Mechanism of Action
Magnesium Lanolate functions via its magnesium ions, which are capable of permeating the stratum corneum, often facilitated by hair follicles. Once absorbed, magnesium can elevate skin hydration and significantly increase filaggrin levels, a protein vital for robust skin barrier function. It is hypothesized to support terminal epidermal differentiation through profilaggrin cleavage and may contribute to early wound healing by promoting cell migration while regulating epidermal differentiation. Additionally, it can enhance skin moisture by potentially upregulating Aquaporin 3 (AQP3) expression in keratinocytes.

Stability
Direct pH stability data for Magnesium Lanolate is not available. As an oil-soluble organic magnesium salt, it is expected to function well in nonaqueous systems. General magnesium salts can exhibit varied stability; some inorganic forms show poor stability at higher pH values (e.g., pH 8.5), while others, like Magnesium Laureth Sulfate, maintain foam stability in slightly acidic ranges (pH 3.5-4.0 and 5.5-6.0).
Conflicts
- While no specific incompatibilities are reported for Magnesium Lanolate, related magnesium salts, such as magnesium stearate, have demonstrated degradation when combined with strong acidic active pharmaceutical ingredients including aspirin, ibuprofen, lactic acid, and citric acid. This suggests a potential for instability with highly acidic components.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel evaluated Magnesium Lanolate as part of its safety assessment of fatty acids and their salts, affirming its safety for cosmetic use. Although precise maximum concentrations for Magnesium Lanolate were not detailed, the panel noted that magnesium salts typically do not induce sensitization. Related compounds, like Isopropyl Lanolate, and other magnesium salts such as magnesium sulfate (safe up to 11% in leave-on and 25% in rinse-off products), have also been deemed safe.
