How to compare rheology additives: the example of nanocellulose/Cellulose fibrils and HEUR

By Mats Hjørnevik 16. October 2018

As a researcher, to have an overview of the alternatives available in your area of profession is of importance. In the landscape of rheology, new alternatives are emerging. In my short review today, I will grasp on the subject of similarities and potential synergies between two of the candidates you should note down: nanocellulose and hydrophobically modified ethoxylated polyurethanes (HEUR). Here are my hints and tips  on how to understand these two technologies better.

Montmorillonite Clay (Bentonites) and cellulose fibrils

By Mats Hjørnevik 21. November 2017

Montmorillonite (Bentonite) clay and cellulose fibrils has a lot in common since they both can be used as a rheology modifier in different industries. However, there are also clear distinct differences. I aim to show you how I reflect on these two product technologies, and how you can look for synergies and new innovations when using cellulose fibrils and clay. I will first review the non-soluble nature which is common for these materials and then show how this is reflected in the rheology and stability properties of each. I will also focus my discussion on the bentonite branch of montmorillonite clays due to its similarities with the cellulose fibrils

MFC in cleaners - how to thicken your advanced cleaning products

By Otto Soidinsalo 12. September 2017

Many household and industrial cleaners are strongly alkaline, highly acidic or contain oxidizing agents. This creates challenges when one would like thicken them or to have a gel formulation instead of the corresponding thin liquid version. In many cases, viscous, gel or foam formulations are preferred, as they ensure longer residence time on the vertical surfaces and are also safer to use as they are good at preventing any unwanted splashing. Today we will look at how MFC allows you to manufacture stable gel formulations at low to high pH as well as with oxidizing compounds, such as hydrogen peroxide.
