Overview

Proxel® LS Preservative is a broad-spectrum, formaldehyde-free in-can preservative developed by LANXESS to control microbial growth in water-based industrial products. Its primary active ingredient is 1,2-Benzisothiazolin-3-one (BIT), making it particularly effective against bacteria, mold, and yeast. Designed for low use levels, Proxel® LS is ideal for sensitive formulations requiring microbial stability without compromising compatibility or performance. It offers excellent pH stability and is compliant with many eco-label requirements, making it a preferred choice for modern, environmentally conscious applications.
