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. 11,857,654.

Summary of the Inventive Concept

An improved oral composition containing nanohydroxyapatite (NHAP) with enhanced shelf life, stability, and efficacy for better oral care.

Background and Problem Solved

The original patent (NHAP containing oral composition) had limitations in terms of shelf life, stability, and efficacy. The present inventive concept addresses these limitations by introducing improvements in the composition's formulation, pH adjustment, and bioactive agents to enhance the oral care experience.

Detailed Description of the Inventive Concept

The new inventive concept comprises a nanohydroxyapatite-based composition with an improved shelf life of at least 5 years, achieved by optimizing the pH range (7-9) and reducing the amount of sodium bicarbonate. The composition's stability is enhanced by adding a pH-adjusting agent, and its efficacy is improved by incorporating a bioactive agent to promote remineralization of tooth enamel. The NHAP suspension stock has a higher concentration of 20-30% by weight, ensuring better oral care outcomes.

Novelty and Inventive Step

The new claims introduce novel features such as extended shelf life, pH adjustment, and bioactive agents, which are not present in the original patent. These features provide a non-obvious solution to the limitations of the original patent, making the new inventive concept a significant improvement.

Alternative Embodiments and Variations

Alternative embodiments may include varying the pH-adjusting agent, using different bioactive agents, or modifying the NHAP suspension stock concentration. Variations could also involve incorporating additional ingredients to enhance the composition's cosmetic benefits or using different delivery forms, such as mouthwashes or oral rinses.

Potential Commercial Applications and Market

The enhanced NHAP containing oral composition has significant commercial potential in the oral care industry, particularly in the development of toothpastes, mouthwashes, and other oral care products. The target market includes consumers seeking improved oral care solutions with enhanced shelf life, stability, and efficacy.
