AqFresh™ technology eliminates a broader range of household smells – free odour test report

AqFresh™ technology eliminates a broader range

AqFresh™ technology eliminates a broader range of household smells, including 10 common complex malodours.

– free sensory odour test report of YOUR formula.*

Instantly effective in solid or liquid formats, it keeps working when both wet and dry. Formulation flexible, it works in aerosol, aqueous or alcohol-based solutions, and is compatible with common cleaning product ingredients.

Our unique patented odour capture technology consists of cucurbiturils – barrel-shaped molecules with a hydrophobic cavity and polar portals that powerfully attract and capture VOCs. They act rapidly and keep on working for lasting freshness. AqFresh™ contains a mixture of cucurbit[n]urils (n =6, 7, 8) and each homologue has affinity for a variety of molecules. Thus, AqFresh™ has exceptional capability to bind a wide spectrum of molecules with different sizes and functional groups.

Range of household malodours

Common Household Malodours

Bad household smells trigger negative emotions, such as irritation, stress & anxiety, or a bad mood, according to the Aqdot 2021 survey of over 500 consumers in North America, Europe and Asia. Rotting food smells (fish, rotten egg, milk, cheese, cooking fat) for example, are particularly associated with triggering feelings of being distracted or nauseous.

Many household cleaning products use strong chemicals with even stronger smells. Fragrance is often added to mask the product smell and to give a signal of ‘freshness’ post-cleaning. However, as fragrances are highly volatile, they quickly dissipate, so the malodour can remain distinctly noticeable.

The fact that bad smells are annoying creates a negative emotional experience which becomes associated with using that household cleaning product. However, consumers don’t think that using a strong fragrance to mask the product is a good solution either. For example, 51% prefer an air freshener spray that is fragrance-free or only lightly fragranced and just 14% prefer a strongly fragranced one.


AqFresh™ outperforms benchmarks for a broader range of malodours

We have selected some of the most common household smells, and of these we outperform two leading competitor technologies substantially.  In each case the performance is benchmarked against the next best product – which varies between them depending on the odour, highlighting that competing technologies struggle at removing this breadth of odours, as well as some specific ones. In conclusion, AqFresh™ technology eliminates a broader range of household smells.

Sensory Odour Test

Aqdot has its own externally-validated trained expert panel of assessors who follow a standard sensory odour test protocol to evaluate the intensity of residual malodour after treatment with the test formulation vs a control. The panel uses trained assessors selected according to ISO 8586 for their ability to discriminate and describe malodour. Aqdot train & assess them quarterly using validated polymeric standards provided by a well-known multi-national olfactory company.

Analytical GC-HS Test

The analytical testing is run by Aqdot using gas chromatography to analyse the amount of residual malodour molecules present in the headspace after treatment with the test formulation vs a control. Gas chromatography (GC) is an analytical technique that helps to separate and analyse a mixture of compounds that can be vaporized without their decomposition. Headspace (HS) analysis is a technique for analysing volatile organic compounds (VOCs) by collecting the gaseous headspace for introduction into the GC.


Improving indoor air quality

AqFresh™ is a revolutionary new 5-in-1 molecular capture and release technology that removes odours, pollutants, allergens & viruses whilst delivering prolonged fragrance release, to improve indoor air quality.

AqFresh™ is non-toxic, works in more formulations and environmental conditions, faster, for longer. It has been proven in sensory, gas chromatography, consumer & clinical testing to remove a broader range of pollutants, viruses, odours & allergens and give longer-lasting fragrance release.

AqFresh™ technology eliminates a broader range of household smells.
