A large release of NALCO® 77225 will cause a spike in the pH of soil or localized waterways, endangering aquatic life.

The SDS provides information on toxicological effects: nalco 77225 safety data sheet 2021

Under Regulation (EC) No 1272/2008 (CLP), Nalco 77225 is classified as a hazardous mixture:

NALCO 77225 is formulated as an internal boiler feedwater treatment designed to prevent scale formation. It integrates a complex phosphate residual program with proprietary Transport Plus polymer technology. This blend allows the treatment to successfully react with calcium and magnesium hard water ions while suspending iron, silica, and phosphate molecules so they do not adhere to boiler tubes up to operational pressures of 40 barg. Material Compatibility Constraints

According to the SDS, Nalco 77225 is a:

The 2021 SDS for Nalco 77225 (generally described as a corrosion inhibitor for industrial water treatment ) is largely compliant with GHS/OSHA standards. It provides strong hazard communication for acute toxicity and dermal corrosion but falls short on environmental fate data, a common industry shortfall.

Nalco 77225 is engineered for low-hardness, softened, or dealkalized water systems operating in boilers with pressures reaching up to . It handles two primary operational functions:

Personnel interacting with the chemical must track its basic properties to safely identify, feed, and manage it within thermal systems. As documented in Section 9 of the Nalco 77225 GHS SDS , its core traits include: Value / Specification Color Odor Ammoniacal (ammonia-like smell) pH (100%) 13.5 (Highly alkaline) Relative Density 1.46 – 1.50 at 25 °C Freezing Point -19.9 °C (-3.8 °F) Flash Point Does not flash (Not flammable) Water Solubility Completely soluble Dynamic Viscosity 8 – 16 mPa.s at 25 °C Safety and Handling Protocols Understanding the Nalco 77225 Safety Data Sheet (SDS)
