“It’s not so much that we’re interested in processing the eggs; that’s just demonstrating how powerful this process is,” says Gregory Weiss, UC-Irvine professor of chemistry and molecular biology & biochemistry. In conjunction with Australian chemists, UCI chemists have developed a method to unfold proteins which have been “misfolded” while being processed. The methods in... Read more »
Having both hydrophilic and hydrophobic character, C8-C10 fatty alcohols find use as a nonionic solvent in the production of surfactants and detergents. In the food and cosmetics industries they find use as emulsifiers, emollients and thickeners. In cosmetic emulsions fatty alcohols are used to provide consistency. In technical emulsions they are used as co-surfactants and... Read more »

Two 600-foot ships collided on Monday due to fog causing a leak of Methyl tertiary-butyl ether (MTBE). This also caused a shut down of a portion of the Houston Ship Channel. MTBE is a gasoline additive that is not easy to clean up, according to the commander of the Houston-Galveston Coast Guard District. For more... Read more »
The chemical industry lobby is pushing congress to pass new legislation on the regulation of chemicals. The lobby feels the Toxic Substances Control Act of 1976 (TSCA) is outdated and leaves too much authority to the states when determining regulation. A new federal bill would help to create a more standard set of rules throughout... Read more »
“It’s arguably one of the most important interactions between molecules, because it occurs in water where biology and so much technology happens,” says UW-Madison chemical and biological engineering professor Nicholas Abbott. A group of UW-Madison researchers, including Abbott and UW-Madison chemistry professor Sam Gellman have provided new insights on hydrophobic interactions within complex systems. The... Read more »
Mainly used as a nontoxic plasticizer in PVC, cellulose resin and synthetic rubber, Acetyl Tributyl Citrate (ATBC) is also valued for its biodegradability in nail polishes and other cosmetics. ATBC provides many improvements over di-butyl phthalate in cellulose nitrate films due to its lower volatility, better resistance to yellowing and better adhesion to metals. It... Read more »
