Fermentation-Derived Cellulose for Silicone Deposition in Shampoos
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Synthetic rheology modifiers in cleansing systems, such as Carbomers and acrylic copolymers, negatively impact silicone deposition on hair, leading to suboptimal conditioning performance due to decreased release of silicone conditioning agents.
Innovation Solution
Incorporating fermentation-derived cellulose (FDC) and blends with other polysaccharides like xanthan gum and guar gum as thickeners/stabilizers in conditioning and cleansing compositions, which enhances silicone deposition and provides stable rheological properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If synthetic rheology modifiers (Carbomers and acrylic copolymers) are used to provide thickening and stabilization, then rheological properties are improved, but silicone deposition on hair deteriorates
Solution Approach 1:
The patent changes the chemical parameter of the rheology modifier from synthetic polymers (Carbomers, acrylic copolymers) to fermentation-derived cellulose, which has different molecular structure and surface properties that are compatible with silicone conditioning agents, thereby maintaining rheological stability while enabling proper silicone deposition
Solution Approach 2:
The patent replaces expensive synthetic rheology modifiers with fermentation-derived cellulose, a more economical and biodegradable alternative that achieves the same thickening function without the harmful interaction with silicone ingredients
2Stability of the object's composition
If synthetic rheology modifiers are used to maintain formulation stability, then composition stability is improved, but conditioning performance deteriorates due to decreased silicone release
Solution Approach 1:
The patent changes the chemical composition parameter by substituting synthetic polymers with fermentation-derived cellulose, which maintains the necessary viscosity and stability parameters while being chemically compatible with silicone conditioning agents, allowing proper release and deposition on hair
Solution Approach 2:
The patent creates a composite system where fermentation-derived cellulose works synergistically with silicone conditioning agents, combining the thickening and stabilizing function with enhanced silicone deposition capability to achieve both formulation stability and conditioning performance
