Science
Mechanism of Action
This ingredient forms a superficial colloidal gel 'plug' within sweat pores upon contact with moisture, physically obstructing sweat release. The PEG component acts as a humectant and stabilizer, enhancing delivery and texture.

Stability
Highly stable in anhydrous systems; in aqueous solutions, it maintains stability within an acidic pH range of 3.0–5.0, with higher pH causing precipitation.
Conflicts
- Strong bases (alkaline ingredients)
- Anionic surfactants
- Soap-based emulsifiers
- Certain phosphates
Safety
Safety Profile
FDA limits use to 20% (anhydrous basis). Minimal dermal absorption (approximately 0.012%) is noted, but it should not be applied to broken skin or by individuals with kidney disease due to potential systemic aluminum accumulation.
