About
An inorganic salt complex of azelaic acid with aluminum and magnesium that acts as an emulsion stabilizer and viscosity controller in cosmetic formulations.
Aluminum/Magnesium Azelate Hydroxide is the reaction product of azelaic acid (a naturally occurring dicarboxylic acid) with magnesium chloride, aluminum chloride, and sodium hydroxide, producing a mixed metal salt with viscosity-controlling and emulsion-stabilizing properties. Azelaic acid itself is approved in the EU up to specific concentrations in cosmetic products for its skin-brightening and anti-blemish effects. The aluminum/magnesium complex is not restricted under EU Regulation 1223/2009 Annexes II or III. The ingredient is considered chemically stable and non-reactive at cosmetic pH ranges.
Function
Skin benefits
- Emulsion stabilizing properties ensure consistent cosmetic texture and product performance
- Viscosity-controlling action contributes to product texture and stability
Known concerns
- Contains aluminum; topical aluminum exposure is subject to ongoing scientific review, though no EU restrictions apply to this specific ingredient
- Mixed-metal salt may be incompatible with strongly acidic formulations
