Science
Mechanism of Action
It functions by contracting skin tissues, delivering an astringent effect, and may influence membrane permeability. In antiperspirant contexts, it likely forms temporary plugs within sweat ducts to reduce perspiration.

Key findings
- 01 Demonstrated low to no skin irritation in patch tests at concentrations up to 20%.
- 02 Investigated for its effect on membrane permeability in animal and human skin models.

Dusting Analysis
Though not specified as commonly dusted, inhalation poses a risk as it is noted as a sensitizing asthmagen; formulations must ensure it is non-inhalable.
The Formula
Formulation
Stability
Aqueous solutions are generally more stable than basic aluminum salts. Often formulated in hydroalcoholic or gel systems for enhanced stability.
Conflicts
- Metal ions (forms complexes)
- Strongly alkaline ingredients
- Anionic surfactants (may cause precipitation)
Safety
Safety Profile
While patch tests show low to no skin irritation, it is noted as a sensitizing asthmagen if inhaled. Rigorous formulation to prevent inhalation is critical.
