Description
Sodium ascorbate (CAS 134-03-2) is the sodium salt form of vitamin C, registered under EC 205-126-1 with the molecular formula C6H8O6.Na. It is commercially known under names including Е301, Natri-C, Ascorbin, Ascorbicin, and Natrascorb, and is recognized internationally as a food additive without a designated E-number in EU food law.
In food and nutrition manufacturing, sodium ascorbate functions as an antioxidant by donating electrons to free radicals, preventing oxidative degradation in meat curing, beverages, and packaged goods. In personal care formulations, it acts as a skin conditioner and stabilizer, protecting active ingredients from oxidation and supporting product shelf stability.
Sodium ascorbate is available in pharmaceutical-grade (Ph.Eur., USP/FCC) and food-grade specifications as a white to off-white powder. It falls under HS code 29322000 and is subject to REACH registration requirements for EU trade. Standard packaging includes 25 kg bags and fiber drums.
