Description

Calcium Peroxide is an inorganic peroxide compound valued for its controlled release of oxygen and its role as a versatile oxidizing agent. This makes it a critical functional ingredient across numerous industrial and environmental processes where oxidation, bleaching, or oxygen generation is required. Key industries that rely on this material include food production, wastewater treatment, agriculture, and polymer manufacturing.

Application

• Food Industry: Used as a dough conditioner and bleaching agent in flour and bakery products to improve texture and whiteness (subject to local food additive regulations).
• Environmental Remediation: Applied in-situ for groundwater and soil remediation to degrade organic contaminants through chemical oxidation.
• Agriculture & Horticulture: Functions as a seed disinfectant and as a source of oxygen in soil conditioners to improve root growth in compacted or waterlogged soils.
• Wastewater Treatment: Employed as an oxidizing agent to reduce odors, break down organic pollutants, and assist in sludge treatment.
• Polymer Industry: Acts as a curing agent and initiator in the production of specific polymers and composites.
• Dental & Oral Care: A component in certain tooth-whitening and oral hygiene products for its mild bleaching action.
• Aquaculture: Used to increase dissolved oxygen levels in ponds and improve water quality for aquatic life.

Quality Control

Our Calcium Peroxide is manufactured under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for purity, active oxygen content, and particle size distribution. Certificates of Analysis (COA) are provided with every shipment, and we can support compliance with relevant standards such as FCC for food-grade applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as acids, organic substances, and reducing agents. Due to its oxidizing nature, keep away from heat, sparks, and open flames. Store under conditions recommended on the Safety Data Sheet (SDS).
