People started adding natural substances (salt, sugar, vinegar, etc.) to food hundreds and even thousands of years ago to better preserve it and to lengthen shelf life. Today, food additives aren't just used to preserve foodstuffs, but also to maintain appearance, flavour, texture, freshness, constitution, and even nutritional value. Industry demand is constantly growing as there are increasingly more processed foods in supermarkets and convenience shops.

The story goes that, back in 1618, a farmer from Epsom in England wanted to give his cows water from a nearby well, but they refused to drink it due to its bitter flavour. Nevertheless, the water seemed to heal the scrapes and rashes on the animals' skin. The farmer from Epsom had just discovered magnesium sulfate. It wasn't until 1775 that magnesium (MG) was recognised as a chemical element, and 1808 that it was converted into metal for the first time.

Chemical brightening of Aluminum with BD Brial HD

Aluminium is one of the most efficient and sustainable metals. It can be used in practically any weather conditions, it has all the required characteristics for a good thermal insulator, it saves energy, and is completely recyclable. Thanks to the innovation of production processes, at the start of the 20s, the price of aluminium dropped by 80%, leading to its popularisation in all types of structural, mechanical, and decorative applications: doors, windows, sliders, roofs, latticework, balustrades, and so much more.

Due to its greater thermal stability, better fire behavior and greater mechanical resistance, PIR sandwich panels (polyisocianurate) have become the preferred option for designers, engineers and architects to the detriment of PUR panels (polyurethane), predominant until now. The main difference between both types is that PIR panels have more isocyanate content and this gives better properties to the final material. Such properties are increasingly necessary due to a more strict regulation in terms of fire safety and the focus on energy efficiency.

In industry, it's common to apply pigments to resin for reasons that are often merely aesthetic. Nevertheless, pigments so much more than just a dash of colour. Handling, compatibility, sun resistance, toxicity and, why not, price, are some of the main concerns companies have when using pigments in their resins. Making the right or wrong purchase can make a big difference.

It can be found in the skeletons of animals, in teeth, eggshells, coral reefs, mollusk shells, and in many types of soil and in water. Calcium is essential to the lives of plants and animals, and to the industry as well. For that reason, our third article in celebration of the International Year of the Periodic Table features this element with the symbol 'Ca'.

Cosmetics made with synthetic substances have gotten a bad name recently, coinciding with the rise in natural cosmetics which are increasingly present in women's vanity cabinets. That bad name is undeserved, according to Juan Carlos Montoro, Director of Grupo Barcelonesa's cosmetics business sector. He explains that "both natural and synthetic products are completely safe considering the fact that both must comply with the same safety conditions". Below we will dismantle, or should we say cleanse away, some of the false myths about chemical products in cosmetics:
