Odour and smells

An odor, odour or fragrance is caused by one or more volatilized chemical or organic compounds, generally at a very low concentration, that humans or other animals perceive by the sense of smell. Odors are also commonly called scents, which can refer to both pleasant and unpleasant odors. The terms fragrance and aroma are used primarily by the food and cosmetic industry to describe a pleasant odor, and are sometimes used to refer to perfumes. In contrast, malodor, stench, reek, and stink are used specifically to describe unpleasant odor. The term smell (in its noun form) is used for both pleasant and unpleasant odors.

Volatile organic Compounds

The majority of odours consist of Volatile Organic Compounds. ‘’volatile’’ means that these elements evaporate and can easily get into the air at room temperature. That’s why the ‘’smell’’ hangs around in the air until it evaporates.

Smells in the Indoor Environment

The human sense of smell is a primary factor in the sensation of comfort. Olfaction as a sensory system brings awareness of the presence of airborne compounds. Perception of odor and of irritation is unique to each person, and varies because of physical conditions or memory of past exposures to similar compounds. A person's specific threshold before an odor becomes a nuisance depends also on the frequency, concentration, and duration of an odor.

Volatile organic compounds (VOCs) may have higher concentrations in confined indoor environments due to restricted infiltration of fresh air, as compared to the outdoor environment; leading to greater potential for toxic health exposures from a variety of chemical compounds.

Health effects of odor are traced to the sensation of an odor or the odorant itself. Health effects and symptoms vary, including eye, nose, or throat irritation, cough, chest tightness, drowsiness, and mood change; all of which decrease as an odor ceases. Odors may also trigger illnesses such as asthma, depression, stress induced illness, or hypersensitivity. Ability to perform tasks may decrease, and other social/behavioral changes may occur.

The Problem: Unpleasant Indoor Odours

For People managing businesses, property and people, maintenance professionals, odours may be an occupational hazard often generated by the business activities themselves. Of course you want to improve the working environment of your employees, maintain a perfect image to keep your buildings from becoming obsolete. After all, It is your brand, reputation and very image of these institutions.

The most traditional way of combatting indoor odours was deodorisers, which of course don’t tackle the root of the problem but mask it. This is comparative to Louise the 14th generously applying perfume to avoid taking a bath. Apart from being a temporary fix, deodorisers are also temporary. Air extraction systems on the other hand are usually oversized, too costly, energy intensive and likely to enlarge the ecological footprint.

This obviously covers Food preparation areas, factories, smoking rooms, diaper changing facilities, Restrooms, Dustbins, Schools, Public transportation facilities, alleyways, hospitals, sports centres, restaurants, canteens, locker rooms, exhibition centres, concert halls etc.

The Solution:

Odor absorbing technologies eliminates these volatile compounds, but goes one step further by incorporating technology that actually absorbs existing odors in the room. These coatings lock the odors onto the surface, yet the actual walls remain odor free. Odour absorbing technology particles are added into solid materials to eliminate unwanted odours by technologically and physically absorbing odor-source molecules, and its incorporation into polymer structures resulting in entrapping and rendering odours that may have been generated from polymer oxidation, migration of external contaminants, or dissolution of additives.

Causes of unpleasant odours

♦ Machinery

♦ Chemicals

♦ Urine

♦ Faeces

♦ Diapers

♦ Food residue

♦ Tobacco smoke

♦ Mould & mildew

♦ Sewer backups

♦ Animals
