GHS mixture calculators
The same deterministic engine behind GHSLogic, free and no-signup — each calculator shows the math behind the category. No AI, nothing stored.
Acute toxicity (ATE)
The ATEmix additivity formula per route (oral / dermal / inhalation) from component ATEs or categories.
Open calculator →Aquatic toxicity
The Chapter 4.1 summation method — acute and chronic, with M-factors for very toxic components.
Open calculator →Flammable liquid
GHS category from the mixture's own flash point and initial boiling point (mixture-level, not sum-of-parts).
Open calculator →Health hazards (sum-of-parts)
Skin/eye, STOT, sensitisation, CMR and aspiration — concentrations summed against the GHS cut-offs.
Open calculator →Need the whole mixture classified?
These cover one endpoint at a time. GHSLogic runs every endpoint from your real supplier SDSs, drafts a review-ready SDS, and generates labels — with the rule path behind each result.
