Hydroxy Functionalized Solvent Skin Composition Transparency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic compositions either rely heavily on colorants that interfere with skin appearance or use metal oxides that result in an artificial look and are difficult to apply, failing to provide both sensory and nourishing benefits while maintaining transparency and avoiding crystallization and gellation.
Innovation Solution
A cosmetic composition comprising 12-hydroxystearic acid and a hydroxy functionalized solvent, which is substantially transparent and free of water, along with optional co-solvents and skin benefit agents, to deliver anti-aging, lightening, and sensory benefits without crystallization or gellation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high loadings of colorants are used to achieve covering purpose, then skin tone matching is improved, but skin appearance becomes artificial and sensory attributes are negatively interfered with
Solution Approach 1:
The patent removes traditional colorants and metal oxides from the composition entirely, extracting the harmful covering agents that caused artificial appearance. Instead, it uses 12-hydroxystearic acid combined with hydroxy functionalized solvents to achieve skin benefits without compromising sensory attributes or creating an artificial look.
2Quantity of substance
If metal oxides like titanium dioxide are used to provide soft focus effect, then skin blemishes are hidden, but the composition becomes draggy and difficult to apply
Solution Approach 1:
The patent extracts metal oxides like titanium dioxide from the formulation, eliminating the draggy texture and application difficulties they cause. The replacement system using 12-hydroxystearic acid and hydroxy functionalized solvents provides skin benefits without compromising ease of application.
3Reliability
If conventional cosmetic compositions are formulated to provide skin benefits, then nourishing benefits are delivered, but crystallization and gellation occur
Solution Approach 1:
The patent changes the chemical parameters of the solvent system by using hydroxy functionalized solvents with specific hydroxyl group densities (0.03-0.50). This parameter change prevents crystallization and gellation of 12-hydroxystearic acid while maintaining skin nourishing benefits, achieving both reliability and compositional stability.
4Illumination intensity
If compositions are formulated to be transparent, then light transmission is improved, but stability over time is compromised due to crystallization and gellation
Solution Approach 1:
The patent modifies the solvent parameters by selecting hydroxy functionalized solvents with specific hydroxyl group densities that maintain transparency while preventing crystallization and gellation over time. This parameter optimization achieves both immediate transparency and long-term compositional stability.
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 remains transparent and effective for over three months, providing excellent sensory and skin nourishing benefits, improving skin quality and appearance without the drawbacks of crystallization or gellation, as demonstrated by its stability and positive panelist feedback.
Implementation Method 1
a cosmetic composition comprising a hydroxy functionalized solvent and 12-hydroxystearic acid. The cosmetic composition is substantially transparent (preferably transparent) and unexpectedly delivers excellent skin benefits to consumers while surprisingly remaining free of crystallization and gellation.
