  • Seeking Solutions to Mitigate the Sulphurous Smell of Glutathione in Emulsion

    Posted by Kaustav on November 6, 2023 at 3:56 am

    Currently, I am working on a project involving a Glutathione water-in-oil (W/O) emulsion. However, I have encountered an issue that I believe this esteemed community can help me address – the persistent sulphurous or rotten egg-like odor of Glutathione in my formulation.

    Allow me to share my formulation with you:

    Oil Phase:

    - Glyceryl monostearate: 5%

    - Medium chain triglyceride oil: 11%

    - Symdecanox HA (oil-soluble antioxidant): 2%

    - Emulium illistro: 7%

    - Olivatis 12C: 17%

    Water Phase:

    - Glutathione (active): 7%

    - Water: 42%

    - Lactic acid/Dexpanthenol (antioxidant): 5%

    - Disodium EDTA (Chelator): 1.5%

    - Natrlquest e30 (Chelator): 1.5%

    - Phenoxyethanol (preservative): 1%

    While this formulation provides the desired properties and benefits for skin care, the unpleasant odor from Glutathione is a concern. I am seeking your valuable insights and suggestions on how to effectively neutralize or reduce this unwanted smell without compromising the product’s efficacy.

    If you have any experience or expertise in dealing with odor issues in cosmetic formulations, please share your knowledge and recommendations. Your contributions will greatly assist in the success of this project and the development of a high-quality cosmetic product.

    @Kaustav try adding zinc citrate to this. That can subdue thiol related odors.
