Question
In the provided cream formulation, where should Niacinamide (Vitamin B3) and other whitening agents be added (water or oil phase), and what are the recommended usage percentages?
Answer
Regarding adding Niacinamide (Vitamin B3) and other whitening agents to your cream formulation:
- Niacinamide (Vitamin B3): This ingredient is water-soluble.
- Phase: You should add Niacinamide to the water phase ("ส่วนของน้ำ").
- Percentage: For skin brightening effects, Niacinamide is typically used at concentrations between 2% to 5%. You can adjust the percentage of water in the water phase accordingly to accommodate the added Niacinamide while keeping the total water phase at 100%. Higher concentrations (e.g., up to 10%) are sometimes used but may increase the risk of skin irritation.
- Other Whitening Agents: If you plan to add other whitening agents, their solubility (water or oil) and recommended usage rates will vary depending on the specific ingredient. Always check the supplier's recommendations for each ingredient.
