Science
Mechanism of Action
Functioning as a cationic surfactant, Lapyrium Chloride creates a protective layer that actively destroys harmful bacteria and inhibits their multiplication, thereby promoting skin hygiene. It contributes to skin cleansing by lowering surface tension to facilitate impurity removal and may help alleviate irritation stemming from external aggressors or excess sebum.

The Formula
Formulation
Stability
This compound is readily soluble in water and demonstrates excellent stability under typical conditions. It enhances product integrity by limiting microbial growth within the packaging. As a cationic surfactant, it forms micelles in aqueous solutions once its Critical Micelle Concentration (CMC) is reached.
Conflicts
- Formulations high in anionic compounds may compromise its solubility and antimicrobial efficacy due to strong interactions.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed Lapyrium Chloride safe for cosmetic use, a finding reconfirmed in 2007. While a 50% concentration under occluded conditions led to slight to moderate erythema on human skin, other tests indicated only very slight dermal irritation on both intact and abraded skin. Direct contact with the ingredient can provoke irritation to the skin or eyes. It is also listed by the FDA as an active ingredient in approved drug products.
