Replacing Hyaluronic Acid Powders with Double Hyaluron Liquid & pH Adjustment

Question

I previously used Hyaluronic Acid Standard and Hyaluronic Acid Nano powders in my formula. I want to replace both with Double Hyaluron Liquid. What is the recommended usage percentage for Double Hyaluron Liquid to substitute the two powders?

Also, my original formula used Triethanolamine (TEA) 2.5% for pH adjustment. Is this percentage appropriate, or what is the correct method to adjust the pH, especially considering the need for L-ascorbic acid stability (target pH 3.2-3.6)? Will replacing the powders with the liquid affect the texture (e.g., will it still form a gel)?

Formula Adjustment with Double Hyaluron Liquid

Based on your question and the staff's guidance, here's how to adjust your formula using Double Hyaluron Liquid:

Hyaluronic Acid Replacement: To replace both Hyaluronic Acid Standard and Hyaluronic Acid Nano, use 3% Double Hyaluron Liquid. This will substitute the amounts of both original hyaluronic acid powders (items 11 and 12) and require a reduction in the amount of Distilled Water (item 1) to keep the total formula at 100%.
Gel Texture: Double Hyaluron Liquid is a liquid and cannot create a gel texture in your formula.
Triethanolamine (TEA) Usage: The 2.5% concentration of Triethanolamine in your formula was noted by the staff as potentially high for pH adjustment. While you can use this amount if it matches your original source formula, the most accurate way to ensure the correct pH (ideally between 3.2-3.6 for L-ascorbic acid stability) is to add Triethanolamine gradually while measuring the pH with a pH Meter until the target range is achieved.

In summary, use 3% Double Hyaluron Liquid in place of the two hyaluronic acid powders and adjust the water. Be aware that this will not result in a gel texture. For the most stable formula, adjust the TEA based on pH measurement rather than a fixed percentage.
