Available tools
check_chemical
Check chemical hazard and regulatory records by substance name or CAS number. Use when the user asks if a chemical is SVHC-listed, NIOSH-listed, GHS-classified, ICSC-covered, occupationally hazardous, or relevant to cosmetic/food safety cross-references. Do not use for batch SVHC screening, broad hazard discovery without a substance name, cosmetic formula checks, food additive safety, or drug interaction questions. The response includes identifiers, ECHA SVHC status, NIOSH REL/PEL/IDLH data, GHS classifications, ICSC safety-card fields, and cosmetic/food cross-reference matches.
check_svhc_list
Screen a list of substances against the EU ECHA SVHC Candidate List. Use when the user provides multiple chemical names or CAS numbers and asks which are SVHCs, REACH candidates, restricted substances, or substances of very high concern. Do not use for one-off full hazard profiles, NIOSH/GHS/ICSC exploration, or non-EU regulatory questions that are not SVHC checks. The response includes per-substance match status, resolved identifiers, SVHC inclusion details, reason fields, dates, and source links where available.
search_chemicals
Search chemical safety datasets by hazard keyword, exposure route, organ effect, or regulatory concept. Use when the user asks for chemicals related to carcinogenicity, respiratory effects, liver toxicity, skin sensitization, endocrine activity, GHS phrases, NIOSH topics, or SVHC categories. Do not use when the user has a single exact substance to profile or a list to screen only for SVHC status. The response includes ranked matches from SVHC, NIOSH, GHS, and ICSC sources with dataset labels, identifiers, hazard snippets, and source-specific fields.
