1-Butoxypropan-2-ol - 5131-66-8

Key Functions: Industrial / Manufacturing, Solvents & Cleaning

1-Butoxypropan-2-ol is, also commonly referred to as propylene glycol n-butyl ether (or PnB), is a propylene glycol ether used primarily as a solvent in chemical manufacturing (UNEP 2003). Glycol ethers are clear liquids with high boiling points, low to moderate volatility, and high water solubility (HERA 2005). In 1999, about 285 million pounds of propylene glycol ethers were produced in the United States. Propylene glycol ethers are manufactured by reacting propylene oxide with methyl alcohol or n-butyl alcohol. They are often used as solvents, chemical intermediates and coupling agents in cleaners, coatings, paints, lubricants, and cosmetic products (UNEP 2003). In household cleaners, 1- butoxypropan-2-ol typically varies in concentration from 0 – 6.5% of the total product formulation (HERA 2005).
