About this product

Sodium Metabisulfite is a versatile inorganic chemical compound presented as a white or light-yellow crystalline powder, primarily functioning as a potent reducing agent and preservative. Its key characteristic is its distinctive sulfur dioxide (SO2) smell, and it exhibits slight solubility in alcohol while being susceptible to decomposition by moisture, readily oxidizing to sodium sulfate upon exposure to air. While specific technical specifications and performance metrics are not detailed, its chemical properties indicate efficacy in various industrial processes. The product is typically supplied in a crystalline powder form, with construction quality and finish options not explicitly stated in the provided information. Size ranges, variants, or customisation options are also not mentioned. Typical applications for Sodium Metabisulfite include its use as a food preservative (E223), an antioxidant, a bleaching agent in textiles and paper manufacturing, and in water treatment as a dechlorinating agent. It is also employed in the photographic industry and as a laboratory reagent. Target buyers for this chemical product encompass importers, wholesalers, and end-use industries such as food and beverage processing, textile manufacturing, paper production, and water treatment facilities.
