Quaternium-73

Synonyms: 1-(3-Chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride, CTAC, Quaternium-73, 3-Chloroallyl-1-azoniaadamantane chloride

In the personal care and industrial preservation markets, formulators are constantly seeking antimicrobial agents that deliver broad-spectrum efficacy without compromising product safety or stability. Quaternium-73 has emerged as a reliable choice for challenging preservation scenarios, particularly in wet wipes, cosmetics, and household products where traditional preservatives often fall short due to pH sensitivity or microbial resistance.

Chemically, Quaternium-73 is a quaternary ammonium compound with a unique cage-like adamantane structure. It is typically synthesized through the reaction of 1,3,5,7-tetraazaadamantane with 3-chloroallyl chloride, yielding a cationic surfactant with potent antimicrobial properties. This structure confers high reactivity and broad-spectrum activity against bacteria, fungi, and algae, making it effective at low concentrations.

LyvBio supplies Quaternium-73 with a minimum assay of 98.0% (HPLC), ensuring consistent performance in preservation systems. Our product is manufactured under strict quality control and is suitable for both leave-on and rinse-off applications, as well as industrial water treatment.

Product Overview & Composition

Quaternium-73 is a quaternary ammonium salt that functions as a cationic antimicrobial agent. Its mode of action involves disrupting microbial cell membranes and interfering with essential cellular processes, leading to rapid cell death. The compound is highly effective against a wide range of microorganisms, including Gram-positive and Gram-negative bacteria, yeast, and mold.

Due to its cationic nature, Quaternium-73 is compatible with nonionic and cationic surfactants but may be inactivated by anionic surfactants. It is stable over a broad pH range (4-10) and at elevated temperatures, making it suitable for diverse formulation conditions.

Key Applications

• Personal care preservation: Used in wet wipes, shampoos, lotions, and creams to prevent microbial growth and extend shelf life.
• Household products: Incorporated into disinfectants, fabric softeners, and hard surface cleaners for antimicrobial protection.
• Industrial water treatment: Applied as a biocide in cooling towers, paper mills, and oilfield water systems to control slime and biofouling.
• Cosmetics: Effective in emulsions and surfactant-based formulations, often combined with other preservatives for broad-spectrum coverage.
• Building materials: Added to paints, coatings, and adhesives to prevent microbial degradation.
