Introduction：Quaternium-73, also known as Pionine, is a highly effective antibacterial ingredient commonly used in Japanese over-the-counter (OTC) acne treatment products, such as Kobayashi's anti-acne first aid stick. It appears as a yellow, odorless crystalline powder with excellent stability and broad-spectrum antimicrobial properties, delivering potent effects even at low concentrations. Due to its remarkable antibacterial efficacy, Quaternium-73 is widely incorporated into cosmetics and personal care products to enhance product stability and safety.

Properties：Quaternium-73 is renowned for its outstanding antibacterial properties, effectively inhibiting acne-causing bacteria such as Propionibacterium acnes, Staphylococcus aureus, and Escherichia coli, helping to prevent and alleviate breakouts. In addition to its antimicrobial function, it serves as a preservative with superior performance compared to traditional parabens.

Furthermore, Quaternium-73 has the ability to suppress melanin production, contributing to a brighter and more even skin tone. As a result, it is frequently included in acne-fighting, brightening, and preservative formulations, promoting clear and healthy skin.
