Alpha-Hydroxyisobutyric acid is a metabolite of methyl tert-butyl ether (MTBE). MTBE may be obtained through environmental exposure. MTBE is rapidly eliminated from the body mainly through expired air as the unchanged compound. MTBE is to some extent metabolised to t-butyl alcohol (TBA) and formaldehyde and oxidised to 2-methyl-12-propanediol and a-hydroxy isobuturic acid. Alpha-Hydroxyisobutyric acid has been used as an arial bactericide.

Cetyl glycol favors the decomposition of the metal-organic precursor, formation of an intermediate Co(2+)Fe(3+)-oleate complex, and the nucleation of nanoparticles at lower temperatures. Cetyl glycol is a reducing agent that can be used in cosmetics.
