Overview
Oxygen-based bleach, often referred to as 'explosive salt' in Chinese markets, is a versatile chemical compound widely used in laundry and cleaning applications. Composed of sodium percarbonate, it decomposes in water to release hydrogen peroxide and sodium carbonate, providing powerful oxidizing and cleaning effects. Unlike chlorine-based bleaches, it is environmentally friendly and safe for most fabrics. This compound is particularly popular in the textile and household cleaning industries due to its ability to remove tough stains, whiten fabrics, and disinfect surfaces without causing damage or leaving harmful residues. Its non-toxic nature and biodegradability make it a preferred choice for eco-conscious consumers and businesses.
Physical and Chemical Properties
Oxygen-based bleach appears as a white crystalline powder with a density of approximately 2.1 g/cm³. It is highly soluble in water, where it decomposes to release active oxygen, making it an effective cleaning and bleaching agent. The compound is stable under normal storage conditions but decomposes when exposed to moisture or high temperatures. Key chemical properties include its ability to oxidize organic stains and its pH-neutral behavior in solution, which prevents fabric damage. Unlike chlorine bleach, it does not produce harmful fumes and is safe for use with colored fabrics. These properties make it a versatile and user-friendly alternative for both industrial and household applications.
Main Applications
The primary use of oxygen-based bleach is in laundry detergents and stain removers, where it effectively tackles organic stains such as coffee, wine, and grass. It is also used in industrial textile processing to whiten and brighten fabrics without the harsh effects of chlorine. Additionally, it serves as a disinfectant in household and commercial cleaning products. In the B2B sector, oxygen-based bleach is procured in bulk by manufacturers of cleaning products, textile companies, and hospitality services. Its versatility and safety profile make it suitable for a wide range of applications, from hotel linens to medical laundry, ensuring high standards of hygiene and cleanliness.
Safety and Storage
While oxygen-based bleach is generally safe, proper handling and storage are essential to maintain its efficacy and prevent accidents. It should be stored in a cool, dry place in airtight containers to avoid moisture absorption, which can trigger premature decomposition. Direct contact with eyes or skin should be avoided, and protective gloves are recommended during handling. In industrial settings, bulk storage areas should be well-ventilated and free from acidic substances, as contact with acids can cause rapid decomposition and release of oxygen. Safety data sheets (SDS) should always be consulted for specific handling and emergency procedures to ensure compliance with workplace safety standards.
B2B Procurement Guide
When procuring oxygen-based bleach in bulk, businesses should prioritize suppliers who provide high-purity products (typically 85-95% sodium percarbonate). Purity levels directly impact the compound's effectiveness, so verifying certificates of analysis (CoA) is crucial. Bulk purchases often offer significant cost savings, with prices ranging from $2 to $5 per kg depending on quantity and supplier. Procurement professionals should also consider the supplier's reliability, packaging options (e.g., 25 kg bags or custom packaging), and logistics support. Establishing long-term contracts with trusted suppliers can ensure consistent quality and timely deliveries, which are critical for industries with high demand, such as textile manufacturing and commercial cleaning services.
