✅ Overview

Mergal® 142 is a formaldehyde-free, broad-spectrum in-can preservative developed by Arxada (formerly Troy Corporation) for safeguarding water-based industrial products against microbial spoilage. This preservative features a highly effective combination of 1,2-Benzisothiazolin-3-one (BIT) and other isothiazolinone-based actives, designed to inhibit the growth of bacteria, fungi, and yeasts. Known for its excellent compatibility, low odor, and stability over a wide pH range, Mergal® 142 is ideal for environmentally conscious formulations that require long-term protection without compromising on regulatory compliance or application integrity.
