11. Toxicological information
Acute toxicity
LD50 (oral, rat): > 20 g/kg
The literature data available to us do not conform with the labelling prescribed by the EC. The EC has dossiers of the manufacturers which have not been published.

Subacute to chronic toxicity
Animal experiments performed under conditions comparable with the workplace situation have shown the substance to be carcinogenic. The carcinogenic potential requires further clarification.

Further toxicological information
After inhalation: Irritations of the mucous membranes, coughing, and dyspnoea.
After skin contact: Irritations.
After eye contact: Irritations.
After swallowing: irritations of mucous membranes in the mouth, pharynx, oesophagus and gastrointestinal tract. Swallowing causes nausea and vomiting.
Damage of: kidneys

The following applies to trivalent antimony compounds in general: after uptake and absorption as a result of misuse or improper handling, drop in blood pressure, hepatotoxic effect, in some circumstances myalgia, dyspnoea, dermatitis. drop in blood pressure , cardiac dysrhythmia

Further ecologic data:
Do not allow to enter waters, waste water, or soil!

====================
13. Disposal considerations
Product:
There are no uniform EC Regulations for the disposal of chemicals or residues. Chemical residues generally count as special waste. The disposal of the latter is regulated in the EC member countries through corresponding laws and regulations. We recommend that you contact either the authorities in charge or approved waste disposal companies which will advise you on how to dispose of special waste.

Packaging:
Disposal in compliance with official regulations. Handle contaminated packaging in the same way as the substance itself. If not officially specified differently, non-contaminated packaging may be treated like household waste or recycled.

====================
