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. 11,857,659.

Summary of the Inventive Concept

The inventive concept leverages the core technology of microcapsules with oil-based cores and polymeric shells coated with cationic polymers, originally designed for rinse-off conditioner compositions, to address unmet needs in agricultural crop protection, biomedical applications, cosmetic skincare products, and pharmaceuticals.

Background and Problem Solved

The original patent disclosed rinse-off conditioner compositions comprising microcapsules with oil-based cores and polymeric shells coated with cationic polymers. However, the technology's potential applications were limited to the cosmetic industry. The new inventive concept addresses the need for controlled release and targeted delivery in various industries, such as agriculture, biomedicine, and pharmaceuticals, where existing solutions often lack efficacy, safety, or sustainability.

Detailed Description of the Inventive Concept

The inventive concept involves adapting the microcapsule technology to create compositions for controlled release of pesticides, fertilizers, therapeutic agents, and active ingredients for skin protection. The microcapsules' oil-based cores and polymeric shells coated with cationic polymers enable sustained release, improved efficacy, and reduced environmental impact. The new claims encompass systems, methods, and compositions for various industries, including agricultural crop protection, biomedical applications, cosmetic skincare products, and pharmaceuticals.

Novelty and Inventive Step

The new claims introduce a novel application of the microcapsule technology, extending its use beyond the cosmetic industry to address specific needs in agriculture, biomedicine, and pharmaceuticals. The inventive step lies in recognizing the potential of this technology to solve problems in these industries and adapting it to create innovative solutions.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different types of polymers or cationic coatings, varying the size and shape of the microcapsules, or incorporating additional components to enhance the controlled release mechanism. Variations could also involve adapting the technology for use in other industries, such as food processing or textiles.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including agricultural crop protection, biomedical applications, cosmetic skincare products, and pharmaceuticals. The market for controlled release and targeted delivery solutions is substantial, with growing demand for sustainable and effective solutions. The inventive concept's potential to address unmet needs in these industries could lead to significant revenue growth and market share.
