Defibrillated Cellulose Microfibrils with Polyols for Low-Shear Redispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Defibrillated primary cell wall material with cellulose microfibrils, having a degree of crystallinity less than 50%, loses structuring properties when dried, requiring high-shear treatment to recover functionality in aqueous media, which is costly and limits its use in shear-sensitive products.
Innovation Solution
Incorporating polyols between the cellulose microfibrils allows for the recovery of structuring properties under low-shear mixing, enabling the use of dry defibrillated primary cell wall material in hair cleansing compositions without additional co-additives, thus reducing energy and cost requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If defibrillated primary cell wall material is dried to reduce bulk and transport energy, then storage and transport efficiency improve, but the material loses structuring properties and requires high-shear treatment to recover functionality
Solution Approach 1:
The patent applies preliminary action by incorporating polyols into the defibrillated primary cell wall material before drying. This pre-treatment ensures that when the material is later reconstituted in aqueous media, the polyols facilitate rapid redispersion and recovery of structuring properties without requiring high-shear treatment, thus preserving functionality while enabling dry storage and transport.
Solution Approach 2:
The patent uses polyols as an intermediary substance that mediates between the dried cell wall material and aqueous media. The polyols act as a bridge that enables the dried material to redisperse and regain its structuring properties under low-shear conditions, eliminating the need for high-shear equipment while maintaining reliability of the structuring function.

4Ease of operation
If co-additives are used to improve dispersibility of dry defibrillated primary cell wall material, then dispersibility improves, but ingredient list complexity increases and consumer acceptance decreases
Solution Approach 1:
The patent applies self-service by using polyols that are already present in or can be easily incorporated into hair care formulations. These polyols self-organize around the cell wall material during low-shear mixing, enabling dispersibility and recovery of structuring properties without requiring additional specialized co-additives, thus keeping the ingredient list simple and consumer-friendly.
