Under GHS, NALCO 77225 carries the icon (depicting chemical pouring onto hands and materials) and the Exclamation Mark icon (signaling acute oral toxicity). Key Physical and Chemical Properties
Understanding the baseline characteristics of NALCO 77225 ensures that safety personnel can isolate and mitigate unintended exposures or material degradation. Value / Specification Color Clear colorless to light yellow Odor Ammoniacal (Mildly pungent) pH (Pure) Freezing Point -19.9 °C (-4 °F) Flash Point Does not flash / Non-flammable Water Solubility Completely miscible Dynamic Viscosity 8 – 16 mPa·s at 25 °C 3. Material Compatibility & Storage Requirements
If a direct exposure event occurs, response speed determines the severity of the outcome. First-aid providers should execute immediate actions according to the GHS response protocols: nalco 77225 safety data sheet 2021
A proprietary organic polymer disperses calcium, magnesium, iron, phosphate, and silica, ensuring these compounds remain mobile and are successfully removed via routine boiler blowdown. Core Physical and Chemical Properties
This article dissects the 2021 SDS into its 16 mandatory sections, explaining what each means for plant operators, maintenance crews, and EHS (Environment, Health, and Safety) managers. Under GHS, NALCO 77225 carries the icon (depicting
Section 9 of the maps out the distinct physical hallmarks of the liquid concentrate, highlighting its corrosive and highly alkaline properties: Value / Description Physical State Color Colorless to Light Yellow Odor Distinctly Ammoniacal (ammonia-like) pH (100% Concentrate) 13.5 (Extremely alkaline) Freezing Point -19.9 °C (-3.8 °F) Flash Point None (Does not flash; non-flammable liquid) Relative Density 1.46 – 1.50 at 25 °C Water Solubility Completely soluble Dynamic Viscosity 8 – 16 mPa.s at 25 °C 4. Stability, Reactivity, and Incompatibility
Due to its high pH of 13.5, the solution can inflict rapid, irreversible chemical burns on living tissues. Implementing standardized engineering controls and personal protective equipment (PPE) mitigates these operational risks. Material Compatibility & Storage Requirements If a direct
