Borax Pentahydrate (Disodium Tetraborate Pentahydrate)

Borax Pentahydrate, chemically known as Disodium Tetraborate Pentahydrate, is an inorganic compound commonly encountered as a white crystalline powder. It is supplied as a pentahydrate form (Na2B4O7·5H2O), containing approximately 45% boron oxide equivalent by weight, and is readily soluble in water with a slightly alkaline aqueous solution, typically exhibiting a pH range of 9–10. This composition ensures compatibility with formulations requiring buffering and emulsification. Industrial buyers should consider its chemical compatibility, avoiding mixing with strong acids to prevent decomposition and release of boric acid, which can affect product performance. Handling temperatures usually range ambient to 50°C to maintain powder stability and prevent caking during storage and processing. The chemical's reliable crystallinity and solubility profile make it suited for use in sectors requiring precise ingredient functionality. Typically supplied in bulk powder form with particle size distribution optimized for dissolution rates, Borax Pentahydrate is compatible with standard industrial packaging such as 25 kg moisture-resistant bags, facilitating ease of transport and storage. It is imperative that buyers verify the batch-specific Certificate of Analysis to confirm critical parameters such as moisture content and purity, ensuring process consistency.

In detergent and cleaning product manufacturing, Borax Pentahydrate improves water softening capacity and stabilizes active ingredients, which enhances cleaning efficiency and reduces residue formation. Its alkaline buffering capability helps maintain formulation pH, essential for optimal surfactant performance and long shelf life. Without effective water softening agents like borax, detergent formulations would require higher surfactant loads or additional chemicals, increasing costs and environmental impact. In glass and ceramics production, the compound acts as a flux, lowering melting temperatures and reducing energy consumption during firing and melting processes. This leads to improved product quality with enhanced strength and finish, contributing to operational cost savings and consistent batch quality. Additionally, its role in agriculture as a controlled boron source is crucial since boron deficiency adversely affects plant growth, impacting crop yields and fertilizer product efficacy.
