Description

Aluminum Chlorohydrate CAS NO 1327-41-9 is a high-purity, polymeric aluminum complex widely recognized as a highly effective primary coagulant and flocculant. Its primary value lies in its superior performance in water purification, offering high charge density and efficiency over a broad pH range compared to traditional aluminum salts. This makes it an essential chemical for industries requiring rigorous water treatment, such as municipal drinking water facilities, industrial wastewater management, and paper manufacturing.

Application

• Municipal and Industrial Water Treatment: As a primary coagulant for removing suspended solids, organic matter, and phosphates from drinking water and process wastewater.
• Paper and Pulp Industry: Used for retention aid, drainage improvement, and as a component in sizing formulations to control water absorption.
• Cosmetics and Personal Care: Serves as the active ingredient in antiperspirants and deodorants due to its efficacy in controlling perspiration.
• Textile Manufacturing: Acts as a mordant in dyeing processes to improve color fastness and as a coagulant in effluent treatment.
• Oil and Gas Industry: Employed in water clarification and as a gel-forming agent in fracturing fluids.
• Pharmaceuticals: Used as an adjuvant in vaccine formulations and in the production of certain antacids.
• Construction Chemicals: Functions as an accelerator in some concrete formulations and in waterproofing agents.

Quality Control

Our Aluminum Chlorohydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and compliance with relevant industry standards, including those for water treatment chemicals (AWWA, NSF) and cosmetic-grade materials. A comprehensive Certificate of Analysis (COA) detailing assay, basicity, impurity levels, and physical specifications is provided with every shipment to guarantee traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep containers tightly sealed when not in use to prevent absorption of atmospheric moisture and CO2, which can affect product performance. Store away from incompatible materials such as strong bases.
