How to Use Hyaluronic Acid (Japan) Powder in Gel Formulation
Question
How should Hyaluronic Acid (Japan) powder be correctly calculated and incorporated into a gel formulation at a specific concentration (e.g., 1% in 500g), and is it necessary to pre-dissolve the powder in a small amount of water before adding it to the main formula?
Answer
The calculation for the amount of Hyaluronic Acid (Japan) needed in a 500g gel formula at a concentration of 1% is correct. You need 5 grams of Hyaluronic Acid (Japan) (500g * 1% = 5g).
Regarding the method of use, it is not correct to dissolve 1g in 99g of water first and then use 5g of that solution. The 1% concentration refers to the weight of the Hyaluronic Acid (Japan) powder in the total formula weight. You need 5g of the powder in the 500g final formula.
The correct method is:
- Weigh out 5 grams of Hyaluronic Acid (Japan) powder.
- Add this 5 grams of Hyaluronic Acid (Japan) powder directly into the water phase of your 500g gel formula.
- Stir or blend in room temperature water until the powder is completely dissolved and forms a gel. This type of Hyaluronic Acid (Japan) dissolves more easily than others and can be stirred by hand until clear, taking about 15 minutes.
In summary, you should use 5 grams of Hyaluronic Acid (Japan) powder in your total 500g formula by dissolving the powder directly into the water phase, without making a pre-solution first.
