Dissolving Hyaluronic Acid Standard and Usage Percentage
Question
Regarding Hyaluronic Acid Standard:
1. What is the correct method to dissolve Hyaluronic Acid Standard powder in a formula to prevent clumping?
2. Is 0.5% concentration of Hyaluronic Acid Standard too high for a cosmetic formula, specifically concerning texture and absorption?
Answer
Regarding the issue with dissolving Hyaluronic Acid Standard in your C E Ferulic formula:
It is common for Hyaluronic Acid Standard (higher molecular weight) to be difficult to dissolve compared to the Nano type, and it tends to form clumps ("fish eyes") if not dissolved correctly.
Based on the staff's advice and general practice, Hyaluronic Acid powder should be dissolved while the formula is very cold. It is crucial to slowly sprinkle the powder in very small amounts while stirring continuously and vigorously to prevent clumping. Adding it to a warm mixture or adding it too quickly can cause stubborn clumps that are hard to dissolve later, even with subsequent stirring or chilling.
Therefore, the recommended method is to mix parts A, B, and C, then let the mixture cool down completely (chilling can help). While stirring the cold mixture, slowly sprinkle in the Hyaluronic Acid Nano until dissolved, then slowly sprinkle in the Hyaluronic Acid Standard in very small increments while continuously stirring. It may require significant stirring time for complete dissolution.
Regarding your second question about whether 0.5% Hyaluronic Acid Standard is too much: According to the MySkinRecipes staff, 0.5% is considered too high for normal skin. This concentration of Hyaluronic Acid Standard can feel sticky and may not absorb well. If you find the texture uncomfortable, you might consider reducing the amount of Hyaluronic Acid Standard in future batches for a more pleasant feel on the skin.
Hope this helps!
