Amphipterygium adstringens Extract for UV Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sun protection methods, including chemical and physical sunscreens, lack effective natural alternatives that provide long-lasting protection against UV radiation-induced skin lesions and cancer, with existing plant extracts not fully utilizing their potential due to rudimentary application methods and limited absorption capabilities.
Innovation Solution
A colloidal hydroalcoholic concentrate extract of Amphipterygium adstringens bark and leaves with 12-36% w/w tannins, combined with a high molecular weight acrylic acid polymer and other ingredients, is used to create a topical composition that absorbs UV radiation and provides photoprotective, moisturizing, and healing properties for the prevention and treatment of skin lesions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If plant extracts are used as natural sun protection alternatives, then safety and naturalness are improved, but protection effectiveness and longevity are insufficient
Solution Approach 1:
The patent combines multiple plant extracts (amphipterygium adstringens, aloe vera, and others) with specific polymers and active ingredients to create a composite formulation that enhances UV protection effectiveness while maintaining natural safety, resolving the contradiction between naturalness and protection reliability
Solution Approach 2:
The patent modifies the concentration parameters of active ingredients (standardized extract ranges) and incorporates specific polymer molecular weights to optimize both the effectiveness and duration of sun protection, transforming insufficient natural protection into reliable long-lasting protection
2Manufacturing precision
If standardized extracts with specific tannin content are used, then manufacturing precision is improved, but production complexity increases
Solution Approach 1:
The patent establishes specific parameter ranges for tannin content (12-36% w/w) and extract concentrations to standardize the product quality, making the manufacturing process more precise and controllable despite the added complexity of standardization requirements
3Ease of operation
If existing plant extracts are applied in rudimentary ways, then ease of operation is maintained, but absorption capability and effectiveness are limited
Solution Approach 1:
The patent formulates a composite composition that enhances the absorption and penetration capabilities of plant extracts into the skin while maintaining simple topical application methods, resolving the contradiction between ease of use and effectiveness
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 absorbs UV radiation, offering a natural alternative to chemical sunscreens, enhancing skin protection and healing while being non-toxic and safe for human use, thus addressing the limitations of existing natural extracts in providing comprehensive sun protection.

AI summary
In general, the present invention relates to the production of extracts of plants for use in the field of sun protection, specifically to production of standardized extracts of the Mexican plant known as "Cuachalalate" (Amphipterygium adstringens) and, more particularly, the production of standardized extracts of the bark and leaves of Amphipterygium adstringens, with a view to producing a photo-absorbent phytocomplex capable of absorbing radiation in a range from 190 to 300 nm, which comprises the ultraviolet region, particularly the UVB and UVC regions; furthermore, given the proven innocuous nature thereof, said substance may be used as an ingredient in formulations not only for preventing but also for treating induced skin lesions of different etiology, including those caused by overexposure to solar radiation, and also for protecting the hair and scalp against the harmful effects of the sun's ultraviolet radiation.
