Toxicity class & GHS lookup
Not a static standards table — this shows the toxicity classes, GHS pictograms and signal words **actually approved** for an ingredient on real registration certificates worldwide.
Common ingredients
Method: taken from the actual field values on certificates held for that ingredient in official national registers — not laboratory recommended values. The same ingredient may be approved at different classes depending on formulation, content and use.
About this tool
Are these standard recommended values?
No. These are the toxicity classes and GHS markings **actually approved** on real registration certificates for that ingredient. The same ingredient can be approved at different levels depending on formulation, content and use.
Why does one ingredient show several toxicity classes?
Because classification follows the product, not the molecule: content, formulation and national assessment outcomes are all recorded on the certificate, so the distribution reflects real-world approvals rather than one standard answer.
Why is the pictogram breakdown marked as sample-based?
GHS pictograms are stored as arrays; when many certificates match we aggregate a sample. It shows the main hazard categories, not an exact full-population share.
