    hello everyone. I’m deciding on a preservative for both a face cream and face essence with a pH range of 5-6. The essence is rich in extracts. Should I combine euxyl PE 9010 with pentylene glycol or caprylyl glycol and ethylhexylglycerin?. Additionally, I need to choose a supplier between Kopcerin PE 1090, euxyl PE 9010, and ParbFree PE91. While I’m aware of Ashland’s reputation, euxyl PE 9010 is notably more expensive than the others. Is the higher cost justified, or are the alternatives equally effective?

    Choice of supplier is sometimes forced by volume you want as some will not sell small volumes. Suggest you also consider Arxada. These guys have consolidate some of the older supplier houses - Dow MC, Lonza etc. and rather than just repackaging combinations are developing preservatives - real stuff, not natural eye of newt toe of frog BS.. Their phenoxy may not be special but their profits are investments.
