Guest guest Posted April 29, 2004 Report Share Posted April 29, 2004 Hello I just wanted to know if vodka can be used with essential oils & spring water without the addition of a preservative? If so, what does the percentage does the vodka have to be? Thanks in advance for your assistance. Cheers Anita Grant Quote Link to comment Share on other sites More sharing options...

Yes. >If so, what does the percentage does the vodka have to be? From what I've been told, " Cosmetic Microbiology: A Practical Handbook " ,by K. Brannan (Editor) says that 20% ethyl alcohol is self preserving and " Preservatives for Cosmetics, " by D.C. Steinberg, 1996, p.11 says more than 15% ethyl alcohol is self preserving. If you're using 100 proof Vodka, you will probably need at least 30% to 40% 100 proof Vodka to make your product self-preserving.

Guest guest Posted April 29, 2004 Report Share Posted April 29, 2004 What else besides alcohol (as to avoid a permit) could be used as a preservative for an EO/Hydrosol/Water mix? Cyndi If you're using 100 proof Vodka, you will probably need at least 30% to 40% 100 proof Vodka to make your product self-preserving.

You COULD use many different preservative systems but Germall Plus and Disodium EDTA come to mind. Good processing will help a lot.

Guest guest Posted May 10, 2004 Report Share Posted May 10, 2004 Hi Maurice, Thanks for your help! I just wanted to know what the % would be for 90 proof vodka, this is the highest I could get my hands on. BTW ~ I have ordered the books that you mentioned below from Amazon.
