What is Sodium Acetate?
Sodium Acetate is the sodium salt of acetic acid, available in both anhydrous and trihydrate crystalline forms. It is a white, mildly alkaline solid widely used as a food preservative and flavouring agent, a buffering agent across numerous applications, and as a functional additive in textile processing and construction materials. Its ability to form a stable buffer system with acetic acid makes it particularly valuable in applications requiring precise pH control.
Polychem Industries supplies Sodium Acetate in food grade and industrial grade to food manufacturers, textile dyeing companies, concrete admixture producers, and various industrial chemical formulators across India and internationally. Its versatility as both a food ingredient and an industrial buffering and processing aid makes it one of the most widely used acetate salts in commercial use.
Available Grades
| Grade | Form | Purity | Standard | Applications |
|---|---|---|---|---|
| Food Grade | White crystalline powder/granules | 98%+ (Food / Industrial Grade) | FSSAI / FCC / E262 | Food preservation, flavouring, buffer systems |
| Industrial Grade | White crystalline powder/granules | 98%+ | Industrial | Textile dyeing, concrete admixtures, buffer solutions, heat packs |
Applications & Uses
Food Preservation & Flavouring
Used as a preservative and flavouring agent in various food products, particularly in snack foods and certain processed foods, where it provides a mild vinegar-like flavour note and contributes antimicrobial preservative action.
Buffer Solutions
Widely used in combination with acetic acid to create acetate buffer systems for laboratory, pharmaceutical, and industrial applications requiring stable pH control in the moderately acidic range.
Textile Dyeing & Processing
Used in textile dyeing operations as a buffering agent to control and maintain the pH of dye baths within the optimal range for specific dye classes, helping ensure consistent and predictable dyeing results.
Concrete Admixtures
Used as a set retarder and admixture component in certain concrete and cement formulations, helping control the setting time of concrete in specific construction applications.
Heat Packs & Thermal Applications
The trihydrate form of Sodium Acetate is used in reusable heat packs, taking advantage of its supercooling and crystallisation properties to release stored heat on demand when triggered.
Corrosion Inhibition
Used in certain corrosion inhibitor formulations and de-icing applications, taking advantage of its chemical properties as an alternative to more aggressive de-icing chemicals in specific applications.
