Check Ingredients

Use this skill to turn an ingredient list into a source-backed safety review.

The goal is not to produce a generic "clean/dirty" score. The goal is to verify the ingredient list, scrutinize claims, separate real hazards from weak signals, and explain the practical risk in plain language.

Workflow

1. Capture the product facts.

   • Product name, brand, size, country/retailer, link, date checked, and how the ingredient list was obtained.
   • Preserve the raw ingredient text verbatim when available.
   • Create a normalized ingredient list without changing uncertain names. Note typos or likely synonyms separately.

2. Verify the ingredient source.

   • Prefer back-label photos, brand pages, regulatory labels, SDS sheets, official product pages, or retailer pages with complete ingredients.
   • Do not treat marketplace copy as verified if it lacks the full ingredient list.
   • If sources disagree, show the conflict and keep the version provenance clear.

3. Check each ingredient.

   • Role in formula: active, preservative, solvent, emulsifier, fragrance, colorant, pH adjuster, botanical, filler, etc.
   • Human-health flags: endocrine, reproductive/developmental, carcinogenicity, genotoxicity, systemic toxicity, sensitization, irritation, phototoxicity, inhalation, ingestion, and absorption.
   • Pregnancy/child flags when relevant.
   • Environmental flags separately from human-health risk.
   • Whether the flag applies to the raw ingredient, the finished product, or only a specific exposure route.
