Science
Mechanism of Action
This ingredient functions as a cationic surfactant, characterized by a positive charge that allows it to electrostatically bind to negatively charged surfaces, such as compromised skin or hair keratin. This adsorption process forms a substantive, durable film that delivers conditioning and softening benefits. Additionally, it mitigates static electricity and exhibits antimicrobial activity by hindering or eliminating microbial proliferation.

Stability
Steapyrium Chloride contains an ester linkage, rendering it susceptible to hydrolysis, which can complicate the formulation of stable aqueous solutions. Its stability is critically dependent on pH and temperature; it remains stable in acidic environments and formulations up to a pH of 6.0. Degradation is observed in alkaline solutions.
