TU Freiberg develops new process for natural-based microparticles in cosmetics

25.09.2019

Microplastics is spreading more and more, especially in the sea. The impact of microplastics on animals and humans has not been researched in the long term. In the next years, the Chair of Fluid Mechanics and Turbomachinery at the TU Bergakademie Freiberg wants to develop together with scientists of the Johannes-Gutenberg-University Mainz and the TU Munich as well as three industrial partners an innovative atomization process for the production of new bio-based and biodegradable microparticles.

These environmentally friendly microparticles shall replace environmentally harmful microplastics in shampoos and other cosmetics.

The Bioshampoo project examines the complete process chain from conception of the process, particle development, integration into a final product (shampoo), and final biodegradability testing after initiation into the water cycle.

"Microplastics" consists of plastic particles with a size of a few nanometers to a few millimeters. Petroleum-based microplastics is currently contained in many cosmetic products. In sewage treatment plants, these very small particles are difficult to break down or filter off.

In the new atomization process, the feed material obtained from natural substances is first melted and then the melt is forced through a nozzle via a high speed gas flow.

The melt decays into individual droplets, which form predominantly spherical particles after solidification. These are supposed to perform the same function as microplastics in cosmetics, but the participating scientists expect that the nature-based microparticles can be removed much easier and faster from the wastewater.

The project is funded under the Central Innovation Program for Small and Medium-sized Enterprises (ZIM) with a total of approxemately 1.1 million Euros. In the project application and implementation, the scientists were and are supported by the innoscripta GmbH Munich.

Im Focus: Solving the mystery of quantum light in thin layers

A very special kind of light is emitted by tungsten diselenide layers. The reason for this has been unclear. Now an explanation has been found at TU Wien (Vienna)

It is an exotic phenomenon that nobody was able to explain for years: when energy is supplied to a thin layer of the material tungsten diselenide, it begins to...

Im Focus: An ultrafast glimpse of the photochemistry of the atmosphere

Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have explored the initial consequences of the interaction of light with molecules on the surface of nanoscopic aerosols.

The nanocosmos is constantly in motion. All natural processes are ultimately determined by the interplay between radiation and matter. Light strikes particles...

Im Focus: Shaping nanoparticles for improved quantum information technology

Particles that are mere nanometers in size are at the forefront of scientific research today. They come in many different shapes: rods, spheres, cubes, vesicles, S-shaped worms and even donut-like rings. What makes them worthy of scientific study is that, being so tiny, they exhibit quantum mechanical properties not possible with larger objects.

Researchers at the Center for Nanoscale Materials (CNM), a U.S. Department of Energy (DOE) Office of Science User Facility located at DOE's Argonne National...

Im Focus: Novel Material for Shipbuilding

A new research project at the TH Mittelhessen focusses on the development of a novel light weight design concept for leisure boats and yachts. Professor Stephan Marzi from the THM Institute of Mechanics and Materials collaborates with Krake Catamarane, which is a shipyard located in Apolda, Thuringia.

The project is set up in an international cooperation with Professor Anders Biel from Karlstad University in Sweden and the Swedish company Lamera from...

Im Focus: Controlling superconducting regions within an exotic metal

Superconductivity has fascinated scientists for many years since it offers the potential to revolutionize current technologies. Materials only become superconductors - meaning that electrons can travel in them with no resistance - at very low temperatures. These days, this unique zero resistance superconductivity is commonly found in a number of technologies, such as magnetic resonance imaging (MRI).

Future technologies, however, will harness the total synchrony of electronic behavior in superconductors - a property called the phase. There is currently a...
