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 inventive concept relates to specialized hair coloring compositions and methods adapted for specific, narrow markets or unique operational environments, such as high-security needs, disaster relief, or extreme weather conditions.

Background and Problem Solved

The original patent disclosed hair coloring compositions with specific monosaccharide and surfactant combinations. However, these compositions may not be suitable for extreme environments, where factors like high altitude, extreme temperatures, or limited resources may affect the coloring process. The new inventive concept addresses these limitations by providing specialized hair coloring compositions and methods tailored to these specific environments.

Detailed Description of the Inventive Concept

The new claims describe hair coloring compositions comprising specific monosaccharide and surfactant blends, with pH ranges and fatty acid/alcohol content tailored to extreme environments. For example, Claim 1 discloses a composition for high-altitude environments with a pH range of 2-5 and substantially free of fatty alcohols. Claim 2 describes a method for coloring hair in extreme weather conditions, involving the application of a composition with a specific surfactant blend and rinsing with water at a controlled temperature. The inventive concept also encompasses kits and systems for disaster relief and high-security environments.

Novelty and Inventive Step

The new claims introduce novel combinations of monosaccharides, surfactants, and pH ranges, which are non-obvious compared to the original patent. The inventive concept's value lies in its adaptability to specific, narrow markets or unique operational environments, providing a solution to the limitations of the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the monosaccharide and surfactant blends, pH ranges, and fatty acid/alcohol content to accommodate different extreme environments. For example, a composition for extreme cold temperatures could incorporate additional moisturizing agents, while a composition for high-humidity environments could include anti-frizz agents.

Potential Commercial Applications and Market

The inventive concept has commercial potential in various industries, including the beauty and cosmetics sector, disaster relief organizations, and high-security facilities. The specialized hair coloring compositions and methods could be marketed as premium products for specific environments, offering a competitive advantage in these niche markets.
