Materials & ingredients
| Material or ingredient | What it is | Concern level | Why it's flagged here |
|---|---|---|---|
| Zinc oxide | Zinc oxide is a mineral compound and the FDA-recognized active ingredient in most diaper-rash ointments and mineral sunscreens — it forms a physical barrier on skin and has a long safety record at the concentrations those products use. | Use with caution | The concern here is the reported metal finding in the finished product. This test does not identify zinc oxide as the source. |
