Aqueous Glutaraldehyde 50 Biocide

Categories: ,


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

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

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 former’s carbonyl group and the latter’s amino group. Among the known aldehydes, glutaraldehyde products are one of the best protein cross-linking agents.

Aqueous glutaraldehydes 50% have a minor 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 particular concern from people and has been put to general use.

The glutaraldehyde 50 should be stored in room shady and dry place.

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.
