Chemical uses, chemistry information and industry news
Although the terms safety data sheet (SDS) and material safety data sheet (MSDS) are often used interchangeably, there’s one crucial difference between them. All SDSs follow the GHS’s standard sixteen-section format, whereas MSDS formats can vary between organisations.Despite the differences in presentation, SDSs and MSDSs both provide important information about the hazards posed by a particular chemical. This includes details...
Formaldehyde is a toxic organic compound that exists in many types of food. Fruit and vegetables such as apples, bananas, carrots and spinach all contain formaldehyde. It’s also found in beef, poultry, fish, and coffee beans.Although it’s illegal for manufacturers to use formaldehyde as a food additive, the substance is produced naturally in some foods as a byproduct of metabolic...
Although they may look complicated, safety data sheets (SDS) are actually quite straightforward to read because they're divided into different sections. However, you may need some basic chemistry knowledge to understand some of the more technical information they contain.Safety data sheets - also known as material safety data sheets (MSDS) or product safety data sheets - are included in the...
Citric acid is a naturally-occurring substance found in citrus fruits like lemons and limes, although it can also be manufactured on an industrial scale. When manufactured, it’s commonly used in food processing as a flavouring, preservative, or colourant. Citric acid is also an ingredient in some cosmetic and personal care products, as well as non-toxic cleaning agents.In fact, this weak...
The purpose of a safety data sheet (SDS) is to provide vital information on how to store, handle, use, and dispose of chemicals correctly. It can help anyone working with hazardous substances to understand the specific risks posed by certain chemicals.Many chemicals are hazardous in some way, for example, they might be corrosive, toxic, explosive, or carcinogenic. It’s therefore essential...
If you’re a film fan, you might be wondering how realistic the scientific concepts explored in space operas like Star Wars really are. Is Star Wars based on science? Could it really exist? Is the Death Star scientifically possible? While the Star Wars movie franchise has some plausible science elements, it’s highly fictionalised. In fact, many aspects depicted in the films...
From relatively harmless compounds such as sodium bicarbonate to toxic reagents like sulphuric acid, our homes contain a variety of common chemicals. These chemicals are often found in the kitchen, bathroom, garage, or shed.When people think about common chemicals at home, most only consider those that are classified as compounds (mostly inorganic) and/or have some commercial value. However, if you...
Brick acid is simply a solution of hydrogen chloride, otherwise known as hydrochloric acid. As the name suggests, it’s commonly used for removing dirt, limescale, cement, grease, and surface debris from bricks.A highly corrosive and powerful cleaner, brick acid removes the sodium carbonate from walls through a neutralisation reaction between an acid and a base. Read on to learn more...
Chromatography is an analytical technique in chemistry that’s used to separate the constituent components of a mixture, either for analytical or industrial purposes. The method was originally developed in 1903 by the botanist Mikhail Tswett, who used the technique to separate plant pigments. Although there are now several different types of chromatography, the basic principles remain the same. The process of chromatography...
