Science
Mechanism of Action
This ingredient functions by significantly lowering the surface tension of water, facilitating the emulsification of oils and debris. Its amphiphilic molecular structure possesses an oil-loving segment that binds to impurities and a water-loving segment that aids in their efficient rinse-off, thereby ensuring thorough cleansing and consistent lather formation.

Stability
Exhibits excellent foaming stability across a broad pH range of 3.5 to 7.5, making it suitable for a diverse array of cosmetic applications.
Conflicts
- Elevated concentrations of specific ions, including chlorine, calcium, and magnesium, in water can potentially diminish its thickening efficacy.
- Potential for trace contamination with Ethylene Oxide and 1,4-Dioxane may occur during the manufacturing process, necessitating stringent quality control measures.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed related sulfated ethoxylated alcohols, which encompass Magnesium Laureth-5 Sulfate, safe for use in cosmetics under the condition that they are formulated to be non-irritating. While CIR did not specify a maximum concentration for this particular ingredient, careful formulation is crucial to mitigate potential irritation. It is important to note that this ingredient is distinct from Magnesium Sulfate (MgSO4), which carries different FDA classifications.
