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

This inventive concept presents improved hair coloring compositions and methods that overcome the limitations of the original patent by incorporating pH adjusters, moisturizing agents, and heat treatments to achieve better color deposition, hair protection, and user experience.

Background and Problem Solved

The original patent, 'Hair coloring compositions and methods thereof', has limitations in terms of color consistency, hair damage, and user convenience. The new inventive concept addresses these limitations by introducing pH adjusters to optimize color deposition, moisturizing agents to protect hair, and heat treatments to enhance color penetration.

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 surfactant. The compositions may further include pH adjusters selected from citric acid, lactic acid, and glycolic acid to achieve optimal pH for color deposition. Additionally, the compositions may include moisturizing agents such as glycerin, panthenol, and argania spinosa kernel oil to protect hair from damage. The methods of coloring hair involve applying the hair coloring composition to the hair, followed by rinsing with a shampoo formulation comprising a moisturizing agent. The methods may also involve applying a heat treatment to the hair after applying the hair coloring composition to enhance color penetration.

Novelty and Inventive Step

The new claims introduce pH adjusters and moisturizing agents, which are not present in the original patent. The combination of these components with the monosaccharides and surfactant provides a novel and non-obvious solution to the problems of color consistency and hair damage.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include using different types of pH adjusters, moisturizing agents, and heat treatments. For example, the pH adjusters could be replaced with other acidic or basic compounds, and the moisturizing agents could be substituted with other hair-protecting ingredients. Additionally, the heat treatments could be modified to use different temperatures, durations, or techniques.

Potential Commercial Applications and Market

The enhanced hair coloring compositions and methods have significant commercial potential in the hair care industry, particularly in the markets for at-home hair coloring kits and professional hair coloring services. The inventive concept's ability to provide better color deposition, hair protection, and user experience can differentiate products and services in a crowded market, attracting consumers seeking high-quality hair coloring solutions.

Field of Art

Cosmetic Chemistry, specifically hair coloration compositions and methods, involving organic chemistry, surfactant formulations, and topical application technologies

Person of Ordinary Skill (PHOSITA) Profile

A professional with a Bachelor's or Master's degree in chemistry, biochemistry, or cosmetic science, with expertise in formulation development, understanding of monosaccharide interactions, surfactant chemistry, and hair treatment methodologies

Obviousness Rationale

A PHOSITA would recognize that the PTD's additions of pH adjusters, moisturizing agents, and heat treatment techniques represent predictable variations to the source patent's hair coloring composition. These modifications address known challenges in hair coloration such as color consistency, hair protection, and penetration, using standard techniques within the cosmetic chemistry domain. The incremental improvements demonstrate standard problem-solving approaches a skilled practitioner would employ to optimize hair coloring formulations.

Obvious Combinations & Variations

Source Patent Element
Hair coloring composition with monosaccharides and surfactants
PTD Variation
Adding pH adjusters like citric acid, lactic acid to control composition pH
Obviousness Reasoning
Adjusting pH is a known technique in cosmetic formulations to optimize chemical interactions and product performance, representing a predictable solution for enhancing color deposition
Source Patent Element
Basic hair coloring method using monosaccharide composition
PTD Variation
Incorporating moisturizing agents like glycerin and panthenol to protect hair during coloration
Obviousness Reasoning

PTD Variation
Adding heat treatment techniques like blow drying or flat ironing to enhance color penetration
Obviousness Reasoning
Applying controlled heat to improve chemical penetration is a well-established technique in hair treatment technologies, representing an obvious optimization strategy
Source Patent Element
Surfactant-based hair coloring composition
PTD Variation
Developing a comprehensive hair coloring kit with separate developer composition containing alternative pH adjusters
Obviousness Reasoning
Creating modular hair coloration systems with interchangeable components is a standard approach in cosmetic product development, demonstrating predictable innovation
Source Patent Element
Monosaccharide hair coloring composition with specific concentration ranges
PTD Variation
Expanding composition to include precise percentages of moisturizing agents alongside existing ingredients
Obviousness Reasoning
