Sodium Percarbonate SPC Sodium carbonate peroxide CAS 15630-89-4

Tree Chem Sodium Percarbonate (SPC) combines sodium carbonate and hydrogen peroxide in a crystalline adduct form. Upon dissolution, it releases hydrogen peroxide and sodium carbonate, delivering powerful yet environmentally safe oxidation. With high active oxygen (≥ 13 %) and low drying loss (≤ 2 %), it ensures efficient performance across detergent, textile, and paper-bleaching applications.

Available in granular and tablet types, Tree Chem SPC is suitable for automatic washing systems, oxygen-based detergents, and industrial cleaning processes. Its high stability (≥ 90 %) and moderate pH (10–11 at 30 g/L) make it a preferred non-chlorine oxidizing and whitening agent for both household and professional uses.

Applications

Detergent and Cleaning Industry

• Sodium Percarbonate is a key active oxygen bleaching agent widely used in household and industrial cleaning formulations. When dissolved in water, it releases hydrogen peroxide and oxygen, providing powerful oxidation for stain removal. It effectively decomposes and removes stubborn organic stains such as tea, coffee, blood, and grease. In modern laundry detergents and dishwashing powders, SPC replaces chlorine-based bleaches, ensuring bright colors and fabric protection. It also enhances cleaning performance in low-temperature washing and improves the long-term stability of detergent formulations.

Textile and Paper Industry

• In textile processing, Sodium Percarbonate serves as an eco-friendly bleaching agent for cotton, linen, and synthetic fabrics. It provides high whiteness without causing fiber damage, making it ideal for pre-treatment and desizing processes. It is also used in continuous and batch bleaching systems due to its stable oxygen release and minimal yellowing effect. In the paper industry, SPC is employed in pulp bleaching, deinking recycled paper, and improving brightness. It replaces sodium hypochlorite, reducing environmental pollution and improving fiber quality for high-grade paper production.

Water Treatment and Environmental Protection

• Sodium Percarbonate is an effective oxidizer for wastewater purification and environmental restoration. It decomposes into sodium carbonate and hydrogen peroxide, producing reactive oxygen species that oxidize organic pollutants, phenols, sulfides, and ammonia nitrogen. In wastewater treatment plants, SPC reduces COD, color, and odor while improving dissolved oxygen content. It is also used in soil remediation to oxidize petroleum hydrocarbons and pesticide residues, restoring soil vitality and promoting microbial regeneration.

Medical and Personal Care Applications

• In the medical field, Sodium Percarbonate is used in disinfectant formulations for instruments, surfaces, and wound care products. Its decomposition produces active oxygen, which kills bacteria and viruses without toxic residues. In personal care products such as toothpaste and denture cleaners, SPC acts as a mild whitening and sterilizing agent. It releases oxygen bubbles to clean dental surfaces and remove stains, improving oral hygiene while being gentle to mucous membranes and enamel.

Agriculture and Aquaculture

• Sodium Percarbonate is applied in agriculture as a soil oxygenator, disinfectant, and water treatment additive. It improves soil aeration, suppresses pathogenic fungi, and promotes nutrient absorption in crops. In aquaculture, SPC oxidizes organic matter, increases dissolved oxygen, and controls ammonia levels, thereby maintaining a healthy environment for fish and shrimp. Its non-toxic and non-chlorinated properties make it safe for sustainable agricultural and aquaculture systems.

Chemical and Industrial Uses

• In chemical industries, Sodium Percarbonate acts as an oxidizing agent and raw material for producing other peroxygen compounds. It is used in polymerization reactions, oxidative synthesis, and the manufacturing of bleaching activators such as TAED. Its stability, easy handling, and solid-state form make it a preferred source of hydrogen peroxide in applications requiring controlled oxygen release.

Emerging and Specialized Applications

• Sodium Percarbonate is increasingly used in air purification, electronics cleaning, and emergency oxygen supply systems. It helps remove odor and microbial contamination in HVAC systems, provides eco-friendly cleaning for precision instruments, and functions as an oxygen source in specific industrial processes. With growing demand for sustainable oxidation technologies, SPC is becoming an essential chemical for green industrial operations.
