Product Description

Product Description

Sodium Ascorbate 

    Sodium Ascorbate is the sodium salt of ascorbic acid (vitamin C), appearing as a white to slightly yellow crystalline powder that is odorless and stable in air but gradually darkens upon exposure to light . It is produced by neutralizing ascorbic acid with a sodium base such as sodium bicarbonate or sodium carbonate, resulting in a compound with the molecular formula C₆H₇NaO₆ and a molecular weight of 198.11 g/mol . Unlike ascorbic acid, sodium ascorbate offers neutral pH, enhanced stability, and reduced acidity, making it suitable for individuals with sensitive stomachs and for formulations requiring a non-acidic vitamin C source . It is classified as a food additive with the International Numbering System designation INS No. 301 and is Generally Recognized as Safe (GRAS) by regulatory agencies including the FDA and EFSA .

Application

Food and Beverage Industry

Pharmaceutical and Nutraceutical Applications

    Sodium ascorbate serves as a multifunctional food additive (E301) where it acts primarily as an antioxidant and preservative to extend shelf life by preventing oxidative rancidity and discoloration in processed foods . It is commonly added to meat products, fruit juices, canned fruits, beer, and carbonated beverages to maintain freshness and color stability . As a nutritional fortifier, it provides a stable source of vitamin C in breakfast cereals, dairy products, and functional beverages without contributing to acidity . In processed meats, it functions as a color retention agent and synergist with other antioxidants to preserve product quality .

    In pharmaceutical formulations, sodium ascorbate is employed as an active ingredient in vitamin C supplements and as an antioxidant stabilizer in injectable solutions and oral dosage forms . Its neutral pH makes it preferable for formulations where acidity could cause irritation or incompatibility with other ingredients . It is widely used in multivitamin preparations, effervescent tablets, and powdered drink mixes as a bioavailable source of vitamin C that supports immune function and overall health . In parenteral nutrition, it helps maintain the stability of other vitamins and nutrients .

Cosmetics and Personal Care Products

Research and Laboratory Applications

    In the cosmetics industry, sodium ascorbate is valued for its antioxidant, skin-brightening, and anti-aging properties . It is incorporated into serums, creams, lotions, and masks to protect skin from environmental oxidative stress, reduce the appearance of fine lines, and promote a more even skin tone . Its gentle, non-irritating nature makes it suitable for sensitive skin formulations where ascorbic acid might cause stinging or redness . It also contributes to collagen synthesis, supporting skin elasticity and firmness .

    In biochemical and cell culture research, sodium ascorbate serves as a reducing agent and antioxidant in various assays studying oxidative stress, cellular functions, and neuroprotection . It is used as a stabilizer in molecular biology protocols and as a supplement in cell culture media to maintain reducing conditions . Research applications include studies on cancer cell proliferation, where high doses have demonstrated selective cytotoxicity, and investigations into neuroprotective effects against oxidative damage .
