About This Product

Potassium Sorbate

A preservative primarily used in the food industry but is also used in winemaking and skincare products to inhibit micro-organisms and increase shelf life. E Number 202.

Potassium Sorbate, which is the potassium salt of Sorbic Acid, is a synthetic preservative that inhibits the growth of yeast, moulds and bacteria in cosmetics and other topical applications. Optimum antimicrobial activity is attained at pH values of up to 5.

Potassium Sorbate is very good at tackling mould and as such is a useful addition to products such as clay masks, pigmented make-up, exfoliating creams and moisturisers containing fresh herbal extractions.

Acidification is recommended for products that are too basic, for example with citric or lactic acid. The successful use of potassium sorbate depends very much on the skill of the user and careful experiments are advisable. Please check the pH value and carry out a series of tests with different concentrations of potassium sorbate.

It is best to work in potassium sorbate with hand-warm water, then the pH value can be corrected with lactic or citric acid if necessary. 

Potassium Sorbate Solution: mixing ratio 1:5 (20% solution means: 1 part potassium sorbate granules and 4 parts water)

If you want to use the granules directly, the use concentration is 0.1 – 0.26%.

The preservative effect of potassium sorbate is optimal at a pH value of 4 – 5.5. From a pH value of 7, the effect is cancelled!
