Sodium Hypochlorite (Bleach)
Sodium hypochlorite (NaClO) is an alkaline chemical compound widely used as a broad-spectrum disinfectant and oxidizing agent in industrial cleaning applications. Commonly known as bleach, it is a clear, yellowish liquid with a characteristic pungent odor, typically supplied at concentrations ranging from 3% to 15% in aqueous solutions. Its powerful antimicrobial properties make it effective against bacteria, viruses, fungi, and spores, functioning through the release of hypochlorous acid (HClO) when dissolved in water, which disrupts cellular membranes and denatures proteins in microorganisms.
In the HORECA sector, sodium hypochlorite is essential for sanitizing food preparation surfaces, kitchen equipment, and utensils. Instaquim offers chlorinated products such as Clor NF Pro and Bacter Clor for the food industry; the compatible materials are stated in each technical data sheet. For laundry operations—both industrial and self-service—sodium hypochlorite effectively removes stubborn organic stains, brightens white textiles, and provides terminal disinfection.
In the food industry, sodium hypochlorite plays a critical role in water treatment, equipment disinfection, and facility sanitation. Its use is regulated under Regulation (EU) 528/2012 for biocidal products. The healthcare and sanitation sector relies heavily on sodium hypochlorite for disinfecting medical equipment, operating theaters, and patient care environments. It is particularly valued for its rapid action against COVID-19, influenza, and other nosocomial pathogens. In livestock facilities, it prevents disease transmission by sanitizing drinking water systems, housing areas, and equipment, reducing the need for antibiotic intervention.
The automotive industry utilizes sodium hypochlorite in parts cleaning and facility sanitation, where its oxidizing properties break down grease, oils, and biological contaminants.
Key considerations include proper dosage (typically 0.5–2% for disinfection), pH monitoring (effectiveness peaks at pH 6–8), and contact time requirements (5–10 minutes for full antimicrobial action). All Instaquim sodium hypochlorite products comply with REACH regulations; the efficacy of registered disinfectants such as Clor NF Pro (UNE-EN 1276, UNE-EN 13697) or Bacter Clor (UNE-EN 13697) is stated in their technical data sheets.
Safety protocols are essential: sodium hypochlorite must never be mixed with acids or ammonia-based products due to toxic chlorine gas evolution. Proper ventilation, personal protective equipment (gloves, eye protection), and appropriate storage in cool, dark conditions away from organic materials are mandatory. Instaquim provides comprehensive technical guidance and safety data sheets (SDS) for all formulations.
