Foaming Skincare Formulation with Pressure Generating Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skincare and sunscreen products often have a greasy texture, making them difficult to apply and spread on the skin, and they may not provide a desirable feel, leading to poor user compliance with reapplication recommendations, especially for sunscreens which require frequent application to ensure adequate protection against solar ultraviolet radiation.
Innovation Solution
A skincare formulation comprising a pressure generating vehicle, such as compressed gases or liquid propellants, that mixes with the formulation to create a foam or whipped cream consistency upon application, enhancing ease of application, spreading, and absorption while maintaining a non-greasy feel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional skincare and sunscreen products are used, then skin protection function is provided, but the products have a greasy texture that makes them difficult to apply and spread
Solution Approach 1:
The patent changes the physical state and delivery form of the skincare formulation from conventional liquid or cream to pressurized foam. This parameter change enables the product to be dispensed as a light, airy foam that applies easily without greasy residue, directly resolving the contradiction between ease of application and greasy texture
Solution Approach 2:
The patent utilizes phase transition by incorporating propellants that transition from liquid to gas state upon pressurization, creating a foam structure. This phase transition allows the formulation to deliver active ingredients in a foam form that spreads easily and absorbs quickly, eliminating the greasy feel while maintaining skin protection functionality
2Reliability
If conventional skincare formulations are used, then skin protection is provided, but the greasy feel leads to poor user compliance with reapplication recommendations
Solution Approach 1:
By changing the delivery system to pressurized foam, the patent creates a product with superior sensory attributes (light, non-greasy feel) that users are more likely to accept and reapply. This parameter change directly addresses the compliance issue by eliminating the greasy feel that discourages reapplication
Solution Approach 2:
The foam formulation provides self-service benefits through its unique texture and rapid absorption properties. The product automatically feels pleasant upon application without requiring additional steps, making users more likely to comply with reapplication recommendations for maintaining skin protection
3Productivity
If conventional sunscreen formulations are used, then UV protection is provided, but the products are difficult to spread and absorb slowly
Solution Approach 1:
The patent employs phase transition of propellants from liquid to gas to create a foam structure that inherently spreads rapidly. The foam's air-filled structure allows it to cover large skin areas quickly and absorb faster than conventional formulations, directly improving productivity in terms of spreading speed while eliminating the difficulty of application
4Object-generated harmful factors
If conventional lotion formulations are used, then skin moisturization is provided, but the products leave a greasy residue on the skin
Solution Approach 1:
The patent changes the physical delivery form from conventional liquid lotion to pressurized foam, which inherently reduces residue. The foam structure allows for more efficient delivery of moisturizing ingredients with less overall product needed, and the rapid absorption characteristics minimize greasy residue on the skin surface
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 formulation allows for easy, quick, and smooth application, reducing the greasy residue and improving user compliance by providing a desirable skin feel, thus enhancing skin protection and sun protection factor (SPF) efficacy.
Implementation Method 1
The pressure generating vehicle is present in the device in sufficient amounts and pressure to mix with the ejecting formulation to form a foam, whipped cream or similar form or consistency
Data Source
AI summary
In one aspect, the present invention is directed to formulations comprising at least one pressure generating vehicle along with at least one skincare active agent in a container such that the pressure generating vehicle would eject the formulation as foam, whipped cream or a similar form upon application of external pressure on the container.
