Catalase

Catalase (CAS 9001-05-2), also supplied under trade names such as Equilase and Caperase, is an oxidoreductase enzyme that decomposes hydrogen peroxide into water and oxygen. In industrial settings, it functions as a biological catalyst to eliminate residual peroxide from process streams. This enzyme protects product quality and downstream process integrity by neutralizing oxidative agents. In dairy and food processing, it removes hydrogen peroxide used as a cold sterilant in milk and cheese production, enabling compliant, residue-free output.

Textile and paper manufacturers use it to decompose bleaching peroxide before dyeing or coating steps. This prevents uneven results and chemical interference during the manufacturing process. Pharmaceutical and biotech producers incorporate it into enzymatic reaction systems. It is also used in cell culture media where peroxide accumulation would degrade sensitive biologics or active compounds. Cosmetic and personal care formulators apply it as a stabilizing enzyme to neutralize oxidative byproducts in peroxide-based formulations.

The product is supplied as a liquid concentrate or lyophilized powder, with activity expressed in units per milliliter or per gram. Food-grade material is available to FCC specifications to ensure safety and compliance. Pharmaceutical-grade product is offered to USP or BP standards for high-purity applications. Grades sourced from Aspergillus niger or bovine liver are common, with activity levels varying by specific application requirements.
