Hi Bettijo,

There are differences in all the preservatives that you mentioned. The

LiquaPar and the Germaben/Germall products are from ISP Sutton Labs.

You can find alot of information on these preservatives on their site. There

are several 'LiquaPar' preservatives:

LiquaPar Oil - Isopropylparaben (and) Isobutylparaben (and) Butylparaben

LiquaPar Oil PE - Phenoxyethanol (and) Isopropylparaben (and) Isobutylparaben

(and) Butylparaben

LiquaPar Optima - Phenoxyethanol (and) Methylparaben (and) Isopropylparaben

(and) Isobutylparaben (and) Butylparaben

The LiquaPar Optima is the one that is most like Phenonip. It is a fairly

new product from ISP. These can both be used to preserve

emulsions---formulations that contain water.

LiquaPar Oil is best for anhydrous formulations--no water. It is not a good

choice for most emulsions or formulations with water. But this would be fine

for a salve or ointment.

The standard rule in choosing the most effective preservative---and

percentage of that preservative--goes back to the 'challenge test' providing

the very best answer. We don't know for sure unless the testing is done.

But aside from that, I think we can rely to some extent on the research that

these companies have already conducted, use GMP, and plain common sense. For

example, ISP had done a lot of work to determine which preservatives are best

for different types of formulations and they also have the recommended range

of percentages to use. I suggest reading up on them to see what the company

has to say. According to Steve at ISP, the best preservative they have for

high water content emulsions is Liquid Germall Plus...so that's the one I

use. He says the LiquaPar Optima is a good choice for products that need a

wide global market---like in Japan--and that it is a good preservative, but

that it is not as effective as Liquid Germall Plus.

It may be that you will need to use a couple of different preservatives to

suit your different formulations. There are other preservatives from other

companies but these are the ones that I am most familiar with...hope this

helps
