Cfi Potassium Sorbate - Food Grade 1KG

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.

As a Lower-pH Preservative: Adjust the final product to about pH 4.4 for maximum efficacy. Processing Tip: Potassium Sorbate is not effective at all in products with a pH over 6. Processing Tip: It is commonly paired with sodium benzoate for broader preservation support. Safety Instructions Keep well sealed between uses Store away from children, animals, moisture, sunlight, and heat Patch test finished products before wider use Discontinue use if irritation occurs If pregnant or breastfeeding, seek professional guidance before use FAQs Q: Does Potassium Sorbate preserve against bacteria on its own?

A: No. It is effective against mould and yeast, but is commonly used with sodium benzoate for broader protection. Q: Where is Potassium Sorbate added in a formula? A: It is dissolved in the water phase. Q: Why does final pH matter so much? A: It is most effective in more acidic formulas and is not effective in products above pH 6.
