Solution Overview
Problem
Current hair styling compositions often fail to provide sufficient shine and smoothness to human hair, with existing products either lacking in shine or experiencing insufficient smoothness after drying.
Innovation Solution
A cosmetic hair styling composition comprising Polyquaternium-4, Polyquaternium-37, and C12-15 Alkyl Benzoate, formulated as an O/W-emulsion with specific viscosity and nitrogen content ranges, and optionally including a water-insoluble silicone compound and cationic surfactant, to enhance shine and smoothness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional hair styling compositions are used, then basic styling functions are achieved, but sufficient shine and smoothness are not provided
Solution Approach 1:
The patent applies composite materials by combining three specific polymers (Polyquaternium-4, Polyquaternium-37, and C12-15 Alkyl Benzoate) in a specific formulation. This composite approach creates a synergistic effect where the combination of materials provides both shine and smoothness properties that individual materials cannot achieve alone, directly resolving the technical contradiction between achieving shine and maintaining smoothness after drying.
Solution Approach 2:
The patent utilizes parameter changes by carefully controlling the viscosity range (20-400 cP) and nitrogen content (1.5-3% by weight) of the polymer composition. These parameter optimizations enable the formulation to deliver both aesthetic shine and functional smoothness, transforming the product performance to simultaneously achieve both desirable properties without compromise.
2Reliability
If hair styling compositions provide basic styling functions, then hair positioning is achieved, but shine and smoothness properties are insufficient
Solution Approach 1:
The formulation combines Polyquaternium-4, Polyquaternium-37, and C12-15 Alkyl Benzoate in specific proportions to create a composite material system. This composite approach ensures that the product reliably provides smoothness after drying while simultaneously delivering shine, as the synergistic interaction between components addresses both properties together rather than prioritizing one over the other.
Solution Approach 2:
By optimizing the viscosity parameter to 20-400 cP and nitrogen content to 1.5-3% by weight, the patent achieves a formulation that maintains smoothness reliability after drying while enhancing shine. These parameter adjustments are critical to resolving the contradiction by enabling both properties to coexist at high levels.
3Strength
If styling polymers are used for inter-fiber adhesion, then hair positioning is improved, but shine and smoothness are not sufficiently enhanced
Solution Approach 1:
The patent employs a composite polymer system where Polyquaternium-4, Polyquaternium-37, and C12-15 Alkyl Benzoate work together to provide both mechanical strength for inter-fiber adhesion and optical properties for shine. The composite formulation ensures that strengthening adhesion does not compromise shine, as the materials contribute multiple functions simultaneously.
Solution Approach 2:
The polymer composition exhibits multi-functionality by simultaneously providing inter-fiber adhesion, shine, and smoothness. This universal approach allows a single formulation to address multiple hair styling requirements, including mechanical bonding strength and aesthetic appearance, without requiring separate products for each function.
4Strength
If existing hair styling products are used, then basic styling effects are achieved, but smoothness after drying is insufficient
Solution Approach 1:
The composite formulation of three polymers creates a system where hold strength and post-drying smoothness are achieved together. The interaction between Polyquaternium-4, Polyquaternium-37, and C12-15 Alkyl Benzoate ensures that the product maintains its holding capability while delivering reliable smoothness after the hair dries, resolving the contradiction between these two properties.
Solution Approach 2:
By controlling the viscosity within 20-400 cP and nitrogen content at 1.5-3% by weight, the patent optimizes the formulation to maintain hold strength while ensuring smoothness after drying. These parameter specifications are critical to achieving the dual performance of mechanical holding and aesthetic smoothness simultaneously.
