คำถาม
Based on the usage instructions:
- Recommended concentration is 5%.
- Maximum concentration is 10% without causing allergy or skin irritation.
Given an example of adding Vitamin B3 5% per 100g total weight, if making 1000g of cream or lotion, how many grams of Vitamin B3 should be added? Thank you.
คำตอบ
Based on your question, if you are making 1000g of cream or lotion and want to maintain a 5% concentration of Vitamin B3 (Niacinamide), you would need to calculate 5% of the total weight.
Calculation:
5% of 1000g = (5 / 100) * 1000g = 0.05 * 1000g = 50g
So, you would need to add 50 grams of Vitamin B3 to 1000g of cream or lotion base to achieve a 5% concentration.
