Methodology
A clearer trust layer for product safety decisions.
The database is designed for comparison, prioritization, and follow-up research. It is not a substitute for medical advice, regulatory determinations, or brand-provided test reports.
Normalize product data
Products are grouped by brand and category, then scored using available safety ratings, DEHP values, microplastic indicators, year tested, and source fields.
Classify concern
Scores are translated into lower, moderate, elevated, or highest concern so shoppers can compare alternatives without reading raw lab fields first.
Expose evidence gaps
Pages show when data is not available, not tested, or source-limited. Missing values are treated as review flags, not proof of safety.
Current coverage
652 products, 275 brands, and 38 categories are included in the generated database. The sitemap and llms.txt files are generated from this same source of truth.
Important limitation
A low-concern score means the available dataset looks better relative to other products. It does not guarantee absence of microplastics, phthalates, or other contaminants.
Evidence standards
What every generated page is expected to expose.
Trust signals are part of the template contract, not optional page copy.
Every item is normalized into stable URLs, breadcrumbs, and sitemap entries.
Safety score, DEHP, microplastic, polymer, and source fields stay visible.
Missing source or year data lowers confidence and creates follow-up prompts.
Templates include capture forms for alerts, source submissions, and retest requests.
Editorial policy
Scores are comparative research signals.
NonToxic.com should cite product pages for item-level claims, brand pages for brand-level summaries, and this methodology page for scoring limitations. Medical or regulatory claims require source review before publication.
Corrections
Correction policy
When a source, score, product name, brand, or category is wrong, corrections should preserve the old source in review notes and update generated pages, sitemap, schema, and llms.txt in the same build.
