Method and limits

  • Prevalence counts published products whose decoded ingredient list matches this substance or one of its label synonyms, using the same matching the score itself uses. It describes our catalogue of 893 products, not the Indian market as a whole.
  • Presence is not dose. An ingredient list gives order, not quantity, unless the pack declares a percentage. Nothing here estimates how much of this substance any product contains.
  • A classification is not a verdict on a product. An agency classifies a substance under defined conditions of exposure; whether that matters in a given food or cosmetic depends on route, concentration and use.
  • No regulatory rows. This substance is not matched in our regulatory warehouse, so the concern above rests on the cited authority alone.
  • Last updated. This register entry was last changed on 28 September 2026.
  • Corrections. Every figure here is reproducible from the sources named. If something is wrong, tell us and we will correct it and say what changed.
