Aqueous Glutaraldehyde 50 Biocide

Categories: ,


Aqueous glutaraldehyde 50 is a colorless or yellowish clear and bright liquid with a slight irritating smell. 50% glutaraldehyde aqueous can be dissolved in organic dissolvents. Such as water, ether, and ethanol.

In water solution, glutaraldehydes don’t exist much in a free state. Instead, glutaraldehydes make an appearance as hydrates with different forms and most of the glutaraldehydes are hydrates with annular structure.

Melting Point-5.8 deg c.
Boiling Point101 deg c.
Refractive Index1.373
Water Solubilitymiscible

Glutaraldehyde aqueous 50 biocide is reactive in property, and liable to polymerize and oxidize, which will react with compounds containing active oxygen and nitrogen. The reaction of the glutaraldehydes with protein is mainly carried out between the carbonyl group of the former and the amino group of the latter. Among the known aldehydes, glutaraldehyde products are one of the best cross-linking agents for proteins.

Aqueous glutaraldehydes 50% has a small influence on the activity of the enzyme, and most of the enzymes can be fixed under controlled conditions, to cross-link without losing their activity. Contributing to its outstanding characteristics, glutaraldehyde biocide has drawn special concern from people and been put at broad uses.

Safe Protection:

Glutaraldehyde has toxicity. It is harmful to the human respiratory tract like formaldehyde. Glutaraldehyde can cause bronchitis and pulmonary edema problems if people have Long-term exposure. At the same time, glutaraldehyde has a physical hazard. It is irritating to the skin and mucous membranes. People should avoid direct contact with glutaraldehyde disposal in the air.
