คำถาม
What is the effective pH range for Encapsulated Salicylic Acid (BHA, Timed-Release) in a formulation, and does the manufacturer specify a single optimal pH point within this range?
คำตอบ
For Encapsulated Salicylic Acid (BHA, Timed-Release), the optimal pH range for it to work effectively in a formulation is approximately 3.5 to 5. The manufacturer indicates that performance is highest within this range, without specifying a single best point. This type of encapsulated salicylic acid, such as the Encapsulated Salicylic Acid (Liquid, Timed-Release, Wash-Off), is designed to be gentler on the skin due to its timed-release mechanism, and it functions well within this slightly acidic to near-neutral pH range.
