Potassium salt from Sorbic acid, a fatty acid naturally present in the bays of the Sorbier.

Inci: Sorbate potassium

Description : Potassium sorbate is a synthetic product that mimics the natural molecule. It is in every way identical. Its manufacture is ecological thus its safe use, provided that the concentration is respected. The use of synthetic potassium sorbate is more ecological than the manufacture of potassium sorbate stemming directly from nature (which would require large amounts of organic matter, which is not really viable or possible, given the quantities used). In any case, it is the same molecule. For all these reasons, some still consider it as a "natural" product. Potassium sorbate therefore ranks in natural conservatives, despite its synthetic nature. The choice to use it or not is personal :) The fact remains that it is a clean, safe, reliable, healthy curator for us and for the environment.

Properties : Antifungal, antibacterial.

Use :Conservative in the formulas containing an aqueous phase.

Applications:Any product containing an aqueous phase and whose pH is between 2.0 and 6.5.

Concentration: 0.15 to 0.3% if used alone or 0.1 to 0.2% if it is combined with another preservative. Often uses sodium benzoate, but can also be used alone with a stable aqueous phase.

Solubility : Potassium sorbate releases sorbic acid, its active ingredient, in water. Soluble in cold water.

Aspect : Underbidded white powder or granules.

pH : Effective at pH located between 2.0 and 6.5

* Face creams require a pH of 5. For eye contour creams, the pH of which must be ideally 7 Dermasoft Pentiol Eco.


Note that water -free formulas do not require a preservative, on the other hand, it will be advantageous to use an antioxidant (like vitamin E, antioxidant oil which slows down fat, but which is not a preservative).

We recommend avoiding infusions and favoring aloe gel (already contains a preservative), distilled water and hydrosols. According to chemists, the latter are not stable, but we are herbalists :) And we love hydrosols, which can keep a good year or more (rather stable for water). With hydrosols in the aqueous phase, an emulsion h/e keeps, thanks to the potassium sorbate, about a year, which is very acceptable to us. We prefer to make living products that keep for a few months rather than dead products that remain stable for years!

Recipe : Neutral cream / around 500 ml

g aloe gel
75 g hydrosol of your choice
50 g olivem 1000
50 g Macerated oil a choice
1.4 g potassium sorbate
50 Benzoin dye drops
5 g Vitamin E

Heat the first two ingredients over low heat. In a 2e Papon, heat all the rest over low heat. Add the potassium sorbate to the aqueous phase. Bring the aqueous phase to around 50 degrees C and the oily phase at around 70 degrees C (the olivem 1000 must be melted) then add the water to the fats, stirring with an electric mixer on foot for 2- 3 minutes. Add the Benzoin dye and vitamin E. Built in a jar Masson (jar In glass for canned) 500 ml, label and keep cool. Serve if necessary and add essential oils to choose from.
