Bring your corrugated starch adhesive robustness to a new level with Exilva MFC

26. May 2020

In a previous blog post, I explained how the new technology of Exilva microfibrillated cellulose may improve the viscosity stability of starch adhesives. Here is the second blog post in the corrugated boards application series, and now I have entered the glue kitchen of a corrugated boards manufacturer to evaluate the robustness and stability effects of Exilva.

Can Exilva be used with Quaternary ammonium compounds?

Quaternary ammonium compounds (QACs) are a group of cationic antimicrobials widely used for numerous industrial and pharmaceutical purposes. They are disinfectant chemicals commonly used in disinfectant wipes, sprays and household cleaners. They are very popular these days as they allow products to claim to be antibacterial and are part of many EPA listed products with emerging viral pathogens and human coronavirus (Covid-19) claims.

How to use Cellulose fibrils with foam forming surfactants

Surfactants are present in most consumer products. The most familiar examples are shampoos, hand wash products and cleaning products in general. Switching to sulfate free surfactants improves the environmental profile, but can be a challenge. Let me show you a way to this.

I will demonstrate that one can use cellulose fibrils to thicken and stabilize formulations with foam forming surfactants. The most important point to remember when preparing such formulations is to avoid foam formation during the incorporation step of surfactants with the cellulose fibrils.

Topic Tuesday: How to perform with your oil-in-water-emulsion

Mixing two liquids like oil and water is hard enough. At the same time keeping it stable, adds an additional level of difficulty in this challenge. And how can you reach the best performance on rheology and stability in the making of these emulsions? In this episode of Topic Tuesday, we are discussing the subject of emulsions; what are they, how do they work and how do we make them stable? Grab a coffee and joins us for a video session.

Cellulose fibrils for immediate skin anti-wrinkle effect

There are many different solutions for reducing wrinkles and age marks on the skin. These range from long term permanent treatments of the skin to formulations that have immediate, temporary and only optical effects on the skin. In most formulations and products, a combination of a permanent solution with an immediate effect is desired.

In this blog post, I will introduce the terms “anti-aging”, “anti-wrinkle effect”, “immediate anti-wrinkle effect” and follow up with a few points explaining why cellulose fibrils can potentially give an immediate skin anti-wrinkle effect.

What is the effect of MFC on emulsion stability

Have you heard the saying “Oil and water don’t mix”? This is a proverb said of things with such different natures that they cannot be combined. It is however not totally true since oil and water can be mixed into an emulsion. In many different industries such as cosmetics, pharma, paints, coatings, household products and many more, professionals mix different oils and water to create the desired performance of a product. They overcome the hurdle of “mixing” oil and water by using emulsifiers, surfactants and stabilizers. So how can MFC contribute?

Jars or spray bottles? You choose in your MFC cosmetic formulation

In many end products, and specifically in cosmetics, the first thing that attracts the consumer is the packaging format. This implies that the packaging should look good and luxurious as a sign of product performance.

There are many possible technical solutions for packaging of cosmetic products: jars, spray bottles, pumpable dispensers. Have you wondered why some come in jars and others in spray bottles?

Having trouble producing stable foams?

Making foams, in other words introducing gas in a solid or liquid, is needed in industries like construction, composites, home care and personal care. Solid foam is a clever way to produce lightweight structures and insulation materials, whereas many personal care and detergent formulations are required to form a liquid foam. To produce solid foams, you need a blowing agent which introduces gas bubbles in the solid and a solid (often a polymer) that hardens around them. Liquid foams are mainly created by using surfactants and mixing air in. Earlier on this blog, we have explained how microfibrillated cellulose can be used for creating bubble-free gel coats. Could it also help forming intentional foam structures?

How to use MFC in cosmetic products? Interview with Cosmacon & Rainer Kröpke

Cosmetic products are one of the most exciting application areas for microfibrillated cellulose (MFC). The opportunities within this field are almost endless as Mr. Rainer Kröpke from Cosmacon GmbH has learned when working with MFC in cosmetic applications. Mr. Kröpke has a long experience in formulating cosmetic products first at Beiersdorf (Germany) and since 2012 as a consultant. Read below his interview where he shares his experiences with all our blog readers.
