CFI Potassium Sorbate is a food-grade preservative used primarily to help control spoilage caused by yeasts and moulds in suitable foods and beverages. It is the potassium salt of sorbic acid and performs most effectively in acidic, water-containing products. The powder dissolves into the water phase and is particularly useful in products such as sauces, syrups, fruit preparations, fillings and beverages where its use is permitted. It can also be used as part of a suitably designed cosmetic preservation system.
♡ Why we love it: We choose to offer Potassium Sorbate because it is a practical preservation ingredient for makers who understand the importance of pH, accurate weighing and finished-product testing. It is especially useful when a food or cosmetic formula needs targeted yeast and mould control without introducing a strongly flavoured preservative.

Who it's for
- Food makers producing acidic, water-containing products
- Small-batch producers who can measure ingredients and pH accurately
- Formulators building a complete preservation system
- Cosmetic makers working with lower-pH water-based products
- Product developers able to validate microbiological shelf life
- Direct consumption as an undiluted powder
- Oil-only or fully anhydrous products

How to use
- As a Food Preservative: Dissolve into the water phase and use at the level permitted for the specific food or beverage category.
- In Acidic Foods: Confirm the final pH, as preservative performance reduces as the pH rises.
- In Combined Systems: Use with other permitted preservation methods or ingredients where broader protection is required.
- As a Cosmetic Preservative: Add at 0.1-0.3% to the water phase of a suitable lower-pH formulation.
- Processing Tip: Weigh accurately rather than measuring by volume.
- Testing Tip: Validate the finished product through appropriate microbiological and shelf-life testing.
Safety instructions
- Use only within the permitted limit for the intended application
- Do not consume the concentrated powder directly
- Avoid inhaling airborne powder
- Avoid contact with eyes
- Use clean, dry equipment when handling
- Keep tightly sealed and protected from moisture
- Keep out of reach of children and pets
- Commercial food products should be made under an appropriate food-safety and quality system
Faqs
Q: Is Potassium Sorbate a complete broad-spectrum preservative?
A: No. It is used mainly for yeast and mould control and may need to be combined with other preservation measures.
Q: Why is pH important?
A: Potassium Sorbate becomes less effective as the product becomes less acidic, so the final pH must be measured and
controlled.
Q: Can it be added to oil-based products?
A: No. It requires a water phase in which it can dissolve and become active.
Q: Can the cosmetic usage rate be used for food?
A: No. Food usage limits depend on the product category and applicable regulations.

I combined this with sodium benzoate (food-grade) to preserve my African herbal mixture that I sell. As a test, I filled one 1-liter bottle with the unpreserved herbal concoction and another with the preserved herbal mixture. By the second day, I spotted fungi growing in the unpreserved herbal mixture, while only none appeared in the preserved one. It's the second week and haven't observed any growth of fungi. Additionally, these additives didn’t alter the aroma of the herbal blend, and it maintained its effectiveness.
The service is excellent and will definitely order from you again.
I ordered my Potassium Sorbate at 07h30 and it was delivered to my door by 3pm the same day. Potassium Sorbate is perfect for sugar based goods, to stop fermentation or mould from growing.
