Sources/Uses

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

Comments

Possibly forms explosive peroxides; No listed effects of short-term or long-term exposure; [ICSC] No evidence of skin sensitization in study of 82 human volunteers; Signs of CNS and respiratory depression observed in oral lethal-dose study of mice; Increased relative liver weight (without corresponding histopathology) observed in 13-week dermal study of rats; No evidence of embryotoxicity or teratogenicity; [IUCLID] May cause mild eye irritation; Prolonged skin contact may cause mild irritation; [Dow Chemical MSDS] See "GLYCOL ETHERS."
