I am looking for a broad spectrum preservative that I can use for lotion and cream emulsions that have a pH range of 4-4.5. I tried using Optiphen plus (phenoxyethanol, caprylyl glycol, sorbic acid), but noticed that it severely irritated my skin. I made a small batch without the preservative, applied it and noticed that I did not get any burning sensations like I did when I added the preservative.I would really appreciate suggestions on preservatives that can be purchased by home crafters and can be used in emulsions within a 4-6 pH range. I would prefer to stay away from phenoxyethanol, dehydroacetic acid, and anything with parabens.I have been looking at phenylpropanol EHG (phenylpropanol and ethylhexylglycerin) on Making Cosmetics and Euxyl K900 (Benzyl alcohol and ethylhexylglycerin) on Lotion Crafters. Any thoughts on these?
Any suggestions will be very much appreciated!
