Aldehydes and their biocidal capabilities
Aldehydes are organic compounds containing a carbonyl group, ( -CHO) a carbon double bonded to oxygen bonded to hydrogen and another group. By definition, the aldehyde carbonyl group must always lie at the end of a carbon chain in order to provide both the –OH and –H components of the carbonyl. The C=O bond (double bond) is highly polar.
Aldehydes are widespread in nature, and are derived from both plants and animals. The aldehydes are very reactive.
Aldehydes exist as mono- and di- aldehydes, having one or two reactive moieties respectively. Many of the di-aldehydes are derived from petrochemicals.
Biocidal capacity of aldehydes
The biocidal capacity of aldehydes depends on the environment in which it is used, particularly: the target organism or microbial ecosystem, the concentration, contact time, pH and temperature.
In order to harness the biocidal capacity of various aldehydes, Microbide uses a patented process to 'complex' the active aldehyde ingredient with a number of inactive ingredients to hold the aldehyde in solution and reduce its volatility. By associating various aldehydes with surfactants and other biodegradable ingredients, the aldehyde is protected by its association in micellular structures. The micelles directionally point the active carbonyl group of the aldehyde toward the surface of the solution; thereby making the aldehyde biocide far more effective at killing germs.
Microbide Micellised Products
Microbide’s solutions are developed at neutral pH for each active aldehyde ingredient. There is no requirement for activation prior to use.
Head-to-head comparative studies of Microbide’s complexed aldehydes versus their non-complexed market leading counterparts demonstrate significant improvement in efficacy, together with a reduced volatility profile and improved safety.
Microbide are developing a series of both complexed mon- and complexed di- aldehydes and combination products to address specific microbial control issues.
The majority of our product range is biodegradable with the exception of Microbide-O: a HLD is our only non-biodegradable product. In general most aldehydes with ring structures (for example ortho-phthalaldehyde) are not readily biodegradable.
