Description

Aluminum acetate (CAS 139-12-8 ), also known as aluminium triacetate, is an aluminum salt of acetic acid used across industrial and pharmaceutical applications. It functions primarily as a coagulant, flocculant, and pH buffer, enabling precise process control in aqueous systems. In textile and leather processing, it acts as a mordant and fixing agent. This chemical improves dye uptake and color fastness on natural fibers and hides. Water treatment operations use it to destabilize suspended particles and colloidal matter for clarification. It facilitates sedimentation in both municipal and industrial effluent streams. In paper manufacturing, it supports fiber bonding and sizing processes, contributing to surface strength. Pharmaceutical and topical formulation manufacturers use it as an astringent active in dermatological preparations. Its coagulating action on proteins supports wound care products. Aluminum acetate is supplied as a white to off-white powder or as an aqueous solution. Technical grade is standard for industrial uses including water treatment and textile processing. Pharmaceutical-grade material meeting USP or BP specifications is available for healthcare and topical formulation applications to ensure high purity standards.
