The technology behind ONA was initiated over 25 years ago. The scientist (who was eventually credited with the invention of ONA) became fascinated when he observed that when terepenes were diffused into the environment, emission’s and odours were reduced.
Inspired by this finding, further evidence showed that the odours were not just masked but permanently removed. The result was a set of specialized formulations that neutralise a wide spectrum of organic and inorganic odour problems – effectively, efficiently and permanently.
ONA odour neutralisation formulations have been scientifically engineered to be environmentally safe. Manufactured under strict quality controls, the components of ONA are generally recognised as common in the food industry and have a long history of safety.
Terpenes are widespread in nature, mainly in plants as constituents of essential oils. Many terpenes are hydropocarbons, but oxygen-containing compounds such as alcohols, aldehydes or ketones (terpenoids) are also found. Their building block is the hydrocarbon isoprene, CH2=C(CH3)-CH=CH2*
*Isoprene Rule, Wallach 1887
- Terpenes have anti-bacterial, antifungal and anti-septic properties.
- Terpenes have oxygenating properties (increases oxygen level).
- When diffused into the environment, terpenes have been found to reduce airborne chemicals and bacteria.
- Terpene characteristics appear to either destroy the odour molecule or convert it to a more acceptable level.
ONA the Mechanisms of Action
There are three mechanisms of action that can occur, based on the chemical and physical natures of each terpene and active ingredient versus the organic and inorganic volatile compounds (odours).
Absorption – the attraction of the different reactive sites on the ONA odour neutralising agents active ingredient molecules will attract and non-permanently bind with the low molecular, high weight compound (VOC) aka odours.
Absorb: To retain wholly, without reflection or transmission, what is taken in.
Adsorption – All VOC’s and odourous compounds have a solubility factory in ONA odour neutraliser active ingredients. This solubility will allow the VOC compound to solubilise itself in the presence of ONA, relative to the chemistry of the emission, temperature, pH and pressure of the environment .
Adsorb: To collect and hold (gas or vapour) in the surface of the solid.
Chemical Reaction (The Pairs Theory*) – This involves the permanent bonding of the odourous molecule (VOC) and the ONA active ingredients reactive sites. The mechanism transforms the pollutant in its basic properties. As a result, odour disappears.
* The Pairs Theory is based on the work of Zwaardermaker, an early 20th century Dutch scientist. The Zwaardermaker Pairs Theory concludes that two or more odours can cancel each other out when they combine in natural bond like attraction.
The affinity of the different odourous compounds (VOC’s) with ONA is directly relative to their chemical composition and physical state. For example, a hydrogen sulphite can have a great affinity for certain sites of the ONA active ingredient. It can bond either electrostatically, or react in comparison to its relative solubility. This means different components will be neutralised by one mechanism compared to the other two, or a blend of each of the three.
The bottom line is ONA is not a masking agent but offers a safe effective way to permanently eliminate odours and emissions.
