Sources
Sources are selected for the claim being made. A chemical database, product label, regulation, and medical authority answer different questions.
Primary authorities we commonly consult
- U.S. Centers for Disease Control and Prevention (CDC) and NIOSH — public-health, exposure, and occupational-safety guidance.
- U.S. Occupational Safety and Health Administration (OSHA) — workplace hazard communication, labels, and Safety Data Sheet requirements.
- U.S. Environmental Protection Agency (EPA) — chemicals, pesticides, disinfectants, environmental safety, and disposal guidance.
- NIH PubChem — chemical identifiers, structures, properties, safety information, and linked data sources.
- European Chemicals Agency (ECHA) — European chemical classification, labeling, and regulatory information.
- NIST Chemistry WebBook — evaluated chemical and thermochemical data.
- International Chemical Safety Cards (ILO/WHO) — concise international safety information for chemical substances.
- Poison Control — U.S. poison-exposure triage and emergency guidance.
Product-specific sources
The product label and the manufacturer’s current SDS are usually the most relevant sources for a commercial product’s ingredients, concentration, intended use, first-aid statements, storage, incompatibilities, and disposal. Because formulations change, readers should verify that the document matches the exact product and revision date.
Research literature
Peer-reviewed research may be used to explain mechanisms or fill gaps in official guidance. We consider study design, conditions, sample size, relevance to the actual product or exposure, and whether the finding is consistent with stronger evidence. A laboratory result at a high concentration is not automatically generalized to routine household use.
How citations appear
Article-specific sources should be listed or linked on the page where the claim appears. A link to this general directory does not replace claim-level sourcing. If a cited page moves or becomes unavailable, we may replace it with the current official location or an archived equivalent.
Source limitations
Links do not imply endorsement, and inclusion does not make ChemicaLife an affiliate of the source. Databases may aggregate third-party submissions and can contain conflicting classifications; when evidence conflicts, we explain the uncertainty or choose the more conservative safety conclusion.
