potassium sorbate at a slightly higher pH (~5.2)
I’m eager to hear your thoughts and get any advice on using potassium sorbate as the only anti-mold/fungi/yeast preservative in water type formula at pH ~5.2, or, at the lowest, pH 5.
I have anti-bacterial preservatives in the formula but they are not known to be much anti-MFY; for ex, 1,2 hexandiol.
I read things that say that at pH 5, potassium sorbate is only effective to ~37% (https://lotioncrafter.com/products/potassium-sorbate).
My starting concentration to test is 0.2% of potassium sorbate.
Would love to hear your thoughts on whether this sounds likely to succeed or problematic.
