        Antimony Free / Reduced Antimony FR Solutions

        Reduced Antimony Trioxide (ATO) Flame Retardant Solutions – for healthier and more environment friendly products

        Antimony Trioxide Regulatory Status:

        • A carcinogen is a substance that may cause cancer or increase its incidence by inhalation, ingestion, or skin absorption.
        • Antimony Trioxide (ATO) is classified as Carcinogenic Cat 2 via inhalation route according to GHS and CLP rules.
        • NTP interpretation of the results of animal toxicity studies could impose additional hazard classifications: lung toxicity and reproductive toxicity.
        • Antimony trioxide is currently evaluated by ECHA due to its potential genotoxicity.
        • Additional tox studies are requested by ECHA.
        • Result: more stringent classification would be applicable.

        Future Regulation:

        Future regulation may change ATO classification and will follow by restrictions and bans:


        • Carc. category 2, inhalation route only (Sb 3+ powders only)
        • STOT RE category 2 (lung toxicity)
        • NO reproductive toxicity classification


        • Carc. category 1B, all exposure routes (all physical forms)
        • STOT RE category 1
        • Repr. category 2

        Occupational exposure limits might get more restricted:

        Current: 0.5 mg inhalable Sb/m3
        Possible: 0.1 mg respirable Sb/m3 ,0.006 mg respirable Sb/m
