For manufacturers and formulators working with L-Glutathione Reduced powder, understanding its handling and optimal usage is key to achieving superior product efficacy. This versatile cosmetic raw material is soluble in water, making it relatively easy to incorporate into various aqueous-based formulations such as serums, lotions, and cleansers. The maximum recommended concentration for cosmetic use typically ranges from 0.1% to 0.6%, though this can vary based on the specific product and desired outcome. Stability is a crucial consideration; L-Glutathione remains most stable under a pH range between 3.5 and 6.6. To further enhance its stability and efficacy, adding chelators to formulations is often recommended, as L-Glutathione can be susceptible to oxidation. When adding to formulations, it is best to incorporate it during the cool-down phase or at room temperature.
