Sodium acetate anhydrous is widely used in the food industry as a preservative and flavoring agent, enhancing the taste of various snacks and seasonings. In the textile industry, it serves as a photoresist in dyeing processes, helping to stabilize colors and improve fabric quality. It is also employed in the production of heating pads and hand warmers, where it acts as a key component in phase-change materials due to its ability to release heat upon crystallization. Additionally, it is utilized in biochemistry laboratories as a buffer to maintain stable pH levels during experiments. In wastewater treatment, it is added to support microbial activity and improve the efficiency of biological processes.
