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. 11,857,661.

Summary of the Inventive Concept

The inventive concept leverages the antimicrobial properties of punicalagin and monoterpenoid compositions to inhibit microbial growth in various industries, including food preservation, cut flower freshness, medical device coatings, contact lens care, and surface sanitization in public places.

Background and Problem Solved

The original patent focused on anti-dandruff compositions, but the antimicrobial properties of the punicalagin and monoterpenoid compositions have broader applications. The new inventive concept addresses the need for effective microbial growth inhibition in diverse industries, where current solutions may be inadequate or have limitations.

Detailed Description of the Inventive Concept

The inventive concept comprises a system or method utilizing a punicalagin composition, a first monoterpenoid composition comprising p-cymene, and a second monoterpenoid composition comprising menthol. These compositions are applied in effective amounts to inhibit microbial growth on food products, cut flowers, medical devices, contact lenses, and surfaces in public places. The punicalagin composition may be derived from pomegranate rind extraction and have a polyphenol content of at least 30 gallic acid equivalents (GAE) on a dry weight basis.

Novelty and Inventive Step

The new inventive concept is novel and non-obvious as it applies the antimicrobial properties of punicalagin and monoterpenoid compositions to entirely new industries and use cases, which were not originally considered in the original patent. The inventive concept's novelty lies in the unexpected application of these compositions to inhibit microbial growth in diverse contexts.

Alternative Embodiments and Variations

Alternative embodiments may include varying the ratio of punicalagin to monoterpenoid compositions, using different extraction methods for the punicalagin composition, or incorporating additional antimicrobial agents. Variations may also include adapting the system or method for specific industries, such as adjusting the concentration of the compositions or modifying the application process.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including food preservation, floriculture, medical devices, contact lens care, and surface sanitization in public places. The market for microbial growth inhibition solutions is substantial, and the inventive concept's broad applicability and effectiveness position it for significant market share and revenue growth.
