Solution Overview
Problem
Current scent boosters for laundry are not biodegradable and fail to meet consumer expectations for sustainability, as they often rely on non-biodegradable materials like clay and polyethylene glycol, which compromise performance.
Innovation Solution
A solid composition comprising a water-soluble, biodegradable carrier and core-shell microcapsules encapsulating fragrance agents, where the carrier is made from sugar alcohols and the shell is formed from melamine-formaldehyde or polyurea polymers, ensuring controlled release and enhanced fragrance perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If non-biodegradable materials like clay and polyethylene glycol are used as carriers in scent boosters, then the fragrance release performance is maintained, but the environmental sustainability is compromised
Solution Approach 1:
The invention changes the chemical composition parameters of the carrier material from non-biodegradable (clay, polyethylene glycol) to biodegradable alternatives, while adjusting the formulation to maintain fragrance release performance through controlled release mechanisms
Solution Approach 2:
The invention uses composite material structures combining biodegradable carrier materials with encapsulated fragrance compounds in core-shell microcapsules, creating a sustainable formulation that maintains functional performance while reducing environmental impact
2Object-affected harmful factors
If biodegradable materials are used as carriers in scent boosters, then environmental sustainability is improved, but the fragrance release performance may be compromised
Solution Approach 1:
The invention segments the fragrance delivery system into core-shell microcapsules where the biodegradable carrier material forms the shell structure, allowing controlled release of the encapsulated fragrance while maintaining sustainability
Solution Approach 2:
The biodegradable carrier material acts as an intermediary between the fragrance compound and the environment, controlling the release rate and providing a sustainable matrix that degrades after use while maintaining fragrance performance
3Reliability
If encapsulated fragrance components are used, then the fragrance perception on dry fabrics is enhanced, but the formulation complexity increases
Solution Approach 1:
The invention uses core-shell microcapsule structures where the fragrance compound is nested within the biodegradable carrier matrix, allowing controlled release and enhanced fragrance perception while providing a unified formulation approach
