Adding Panthenol (B5) for Hydration in Vitamin C Serum Formula
Question
I have the following Vitamin C serum formula:
Phase A
- Distilled Water: 43.7 g
- Triethanolamine (TEA): 2.5 g
- Ferulic Acid: 0.5 g
- Panthenol: 0.5 g
Phase B
- Ethoxydiglycol: 20 g
- Propylene Glycol: 10 g
- Glycerin: 3 g
- Laureth-23: 3 g
- d-Alpha Tocopherol: 1 g
- Phenoxyethanol (Optiphen): Amount not specified, but typically used as a preservative.
Phase C
- L-ascorbic acid: 15 g
Phase D
- Hyaluronic Acid Standard: 0.3 g
If I want to increase skin moisture, can I add Panthenol to 1-3% in this formula? Thank you.
Answer
Yes, you can increase Panthenol (Pro-Vitamin B5) in this Vitamin C Serum formula to help boost skin moisture.
Panthenol is a humectant and skin conditioning agent. Increasing the amount of Panthenol from 0.5g (approximately 0.5%) to 1-3g (which would be 1-3% in a formula weighing around 100g) can enhance the moisturizing benefits of the serum.
When adjusting the formula, you will need to reduce the amount of other ingredients to maintain the total proportion. Typically, the ingredient to reduce is Distilled Water to achieve the desired total weight.
However, modifying ingredient percentages can affect the stability and texture of the product. It is recommended to make a small test batch first and observe any changes in the serum's texture, clarity, and performance after use.
