Potassium Sorbate is a food-grade preservative ingredient used in cosmetic formulation to help control yeast and mould in water-containing products. It is the inactive salt of sorbic acid and becomes active in the presence of water, which is why it is added to the water phase of a formula. This is a raw preservative ingredient rather than a finished product, and it is commonly paired with sodium benzoate for broader coverage. It is most effective in more acidic formulas.

♡ Why we love it: We choose to stock Potassium Sorbate because it is a useful preservation tool for formulators who understand how to build an appropriate water-based system. It is especially practical in lower-pH products where a simple preservative pairing is needed.
