Question
Regarding a body lotion formulation for skin whitening, I have questions about specific ingredients:
- Can Perfect-C (Ascorbyl Tetraisopalmitate) be used to dissolve oxyresveratrol instead of other oil-soluble solvents?
- I intend to use Trans White (Tranexamic Acid) at 5%. Is this percentage acceptable?
- I am using multiple enzymes: Lemon Peel Bioferment, Pumpkin Renew, Papaya Enzyme, and Pineapple Enzyme. Are there any compatibility issues or recommended usage adjustments when combining these?
Answer
Regarding your lotion formula for skin whitening and the questions you asked, here is a summary of the feedback:
Ingredient Percentages and Adjustments:
- The staff noted that some ingredients, like Perfect-C, are expensive and typically used for facial products. For a body lotion covering a larger area, you might consider more cost-effective alternatives if budget is a concern.
- Trans White (Tranexamic Acid): The FDA maximum permitted concentration is 3% due to potential irritation at higher levels. Your formula uses 5%. It is strongly recommended to reduce the concentration to 3% or less.
- Enzymes (Lemon Peel Bioferment, Pumpkin Renew, Papaya Enzyme, Pineapple Enzyme): When using multiple types of enzymes together, it is advised to reduce the concentration of each individual enzyme. Using four different enzymes at the percentages listed might require significant reduction in each to avoid potential issues.
- Other ingredients and their percentages appear acceptable.
Using Perfect-C to dissolve oxyresveratrol:
- Perfect-C (Ascorbyl Tetraisopalmitate) is already in oil form. It does not need to be dissolved and can be added directly to the oil phase of your formulation.
In conclusion, please pay close attention to reducing the concentration of Tranexamic Acid and adjusting the concentrations of the enzymes if using multiple types. Perfect-C can be added directly to the oil phase.
