Glycerol

Glycerol /ˈɡlɪsərɒl/ (also called glycerine or glycerin; see spelling differences) is a simple polyol (sugar alcohol) compound. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature. The glycerol backbone is central to all lipids known as triglycerides. Glycerol is sweet-tasting and is non-toxic.

Production

Glycerol can be either synthetic, or derived from plants (usually soybeans or palm) or animals (usually tallow). It can also be a blend of both animal and vegetable oils. Approximately 950,000 tons per year are produced in the United States and Europe; 350,000 tons of glycerol were produced per year in the United States alone from 2000 to 2004. Production will increase as the EU directive 2003/30/EC is implemented, which requires the replacement of 5.75% of petroleum fuels with biofuel across all Member States by 2010, as glycerol is a byproduct in the production of biodiesel. It is projected that by the year 2020, production will be six times more than demand.

Music video

The music video for "Glycerine" was notable for being shot in a very short time period when the band was on tour in the United States. The video was shot so quickly because the band's visas had expired. Though simple and unadorned, the video was highly acclaimed and won several awards, including the MTV Video Music Award - Viewer's Choice as well nominated for Best Alternative Video at the 1996 MTV Video Music Awards. The music video was directed by Kevin Kerslake and shot in Atlanta, Georgia on 2 October 1995.
