Are you using it by itself? I think a more experienced soaper would be better with advice that since I've seen that in Optophen, you might need more than just that to effectively preserve anything.

Kcryss what is wrong with Optiphen or Germall Plus? Those two preservatives actually work well, especially when used in a dual preservative system. Optiphen is considered natural.

Phenoxyethanol does not preserve against mold and as a single ingredient only somewhat preserves against gram positive bacteria. So as a single preservative it is not a good preservative.

To answer your question you would be better off with a preservative that covers a higher ph range, and one that protects better against mold such as Suttocide A. Germall Plus is rated up to PH 10 so you may get away with it. My choice is Suttocide A and it works well in cream soap. If you are just whipping cp soap you do not need a preservative.

Hmm ... guess I should do more research before answering some questions. I actually use germall plus. I know it is not natural and is a formaldehyde releaser, but I prefer that to bacteria. I didn't realize Optiphen contains Phenoxyethanol, although I haven't used Optiphen as I've read that it isn't always as effective as a broad spectrum preservative.

Either way, I do still have a lot to learn about preservatives, even though I do insist on using them.

Thank you for recommendation. Actually I couldn't find any other preservatives around where I live. I should try to find suttocide A. Thank you.

I researched this to death and there's a difference of opinion among the experts. Some of them claim that no preservative is needed at all in liquid soap (due to the high PH). The other camp claims that since LS is a high percentage of water, you absolutely need preservative.

For liquid soap, I use the Liquid Germall Plus. It's the only one that works in the PH range of the LS. And this creates another topic of debate because LGP is not labeled for use in your LS. The reason why some people use it is only because they've personally tested it.

So if LGP is not labeled for LS, then there really does not exist a preservative that is labeled for LS. The "No Preservative" crowd will use this to boost their argument.

For lower PH products such as lotions and sprays, I use the Optiphen Plus.

On a side note, I've also learned that there is no such thing as a natural preservative.

Thanks Carl! I totally agree, there is no such thing as a "natural" preservative ... at least not one that actually works. Even lucidal has been shown to contain more then just fermented radish.

In your research, did you come across any documentation on lab tests for LS? That would certainly prove the case one way or the other on whether or not a preservative it needed.

No I didn't. My sources of information are conversing with highly qualified people on this forum and multiple articles on soaping sites throughout the internet world.

Another interesting source of information would be to google for some of the following things:
How mold grows
Ideal conditions for mold growth, etc.

You're going to get a lot of information that is not related to soaping, but you might get a general idea of how mold lives and forms.

It's very confusing, because many of the experts do disagree on this. And they both make some very valid arguments and both have very valid points!

Thanks @Carl

@cmzaha Interesting. I hadn't come across that one yet, but based on what I'm finding it seems to be a slightly better option then GP. Thanks for posting.
