Is the preservative-free hydrosol safe from microbial contamination?
Yes — every batch is microbiologically tested and released within strict limits, thanks to hygienic production, aseptic filling and sealed containers.
| Test | Typical Limit (cosmetic standard) |
|---|---|
| Total plate count | ≤ 100 CFU/mL |
| Yeast & mold | ≤ 100 CFU/mL |
| Pathogens (E. coli, S. aureus, P. aeruginosa, C. albicans) | Absent / per 1 mL |
For retail products with a long shelf life, we recommend formulating with a compliant preservative system at the finished-product stage — our OEM team can help. Request the latest microbiological COA for your batch.
