  • Applications

    Quaternium 15 (CAS 4080-31-3) is primarily used as a formaldehyde-releasing preservative in cosmetics and personal care products to control microbial growth in items such as shampoos, lotions, and creams. It is also employed in household cleaning products and detergents as an antimicrobial preservative, helping extend shelf life and formulation stability. In some industrial formulations, it serves as an antimicrobial additive in coatings, inks, and adhesives, and it may be used in polymer dispersion systems where a preservative or biocidal function is needed. Use is subject to local regulations and formulation limits.
