Additional information

Acute oral toxicity:

Oral toxicity (LD50) Rat for 2-(2-ethoxyethoxy) ethyl acetate was examined at dose concentration of 11000 mg/kg of body weight. This value suggests that the chemical does not exhibit acute toxicity through the oral route.

Acute inhalation toxicity:

A reliable handbook source Patty's Toxicology indicated that Rats and guinea pigs exposed to essentially saturated atmospheres of test substance at room temperature for 8 h all survived, although injury to the lungs and kidneys was observed at necropsy.

Acute dermal toxicity:

The LD50 for chemical 3-(methoxycarbonyl)-5-nitrobenzoic acid was determined to be >16 gm/kg when exposed to male/female rats orally.

Justification for classification or non-classification

The LD 50 values for 2-(2-ethoxyethoxy) ethyl acetate suggest that the substance will not be classified in any of the acute toxicity categories as per the C & L criteria set by EU.
