Adjusting Usage Percentage for New LHA Product with Higher Concentration
Question
If I previously used 5% of the old product `Capryloyl Salicylic Acid (LHA) Liquid` (which contains 10% active LHA), how much of the new product `Capryloyl Salicylic Acid (LHA) EZ™` (which contains 20% active LHA) should I use to achieve the same concentration of active LHA in my formula?
Answer
Based on the information provided, the previous liquid LHA product you used had 10% active LHA, and the new Capryloyl Salicylic Acid (LHA) EZ™ product has 20% active LHA.
To maintain the same concentration of active LHA in your formula, you need to adjust the percentage of the new product.
- If you previously used 5% of the old product (which contained 10% active LHA), the amount of active LHA in your formula was 5% * 10% = 0.5%.
- To get 0.5% active LHA using the new product (which contains 20% active LHA), you should use 0.5% / 20% = 2.5% of the new Capryloyl Salicylic Acid (LHA) EZ™ product.
Therefore, you should use 2.5% of the new Capryloyl Salicylic Acid (LHA) EZ™ product in your formula to achieve the same active LHA concentration as using 5% of the old liquid LHA product.
