GHS health hazard (sum-of-parts) calculator
Classify a mixture for the additivity-based health endpoints — skin/eye, STOT, sensitisation, carcinogenicity, mutagenicity, reproductive toxicity, aspiration. Pick an endpoint, enter each component's category and concentration, and the engine sums against the GHS cut-offs.
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.
