Information on toxicological effects
Symptoms: No information available
Delayed and immediate effects as well as chronic effects from short and long-term exposure
Acute effects: Gastro-intestinal distress
Chronic toxicity
Prolonged and excessive inhalation exposures to antimony trioxide may result in respiratory effects, antimony pneumoconiosis, pulmonary fibrosis, inflammation of the lungs, airway obstruction, broncospasms, reproductive effects, gastrointestinal upset, liver effects, and neurological effects (muscle weakness, subnormal gait).
Prolonged and excessive oral exposure may result in gastrointestinal discomfort and ulcers, blood effects, liver effects, neurological effects inflammation of the mucous membranes and stomatitis.
In a recent 90 day oral study in male and female rats, no adverse effects were observed at doses of 1000, 5000, and 20000 ppm. The No Adverse Effect Level for antimony trioxide was 20000 ppm for both sexes.
In a developmental study in Sprague-Dewley rats consisting of three treatment groups and a control group, each containing 26 females at doses of 2.6, 4.4, and 6.3 mg/m3, no developmental effects were observed. The LOAEL for material toxicity was established at 2.6 mg/m3. The NOEL for developmental toxicity was 6.3 mg/m3, the highest exposure level evaluated.
Mutagenicity: no data available
Carcinogenicity
Carcinogenicity – rat – Inhalation
Tumorigenic: Carcinogenic by RTECS criteria. Respiration: Lungs, Thorax, Tumors Liver: Tumors
Limited evidence of carcinogenicity in animal studies.
IARC
- Class 2B: Possibly carcinogenic to humans (antimony)
- Class2A: Probably carcinogenetic to humans (lead)
- Class 1: Carcinogenetic to humans (arsenic)
NTP: No component of this product present at levels greater than or equal to 0.1% is identified as a known or anticipated carcinogen by NTP.
OSHA: No component of this product present at levels greater than or equal to 0.1% is identified as a known or anticipated carcinogen by OSHA.
Antimony trioxide has been classified by IRAC as a Class 2B. An IARC 2B material exhibits sufficient evidence in animal tests to be a possible human carcinogen. Antimony oxide production has been determined by ACGIH to be a carcinogenic risk. Antimony trioxide has been identified by the EPA as a suspected lung carcinogen. Historical studies have concluded that exposure to elevated levels of antimony oxide may cause lung carcinoma. However, the most recent study conducted under the EPA’s Voluntary Test Program by the Antimony Oxide Industry Association (AOIA), has concluded that antimony oxide does not cause lung cancer in rats at occupational exposure levels. The levels tested ranged from 0.005 mg/m3 to 6 mg/m3 (from one tenth to ten times the OSHA TWA Threshold Limit Value.
Reproductive toxicity
Reproductive toxicity – rat – inhalation
- Effects on Fertility: Post-implant mortality (e.g., dead and/or resorbed implants per total number of implants).

Repeated dose toxicity
Prolonged and excessive inhalation exposures to antimony trioxide may result in respiratory effects, antimony pneumoconiosis, pulmonary fibrosis, inflammation of the lungs, airway obstruction, broncospasms, reproductive effects, gastrointestinal upset, liver effects, and neurological effects (muscle weakness, subnormal gait).
Prolonged and excessive oral exposure may result in gastrointestinal discomfort and ulcers, blood effects, liver effects, neurological effects inflammation of the mucous membranes and stomatitis.
