Freshness is key
Is it Safe to Keep Oil in PET Bottles?
BioNatal’s Black Seed Oil is always fresh and there is no difference in the 16oz Glass or PET bottle. PET bottling containers do not contain BPA or Phthalates. It is safe to keep Black Seed Oil in PET bottles if the bottle is not exposed to the sun or will be sitting in the shelf for quite some time.
BioNatal LLC is bottling every week for one week of sales. If you buy BioNatal Black Seed Oil in PET container, be sure the oil was transferred from glass jar to a PET container within the last 7 days only.
PET is the same material which is used by grocery stores for sunflower and olive oils.
