Description

Aluminum Acetate CAS NO 139-12-8 is an inorganic salt formed from aluminum and acetic acid, commonly available in its basic form. This compound is valued for its astringent, antiseptic, and buffering properties, making it a versatile intermediate and functional ingredient. It is primarily sought after by manufacturers in the pharmaceutical, personal care, and industrial chemical sectors for formulating topical solutions, antiperspirants, and mordants.

Application

• Pharmaceutical Manufacturing: Used as an active ingredient and buffering agent in topical astringent solutions, antiseptic lotions, and medicated powders for skin conditions.
• Personal Care & Cosmetics: Serves as a key component in antiperspirant and deodorant formulations due to its pore-constricting and sweat-reducing effects.
• Textile Industry: Acts as a mordant in dyeing processes to improve the colorfastness of fabrics when using certain dyes.
• Water Treatment: Employed in some industrial water purification systems as a coagulant aid and for phosphate removal.
• Industrial Chemical Synthesis: Functions as a catalyst or precursor in various organic synthesis and polymerization reactions.
• Laboratory & Research: Utilized in analytical chemistry and as a reagent for preparing other aluminum compounds.
