  • Water, do I need a preservative?

    Posted by Oladoo on July 27, 2020 at 9:58 am

    Hello,

    I’m using a small amount of water to dissolve some solids and incoperate into a balm. The water makes 3.95% of the entire formula. The rest of the ingredients are oils and wax. 
    1. Do I need a preservative?
    2. Will the water turn the product rancid fast? Do I need  to add something to stall that? if yes, what?
    Thanks

    1. Yes, use a preservative.
    2. Without seeing the whole formula, I can’t answer.
