Paint manufacturers have been formulating paints containing microspheres in many years. Formulators can use microspheres to increase the solid content of a coating while maintaining the proper application and flow characteristics. Higher solids can reduce volatile organic compounds (VOCs), shrinkage and drying time. But there can be problems with settling and sedimentation, as well as floating of the microspheres. In addition, cost of certain types of microspheres can be high. In this article I will show you how the microfibrillated cellulose technology can give anti-settling and anti-sedimentation of microspheres, as well as enabling you to choose less expensive microspheres and obtain the same performance, which typically has been associated with more expensive types.Read more
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.
Microfibrillated cellulose (MFC) has many properties wanted in cosmetic products: good skin feel, desired rheological properties and improved stability of formulations. Moreover, it is a natural raw material, an increasing trend in cosmetics. MFC is made of natural cellulose sources and can be prepared by different processes. Both the source and the process determine the composition of the MFC and possible impurities that the MFC could have. It is, therefore, essential to have good control of both the composition of the material (see also our blog post about the raw materials of MFC) and of the process to prepare it. This is especially true when it is to be used in certain applications. Cosmetic products are an example of applications where the purity of MFC is essential since it affects us, our society and our environment all at once.
Over the last several years consumers have become more and more aware of the environmental impact of cosmetic products. Indeed cosmetic products end up down the drain and in the water system after a shower. The trend today is, therefore, to use natural raw materials to replace synthetic ingredients and reduce the environmental impact.
The challenge for formulators is to find a natural material that performs very well in the different types of cosmetic products. Microfibrillar Cellulose, MFC, an environmentally friendly, sustainable and effective additive, represents a good opportunity to fulfil this requirement. But why is MFC relevant for cosmetics, and where can MFC improve the natural profile of cosmetics and personal care products?
