Sodium hypochlorite is a chemical compound with the formula NaOCl, commonly used as a bleaching agent and disinfectant. It is the active ingredient in many household bleaches and is typically available as a clear, slightly yellowish solution.

How it works as a bleach:

• Oxidation: Sodium hypochlorite works by releasing chlorine, which acts as a powerful oxidising agent. When it comes into contact with stains, dirt, and microorganisms, the chlorine breaks down their chemical bonds through oxidation, effectively destroying them.
• Disinfection: The chlorine released from sodium hypochlorite also has strong antimicrobial properties. It disrupts the cell walls of bacteria, fungi, and viruses, leading to their inactivation and death. This makes sodium hypochlorite an effective disinfectant for sanitising surfaces and water.
• Whitening: The oxidative power of sodium hypochlorite breaks down color-causing molecules in stains, such as those found in organic materials like food, drink, and bodily fluids. This process not only removes the stains but also whitens the fabric or surface being treated.

True Blue Bleach 4%, like most chlorine-based bleaches, is primarily designed for whitening and sanitising applications and is generally not safe for coloured fabrics. The powerful bleaching agents, such as sodium hypochlorite, can strip the colour from fabrics, leading to fading or discolouration.
