Potassium Sorbate (preservative) - OGR20
Description: Potassium Sorbate is a preservative that is generally perceived as “safe” due to the inactive salt of the Sorbic acid. Sorbic acid is naturally present in some fruits. However, almost all Sorbic acid is synthetically produced worldwide in a chemical nature-identical connection equal to the natural molecule.
Potassium Sorbate can be solved in water easily (to a maximum of 58%), where it is converted into Sorbic acid. It is not a widely applicable preservative and is therefore best combined with other preservatives. It is most effective at a low pH (see table). In order to have an effect the pH of the formula must be as low as possible. An optimal pH is 4,4 (70%). Sorbic acid is very effective against fungi, less with yeast and not effective against bacteria.
It is an unsaturated fatty acid and therefore subject to oxidation. The use of an oxidant like Tocopherol is therefore recommended. Be aware for UV-light sensitivity, which causes some yellowing in a solution.
