I posted a few weeks ago about having a problem with Microcare SB as people were reacting to it. I was advised to add it at the hot phase. I did this, however, this is the result (below). I made 12 batches, all the same.
Would really appreciate some advice. My heart is breaking. Thanks.

It would seem to me that the reason you are experiencing bacterial/fungal growth on your product is that your preservative is simply inadequate.
You have plenty of "natural" ingredients in your formula which are breeding grounds for bacteria and fungus. Preservatives like Microcare SB are often too weak to deal with these sorts of formulations (despite the fact that it is a preservative found in many "natural" high-risk formulas).
I would recommend using a more effective preservative such as parabens. If you don't like using parabens then you could try one of the many phenoxyethanol blends available or other preservatives such as Germall Plus which are generally more effective.
P.S. It should be noted that no preservative is better than another and the most effective preservative will always vary from formula to formula.
Hope this helps.
Has anybody used Microcare DB before? It's Dihydroacetic Acid & Benzyl Alcohol.
It did help. But now the preservative is not working.
Grateful for any insights - thank you.
Eliminate the Soy Lecithin from your formula ... that is probably what is causing the microbial contamination which is most certainly yeast/mold. That will help considerably. Adding the preservative hot or cold will not make any difference whatsoever.
If eliminating the Soy Lecithin alone is not sufficient, you will have to add a fungicide to bolster the preservation ... Phenethyl Alcohol or Naticide should work well in this formula. It would also help if you added a chelating agent ... Dissolvine GL47S would help boost your preservation.

So if I'm using 1% Microcare SB or DB, how much Naticide should I use please?
Thanks so much for your help!
No, you do not need Lecithin in your formula. You can use 0.6% Naticide to compliment you Microcare.

There are plenty of other options that are both palm oil-free and don't irritate your skin. And, are you certain that any of the ingredients in the Caprylhydroxamic GG mix are indeed derived from palm-oil? Perhaps that's not the case.

Yes, that is correct ... it is harder to preserve products when you use Siligel as opposed to straight Xanthan Gum ... I try to avoid using anything with Lecithin in it. And, if I do have a multicomponent ingredient with one being Lecithin, I know immediately that I'm going to have to use Phenethyl Alcohol in the preservation system.
