PEEA Gel Dispensing High Perfume Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing volatile material dispensers, such as air-fresheners, require high amounts of carrier materials to deliver a suitable level of active volatile components like perfumes, and existing solutions either limit the perfume concentration or require additional support, making it difficult to achieve high perfume loads while minimizing carrier usage.
Innovation Solution
A self-supporting gel composition comprising up to 97.5% active volatile liquid component and 2.5% to 30% thermoplastic polyether-ester-amide elastomer (PEEA), which forms a rubber-like solid capable of fully entrapping high quantities of perfume, allowing for prolonged fragrance diffusion with minimal carrier constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high amounts of carrier materials are used to deliver active volatile components, then the delivery performance is improved, but the total mass of the dispenser increases
Solution Approach 1:
The patent changes the physical-chemical parameters of the carrier material by using a specific polyether-ester-amide elastomer with controlled molecular weight and structure. This allows the carrier to achieve high perfume loading (up to 97.5% active volatile) while maintaining self-supporting properties, thereby reducing total carrier mass and dispenser weight while preserving fragrance delivery performance.
Solution Approach 2:
The invention uses a composite gel system combining polyether-ester-amide elastomer with specific perfume formulations. This composite material achieves synergistic effects where the elastomer matrix efficiently entraps high concentrations of volatile components, improving delivery performance per unit mass and reducing the overall carrier quantity needed.
2Productivity
If high concentrations of perfume are used, then the fragrance delivery performance is improved, but the composition stability deteriorates
Solution Approach 1:
The patent modifies the molecular parameters of the elastomer (molecular weight, polyether-ester-amide structure) to optimize the balance between perfume solubility and composition stability. The specific elastomer structure provides uniform dispersion and stable entrapment of high perfume concentrations, preventing phase separation and maintaining composition homogeneity even at 97.5% active volatile content.
Solution Approach 2:
The polyether-ester-amide elastomer acts as an intermediary matrix that mediates between the perfume components and the external environment. It provides a stable molecular network that uniformly distributes and releases volatile components, maintaining composition stability while enabling high perfume loading.
3Weight of stationary object
If existing gel compositions are used to reduce carrier mass, then the carrier amount is reduced, but the gel requires additional support structures
Solution Approach 1:
The patent optimizes the physical parameters of the elastomer (molecular weight, gelation conditions) to achieve a self-supporting gel matrix with appropriate mechanical strength. The gel composition maintains structural integrity without requiring additional support structures, enabling carrier mass reduction while preserving form stability and dispensing functionality.
Solution Approach 2:
The polyether-ester-amide elastomer forms a self-supporting gel network that provides its own structural support for holding and releasing perfume. The gel matrix is self-sufficient, eliminating the need for external support structures or additional carriers, thereby reducing overall device complexity and carrier mass.
4Quantity of substance
If functionalized polymers with cross-linking agents are used, then the perfume entrapment capacity is improved, but the perfume formulation flexibility is limited
Solution Approach 1:
The patent changes the chemical parameters of the elastomer to a polyether-ester-amide structure with specific functionality that provides universal compatibility with various perfume formulations. The elastomer's molecular structure allows it to entrap diverse volatile components (esters, aldehydes, alcohols) without requiring specific cross-linking agents or formulation adjustments, thereby maintaining both high entrapment capacity and formulation flexibility.
Solution Approach 2:
The polyether-ester-amide elastomer serves as a universal carrier matrix that can accommodate multiple types of volatile components and perfume formulations. Its multi-functional properties include entrapment, dissolution, and release of various active volatile substances, eliminating the need for formulation-specific cross-linking agents and enabling versatile perfume composition design.
