Solution Overview

Problem

Existing hair care compositions fail to effectively condition damaged hair and are often reliant on petroleum-based silicones, which are costly and inefficient, necessitating a need for a natural, renewable conditioning active that can replace or complement silicones to provide enhanced conditioning benefits.

Innovation Solution

A hair care composition utilizing sucrose polyesters with specific melting points, iodine values, and blends thereof, combined with cationic polymers and aqueous carriers, to deliver both wet and dry conditioning benefits to damaged hair.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If silicone compounds are used as conditioning agents, then conditioning benefits are provided, but costs increase and efficiency on damaged hair decreases

Engineering Contradiction:

Improveconditioning efficiencyVSAvoidcost

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent changes the chemical parameters of the conditioning agent by using sucrose polyesters with specific melting points (greater than 30°C), iodine values (greater than 5), and iodine values (3-70) instead of traditional silicones. This parameter change provides effective conditioning on damaged hair while being derived from renewable resources, resolving the contradiction between conditioning efficiency and cost/efficiency on damaged hair.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces expensive silicone compounds with sucrose polyesters derived from renewable resources such as sugars and fatty acids. This substitution uses a more cost-effective, naturally-derived alternative that maintains conditioning benefits while reducing dependency on costly petroleum-based silicones, particularly for damaged hair conditioning.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Reliability

If traditional conditioning actives are used, then some conditioning benefit is provided, but damaged hair remains difficult to condition

Engineering Contradiction:

Improveconditioning benefitVSAvoiddamage to hair

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent employs sucrose polyesters with specifically controlled parameters (melting point >30°C, IBAR >5, IV 3-70) that provide superior conditioning for damaged hair. These parameter-specific compounds penetrate and condition damaged hair more effectively than traditional conditioning actives, directly addressing the inability of conventional products to effectively condition damaged hair.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses composite sucrose polyester materials with specific molecular structures and physical properties that combine the benefits of natural derivation with effective conditioning performance. The composite nature of these sucrose polyesters, with controlled melting points and molecular characteristics, enables them to effectively condition damaged hair where traditional single-material actives fail.
