Mixture acute toxicity calculator.
Enter each ingredient's concentration and acute toxicity estimate (ATE). The calculator applies the GHS additivity formula and gives the category for oral or dermal exposure.
Enter at least one ingredient with a concentration and an acute toxicity estimate (ATE).
This covers acute oral and dermal toxicity only, using category limits of 5, 50, 300 and 2000 mg/kg (oral) and 50, 200, 1000 and 2000 mg/kg (dermal). Skin, eye and aquatic hazards use different rules; see GHS mixture classification, explained. Use ATE values from a reliable source and have a competent person confirm the result before it goes on a document.
