Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid solubilizing systems for fragrances in consumer products face challenges in achieving stable suspension of microcapsules and long-lasting fragrance performance, particularly due to low viscosity and instability issues with charged surfactants, which limit compatibility and application in various substrates.
Innovation Solution
A self-thickened ringing gel composition with a viscosity between 0.1 and 1000 Pa·s at 0.01 s−1 shear rate, featuring a non-ionic surfactant system with a mean HLB between 10 and 14, a linker chosen from alcohols, salts, and esters, and an oil phase with a hydrophobic active ingredient, exhibiting viscoelastic behavior and capable of suspending microcapsules without sedimentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If microemulsion systems are used to solubilize fragrance, then fragrance performance is enhanced, but the system exhibits low viscosity which prevents stable suspension of microcapsules
Solution Approach 1:
The patent changes the rheological parameters of the system by introducing a viscoelastic gel network that increases viscosity from typical microemulsion levels (0.01-1 Pa·s) to gel levels (1-1000 Pa·s), enabling stable microcapsule suspension while preserving fragrance performance through the gel matrix
Solution Approach 2:
The invention creates a composite system combining microemulsion components (surfactants, oils, water) with gel-forming agents to produce a ringing gel composition that integrates the solubilization capabilities of microemulsions with the suspending properties of gels
2Stability of the object's composition
If external thickeners are added to increase viscosity for microcapsule suspension, then suspension stability is improved, but device complexity and formulation complexity increase
Solution Approach 1:
The patent merges the functions of fragrance solubilization (microemulsion) and viscosity enhancement (gel formation) into a single integrated system, where the gel network simultaneously provides both structural support for microcapsule suspension and maintains the solubilization environment for fragrance ingredients
Solution Approach 2:
The ringing gel composition exhibits self-thickening behavior where the gel network spontaneously forms and maintains the necessary viscosity for microcapsule suspension without requiring additional external thickeners or complex formulation adjustments
3Reliability
If charged surfactants are used to enhance solubilization, then fragrance performance is improved, but compatibility with various substrates is reduced
Solution Approach 1:
The patent employs non-ionic surfactants that provide sufficient solubilization capability while maintaining electrical neutrality, enabling the formulation to be compatible with various substrates (fabrics, skin, surfaces) that may have different surface charges or sensitivities to ionic components
