Clay Masks
Hi! So I made a batch of cream using the Phytocide preservative. I have never tried it before so I had no idea how bad it stunk! Anyway it passed all our micro biology testing but I can’t sell it because it’s impossible to scent. My question is, if as long as I stick to the 20% max guideline, do you think I could add clay and turn it into a mask? In other words, will Phytocide be a strong enough preservative? Could I also add Optiphen Plus? If needed?

You mean aspen bark extract? Sorry but it’s not a proper preservative in my opinion. Kind of thing you find on Etsy. Optiphen Plus is fine.

Yes as Belassi said, the consensus amongst most chemists seems to be that phytocide doesn’t provide sufficient protection and clay is one of the hardest ingredients to preserve.
Effective preservation can’t be summed up into a couple of sentences. Have you seen the preservation strategy and reviews here: http://www.makingskincare.com/preservatives/ There are a huge number of factors to take into consideration (eg cfu/ml of each ingredient, pH, GMP, polyol/alcohol etc content, Aw, chelators, container’s ease of contamination, whether ingredient is a nutrient for microbes eg milk, clay, protein, aloe, hydrosols etc).
