Science
Mechanism of Action
This compound acts as an antimicrobial agent by effectively suppressing the proliferation of various microorganisms, including bacteria, fungi, and viruses, thereby promoting a cleaner skin environment. Its chelating ability allows it to bind undesirable metal ions, such as calcium and magnesium, preventing destabilizing reactions and potentially improving the bioavailability of other active components. As a humectant, it facilitates the absorption of water into the stratum corneum, significantly reducing trans-epidermal water loss and preventing dehydration. Furthermore, it functions as a deodorant by mitigating unpleasant odors and as an opacifying agent to impart desired product opacity. It also contributes to product integrity as a UV-absorber, shielding formulations from ultraviolet degradation.

Stability
Specific optimal pH stability data for the complex SODIUM/ALUMINUM/IRON/SULFATE/OXALATE/HYDROXIDE is currently unavailable. Its inherent chelating function implies it binds metal ions, which can influence the stability and quality of cosmetic products. Studies on individual components indicate that iron exhibits insolubility at pH values exceeding 5.5, while some iron-oxalate complexes maintain stability within the pH range of 1-2. Aluminum sulfate, another constituent, typically yields aqueous solutions with a pH of 2.9 or higher (for a 5% solution). The solubility of sodium oxalate increases linearly with rising temperatures.
Safety
Safety Profile
There is currently no specific safety assessment by the Cosmetic Ingredient Review (CIR) Expert Panel, SCCS, or FDA for the exact complex SODIUM/ALUMINUM/IRON/SULFATE/OXALATE/HYDROXIDE. However, some of its constituent compounds have been reviewed. Alumina and aluminum hydroxide have been deemed safe by the CIR Expert Panel for current cosmetic uses and concentrations. The FDA generally recognizes aluminum hydroxide and aluminum sodium sulfate as safe (GRAS) for specific food applications. It is important to note that aluminum in general can interact with biological processes, potentially inducing cellular oxidative stress and affecting calcium metabolism, with neurotoxicity being a recognized concern. The classification and restriction of such aluminum-containing compounds are reported to be under ongoing review.
