Sodium acetate trihydrate

Sodium acetate trihydrate (CAS 6131-90-4), also known as hot ice, is the crystalline hydrated form of sodium acetate used across food, pharmaceutical, and industrial processing. It functions primarily as a pH buffer, preservative, and chemical intermediate.

This versatile compound offers controlled acidity management in aqueous systems. In food production, it regulates acidity in snack seasonings, sauces, and cured meats while extending shelf life as a preservative.

Pharmaceutical manufacturers use it as a buffering agent in intravenous solutions, dialysis fluids, and topical formulations. Precise pH control is critical to product stability in these sensitive medical applications.

Water treatment operations apply it as a carbon source to support biological denitrification in municipal and industrial effluent systems. This process is essential for maintaining environmental safety standards.

Personal care formulators incorporate it into shampoos, skin creams, and toners to stabilize pH across a broad range of finished product types. It ensures the consistency and safety of various cosmetic goods.

Sodium acetate trihydrate is supplied as white crystalline granules or powder. Standard commercial grades include food-grade (FCC), USP, BP, and Ph. Eur. specifications for regulated applications.

These certifications support use across food, pharmaceutical, and cosmetic supply chains. Technical grade is also available for industrial and water treatment use where pharmaceutical documentation is not required.
