Solution Overview

Problem

Current styling shampoos often fail to provide effective styling performance while cleaning, requiring additional products like hair wax or styling gel, and existing formulations using cationic deposition polymers are not cost-effective or flexible enough.

Innovation Solution

A styling shampoo composition comprising a cationic polymer with a charge density of 2 to 10 meq/gram, combined with at least one anionic surfactant and optionally an amphoteric or non-ionic surfactant, to enhance styling performance without the need for additional products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cationic deposition polymer and cationic styling polymer are used together to achieve styling effect, then styling performance is improved, but formulation complexity and cost increase

Engineering Contradiction:

Improvestyling performanceVSAvoidformulation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the need for separate cationic deposition polymer and cationic styling polymer by using a single cationic polymer that inherently provides both cleaning and styling functions, thereby simplifying the formulation while maintaining styling performance

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The cationic polymer is designed to perform multiple functions simultaneously - it acts as both a cleaning agent and a styling agent, eliminating the need for separate products and reducing formulation complexity while maintaining effective styling performance

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple styling products are used to meet styling needs, then styling performance is improved, but product quantity and cost increase

Engineering Contradiction:

Improvestyling performanceVSAvoidproduct quantity

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent merges the functions of multiple styling products (cleaning shampoo and leave-on styling product) into a single integrated styling shampoo composition that provides both cleaning and styling effects from one product application

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single styling shampoo composition is designed to perform multiple functions - cleaning hair and providing styling effects - thereby eliminating the need for multiple separate products and reducing overall product quantity while maintaining effective styling performance

Inventive Principle:

Principle #6Universality (Multi-functionality)
