Q: Can I use potassium sorbate alone as my preservative?
A: It is mainly effective against mould and yeast, many formulas use it together with another preservative to broaden protection.

Q: Why does pH matter so much?
A: Potassium sorbate is most effective in acidic formulas and becomes much less effective at higher pH.

Q: Can I use it in soap?
A: It is generally not suitable for high pH products like true soap.
