Among the most widely commercially used aldehydes, glutaraldehyde – the 5 carbon dialdehyde – was first described in the chemical literature by Harries and Tank in 1908, and first introduced commercially in 1951. It is generally available from chemical suppliers as acidic aqueous solutions (pH 3.0–4.0), ranging in concentration from less than 2% to 70% (w/v). Glutaraldehyde reacts rapidly with amine groups at around neutral pH. It has been widely studied and reviewed by government authorities for its safety and efficacy.

Properties of Glutaraldehyde

Today glutaraldehyde is found as the active ingredient in many products used for water treatment, hospital disinfection, in microscopy laboratories as a crosslinking agent, in oil and gas manufacture, tanning and leather goods production, metal working and heat transfer fluids, agricultural paints and adhesives, and surface cleaning uses to name but a few.

Because the safety and efficacy profile is so well known, Microbide uses a complexed glutaraldehyde as a benchmark for the performance attributes of the series of complexed aldehydes which we have in development. As a complexed aldehyde it is a powerhouse of biocidal capability with greatly reduced fumes.
