The leading blog on nanocellulose
Having demonstrated the viscosity stabilizing effect of Exilva in starch adhesives, for this third blog post in the corrugated boards application series, I will focus on the effect on glue ability and production speed.Read more
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.
There is a strong need to disinfect and sanitize frequently touched surfaces. Exilva Microfibrillated cellulose (MFC) is a biobased structuring agent that can thicken household disinfectant and cleaning products at low to high pH, as well as with oxidizing compounds.
Hydroalcoholic hand sanitizers are the best option to keep up your hand hygiene when soap and water are not accessible. They are one of the most used and needed products these days. If you are considering formulating a hand sanitizer, read about how you can use Exilva Microfibrillated Cellulose, a biobased material, to structure and thicken your formulations as well as provide a non-tacky feel.
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.
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.
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.
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?
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?
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?
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.
