Aerated Cosmetic Foam Density Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aerated cosmetic compositions for keratin materials lack stability and durability in their foam aspect, often deteriorating quickly in density, leading to unsatisfactory expansion quality and comfort during application.
Innovation Solution
An aerated cosmetic composition with a density of less than or equal to 0.12 g/cm3, formed by combining an aqueous phase and a filler in a physiologically acceptable medium, using air or inert gases to create a stable foam texture with a base composition, and a dispenser mechanism that includes a reservoir and a manual pump to maintain the desired density and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If aerated cosmetic compositions are produced with light texture and foam appearance, then the lightness and foam aspect are improved, but the stability and durability of the foam deteriorate quickly over time
Solution Approach 1:
The patent applies parameter changes by carefully controlling the density of the aerated composition to be less than or equal to 0.12 g/cm³, and by selecting specific fillers with appropriate density values. This optimization of physical parameters maintains the light foam texture while preventing excessive expansion that would compromise stability.
Solution Approach 2:
The patent uses composite materials by combining an aqueous phase with solid fillers (such as silica, titanium dioxide, zinc oxide) to create a stabilized aerated composition. The fillers provide structural support to the foam matrix, preventing collapse and maintaining foam aspect over time while contributing to the desired light texture.
2Weight of stationary object
If the density of the aerated composition is reduced to improve lightness, then the lightness is improved, but the foam quickly sags and loses its expansion quality
Solution Approach 1:
The patent optimizes the density parameter to be less than or equal to 0.12 g/cm³, which is sufficiently low to provide lightness but not so low as to compromise structural integrity. This precise parameter control resolves the contradiction between lightness and expansion quality.
Solution Approach 2:
The patent utilizes porous solid fillers that provide internal structure within the aerated composition. These porous materials maintain the foam's expansion quality by providing a scaffold that prevents collapse, even at low densities.
3Shape
If air is introduced into cosmetic compositions to create foam, then the lightness and foam appearance are improved, but the foam deteriorates very quickly in terms of density
Solution Approach 1:
The patent creates a composite system where solid fillers are dispersed in an aqueous phase containing the aerated structure. The fillers (such as silica, titanium dioxide, zinc oxide) provide long-term structural support to the foam, preventing rapid density deterioration and extending foam durability while maintaining the desired light texture.
Solution Approach 2:
The patent controls the density parameter and the concentration of fillers to optimize the balance between light texture and foam durability. By adjusting these parameters, the composition maintains its foam aspect over an extended period without rapid deterioration.
