How to Choose: Coated vs. Uncoated Sodium Percarbonate
Key Differences:
- For Stability: Coated sodium percarbonate offers superior storage stability, effectively resisting moisture and other detergent ingredients. The uncoated type is more sensitive to humidity.
- For Speed: Uncoated sodium percarbonate releases oxygen more rapidly, making it ideal for quick‑acting applications. The coated type releases oxygen more gradually.
- Main Use: Choose coated for laundry detergents, cleaning products, and formulations requiring extended shelf life. Choose uncoated for oxygen bleach powders or surfactant‑free products where fast action is needed.
Active Oxygen: Both types contain ≥13% active oxygen, ensuring strong bleaching performance.
Simple Selection Guide:
- Choose Coated Sodium Percarbonate when your product requires long‑term stability, such as in liquid detergents or formulations stored in humid environments.
Choose Uncoated Sodium Percarbonate when you need fast oxygen release and the product will be used within a short period, such as in bleaching powders or oxygen bleaches.
For your assurance, please contact HOO CHEMTEC to request our quality report, which confirms active oxygen content, moisture, and stability data for both coated and uncoated products.
Types of Sodium Percarbonate
| Feature | Sodium Percarbonate Granules | Sodium Percarbonate Tablets |
| Oxygen Release | Fast (within 0.5-1 hour). Ideal for quick action. | Slow & Sustained (up to 24 hours). For long-lasting, controlled release. |
| Active Oxygen | Higher. Greater oxygen potential per dose. | Lower. Due to slow-release ingredients. |
| Primary Use | Emergency aquaculture aeration, rapid pond oxygenation, cleaning/bleaching. | Long-term oxygenation for ornamental fish, sustained oxidation in water treatment. |
| Handling & Value | Cost-effective, dosed as needed, flexible use. | Convenient (toss-in), saves labor for long-term needs. |
- Laundry Detergent Industry: Sodium percarbonate is widely used as an oxygen bleach ingredient in powder detergents, laundry products, and cleaning formulations. It releases active oxygen to remove stains and improve whitening performance without chlorine residues.
- Industrial Cleaning: Sodium percarbonate provides an effective and environmentally friendly cleaning solution for removing grease, stains, and organic residues from industrial equipment and surfaces.
- Paper Bleaching: As a chlorine-free bleaching agent, sodium percarbonate helps improve pulp brightness while reducing the environmental impact associated with traditional chlorine-based bleaching processes.
- Water Treatment: Sodium percarbonate is used as an oxygen-releasing chemical for oxidation processes, helping improve water quality and control organic contaminants in certain water treatment applications.
- Aquaculture: Sodium percarbonate provides controlled oxygen release in aquaculture systems, helping increase dissolved oxygen levels and maintain a healthier aquatic environment.
FAQ of Sodium Percarbonate
Never mix sodium percarbonate with chlorine bleach (like bleach containing sodium hypochlorite) or strong acids (like vinegar). These combinations can produce toxic chlorine gas or cause a violent reaction.
For safe use, always follow these simple rules:
Use it alone.
Read the product instructions carefully first.
Wear gloves when handling.
No, baking soda and sodium percarbonate are not the same thing. They are two different chemicals with different uses.
Here are the key differences in simple terms:
Baking soda (sodium bicarbonate) is a mild, safe chemical mainly used in cooking, gentle cleaning, and deodorizing.
Sodium percarbonate is a strong oxidizing agent. When mixed with water, it releases hydrogen peroxide, making it a powerful bleach, stain remover, and disinfectant for laundry and cleaning.
Important: Unlike baking soda, sodium percarbonate requires careful handling and should never be mixed with acids or chlorine bleach.
In short, use baking soda for food and mild tasks. Use sodium percarbonate for tough stains and disinfecting.
It is considered a more environmentally friendly bleach. It breaks down into just oxygen, water, and soda ash (washing soda), leaving no harmful chlorinated residues.
For general cleaning, use it as needed for tough stains or monthly maintenance. For laundry, follow the specific product’s instructions on your detergent or stain remover package.
The active oxygen content of sodium percarbonate is typically 13.5%. HOO CHEMTEC supplies both coated and uncoated grades, with uncoated sodium percarbonate usually providing higher active oxygen content (≥13.5%) and coated grades offering improved storage stability.
Yes. HOO CHEMTEC provides COA (Certificate of Analysis), MSDS (Material Safety Data Sheet), and technical documents for sodium percarbonate upon request. We ensure product quality, specification compliance, and reliable support for global customers.
Packaging methods: 25kg/bag, drum, or bulk containers, customized according to customer requirements.
Sodium percarbonate should be stored in a cool, dry, well-ventilated place in its original sealed container, away from heat sources, sunlight, humid environments, acids, alkalis, flammable materials, and metals.
