Silanated Glass Flakes for Non-Dental Applications
Legal Citation
Summary of the Inventive Concept
The inventive concept applies the core technology of silanated glass flakes to various non-dental industries, including cosmetics, pharmaceuticals, and wound care, providing improved texture, elasticity, strength, and healing properties.
Background and Problem Solved
The original patent focused on dental compositions with silanated glass flakes for improved esthetic appearance and gloss retention. However, the unique properties of silanated glass flakes can be leveraged in other fields, where current solutions lack the desired performance. This inventive concept addresses the need for innovative materials in these industries.
Detailed Description of the Inventive Concept
The inventive concept involves the use of silanated glass flakes with an average thickness between 50 nm and 1000 nm in various non-dental applications. In cosmetics, the silanated glass flakes can be incorporated into topical compositions for improved skin texture and appearance. In pharmaceuticals, they can be used as a carrier for therapeutic agents to treat bone disorders, promoting improved bone density and strength. In wound care, the silanated glass flakes can be integrated into biocompatible matrices to enhance wound healing. The silanated glass flakes provide a unique combination of properties, including improved strength, elasticity, and texture, making them an ideal material for these applications.
Novelty and Inventive Step
The new claims introduce a novel application of silanated glass flakes in non-dental industries, which is not obvious from the original patent. The inventive step lies in recognizing the potential of silanated glass flakes to solve specific problems in these industries and developing new compositions and methods that leverage their unique properties.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include the use of silanated glass flakes in other cosmetic products, such as hair care or makeup, or in pharmaceutical applications for treating other diseases or disorders. Variations of the inventive concept could also involve the development of new methods for silanating glass flakes or creating composite materials with silanated glass flakes and other components.
Potential Commercial Applications and Market
The inventive concept has significant commercial potential in the cosmetics, pharmaceuticals, and wound care industries, where there is a growing demand for innovative materials with improved performance. The target market includes companies developing topical compositions, pharmaceutical products, and wound dressing materials, as well as researchers and clinicians seeking new solutions for various health and beauty applications.
