Quaternium-73

Product Description

Quaternium-73 is a high-performance cationic surfactant produced in our state-of-the-art facility, ensuring industry-leading stability and effectiveness. It functions through a robust scientific mechanism of disrupting microbial cell membranes, specifically targeting Propionibacterium acnes with extremely low MIC values. As the global beauty market shifts towards clinical-grade "cleanical" solutions, Quaternium-73 has emerged as a premium gold-standard ingredient for high-efficacy anti-acne and blemish-control formulations.
