Answer

Using BHT with Oil Soap and Oil

Yes, it is generally recommended to use an antioxidant like Butylated Hydroxytoluene (BHT) when mixing Oil Soap with oil to create an oil-based cleanser.

Here's why:

  • Oil Oxidation: The oils used in your formulation are susceptible to oxidation over time, which leads to rancidity, an unpleasant odor, and degradation of the product quality.
  • BHT as Antioxidant: BHT is a common antioxidant used in cosmetic and food formulations specifically to prevent the oxidation of oils and fats, thereby extending the shelf life of the product.
  • Oil Soap Function: While Oil Soap helps create the cleansing oil, it does not provide antioxidant protection for the oil itself.

Adding a small percentage of BHT (typically 0.01-0.1%) to your oil phase before mixing with the Oil Soap will help protect the oils from going rancid.
