C&EN Senior Correspondent Marc S. Reisch points out that manufacturers have used silicones for decades in an array of personal care products.
Antiperspirants and underarm deodorants account for about half the entire U.S. personal care market for silicones. Manufacturers voluntarily stopped using one type of silicone ingredient in personal care products over the last decade.
Now government regulators in Canada are proposing regulations limiting use of another widely used type of silicone ingredient. They cite concerns that the ingredients might built up in the environment and harm wildlife.
The article notes that some manufacturers, despite the concerns, are sticking with the traditional ingredients, termed cyclic methylsiloxanes.
Others are using the concerns as a basis for jumping on the natural ingredient bandwagon and reformulating their products with other silicones or as "silicone-free."

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
