Non-Ionic Polymer Hair Styling Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hair styling products often result in undesirable side effects such as a sticky feeling, unnatural weight-down, and impaired curl definition, particularly for curly hair, leading to unnatural-looking curls that lack natural movement.
Innovation Solution
An aqueous composition comprising organic solvents and non-ionic hair styling polymers, with a total concentration of anionic polymers at 0.2% by weight or less, is applied to keratin fibers, followed by mechanical treatment like scrunching or twisting, to enhance curl definition and maintain natural hair movement without weighing it down.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional hair styling products are used, then curl definition is improved, but hair becomes sticky and weighs down unnaturally
Solution Approach 1:
The patent removes anionic polymers from the composition entirely, extracting only the non-ionic styling polymers that provide curl definition without causing sticky feelings or unnatural weight-down. This selective extraction resolves the contradiction by eliminating the harmful components while retaining the beneficial styling effects.
Solution Approach 2:
The patent changes the chemical parameter by specifying only non-ionic styling polymers and limiting anionic polymer content to 0.2% by weight or less. This parameter change transforms the composition from one that causes sticky feelings to one that provides natural-looking curls with proper definition.
2Ease of operation
If anionic polymers are included in styling products, then styling effectiveness is improved, but curl definition properties are impaired under mechanical treatment
Solution Approach 1:
The patent extracts anionic polymers from the composition, retaining only non-ionic styling polymers. This extraction maintains styling effectiveness while preserving curl definition properties during mechanical treatment such as scrunching and twisting, as non-ionic polymers do not interfere with the natural curl structure.
Solution Approach 2:
The patent uses a composite approach by combining specific non-ionic styling polymers with organic solvents and optional cationic polymers in defined concentration ranges. This composite formulation achieves both styling effectiveness and curl definition maintenance under mechanical treatment.
3Shape
If styling products are applied to enhance curls, then curl appearance is improved, but natural movement is lost
Solution Approach 1:
The patent changes the chemical composition parameters by limiting anionic polymers to 0.2% by weight or less and using specifically formulated non-ionic polymers. This parameter change allows curls to maintain their natural movement and adaptability while still achieving improved curl appearance and definition.
Solution Approach 2:
The patent applies styling polymers in a controlled manner that enhances curl shape locally without restricting the natural movement of individual curl sections. The formulation allows each curl to move independently while maintaining overall definition and appearance.
