Cassella
Cassella AG, formerly Leopold Cassella & Co. and Cassella Farbwerke Mainkur AG, commonly known as Cassella, was a German chemical and pharmaceutical company with headquarters in Frankfurt am Main. Founded in 1798, in the Frankfurt Jewish Alley by Leopold Cassella, Cassella operated as an independent company until 1995, and was one of many predecessor companies of today's Sanofi. Its main products were dyes, drugs, cosmetics and various other chemical products. From 1949, Cassella focused increasingly on pharmaceuticals and cosmetics rather than its former primary focus, dyes. Much of its history is closely associated with the Gans family, a prominent family of industrialists and philanthropists and former owners of Cassella. History The company was founded as a spice store inside the Frankfurt Jewish Alley in 1798 by the Jewish businessman Leopold Cassella and his brother-in-law Isaac Elias Reiss, and was originally named ''Cassel & Reiss''.

Polyol
In organic chemistry, a polyol is an organic compound containing multiple hydroxyl groups (). The term "polyol" can have slightly different meanings depending on whether it is used in food science or polymer chemistry. Polyols containing two, three and four hydroxyl groups are diols, triols, and tetrols, respectively. Classification Polyols may be classified according to their chemistry. Some of these chemistries are polyether, polyester, polycarbonate and also acrylic polyols. Polyether polyols may be further subdivided and classified as polyethylene oxide or polyethylene glycol (PEG), polypropylene glycol (PPG) and Polytetrahydrofuran or PTMEG. These have 2, 3 and 4 carbons respectively per oxygen atom in the repeat unit. Polycaprolactone polyols are also commercially available. There is also an increasing trend to use biobased (and hence renewable) polyols. Uses Polyether polyols have numerous uses. As an example, polyurethane foam is a big user of polyether polyols. ...
