Amidst the growing concern about global warming caused by carbon dioxide emissions, biofuels have been regaining their popularity. Biofuels are similar to fossil fuels, except that they're made from present-day plants referred to as biomass. The two most common types of biofuels used today are ethanol and biodiesel.
Biodiesel is a renewable alternative fuel for diesel engines. It is made by combining alcohol (usually methanol) with vegetable oils or animal fat. However, it is highly perishable and starts to oxidise soon after it has been produced. It reacts with atmospheric oxygen to produce various acids or polymers, which if found in high enough concentration, can cause fuel system corrosion and deposits. Such effects in turn can lead to filter clogging and fuel system malfunctions. This is why antioxidants play a crucial role here.
Most raw vegetable oils used for manufacturing contain vitamin E (tocopherols), a naturally occurring antioxidant. However, they get destroyed during the oil refining process. Commercial antioxidants are added to avoid oxidation and to extend the shelf life of biodiesel.
Camlin Fine Sciences (CFS) offers the Xtendra range of traditional shelf life solutions which contains antioxidants such as Butylated Hydroxytoluene (BHT) or Tertiary-Butylhydroquinone (TBHQ) in specific carrier to improve the biodiesel stability.
The Vertically Integrated CFS manufacturing process ensures complete traceability and a reliable supply of products, giving our customers better control over their shelf life extension requirements.
