Solution Overview
Problem
Formulating hair care compositions that include beneficial electrolytes for conditioning and repairing hair while maintaining stability and consumer preferences, such as viscosity and long-term non-separation, is challenging due to the instability caused by these electrolytes.
Innovation Solution
A synergistic combination of starch polymers, cationic polymers, and fatty alcohols is used to stabilize compositions for treating keratinous substrates, including hair, by incorporating at least one electrolyte, with specific ratios of starch polymers and cationic polymers, and the presence of fatty alcohols to maintain stability and cosmetic benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrolytes are added to hair care compositions to provide conditioning and repair benefits, then the therapeutic effectiveness is improved, but the composition stability deteriorates causing phase separation
Solution Approach 1:
The patent introduces a stabilizing system comprising starch polymer, cationic polymer, and fatty alcohol as intermediary components that mediate between the electrolyte (therapeutic agent) and the composition matrix. This stabilizing system prevents direct destabilizing interactions between electrolytes and other formulation components, allowing electrolytes to remain effective while maintaining overall composition stability over time
Solution Approach 2:
The patent creates a composite formulation system by combining multiple functional components: electrolyte (for conditioning), starch polymer (for stability), cationic polymer (for hair care benefits), and fatty alcohol (for texture and stability). This composite approach allows each component to contribute its specific function while the overall system achieves both therapeutic effectiveness and long-term stability
2Reliability
If electrolytes are included in hair treatment compositions to repair damaged hair, then the therapeutic benefits are enhanced, but the viscosity control and aesthetic quality deteriorate
Solution Approach 1:
The patent utilizes the stabilizing system to modify the physical parameters of the composition, specifically viscosity and texture. The starch polymer, cationic polymer, and fatty alcohol work together to control flow properties and aesthetic characteristics, allowing the formulation to maintain desirable application properties even in the presence of electrolytes that would otherwise disrupt viscosity control
3Duration of action of stationary object
If electrolytes are added to provide long-term hair conditioning, then the duration of beneficial effect is improved, but the composition undergoes phase separation over time
Solution Approach 1:
The stabilizing system acts as a preventive measure incorporated into the formulation from the outset. The starch polymer, cationic polymer, and fatty alcohol are included beforehand to cushion against potential phase separation that would otherwise occur during storage. This preemptive stabilization allows the composition to maintain homogeneity and prevent separation over extended periods, ensuring both long-term effectiveness and physical stability
