For professionals in the chemical and manufacturing industries, a thorough understanding of the materials they work with is crucial. Octylisothiazolinone (OIT), with its CAS number 26530-20-1, is a widely used biocide valued for its effectiveness. Whether you are a research scientist, a production manager, or a procurement specialist looking to buy OIT, familiarizing yourself with its properties and handling requirements is key to safe and efficient utilization.

Key Properties of Octylisothiazolinone (OIT)
OIT is characterized by its specific physical and chemical attributes that dictate its performance and application suitability. As a leading manufacturer and supplier, we highlight the essential properties:

  • Appearance: OIT typically presents as a light yellow liquid. This visual characteristic is an initial indicator of product identity and purity.
  • Assay: A high assay, commonly 98% minimum, is critical for ensuring potent antimicrobial activity. This purity level guarantees that the biocide will perform as expected in industrial formulations.
  • Molecular Formula and Weight: Its molecular formula is C11H19ONS, with a molecular weight of approximately 213.34 g/mol. These parameters are important for stoichiometric calculations in formulations.
  • Solubility: OIT is generally soluble in many organic solvents and has limited solubility in water, which influences its application in different media, particularly in water-based systems where emulsification or dispersion may be required.
  • Stability: Under recommended storage conditions, OIT is stable. However, like many active chemicals, it can degrade under extreme temperatures, pH, or in the presence of incompatible substances.

Safe Handling and Storage Practices
The responsible use of OIT necessitates adherence to strict safety protocols. As a biocide, it is designed to be toxic to microorganisms, and therefore, appropriate precautions must be taken by humans.

  • Personal Protective Equipment (PPE): When handling OIT, it is imperative to wear appropriate PPE, including chemical-resistant gloves, eye protection (safety goggles or face shield), and protective clothing. Respiratory protection may be necessary in areas with poor ventilation or potential for aerosol generation.
  • Ventilation: Ensure adequate ventilation in work areas where OIT is handled or stored. Local exhaust ventilation is recommended to control airborne concentrations.
  • Storage: OIT should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and sources of ignition. Containers should be kept tightly sealed to prevent contamination and evaporation. Recommended storage temperatures are often in the range of 2-8°C for long-term stability, though specific guidelines from the supplier should always be followed.
  • Incompatibility: Avoid contact with strong oxidizing agents, strong reducing agents, and strong bases, as these can lead to hazardous reactions or degradation of the product.
  • Spill Response: In case of spills, contain the material immediately and use appropriate absorbent materials. Dispose of contaminated materials according to local environmental regulations. Always consult the Safety Data Sheet (SDS) for detailed spill response procedures.

For procurement managers and formulators looking to buy OIT, understanding these properties and handling requirements is as important as the price and availability. Partnering with a reliable manufacturer and supplier ensures that you receive high-quality OIT along with comprehensive safety data and guidance, promoting safe and effective use in your industrial processes.
