Vitamin C Potassium Ascorbate (CAS 15421-15-5) is the potassium salt of L-ascorbic acid, a white crystalline powder or granule that delivers vitamin C activity in a neutralised, low-acidity form for food, pharmaceutical, nutraceutical and agricultural applications. It delivers vitamin C activity in a neutralised, low-acidity form, functioning as an antioxidant and preservative across food, pharmaceutical, nutraceutical, and agricultural applications.
Unlike ascorbic acid, it is suited to pH-sensitive formulations where free acidity is undesirable. Listed under food additive designation E303, it is available in Food Grade and Pharma Grade (USP, Ph. Eur.) forms. Solubility in water is high, supporting use in aqueous and effervescent systems.
Vitamin C Potassium Ascorbate ships from SoleChem stock in Food Grade and Pharma Grade forms. Standard supply is in 25 kg bags or fibre drums, with small-lot quantities available in 1–5 kg units.
SoleChem delivers this vitamin C salt to food and nutrition, nutraceutical and pharmaceutical customers, and holds ISO 9001:2015 and ISO 22000:2018 certification for the food and nutraceutical products it supplies. A certificate of analysis (COA) and safety data sheet (SDS) accompany every delivery, and deliveries reach more than 40 countries. Request a bulk quote for the grade and pack size you need.
