คำถาม
My custom cream formulation, containing ingredients like Glutathione and DMAE, has an unpleasant odor. What specific ingredient(s) are likely causing this smell, and what steps can be taken to resolve or mitigate the odor issue?
คำตอบ
Subject: Regarding the odor issue in your custom cream formulation.
Based on the ingredients you listed, the most likely culprits for the unpleasant smell in your cream are Glutathione (L-Glutathione) and DMAE (Dimethylaminoethanol).
- Glutathione is a sulfur-containing compound and is well-known for having a distinct sulfurous odor, sometimes described as similar to rotten eggs or body odor.
- DMAE is an amine and can have a characteristic fishy or amine-like smell.
Other ingredients could potentially contribute if they are impure, degraded, or interacting in an unusual way, but Glutathione and DMAE are the most common sources of strong, unpleasant odors in cosmetic formulations containing them.
To address this issue, you could consider the following:
- Check the quality and source of your Glutathione and DMAE. Ensure they are high purity and stored correctly. Degradation of these ingredients can worsen the smell.
- Review the formulation's pH. Sometimes the odor of ingredients like DMAE can be more pronounced at certain pH levels.
- Ensure proper storage of the finished cream (cool, dark place) to prevent degradation.
- Consider adding a fragrance to mask the odor, although this doesn't eliminate the source.
- Consult with the formulator or supplier who produced the cream. They may have specific knowledge about the ingredients used and potential solutions.
