Calcium acetate

Calcium acetate (CAS 62-54-4), also known by the E-number E263, is an inorganic calcium salt used across food, pharmaceutical, and cosmetic manufacturing. It functions primarily as a preservative, pH buffer, and sequestrant in formulated products. In food production, E263 controls acidity and extends shelf life in baked goods, confectionery, and processed foods where microbial stability is a formulation priority. This additive is essential for maintaining product integrity over time.

Pharmaceutical manufacturers use it as an active excipient in phosphate-binding preparations, including branded products such as Phoslyra and PhosLo, targeting renal patient formulations. It is a critical component in specialized medical treatments. In personal care, it acts as a buffering agent and firming component in creams, gels, and topical formulations requiring controlled pH. These properties ensure the stability and efficacy of various cosmetic and dermatological products.

Industrial applications include its use as a catalyst precursor in acetone production and as a setting agent in textile and paper processing. Its versatility makes it a valuable chemical across multiple manufacturing sectors. Calcium acetate is supplied as a white crystalline powder or granules, with monohydrate being the most commercially prevalent form. Standard grades include food-grade (FCC), USP, and BP specifications for global supply chains.

Bulk quantities are available for industrial use, with pharmaceutical-grade material subject to stricter purity and documentation requirements. This ensures that all regulatory standards are met for sensitive applications in healthcare.
