Interpretation of results:
GHS criteria not met
Conclusions:
SMCA is not a skin irritant
Executive summary:

The sodium salt of monochloroacetiac acid (SMCA) was tested for skin irriation / corrosion in acordance with EU protocol B.4 under GLP. The substance was found not to be irritating to the skin.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not irritating)

Additional information

key study (EU protocol B.4, GLP) indicates that SMCA is not a skin irritant

key study (EU protocol B.5, GLP) indicates that SMCA is a moderate eye irritant

no data on respiratory irritation


Justification for classification or non-classification

Based on the available animal data and experience in humans SMCA need to be classified for irritation to eyes (GHS/CLP cat. 2).

Although SMCA did not show skin irritation, CLP ANNEX VI classification indicates classification as a skin irritant cat. 2 (H315).
