What Is Sodium Percarbonate?
Sodium percarbonate or sodium peroxocarbonate, is a compound of sodium carbonate and hydrogen peroxide. This white crystalline powder dissolves in water and is a powerful oxidizing agent. Sodium percarbonate poses a risk of fire or explosion upon contact with water, especially above 50°C.
Its efficacy as a non-chlorine bleach has made it a preferred choice in various cleaning applications, offering an environmentally friendly alternative to traditional chlorine-based products.
Uses of Sodium Percarbonate
Utilized for its bleaching, disinfecting, and deodorizing properties, sodium percarbonate is employed in both household and industrial settings.
1. Bleaching Agent
Effectively bleaches fabrics and garments without damaging fibers or producing harsh odors, unlike chlorine bleach.
2. Cleaning Agent
Cleans residential surfaces, piping, and medical equipment, offering a versatile cleaning solution.
3. Disinfectant Bleach Cleaning Agent
Used for sanitizing diapers and dentures, ensuring hygiene in sensitive applications.
4. Industrial Treatment Agents
Acts as a textile bleacher, pollution control agent, and semiconductor manufacturing cleaner. Additionally, it serves as an emergency oxygen gas generator and hair dye oxidizing agent.
Properties of Sodium Percarbonate
Stable at room temperature, this odorless powder forms an alkaline solution upon dissolution, showcasing strong oxidizing capabilities.
Reacts with various materials, necessitating careful handling and storage away from flammable and reducing substances, and certain metals.
Structure of Sodium Percarbonate
The compound features two sodium ions linked to a carbonate and hydrogen peroxide, highlighting its ionic and oxidizing nature.
Other Information on Sodium Percarbonate
1. Production Methods
Produced via wet or dry processes, with stabilization often achieved by salts to remove impurities or as chelating agents.
2. Common Uses
Marketed as a superior cleaning agent, effective against stubborn stains and discolorations, compared favorably to other household cleaners for its higher pH and efficacy.
3. Comparison with Sodium Peroxide
Distinguished from sodium peroxide by its safety profile and application, sodium percarbonate offers a less reactive, more user-friendly option for cleaning and bleaching.
