achieve strong perfume scent, then the desired freshness level is achieved, but the cost increases and product waste occurs
Solution Approach 1:
The invention extracts the perfume scent function from traditional laundry products (detergent and fabric softener) by providing a separate, dedicated scent additive. This allows consumers to achieve the desired fragrance level without increasing the quantity of laundry detergent or fabric softener used, thereby reducing product waste while maintaining scent concentration.
Solution Approach 2:
The invention segments the laundry care function into separate components: cleaning (detergent), softening (fabric softener), and scenting (perfume additive). This segmentation allows consumers to independently control and optimize each function, preventing the need to overuse multi-functional products to achieve strong perfume scents.
2Ease of manufacture
If consumers use a separate perfume scent additive, then cost-effectiveness improves and product independence is achieved, but the complexity of achieving desired scent levels increases
Solution Approach 1:
The invention uses parameter changes in the form of pre-defined fragrance concentration levels (e.g., light, medium, strong scent variants) to simplify consumer decision-making. Instead of requiring consumers to calculate and mix precise amounts to achieve desired scent levels, the product offers ready-to-use formulations with standardized fragrance intensities, reducing the perceived complexity while maintaining cost-effectiveness.
3Reliability
If polyethylene glycol with molecular weight 5,000 to 11,000 is used as the base material, then the pastille achieves optimal solubility and fragrance release, but the manufacturing precision requirements increase
Solution Approach 1:
The invention specifies a range for the molecular weight of polyethylene glycol (5,000 to 11,000) rather than a single precise value. This parameter range approach maintains optimal solubility and fragrance release performance while providing manufacturing flexibility, reducing the stringency of molecular weight control requirements and making the manufacturing process more robust.

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 solution provides a cost-effective and controlled method for achieving desired fragrance levels in laundry, independent of other laundry products, catering to 'scent seekers' preferences while minimizing perfume diffusion and formulation complexity.
Implementation Method 1
a composition consisting essentially of: (a) from about 80% to about 91% by weight of the composition of polyethylene glycol
Implementation Method 2
provide controlled fragrance to laundry
Implementation Method 3
from about 2% to about 12% by weight of the composition of friable perfume microcapsule, wherein the perfume microcapsule comprises encapsulated perfume
