Question
Regarding a formula containing Water, Witch Hazel (Extract 99% Tannins), and Encapsulated Salicylic Acid (BHA), I have two questions:
1. What is the acceptable pH range for this formula, especially if producing for commercial sale?
2. Is there a comparison of effectiveness between Capryloyl Salicylic Acid (LHA) Liquid and Encapsulated Salicylic Acid (BHA) for treating clogged pores? Which one is generally more effective and less irritating?
Answer
Based on the conversation, here is a summary of the answers to your last questions:
Regarding the formula with Water, Witch Hazel (Extract 99% Tannins), and Encapsulated Salicylic Acid (BHA):
- pH: A pH range of 3-5 is acceptable for this formula. However, if you plan to sell the product, the pH should not be lower than 3.5. It was also noted that Witch Hazel extract (99% Tannins) can have a strong odor.
- LHA vs. Encapsulated BHA for clogged pores: There is currently no reliable research directly comparing the effectiveness of Capryloyl Salicylic Acid (LHA) Liquid and Encapsulated Salicylic Acid (BHA) for treating clogged pores. LHA manufacturers suggest it has better absorption. The recommendation is to try one ingredient first, see if it works, and if not, or if you want to compare, try the other. You should evaluate which one is more effective and causes less irritation for your skin.
