Proxel® BZ Plus is a high-performance, broad-spectrum in-can preservative designed for water-based industrial formulations susceptible to microbial contamination. Manufactured by LANXESS, it features a combination of 1,2-Benzisothiazolin-3-one (BIT) and 2-Methyl-4-isothiazolin-3-one (MIT) as its primary active ingredients, offering potent protection against bacteria, mold, and yeast. With no added formaldehyde or formaldehyde-releasing agents, it is ideal for environmentally conscious and eco-label compliant products. Proxel® BZ Plus is compatible with a wide range of surfactants, emulsifiers, and formulation types, and remains stable across a broad pH spectrum. Its high efficacy at low use levels, mild odor, and excellent stability make it a versatile preservative for demanding applications.
