Cosmetics1 use researched1 sourced claims
Where it turns up: clay filler, oil absorption, mattifying. Detox My Life researched kaolin under one use, because the same substance means something different in each use. Every claim below carries its evidence tier, how sure the research is that it applies here, and the sources it cites. The level is computed by the app's own deterministic engine, so the page says exactly what the app would.

While naturally occurring kaolin can contain heavy metal impurities like lead and arsenic, cosmetic-grade kaolin is purified and strictly tested to ensure these contaminants are below regulatory limits for dermal leave-on products. Studies indicate that heavy metals from clay pastes do not penetrate human skin.
- Why here
- Kaolin is a mineral-derived ingredient used in dermal leave-on products, and minerals can naturally contain heavy metals.
- What would have to be true
- Dermal application of cosmetic-grade kaolin in leave-on formulations.

Not researched here
The engine has no dossier for kaolin when cooked with heat, in cold food, as a finishing ingredient, in heated food packaging or other uses. The app researches an ingredient for the use it infers from your product, so a scan fills these in; this page only shows what has already been researched and source-verified.
This is research, not medical advice. Detox My Life shows sourced claims sorted by evidence tier. It does not diagnose, treat, or tell you to start or stop anything. Talk to a qualified professional about your health.
Scan your own. The app reads any product label with your camera, works out how you are about to use it, and researches every ingredient for that use with live sources. Every scan adds to a Detox Score for your home, where 50 is a typical home in your region, and a plan of next swaps.
