In the preparation of water-containing petroleum jelly with sorbitansesquioleate from the TMF, I make precipitation in the waterphase. Can these be avoided?

The concentration of sorbinzeic acid in the water phase of the CR è me is +/-0375%. At 20 ° C, the solubility of sorbic acid in water is 0.16% and at 50 ° C = 0.55%. Thus, the modus operandi of the TMF must be followed and the solution with sorbic acid should not be allowed to cool too strongly. A precipitate may be expected at room temperature.
