Is the hydrosol tested for heavy metals and pesticide residues?
Yes — heavy metals and pesticide residues are tested on a regular basis and reported, supporting compliance with cosmetic and food-grade reference limits.
| Test Group | Typical Reference Limits |
|---|---|
| Lead (Pb) | ≤ 10 mg/kg (cosmetic reference) |
| Arsenic (As) | ≤ 2 mg/kg |
| Mercury (Hg) | ≤ 1 mg/kg |
| Cadmium (Cd) | ≤ 5 mg/kg |
| Pesticide residues | Per applicable standard (e.g., GB 2763 / EU MRLs where required) |
Send the limit values of your target market and we will run the corresponding test method and include it in the COA.
