Acidic Bonding Hair Composition for Single-Step Repair and Toning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face challenges with damaged hair and brassiness after using lightening agents, requiring multiple steps and professional treatments for bond repair and color toning, which are inefficient and expensive.
Innovation Solution
A hair refreshing composition combining an acidic bonding restorative base with a color toning system, including direct dyes like violet toned EXT. VIOLET 2, anionic surfactants, esters, cationic compounds, and additional surfactants, providing a single-step solution for restoring and color toning lightened hair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple step treatments are used for bond repair and color toning, then effectiveness of repair and toning is improved, but treatment time and cost increase
Solution Approach 1:
The patent combines bond repairing composition and color toning composition into a single unified composition. The composition contains both bond repairing agents (such as cysteamine, glycerol monistearate) and color toning agents (such as violet direct dyes) in compatible formulations, allowing simultaneous application for both bond repair and brassiness neutralization in one step rather than requiring sequential separate treatments
2Device complexity
If bonding and toning compositions are mixed directly, then treatment steps are reduced, but effectiveness of bonding and toning is diminished due to incompatibility
Solution Approach 1:
The patent modifies the formulation parameters of both bond repairing and color toning components to ensure compatibility. Specific pH ranges (5.0-7.0), surfactant concentrations, and ingredient ratios are optimized so that the combined composition maintains the efficacy of both bonding agents and toning agents without mutual interference, enabling effective single-step treatment
3Productivity
If a single step composition is created, then treatment efficiency is improved, but stability and aesthetic properties may be compromised
Solution Approach 1:
The patent uses surfactants and chelating agents as intermediary components that mediate between the bond repairing agents and color toning agents. These intermediaries ensure proper mixing, distribution, and stability of the combined composition during storage and application, preventing phase separation and maintaining aesthetic properties while enabling efficient single-step treatment
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively repairs hair texture, neutralizes brassiness, and provides excellent color refreshing benefits, achieving desired cosmetic shades in just 5 minutes with stability over time and temperature.
Implementation Method 1
bonding repairing treatments are used to neutralize the damage to hair
Implementation Method 2
to neutralize brassiness, toning compositions can be applied

AI summary
A hair refreshing composition that accomplishes neutralizing and/or toning in 5 minutes and includes a color toning system with least one violet toned direct dye, and an acidic bonding restorative base that includes least one anionic surfactant including an isethionate surfactant, at least one ester including coco-caprylate/caprate, at least one cationic compound, at least one additional surfactant, and a cosmetically acceptable solvent that includes water. The composition confers the dual benefits of restoring hair texture and toning and/or neutralizing hair color, particularly in lightened or color lifted blonde hair in a formulation that is stable (retention of viscosity, bulk tone and efficacy of toning/neutralizing brassiness).
