Administrative data

Description of key information

Data available indicate, that the substance is corrosive to rabbit skin as well as to the eyes. Corrosive properties are consistent with release of hydrochloric acid upon contact with water. Therefore, the hazard class of HCl regarding corrosivity is applied.

Key value for chemical safety assessment

Skin irritation / corrosion

Endpoint conclusion
Endpoint conclusion:
adverse effect observed (corrosive)

Eye irritation

Endpoint conclusion
Endpoint conclusion:
adverse effect observed (irritating)

Respiratory irritation

Endpoint conclusion
Endpoint conclusion:
no study available

Additional information

The substance reacts with water to release hydrochloric acid. Therefore, corrosive properties are expected.

A study on acute dermal irritation performed in 1973 under the US TSCA8e law, and some information on this study is publicly available. All six rabbits showed corrosion of the skin (Draize score 4 on a scale of 0-4) at the 4h, 24h and 48h reading. Shorter exposures or observation points are not available. Additionally, after application of the test substance in the eye lid of rabbits, a destruction of the entire eye structure in all test animals was observed (six out of six). [Stauffer Chemical Company,1973]

Since the substance releases hydrochloric acid upon contact with water, the legal classification of hydrochloric acid is applied (C; R34 or GHS Category 1B).


Effects on skin irritation/corrosion: corrosive

Effects on eye irritation: corrosive

Justification for classification or non-classification

Dangerous Substance Directive (67/548/EEC)

As a result of the available studies, the substance is considered to be classified as corrosive to skin and eyes (R34) under Directive 67/548/EEC, as amended for the 28th time in Directive 2001/59/EC.

Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008

The available information is considered reliable and suitable for classification purposes under 67/548/EEC. As a result of the available studies, the substance is considered to be classified as corrosive with Class 1B under Regulation (EC) No. 1272/2008, as amended for the second time in Directive (EC 286/2011).
