Liquid Detergent Pearlescent Agent Light Refraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Light-sensitive ingredients in liquid cleaning compositions are destabilized by packaging in transparent or translucent containers, leading to potential degradation and loss of product stability and performance over time.
Innovation Solution
A liquid detergent composition comprising greater than 5% anionic surfactant, less than 25% nonionic surfactant, and an inorganic pearlescent agent, which enhances the stability of light-sensitive ingredients and maintains aesthetic appeal by incorporating a pearlescent agent that refracts light, thereby reducing light transmission and minimizing degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the composition is packaged in a transparent or translucent package to display aesthetics, then the visual appeal is improved, but the light-sensitive ingredients are destabilized by light exposure
Solution Approach 1:
The pearlescent agent acts as an intermediary substance between light and the light-sensitive ingredients. It refracts and scatters light within the composition, reducing the amount of light that reaches the sensitive ingredients while still allowing the package to appear transparent or translucent from the outside.
Solution Approach 2:
The invention changes the optical parameters of the composition by adding pearlescent agents that alter light transmission properties. This modifies the refractive index and light scattering characteristics of the liquid composition, creating a protective effect against light penetration while maintaining aesthetic transparency.
2Reliability
If light-sensitive ingredients are protected from light exposure, then their stability is improved, but the aesthetic appeal of transparent packaging is reduced
Solution Approach 1:
The pearlescent agent serves as a mediating substance that simultaneously achieves two opposing goals: it protects light-sensitive ingredients by refracting light, while also contributing to the aesthetic appearance by creating an iridescent, pearlescent effect that enhances the visual appeal of the transparent packaging.
3Quantity of substance
If the composition remains in storage for extended periods, then shelf life is extended, but light-sensitive ingredients degrade over time due to cumulative light exposure
Solution Approach 1:
The pearlescent agents are incorporated into the composition in advance to create a built-in light protection system. This preliminary protective action is already in place during storage, preventing cumulative light damage to light-sensitive ingredients over extended shelf life periods without requiring additional protective measures.
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 stabilizes light-sensitive ingredients, maintaining product performance and aesthetics by reducing light exposure, even when packaged in transparent or translucent containers, thus extending shelf life and ensuring consistent cleaning efficacy.
Implementation Method 1
compositions comprising optical modifiers that are capable of refracting light such that the compositions appear pearlescent
