When using dropper pipettes, NBR or TPE?
1 year ago
Currently bumping into a question that is surprisingly hard to answer:
For perfume and eu de parfum with an oil base, for storage but also mixing for use, is it better to go with the TPE bulbs(thermoplastic elastomer) or NBR (Nitrile rubber)?
It seems everywhere I look people use TPE but as far as the materials go, NBR seems better to essential oils, extracts, etc. based on material. Am I missing something?
Thank you for your insight,
