EmergingIrritant · allergenconfidence 50%
Carnauba wax is linked in studies to rare cases of allergic contact dermatitis and cheilitis when used in dermal leave-on products like lip balms and mascaras.
- Why here
- Carnauba wax forms a film on the skin and lips in leave-on products, allowing for prolonged contact that can trigger sensitization in susceptible individuals.
- What would have to be true
- Direct skin contact with products containing carnauba wax, such as lip balms, lipsticks, and mascaras. Symptoms are rare and typically involve redness, itching, swelling, or rashes.

Not researched here
The engine has no dossier for carnauba wax (copernicia cerifera cera) 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.
