Description

Quaternium-15 is a well-established quaternary ammonium compound widely recognized for its efficacy as a preservative. Its primary value lies in its potent antimicrobial activity, which effectively inhibits the growth of bacteria, yeast, and mold in aqueous formulations. This makes it a critical component for manufacturers in the personal care, cosmetic, and industrial sectors who require reliable, broad-spectrum protection for their products.

Application

• Cosmetic & Personal Care Preservative: A key ingredient in shampoos, conditioners, liquid soaps, creams, lotions, and other water-based formulations to prevent microbial spoilage.
• Industrial Fluid Protection: Used in metalworking fluids, adhesives, latex emulsions, and polymer dispersions to extend shelf life and maintain product integrity.
• Household & Institutional Products: Incorporated into cleaning solutions, fabric softeners, and dishwashing liquids for microbial control.
• Paints & Coatings: Acts as an in-can preservative in water-based paints and coatings to prevent bacterial degradation.
• Pharmaceutical Adjuvant: Employed in certain topical pharmaceutical preparations as a preservative agent.
