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. 11,857,662.

Summary of the Inventive Concept

The present inventive concept relates to improved hair coloring compositions and methods that provide better color depositing properties, enhanced moisturizing capabilities, and more efficient preparation processes, while addressing the limitations of existing hair coloring technologies.

Background and Problem Solved

The original patent disclosed hair coloring compositions and methods that utilized a combination of monosaccharides and surfactants. However, these compositions had limited color depositing properties and moisturizing capabilities, and their preparation processes were often inefficient. The present inventive concept addresses these limitations by introducing new components, such as fatty acid derivatives and polyoxyalkylene derivatives, and modifying the preparation processes to achieve improved performance.

Detailed Description of the Inventive Concept

The new hair coloring compositions comprise a first monosaccharide having 2 to 4 carbon atoms, a second monosaccharide having 2 to 4 carbon atoms, and a fatty acid derivative or a polyoxyalkylene derivative. The fatty acid derivative improves the color depositing properties of the composition, while the polyoxyalkylene derivative enhances the moisturizing properties. The compositions may also include a pH adjusting agent to achieve a desired pH range. The methods of the present inventive concept involve applying the composition to the hair, allowing it to penetrate, and then rinsing it off. The preparation process involves mixing the components and adjusting the pH to achieve the desired range.

Novelty and Inventive Step

The new claims introduce novel combinations of components, such as fatty acid derivatives and polyoxyalkylene derivatives, which provide improved color depositing properties and enhanced moisturizing capabilities. The modified preparation processes also contribute to the novelty and inventive step of the present inventive concept.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include using different types of fatty acid derivatives or polyoxyalkylene derivatives, varying the concentration of these components, or incorporating additional ingredients to further enhance the performance of the compositions. The methods of the present inventive concept may also be adapted for use with different types of hair or to achieve specific hair colors.

Potential Commercial Applications and Market

The present inventive concept has significant commercial potential in the hair care industry, particularly in the development of new hair coloring products that offer improved performance and convenience. The target market includes professional hair care providers, as well as individual consumers seeking high-quality hair coloring solutions.
