Sodium Hydrosulfite Market Size, Share, Growth, Trends, and Global Industry Analysis: By Process (Zinc Process, Sodium Formate Process, Others), By Formulation (Powder, Liquid), By Application (Textiles, Wood Pulp Bleaching, Mineral Flotations, Food and Beverages, Cosmetics and Personal Care, Others) and Region Forecast 2021-2032

Sodium Hydrosulfite Market size was valued at US$ 1.4 billion in 2025 and is expected to reach US$ 1.7 billion by 2032, growing at a significant CAGR of 2.5% from 2026-2032. Due to surge in demand for sodium hydrosulfite from end user industries such as textiles, paper and pulp, food and beverages, and others across the world. Moreover, technological advancements in the manufacturing of sodium hydrosulfite, wide range of market players providing the raw materials for sodium hydrosulfite manufacturing, and multiple applications with sodium hydrosulfite propel the global market revenue over the forecast years.

However, availability of alternative products and decrease in paper and pulp market are expected to hamper the growth of sodium hydrosulfite revenue in future years.Sodium hydrosulfite, often known as sodium hydroxide, is a colourless or yellow-colored crystal with the formula NaHS. Sodium dithionite is another name for sodium hydrosulfite. It remains stable under normal settings but degrades when exposed to an acidic element/compound or hot water. Different processes, such as the zinc dust process, amalgam procedure, and formate procedure, are used to make sodium hydrosulfite. To make sodium hydrosulfite, you'll need to follow these three steps. Furthermore, in 2014, zinc dust and amalgam processes accounted for around 80% of global manufacturing. In an acidic medium in a warm climate, sodium hydrosulfite has diminishing characteristics.
