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.
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.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.

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.
I live in India and the only preservative I'm able to get hold of here is phenoxyethonol . I did a little research online about it and learnt that it is a broad spectrum preservative and is very stable .But, I again read here on the forum that it is not a good choice and should not use... I AM CONFUSED .. request some help please in the matter ...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.
00 91 98990 32261 is the no I whatsapp them. They also send me their latest catalogue.You can try Pioneer Chemicals. They have a choice in preservatives and other soap stuff. They ship wherever required. I have had ppl shipping stuff to me in Dubai
For what it's worth, I do not use preservatives in soap -- hard bars or liquid. I do, however, add antioxidants ROE and vitamin C to either the oils as soon as they are opened (to prolong shelf-life) or to the oils/fats/butters as I'm making the soap. Nevah evah had a problem. It should be noted, I do not add "bug food" or mess with lowering the LS just to be safe.One situation where adding preservative to soap is a good idea is when you dilute liquid soap with a lot with water. A good example is the thin soap used in foamer dispensers. When the concentration of soap in the diluted product is low enough, the soap cannot provide the stable alkaline pH which is critical for soap to be self preserving.
