In the world of industrial water treatment, Nalco Water (an Ecolab company) is a leading name, known for its advanced chemical formulations. Among its extensive product portfolio is , a specialized chemical used primarily for boiler water treatment, scale inhibition, and corrosion control in high-pressure steam systems. However, with the utility of this chemical comes significant responsibility. The Material Safety Data Sheet (MSDS) —now more commonly referred to as the Safety Data Sheet (SDS) under the Globally Harmonized System (GHS)—is the single most critical document for anyone handling, storing, or transporting this substance.
It typically contains a mixture of Isothiazolinones (such as 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one). nalco 77352 msds
Under normal conditions, respiratory protection is rarely required. If workplace exposure limits are exceeded or if aerosol/mist generation occurs, use an approved air-purifying respirator. Summary of Physical and Chemical Properties
Causes irreversible eye damage, chemical skin burns, and severe allergic skin reactions. It is also highly toxic to aquatic environments.
It remains effective even at higher pH values and in the presence of organic matter. Health and Safety Hazards Keep in a well-ventilated, cool area and protect
Stability and reactivity
To minimize the risk of exposure, specific personal protective equipment must be worn when handling NALCO 77352:
Causes severe skin chemical burns. Prolonged exposure can trigger severe allergic skin sensitization. Inhalation Solubility: Completely soluble in water
The biocidal action comes from a mixture of 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one , with a CAS Number of 55965-84-9.
