Quaternium-15 CAS#4080-31-3
Broad-Spectrum Antimicrobial Activity – Effectively inhibits the growth of bacteria, fungi, and yeast, ensuring long-term product stability.
Versatile Usage – Widely used as a preservative in cosmetics, personal care products, and industrial formulations.
Cost-Effective – Provides reliable antimicrobial protection at a relatively low cost.
Controlled Formaldehyde Release – Its chemical structure allows slow-release biocidal action while also functioning as a cationic surfactant.
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 functions by releasing formaldehyde to inhibit microbial growth, helping to maintain product shelf stability. Known for its broad-spectrum activity against bacteria, fungi, and yeast, it is a cost-effective solution, although safety concerns exist due to potential skin sensitization and formaldehyde release (regulated at ≤0.2% in the EU under Cosmetic Directive 76/768/EEC). Its chemical structure combines a quaternary nitrogen with a chlorallyl group, providing both cationic surfactant properties and controlled, slow-release biocidal activity.
