Sodium Benzoate (E211) is the sodium salt of benzoic acid, it is a white and odorless solid. It is naturally present in blueberries, apricots and cinnamon and is used as a preservative for its fungicidal antimicrobial activity. It is active only at acidic pH between 3 and 5 and to obtain optimal preservation of the product it must be combined with one or more preservatives, such as Potassium Sorbate.
Preservative permitted by the "Icea" Organic certification
The preservative solution is prepared with:
80 gr of distilled water
10 g of potassium sorbate
10 g of sodium benzoate
dissolve the potassium sorbate and the sodium benzoate, first in a little water (taken from 80 g) once dissolved well, the remaining water will be added.
This preservative mixture is used to the extent of 2.5 gr in a preparation of 100 grams total (ie 97.5 gr cosmetic preparation and 2.5 gr of preservative).
This is a basic preservative (pH 7.5) and therefore must be acidified to pH 5 to preserve, with lactic acid or citric acid.
