Animal studies show that 1,1,1,2,3,3,3-heptafluoropropane (HFC 227ea) has low acute inhalational toxicity.
In accordance with
section 2 of REACH Annex XI, an acute oral and dermal toxicity study do
not need to be conducted as the substance is a gas.
inhalation toxicity studies with 1,1,1,2,3,3,3 -heptafluoropropane
indicate that the acute inhalation toxicity study is low.
In the key study (WIL
Research Laboratories, 1992) no mortality was observed and a 4 h-LC50 >
788696 ppm (5483776 mg/m3) was
established. At this concentration, only transient signs of anaesthesia
during the exposure period and a decreased body weight and body weight
gain at the end of the 14 -day observation period were
Based on 4 h LC50 of > 788696
ppm (5,483,776 mg/m3) in
rats in a reliable OECD guideline study, 1,1,1,2,3,3,3
-heptafluoropropane does not have to be classified for acute toxicity in
accordance with EU
Directive 67/548/EEC and EU Classification, Labeling and Packaging of
Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
