Transparent Alcohol Sunscreen Spray With High UVA Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transparent alcoholic sunscreen sprays face challenges in achieving high sun protection factors and UVA protection without the use of film-forming polymers and octocrylene, which are potentially harmful, and often result in a sticky film.
Innovation Solution
A cosmetic sunscreen composition comprising phenylbenzimidazolesulfonate, ethyl alcohol, and other cosmetically acceptable oils, without octocrylene and film-forming polymers, providing high sun protection factor and UVA protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If film-forming polymers and octocrylene are used to achieve high sun protection factor and UVA protection, then the protective effect is improved, but the stickiness and harmfulness increase
Solution Approach 1:
The invention extracts and removes the harmful components (film-forming polymers and octocrylene) from the sunscreen formulation while retaining the essential sun protection function through alternative safe ingredients
Solution Approach 2:
The invention converts the formulation approach by using alcohol-based solutions with alternative UV filters that naturally provide high protection without the harmful sticky film-forming properties of conventional ingredients
2Ease of operation
If transparent alcoholic spray formulation is used to reduce stickiness, then the ease of operation is improved, but the ability to achieve high sun protection factor and UVA protection deteriorates
Solution Approach 1:
The invention changes the concentration parameters of UV filters and alcohol content to achieve the optimal balance between transparency, ease of application, and high sun protection factor with UVA protection of at least 18
Solution Approach 2:
The invention uses a composite formulation combining multiple oil-sol UV filters including avobenzone, ethylhexyl salicylate, and other approved filters to achieve synergistic high protection levels while maintaining the transparent alcoholic spray characteristics
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 achieves a high sun protection factor with stable UVA protection, maintaining transparency and avoiding stickiness, while being free of harmful ingredients.
Implementation Method 1
the UV filter phenylbenzimidazolesulfonate... achieving high sun protection factors while simultaneously providing high to very high UVA protection
Implementation Method 2
The stickiness often criticized by users in sunscreen products is therefore significantly reduced with this application method
