NEG and NIOSH Basis for an Occupational Health Standard: Propylene Glycol Ethers and Their Acetates
DHHS (NIOSH) Publication Number 91-103
This document deals with the propylene glycol ethers most commonly used in industry, namely methoxypropanol, methoxypropyl acetate and dipropylene glycol monomethyl ether. Both alpha and beta isomers are present in commercial methoxypropanol and methoxypropyl acetate. These isomers differ in toxicity and are therefore treated separately.
