pH Adjustment for Salicylic Acid and Papaya Enzyme Toner

Based on the staff's response regarding your toner formulation for acne and dark spots using Salicylic Acid EZ (Water Soluble), Papaya Enzyme (Papain), and distilled water:

• The staff cannot confirm the exact pH level of your final mixture.
• They recommend measuring the pH after mixing the ingredients.
• If the pH is found to be below 5, they suggest using Triethanolamine to adjust it upwards.
• They anticipate that if the pH is below 5, it might only be slightly lower.

Therefore, the key step is to measure the pH of your finished toner and adjust with Triethanolamine if necessary to bring it above 5.
