Endpoint summary
Administrative data
Description of key information
Ammonium zinc chloride dissioziates with humidity to ammonium chloride and zinc chloride,
Zinc chloride is corrosive based on animal skin irritation studies. Due the corrosive nature of zinc chloride to skin, eye irritation studies do not need to be conducted and hence no animal eye irritation data is available on zinc chloride.
Key value for chemical safety assessment
Skin irritation / corrosion

Justification for classification or non-classification
Based on the available data of the soluble zinc compounds, soluble zinc chloride is classified as corrosive (C;R34) according to EC criteria due to severe skin irritancy seen in animals at concentrations of 1% solution and irreversible damage to eyes caused by zinc chloride after accidental exposure in humans. Zinc chloride has also shown signs of respiratory tract irritation in single exposure studies (see acute inhalation toxicity).
