Hydrogenated terphenyl

Hydrogenated terphenyl is used as a heat transfer fluid, as textile dye carriers, and as plasticizers. People who are occupationally exposed to hydrogenated terphenyl may experience skin irritation, headaches and sore throat. In laboratory animals, repeated exposure revealed increases in organ weights and decreases in body weights. The Dutch Expert Committee on Occupational Safety (DECOS) has evaluated whether there could be derived a threshold level of exposure below which no adverse health effects are expected, also not after repeated exposure. The DECOS advises a health-based occupational exposure limit for hydrogenated terphenyl of 7.4 mg/m3 (8-hour time weighted average concentration).
