About Sodium Hydrosulfite 88% Industrial Grade

Sodium Hydrosulfite 88% Industrial Grade is widely used as a reducing agent and bleaching agent mainly in the textile industry for removing excess dye and improving fabric brightness. It also finds application in water treatment for removing residual chlorine and controlling oxygen levels in boiler feed water. This chemical requires careful handling and storage in cool, dry, and ventilated areas as it is sensitive to moisture and heat which can cause decomposition. Finstar Chemicals supplies Sodium Hydrosulfite in 50 kg drums to industrial customers, ensuring reliable procurement with batch traceability documentation. Its stability under recommended storage conditions allows sustained efficacy during transportation and storage in local environments. The chemical facilitates efficient dye reduction and dechlorination processes, enhancing endpoint chemical quality and reducing impurities. Procurement teams will benefit from Finstar’s regionally optimized logistics for Kenya, ensuring timely deliveries and consultation for quantity optimization based on the intended industrial application. Proper use of Sodium Hydrosulfite avoids fabric damage caused by over-bleaching and reduces downtime caused by chlorine-contaminated water in boiler systems. Industries using Sodium Hydrosulfite must enforce strict safety protocols due to its reactive nature and potential to release sulfur dioxide gas when exposed to acids or moisture. Finstar Chemicals is able to provide Certificates of Analysis and recommendation for safe handling practices to support compliance and operational safety requirements. Overall, reliable and consistent supply of Sodium Hydrosulfite 88% Industrial Grade along with expert technical advisory creates tangible efficiency improvements for textile manufacturers and water treatment operators in the region.
