Suitability of Magnesium Sulfate in Facial Cleansing Foam
คำถาม
Can high-purity Magnesium Sulfate (Cosmetics Grade), typically used as an emulsion stabilizer in Water-in-Oil (W/O) formulations, be used in a facial cleansing foam, which is generally an Oil-in-Water (O/W) system, even if a homogeneous process is used?
คำตอบ
Based on the product information, Magnesium Sulfate (High Purity, Cosmetics Grade) is primarily used as an emulsion stabilizer in water-in-oil (W/O) formulations. The description explicitly states that it is not suitable for oil-in-water (O/W) formulas. Facial cleansing foams are typically oil-in-water systems. Therefore, this ingredient is likely not suitable for use in a facial cleansing foam, regardless of whether a homogeneous process is used, because the formulation type is generally incompatible with the ingredient's recommended application.
