Science
Mechanism of Action
CI 77002 primarily functions by absorbing excess oil and impurities from the skin's surface, leading to a matte appearance. It establishes a thin, protective barrier that mitigates moisture loss and safeguards against environmental pollutants. This ingredient also helps balance the skin's pH by reducing acidity, offers mild exfoliation to clear pores, and delivers a soothing effect that can alleviate redness and irritation. Furthermore, it regulates oil production and serves as an emollient, humectant, opacifying agent, and viscosity controller. When applied as a coating for UV filters like Titanium Dioxide, it bolsters protection by preventing the generation of reactive oxygen species upon UV exposure.

The Formula
Formulation
Stability
CI 77002, as Aluminum Hydroxide, is an inorganic white powder exhibiting strong chemical and thermal stability, suitable for formulations requiring resistance to heat and light degradation. While insoluble in water, it disperses effectively in cosmetic and industrial systems. Stabilization is necessary during transportation and storage to prevent aggregation. It can have a drying effect on the skin.
Synergies
- UV filters (e.g., Titanium Dioxide) by protecting against reactive oxygen species.
Conflicts
- Retinoids
- Vitamin C
- AHAs (Alpha Hydroxy Acids)
- BHAs (Beta Hydroxy Acids)
Safety
Safety Profile
The CIR Expert Panel deems alumina and aluminum hydroxide safe for use at current concentrations. The SCCS has evaluated aluminum compounds, considering them safe at concentrations up to 6.25% in non-spray deodorants/antiperspirants, and 0.15%-5% for FDA-approved OTC skin protectants. It is listed as a restricted ingredient (IV/118a) in the European Cosmetics Regulation. Concerns linking aluminum compounds to Alzheimer's disease or breast cancer are not supported by conclusive scientific evidence.
