Deep Eutectic Solvent Hair Compositions for Frizz Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hair care products fail to provide sustained improvements in hair manageability, strength, and frizz reduction while also offering styling and conditioning benefits without the need for frequent reapplication or heat tools.
Innovation Solution
Cosmetic compositions containing deep eutectic solvent systems, specifically formulated with citric acid and urea compounds, which diffuse into hair to form a stabilizing network, reducing frizz and enhancing hair strength and manageability without heat, and including cationic surfactants, fatty compounds, and polyols for improved texture and shine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional hair care products are used to condition hair and improve cosmetic properties, then hair smoothness and softness are improved, but the improvements are not sustained and require frequent reapplication
Solution Approach 1:
The composition performs preliminary conditioning action that penetrates into the hair shaft and forms a long-lasting protective network within the hair structure, rather than just surface deposition. This preliminary penetration action ensures sustained effects without frequent reapplication.
Solution Approach 2:
The patent uses specific parameter changes including the deep eutectic solvent system (citric acid and urea compound in specific ratios), controlled pH (3.5-5.5), and specific concentration ranges to transform the conditioning mechanism from surface-level to deep-penetrating, extending the duration of action.
2Shape
If heat tools are used to style hair and improve alignment, then hair straightness and manageability are improved, but hair strength is reduced and damage increases
Solution Approach 1:
The patent replaces the mechanical/thermal system (heat tools) with a chemical system (deep eutectic solvent composition) that achieves hair alignment through chemical interaction and network formation within the hair structure, eliminating the need for heat-induced styling.
Solution Approach 2:
The deep eutectic solvent composition acts as an intermediary substance that mediates between the hair's natural structure and the desired styled appearance, providing alignment and shape without the damaging effects of direct heat application.
3Strength
If deep eutectic solvent systems are used to reinforce hair structure and reduce frizz, then hair strength and manageability are improved, but the formulation complexity increases
Solution Approach 1:
The patent employs a composite material system consisting of citric acid and urea compound in specific ratios (1:2 to 2:1) that creates a deep eutectic solvent system. This composite approach provides enhanced hair strengthening effects while the specific ratio constraints simplify the formulation process by defining clear mixing parameters.
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 compositions provide long-lasting hair strength, reduced frizz, improved manageability, and increased shine, while allowing for styling and reshaping without heat, offering a comprehensive hair care solution.
Implementation Method 1
the cosmetic compositions, and particularly cosmetic compositions containing certain deep eutectic solvent systems, may diffuse into the hair and form an extensive network
Implementation Method 2
the cosmetic compositions may be capable of self-association typically through hydrogen bond interactions, which may enable the cosmetic compositions to reinforce and/or strengthen hair

AI summary
Cosmetic compositions, kits thereof, and methods of making and using such cosmetic compositions. The cosmetic compositions comprising about 0.1 to about 25 wt. % of citric acid, about 0.2 to about 40 wt. % of one or more urea compound, and about 20 wt. % or more water wherein all weight percentages are based on the total weight of the cosmetic composition. Additionally, the cosmetic compositions are typically formulated to have a molar ratio of the citric acid of (a) to the urea compound of (b) is 1 or less.
