Potassium Sorbate Granules
INCI: Potassium Sorbate
Mixing ratio 1: 5 (1 part Potassium Sorbate to 5 parts in total, that means it is a 20% solution in water)
If you want to use the granulate directly, the application concentration is 0.1-0.26%.
The preservative effect of potassium sorbate is optimal at a pH-value of 4 - 5.5, and the effect is cancelled from a pH-value of 7! Acidification is recommended for products that are too basic, for example with citric or lactic acid. The successful application of potassium sorbate is fundamentally dependent on the skill of the user and careful tests are therefore advantageous. Please check the pH-value and make a test series with different concentrations of potassium sorbate.
The best way to incorporate potassium sorbate is to use it in hand heat, after which the pH value is corrected with lactic or citric acid if necessary.
