Answer
Using Encapsulated Salicylic Acid in Bar Soap
Yes, Encapsulated Salicylic Acid (Liquid, Timed-Release, Wash-Off) can be used in bar soap formulations.
This product type is specifically designed for wash-off products, such as facial cleansers and shower products, which includes bar soap.
Key points for using this ingredient in bar soap:
- Usage Rate: The recommended usage rate is 1.6-6.6%. A concentration of 3.3% is equivalent to 1% Active Salicylic Acid (suitable for light acne), and 6.6% is equivalent to 2% Active Salicylic Acid (for heavy acne).
- Mixing: It can be mixed directly into the desired product and is water-soluble. However, avoid mixing at speeds higher than 1000 rpm to prevent damaging the encapsulation.
- FDA Limit: For over-the-counter products, the FDA limits Salicylic Acid concentration to no more than 2% (which corresponds to 6.6% of this Encapsulated Salicylic Acid product). Higher concentrations require medical supervision.
Ensure the bar soap formulation process is compatible with adding a liquid, water-soluble ingredient and that the mixing speed is controlled.
