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.

An exact ATE value (LD50/LC50) takes priority; otherwise the category's GHS converted point estimate is used. Components with neither are treated as "unknown."

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.
