Probable Routes of Human Exposure:

NIOSH (NOES Survey 1981-1983) has statistically estimated that 25,310 workers (50 of these are female) are potentially exposed totriethylene glycol monobutyl ether
or(2-(2-(2-butoxyethoxy)ethoxy)ethanol)in the US. Occupational exposure totriethylene glycol monobutyl ethermay occur through inhalation and dermal contact with this compound at workplaces wheretriethylene glycol monobutyl etheris produced or used(SRC). Monitoring and use data indicate that the general population may be exposed totriethylene glycol monobutyl ethervia ingestion of contaminated drinking water, and dermal contact with products containingtriethylene glycol monobutyl ether.

Artificial Pollution Sources:

Triethylene glycol monobutyl ether's or(2-(2-(2-butoxyethoxy)ethoxy)ethanol) production and use as a plasticizer intermediate(1), a solvent for cellulose nitrate, cellulose ethers, chlorinated rubber, poly(vinyl acetate), colophony, many other natural and synthetic resins, stoving chemicals, wood paints, pharmaceutical and cosmetic preparations, as well as drying greases and oils(3), as a solubilizer for mutually incompatible liquids(3), in the production of household and metal cleansing agents as well as for wood preservation(3), in cutting and hydraulic oils, production of inks(3), as a leveling agent(3), in the leather auxiliaries industry(3), and in the chemical, textile, and transportation industries(2) may result in its release to the environment through various waste streams(SRC).
