Cetylpyridinium chloride (CPC) is a cationic quaternary ammonium compound used in some types of mouthwashes, toothpastes, lozenges, throat sprays, breath sprays, and nasal sprays. It is an antiseptic that kills bacteria and other microorganisms. It has been shown to be effective in preventing dental plaque and reducing gingivitis. It has also been used as an ingredient in certain pesticides. Though one study seems to indicate cetylpyridinium chloride does not cause brown tooth stains, at least one mouthwash containing CPC as an active ingredient bears the warning label "In some cases, antimicrobial rinses may cause surface staining to teeth," following a failed class-action lawsuit brought by customers whose teeth were stained. The name breaks down as: 1. * cetyl- means cetyl group, which derives from cetyl alcohol that was first isolated from the whale oil (Latin: cetus); 2. * pyridinium refers to the cation [C5H5NH]+, the conjugate acid of pyridine; 3. * chloride refers to the anion Cl−.

Making cesium dichromate from chromium metal and cesium chloride
To explore an alternative route to make cesium metal, I made some cesium dichromate. Cesium dichromate can be reduced to cesium metal. Because I did not have any chromate compounds, I made the potassium dichromate myself by dissolving chromium metal and oxidizing it with hydrogen peroxid
