D-aspartic Acid Antioxidant Composition for Skin Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antioxidant compositions, such as those using ascorbic acid and α-tocopherol, are not stable enough for routine use in cosmetic and pharmaceutical products, necessitating the development of a more stable and safe antioxidant solution.
Innovation Solution
D-aspartic acid, its esters, or salts are used as antioxidants in external skin preparations and food compositions to address skin conditions caused by reactive oxygen species, including fine wrinkles, dry skin, skin cancer, skin allergies, and photosensitive dermatosis, with D-aspartic acid demonstrating antioxidant effects at concentrations of 0.1 µM to 10 µM.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antioxidants like ascorbic acid and α-tocopherol are used in cosmetic and pharmaceutical products, then antioxidant effect is achieved, but stability is insufficient
Solution Approach 1:
The patent changes the chemical parameter from conventional antioxidants (ascorbic acid, α-tocopherol) to D-aspartic acid, which has superior stability properties. This parameter substitution resolves the contradiction by maintaining antioxidant efficacy while achieving the required stability for routine product use.
2Object-affected harmful factors
If D-aspartic acid is used as antioxidant in skin preparations, then oxidative damages are suppressed, but safety and stability must be ensured for routine use
Solution Approach 1:
The patent employs D-aspartic acid as a stable, safe antioxidant that can be used routinely in cosmetic and pharmaceutical products. The substance provides reliable antioxidant protection without the stability issues of conventional antioxidants, enabling its use in stable formulations for long-term product shelf life and routine application.
