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. 11,857,515.

Summary of the Inventive Concept

The present disclosure pertains to the application of branched amino acid surfactants in novel industries, including agricultural pest control, industrial wastewater treatment, oil spill remediation, enhanced oil recovery, and nanostructured material fabrication, leveraging their surface-active properties to address specific challenges in these fields.

Background and Problem Solved

While the original patent disclosed branched amino acid surfactants for use in healthcare products, their potential in other industries remained unexplored. The new claims address the limitations of the original patent by applying the core technology to diverse industrial applications, where existing solutions are often inadequate or inefficient.

Detailed Description of the Inventive Concept

The branched amino acid surfactants, characterized by the formula wherein R1 and R2 are independently chosen from hydrogen, an oxygen atom, and C1-C6 alkyl, are employed in various industrial settings to enhance the delivery of pesticides, remove contaminants from wastewater, solubilize oil spills, reduce interfacial tension in enhanced oil recovery, and facilitate the fabrication of nanostructured materials. The surfactants' surface-active properties enable them to interact with and manipulate the target substances, leading to improved outcomes in these applications.

Novelty and Inventive Step

The new claims introduce a novel and non-obvious application of branched amino acid surfactants in industrial settings, departing from the original patent's focus on healthcare products. The inventive step lies in recognizing the surfactants' potential in these new fields and adapting their formulation and use to address specific challenges.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different alkyl chain lengths, varying the siloxane derivative structure, or incorporating additional functional groups to further enhance the surfactants' properties. These variations could lead to tailored solutions for specific industrial applications or improve the overall performance of the branched amino acid surfactants.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including agriculture, environmental remediation, oil and gas, and materials science. The target market includes companies and organizations seeking innovative solutions to improve their processes, reduce costs, and minimize environmental impact.
