Raspberry ketone as a multifunctional preservative
Has anyone tried Ashland’s Phyteq (raspberry ketone) as a multifunctional preservative? It only came onto the market in March of this year, so I suspect that very few people have tried it let alone heard of it. Lotioncrafter is selling Phyteq N, but it’s a bit concerning that it’s already a closeout item. I may call them this week to ask what happened. 0.5% raspberry ketone with 1% 1,2-hexanediol passed a microbial challenge test and was great against fungi. You can see the results of the test below, and also a link to their product description.
