Pressurized Gel Formulation with Gas Propellant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sunscreen and other topical formulations are often perceived as heavy, sticky, or greasy, leading to poor user compliance due to aesthetically unpleasing application processes and uneven coverage, which can result in inadequate application and wastage.
Innovation Solution
A pressurized gel formulation co-mingled with a whipping agent, such as a gas propellant, is developed to create a whipped product that maintains pressure until all formulation is expelled, providing even coverage and improved user experience without the propellant co-mingling with the product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional sunscreen formulations are used, then the product provides sun protection, but the formulation is perceived as heavy, sticky, or greasy leading to poor user compliance
Solution Approach 1:
The patent transforms the physical state and texture parameters of the sunscreen formulation by incorporating gas propellants and whipping agents, changing it from a conventional heavy, sticky gel to a lightweight, airy whipped foam that expands upon dispensing, thereby improving user compliance while maintaining sun protection efficacy
Solution Approach 2:
The formulation utilizes phase transition of gas propellants from compressed liquid/gas state in the canister to expanded foam state upon dispensing, creating a lightweight whipped texture that eliminates the heavy, sticky perception while delivering adequate sunscreen coverage
2Reliability
If more sunscreen is applied to ensure adequate coverage, then better protection is achieved, but the heavy and sticky texture makes application less appealing
Solution Approach 1:
The whipped foam formulation changes the density and volume parameters of the product, allowing a larger volume of sunscreen to be applied with less perceived weight and stickiness, making the application process more appealing while ensuring adequate coverage through the expanded foam structure
3Reliability
If sunscreen is applied liberally as instructed, then adequate protection is achieved, but the product becomes wasteful and difficult to apply evenly
Solution Approach 1:
The whipped foam formulation optimizes the volume-to-mass ratio and spreadability parameters, allowing the product to be applied evenly across the skin surface with better distribution control, reducing both wastage and ensuring reliable protection effectiveness
4Stability of the object's composition
If conventional gel formulations are used, then the product maintains stability, but the formulation is difficult to spread evenly on skin
Solution Approach 1:
The patent modifies the rheological and textural parameters of the formulation by incorporating gas propellants and whipping agents, transforming the dense gel structure into a lightweight whipped foam that maintains compositional stability while significantly improving spreadability and ease of application on skin
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 solution results in a lightweight, easily spreadable, and aesthetically pleasing whipped gel that ensures confident sunscreen coverage while maintaining moisturization and protection properties, improving user compliance and application efficiency.
Implementation Method 1
The gas propellant is added in sufficient amounts to be dispersed in the formulation
Implementation Method 2
the package maintains at least a minimal amount of pressure to maintain the whipping agent dispersed in the formulation
Implementation Method 3
the component is present in the package in sufficient amounts and pressure to expel the formulation as a whipped formulation upon application of external force on the formulation in the package
