Aluminum Sulfate Anhydrous is an aluminum salt with immune adjuvant activity. This agent adsorbs and precipitates protein antigens in solution; the resulting precipitate improves vaccine immunogenicity by facilitating the slow release of antigen from the vaccine depot formed at the site of inoculation.
Aluminum Sulfate is a commonly used industrial chemical. The compound of aluminum, sulfur and oxygen is often a dry crystal, powdery substance that becomes slimy when wet and is non-combustible. The solution, Al2(SO4)3, is also known as “Alum” and has been in use since ancient Egyptian times when it helped the dyeing process. Today, aluminum sulphate is still used to help print on paper as well as several other industrial purposes, including household products and wastewater treatment.
