Hard soap
Dear all
A Hard soap with a high pH of around 11 can be contaminated? -

Hi,
no, it shouldn’t. pH higher than 10 and lower than 3 is self-preserving. -
With pH and Aw, you’re priob ok if no compromising additions (e.g,. milk). pH 10 should not be seen as prohibitive. lou’ll need to be > 11 for that.

I know it’s going to be an extremely rare event - but you asked
Bhathena, Z., Barchha, N. and Sivaram, T.K., Prevalence of Moderately Halophytic Aerobic Gram Positive Cocci in Bath Soap Bars with Special Reference to Nesterenkonia Species.

Interesting. @PhilGeis what would you use to prevent this?. I’d go for something like imdz urea.

I’d be reactive in this. If it did come up - I’d 1st try to find and eliminate the bug from raws/the system. Your idea is prob a good one.
