Lutein α-Gel Cosmetic Composition for Blue-Light Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic compositions are not sufficiently effective in preventing or reducing skin photoaging caused by blue light exposure.
Innovation Solution
A cosmetic composition containing alkyl phosphate esters, basic amino acids or organic bases, and water forms an α-gel structure that enhances lutein's blue light blocking capacity without increasing lutein content, providing a stable high-water-content structure that is not sticky to the touch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cosmetic compositions containing blue light blocking ingredients (jade powder, bilberry extract) are used, then some blue light blocking effect is achieved, but the effectiveness is insufficient to adequately prevent skin photoaging
Solution Approach 1:
The invention combines lutein with a specific carrier composition containing alkyl phosphate esters (12-36 carbon atoms), basic amino acids, and water to form a composite cosmetic preparation. This composite structure enhances the blue light blocking capacity beyond what lutein alone or conventional ingredients can achieve, effectively addressing the insufficiency of prior art
Solution Approach 2:
The invention optimizes specific parameters including the carbon atom count of alkyl phosphate esters (12-36), the concentration of lutein (0.0025-0.1%), and the presence of basic amino acids to maximize blue light blocking effectiveness. These parameter optimizations transform an insufficient blocking effect into a highly effective prevention system against skin photoaging
2Reliability
If lutein content is increased to enhance blue light blocking capacity, then blocking effectiveness improves, but cosmetic texture becomes problematic (sticky)
Solution Approach 1:
The invention introduces alkyl phosphate esters and basic amino acids as intermediary substances that facilitate the incorporation of lutein into a water-based carrier system. These intermediaries enable high lutein content (up to 0.1%) to be achieved without the sticky texture problems, as they act as surfactants and structure-forming agents that maintain pleasant cosmetic texture
Solution Approach 2:
By controlling the carbon chain length of alkyl phosphate esters (12-36 atoms) and optimizing the concentration ratios of components, the invention achieves a parameter optimization that simultaneously enables high lutein content for effective blue light blocking while maintaining non-sticky, pleasant cosmetic texture
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 enhances blue light blocking capacity, reducing the impact of blue light on the skin and preventing photoaging while maintaining a pleasant texture.
Implementation Method 1
lutein's blue light blocking capacity
Implementation Method 2
an α-gel structure having a specific composition would enhance the blue light blocking capacity possessed by lutein

AI summary
An object is to provide a new cosmetic composition that can prevent or reduce skin “photoaging” caused by blue light. As a solution, a cosmetic composition is provided, which is characterized in that it contains: (a) one or more types of alkyl phosphate esters selected from alkyl phosphate esters having alkyl groups with 12 to 36 carbon atoms; (b) one or more types of substances selected from basic amino acids and organic bases; (c) water; and (d) lutein.
