Answer
It is common for Vitamin C E Ferulic formulations to have a distinct odor, often described as metallic or like "hot dog water," which comes from the active ingredients themselves, particularly the L-Ascorbic Acid and Ferulic Acid.
To reduce or mask this odor, you can add a small amount of fragrance or a specific masking agent designed for cosmetic formulations.
- Fragrance: Adding a fragrance is the most common method to cover up the inherent smell. Choose a fragrance that is stable in acidic environments, as Vitamin C serums typically have a low pH. Start with a very low concentration (e.g., 0.1-0.5%) and adjust as needed. Be aware that some fragrances can cause sensitivity in certain individuals.
- Masking Agent: Masking agents are ingredients specifically designed to neutralize or reduce unpleasant odors without adding a noticeable scent of their own. These work by chemically reacting with or absorbing the odor molecules.
When adding any new ingredient, especially fragrance, it's important to test for stability and potential interactions with the active ingredients over time.
