This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,658.

Summary of the Inventive Concept

A novel cosmetic composition system that combines synergistic film formers and skin adhesion promoters to provide durable, transfer-resistant, and comfortable wear with improved color retention and water resistance.

Background and Problem Solved

Traditional cosmetic compositions often compromise on color intensity, water resistance, and skin feel. The original patent addressed these limitations by introducing a cosmetic composition with enhanced color retention and water resistance. However, there remains a need for further improvements to overcome the inherent limitations of the existing patent, such as the need for better film former and skin adhesion promoter combinations to achieve optimal performance. The new inventive concept addresses these limitations by introducing a synergistic combination of film formers and skin adhesion promoters to provide a more durable, transfer-resistant, and comfortable wear.

Detailed Description of the Inventive Concept

The new inventive concept comprises a cosmetic composition system that combines a film former, a skin adhesion promoter, a color enhancer, and one or more colorants. The film former is selected from a group consisting of acrylate/C12-22 methacrylate copolymer, PPG-17/IPDI/DMPA copolymer, and VP/polycarbamyl polyglycol ester. The skin adhesion promoter is selected from a group consisting of bis-PPG-15 dimethicone/IPDI copolymer, a mixture of polyester-7 and neopentylglycol polyester, VP/eicosene copolymer, a mixture of hydrogenated polyisobutene, butylene/ethylene/styrene copolymer, and ethylene/propylene/styrene copolymer, bis-PPG-15 dimethicone/IPDI copolymer. The color enhancer is selected from a group consisting of one or more photoactives. The composition provides a durable, transfer-resistant, and comfortable wear with improved color retention and water resistance. The synergistic combination of film formers and skin adhesion promoters enables the composition to overcome the limitations of the original patent and provide optimal performance.

Novelty and Inventive Step

The new inventive concept introduces a novel synergistic combination of film formers and skin adhesion promoters that provides a durable, transfer-resistant, and comfortable wear with improved color retention and water resistance. The combination of these components in a specific ratio and proportion is new and non-obvious compared to the original patent, providing a significant improvement over the existing art.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include varying the type and amount of film formers, skin adhesion promoters, and color enhancers to achieve different performance characteristics. Additionally, the composition may be formulated with different ratios of components to achieve specific benefits, such as improved water resistance or enhanced skin feel.

Potential Commercial Applications and Market

The new inventive concept has significant commercial potential in the cosmetic industry, particularly in the development of high-performance, multi-functional cosmetic products that provide improved color retention, water resistance, and skin feel. The target market includes consumers seeking premium, high-quality cosmetic products that provide a durable, transfer-resistant, and comfortable wear.
