Short term exposure worker (systemic effects)
It is not possible to derive a DNEL for acute effects based on the available data. The acute toxicity of Triethylenglycoldivinylether is low with respect to the oral and dermal routes of exposure. The inhalative route is not a relevant route of exposure due to the low vapour pressure (0.0042 hPa) and use (no formation of an inhalable aerosol).
Long term exposure worker (systemic effects)
Inhalatory and dermal
The DNELs for inhalatory and dermal long term exposure are derived from the NOAEL obtained in an oral repeated dose study (BASF 73R0162/03041). In this 2-generation reproduction toxicity study (comparable to the current OECD guideline 416) rats were exposed to 0, 100, 300, 1000 mg/kg bw/day for up to 20 weeks. Effects on liver and kidney weight (with corroborative histopathological findings) were observed in males and females at 1000 mg/kg bw/day. A dose level of 300 mg/kg bw/day is considered as NOAEL.

Oral, inhalatory and dermal
The DNELs for oral, inhalatory and dermal long term exposure are derived from the NOAEL obtained in an oral repeated dose study (BASF 73R0162/03041). In this 2-generation reproduction toxicity study (comparable to the current OECD guideline 416) rats were exposed to 0, 100, 300, 1000 mg/kg bw/day for up to 20 weeks. Effects on liver and kidney weight (with corroborative histopathological findings) were observed in males and females at 1000 mg/kg bw/day. A dose level of 300 mg/kg bw/day is considered as NOAEL.
