Mousse Makeup Setting Composition Film Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Long-wear or extended wear makeup products do not form a durable, continuous protective film on keratinous substrates, such as skin, after application, limiting their ability to maintain the appearance of makeup.
Innovation Solution
A makeup setting composition in the form of a mousse or foam, comprising a gas phase dispersed in a condensed phase with a water-soluble or water-dispersible film former, applied to the skin and sheared to form a layer, providing a Surface Tension Value of less than 63 mN/m and being substantially free of surfactants, to create a stable and transfer-resistant film.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a makeup setting spray is used to protect applied makeup, then some protection is provided, but a durable continuous protective film cannot be formed
Solution Approach 1:
The patent changes the physical state parameter of the setting composition from a liquid spray to a foam/mousse form. This parameter change allows the composition to deposit more uniformly and form a continuous protective film, resolving the contradiction between providing protection and forming a durable continuous film.
Solution Approach 2:
The patent uses a composite foam structure consisting of gas bubbles dispersed in a liquid matrix containing film-forming polymers. This composite material approach enables both the protective function and the continuous film formation by combining the benefits of foam delivery system with film-forming polymers.
2Reliability
If conventional makeup setting products are used, then makeup protection is provided, but the application experience is less pleasant compared to foam form
Solution Approach 1:
The patent changes the physical form parameter from liquid spray to foam, which provides a more pleasant user experience through better sensory characteristics while maintaining the makeup protection function.
Solution Approach 2:
The patent utilizes the foam structure (gas dispersed in liquid) to improve ease of operation. The foam form provides better tactile feedback and application characteristics, enhancing user experience while delivering the same protective function.
3Duration of action of stationary object
If long-wear makeup products are used, then extended wear is achieved, but a durable continuous protective film is not formed
Solution Approach 1:
The patent employs a composite foam composition containing film-forming polymers dispersed in an aqueous phase. This composite structure enables the formation of a continuous protective film that maintains makeup appearance, resolving the contradiction between extended wear duration and film continuity.
Solution Approach 2:
The patent utilizes film-forming polymers that create a flexible continuous film over the makeup. This thin film structure provides both the durability needed for extended wear and the continuity required to protect makeup appearance throughout the wear period.
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 composition effectively sets and protects previously applied makeup, enhancing its durability and resistance to transfer, while maintaining a pleasant user experience and providing long-lasting foam stability.
Implementation Method 1
a makeup setting composition in the form of a mousse or foam, comprising a gas phase dispersed in a condensed phase
Implementation Method 2
It is presumed that the water evaporates leaving behind protective polymer
Implementation Method 3
shearing the makeup setting composition across the keratinous substrate to form a layer thereon
