ITDF is a supplier of ingredients for cosmetics and household chemicals. Their website has interesting documents regarding regulations for manufacturing cosmetics.
There is also a section with formulations, or recipes to make a large number of ingredients.

Cost of chemicals
Market prices of chemicals are useful for economic studies and chemical engineering design projects. This information can be hard to find for students.
To help with these task we found a website from ICIS with prices of a large number of chemicals. Although they might be a bit dated, thay can be useful for student papers or projects.
Another source of estimated prices of chemicals can be found here (prices in UK pounds)

Laboratory glassware
Chemical labs use a great variety of glass equipment, including, flasks, burettes, etc. We found a couple links thay may amuse those who spend many hours a day using glassware.
1)The original design of the Erlenmeyer flask.
2) A hybrid between a flask and an erlenmeyer, called fleaker. It combines the conical and cylindrical shapes providing the advantages of both. It might be so, but it also seems that it might be hard to clean if anything happens to stick to the interior walls.

Cellulosic ethanol process
One of the multiple process for cellulosic ethanol is the one of bluefire (Arkenol). In their website they show flowsheets and pilot plant schematics.
One of the reasons in producing cellulosic ethanol as a renewable fuel is to use agricultural residues that would otherwise be burned or disposed of as waste.

Vapor Liquid Equilibrium
One of the most common separation operations is distillation. Design of distillation columns requires thermodynamic data on vapor liquid equilibrium of the mixture of interest.
Many thermodynamic database exist, some of which are accesible to subscribers only. Some are, however, open to the general public. The best ones are those who provide citations to the original sources, which facilitates evaluating the reliablity of the data.
Today we'd like to point out CHERIC(Chemical Engineering Research Information Center) from Korea. It has vast amounts of data on VLE of binary systems and a database that includes thermophysic properties and equilibrium data for:
2000 hydrocarbons and light gases.
200 polymers and solvents.
2000 electrolyte solutions
Some other sources of thermodynamic data include:
Shuzo One's website.
The COCO package includes thermodynamic data on 150 substances.

Chemical Engineering design projects
For those looking for chemical engineering design projects, West Virgina University has many interesting ones in DOC and PDF format.
They can be immediately useful as an example of a design project or for future reference. Topics range form optimizations of existing projects to mnore comprehensive large projects.

Chemical plant in Star Trek 2009
Good news for chemical engineering and science fiction fans. The new Star Trek movie (2009), has a very industrial look, and many scenes were filmed in actual plants. More specifically, the engine room of the Enterprise is actually a Budweiser Brewery in which one can clearly see the fermentors and piping.
As an interesting side note, the same plant was previously used as in the 80's Sci-Fi tv show "V".
According to its official site, a power plant was also used as a filming location.
For more on this, please check out the production notes from the official website.
