Reduce malodours from chronic wounds by 78%

using non-woven dressings with new AqFresh™ technology

– free odour test report


New AqFresh™ odour elimination technology has been proven to reduce malodours from chronic wounds (eg. putrescene and cadaverine) when dry impregnated into non-wovens.

AqFresh™ consists of Cucurbiturils – barrel-shaped molecules with a hollow hydrophobic cavity and polar portals. This unique structure enables it to capture & hold the malodours with extremely tight binding. Therefore they are virtually undetectable to the typical patient. Unlike existing anti-odour solutions, AqFresh™ works in wet environments like chronic wound dressings and does not rely on to which bacteria are becoming increasingly resistant.

In these studies, a section of the AqFresh™-treated nonwoven was placed in a Gas Chromatography headspace (HS-GC) vial. Putrescene was added to the nonwoven. The headspace was evaluated and compared to control and untreated nonwoven. The results showed that the level of malodour was reduced by 78% in the non-woven with AqFresh™ compared to the non-woven without AqFresh™.

Reduce malodours from Chronic Wounds

Tackling malodours from chronic wounds is a key priority for healthcare workers, carers and patients in the medical sector of the non-wovens industry. A key objective is to help patients overcome social embarrassment & isolation due to the smell.

Current odour technologies such as charcoal only work when dry whilst silver is relatively ineffective and relies on antimicrobial action to which bacterial resistance is increasing.

As well as for advanced wound care, non-wovens are widely used in the medical & healthcare sector. For example, hospitals use them for surgical gowns & face masks, bed linen, underpads, ostomy bag liners, PICO dressings and sterilisation wraps. In wound care, non-woven bandages are used to provide a moist wound healing environment, with controlled vapour transmission, absorbency and low skin adhesion. Hydrocolloid dressings are often used provide a moist and insulating healing environment with gel-forming agents, a waterproof backing and gauze.


Odour Test

The odour test is run by Aqdot using trained assessors selected according to ISO 8586 for their ability to discriminate and describe malodours. They undergo training and a quarterly assessment using validated polymeric standards provided by a qualified supplier.

The panel carry out the odour tests to evaluate the impact of our counteractant. The panellists evaluate the odour intensity based on the scale from 0 to 6 (not detectable to extremely strong odour) and the hedonic tone from -4 extremely unpleasant to +4 extremely pleasant.


AqFresh™ odour capture technology

AqFresh™ odour capture technology can be dry impregnated into non-woven materials. As a result, it can capture malodours, such as those arising from chronic wound dressings.

This patented technology consists of cucurbiturils, which are barrel-shaped molecules with a hydrophobic cavity and polar portal. Most importantly, their unique structure enables exceptionally tight capture & binding of unwanted molecules.

We have proven that AqFresh™ can capture a wide range of malodours relevant to broader non-woven applications. Some examples include: putrescene & cadaverine (wounds), isovaleric acid (sweat), trimethylamine (urine) and skatole (faeces).

In conclusion, AqFresh™ is available as powder which has been successfully demonstrated to reduce malodours when dry impregnated into non-woven materials.


A nice alternative for AqFreshTM powder impregnation: Fibroline technology

Fibroline is an engineering company which developed and patented innovative dry impregnation technologies. Those cleantechs enable to impregnate powder form materials into porous structures thanks to high intensity alternating electric fields.
