GHS acute toxicity (ATE) calculator
Compute a mixture's acute toxicity estimate by the GHS additivity formula — 100 / ATEmix = Σ (Ci / ATEi) — for any route. Enter each component's ATE (LD50/LC50) or its acute-tox category and concentration.
Deterministic calculation from the data you enter. A draft result for review by a qualified professional — not a compliance determination. Nothing is stored.
Tired of transcribing hazard data off your supplier SDSs? Sign up and extract it automatically from the actual SDS — which also captures supplier-specific impurities a manual entry can't.
Classify the whole mixture, not one endpoint
GHSLogic runs every GHS endpoint from your real supplier SDSs, then drafts a review-ready SDS and labels — with the rule path behind every result.
