: Works effectively in systems with high pH, where many other biocides lose their potency. Safety & Hazard Information
When handling high-performance biocides, accessing a verified Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) is essential for regulatory compliance, environmental safety, and workplace accident prevention. Industrial facilities must acquire these verified data sheets directly through official channels like the Ecolab Nalco Water SDS Request Portal to ensure the documentation reflects the most up-to-date regional chemical safety regulations. 1. Verified Physical & Chemical Properties
The high concentration of glutaraldehyde makes the product a potent biocide, while methanol serves as a stabilizer. This combination explains the product’s strong pungent odor and its hazardous properties.
