  Hello, in a formula with the following inci: Alcohol, Aloe barbadensis leaf juice, glycerin, lavandula angustifolia oil, potassium sorbate, sodium benzoate, citric acid.After a few days a white precipitate appears at the bottom, what could it be due to? What do you think might be interacting? Thanks for your answers, greetings.

  @Econatural Both Potassium sorbate and especially Sodium benzoate are not quite soluble in Ethanol, so you can make one sample without these materials to see if the problem is fixed…also, if you’re using more than 20% of Ethanol (which I believe is your case), chances are that you don’t need preservatives.
