Question

I want to add Glycerin 5% and Vitamin C 2% to lavender water. Can I add Vitamin C L-ascorbic acid directly to water? What are the stability issues, and what alternatives are available?

Answer

Hello,

Regarding your question about adding Glycerin 5% and Vitamin C 2% to lavender water:

  • Glycerin 5%: Glycerin at 5% can generally be added to water-based formulations like lavender water. Glycerin is water-soluble and acts as a humectant.
  • Vitamin C 2%: As the staff response correctly points out, Vitamin C in the form of L-ascorbic acid is not stable when added directly to water. It degrades quickly.

If you want to add Vitamin C to a water-based product like lavender water, please consider using more stable derivatives such as:

These forms are designed to be stable in water. You can check the product details pages for more information on the stability and usage of each type of Vitamin C.
