Sources/Uses

Propylene series glycol ethers are used in surface coatings, leather, pesticides, electrical, industrial cleaners, resins, and printing inks; [ECETOC] Used as a coupling agent and solvent (degreasers, paint removers, metal cleaners, and hard surface cleaners), coalescent (latex coatings), coupling agent (water-based agricultural formulations), and chemical intermediate (epoxides, acid ester derivatives, solvents, and plasticizers); [OECD SIDS: Propylene Glycol Ethers - 2003]

Comments

Adverse effects in animal studies include adaptive liver changes and reversible CNS depression, but no hematological, genotoxic, or carcinogenic effects; [ToxPlanet: ECETOC] A skin and eye irritant; [ICSC] May cause moderate skin and eye irritation; May cause mild, reversible corneal injury; [Dow Chemical MSDS] See "Dipropylene glycol n-butyl ether."
