Using Encapsulated Salicylic Acid (Timed-Release) in Soap
Question
Is Encapsulated Salicylic Acid (Powder, Timed-Release) suitable for use in a facial soap formulation? If not, what is the recommended alternative and why?
Answer
Regarding the use of Encapsulated Salicylic Acid powder in facial soap, it is not recommended. The powder form is designed for timed-release, gradually releasing the active ingredient over several hours. However, in a soap formula, it would be washed off the skin too quickly, preventing it from effectively releasing the salicylic acid over time.
For soap formulations, the liquid form of Encapsulated Salicylic Acid (Timed-Release) is recommended instead. This is because the liquid form has a positive charge, which allows it to adhere to the negatively charged skin. This adherence helps it remain on the skin even after washing, allowing the timed-release mechanism to work effectively.
