Quaternium-15
Products Description of Quaternium-15 CAS#4080-31-3
Quaternium-15 (CAS 51229-78-8) is a quaternary ammonium compound, widely used as a preservative and antimicrobial agent in cosmetics, personal care products (such as shampoos and lotions), and industrial formulations. It works by releasing formaldehyde to inhibit microbial growth, thus ensuring the shelf stability of products. It is known for its broad-spectrum effectiveness against bacteria, fungi, and yeast, and is cost-effective. However, it has raised safety concerns due to potential skin sensitization and formaldehyde release—its content is regulated to be ≤0.2% in the EU and is restricted under the Cosmetic Directive 76/768/EEC. Its chemical structure integrates a quaternary nitrogen and a chlorallyl group, which gives it both cationic surfactant properties and slow-release biocidal effects.
