Femcare & Babycare Nonwovens with AqFresh™ have up to 95% less urine & sweat malodour in sensory testing – free odour test


New AqFresh™ technology has been proven to capture urine and sweat malodours when dry impregnated into femcare and babycare nonwovens.

AqFresh™ consists of Cucurbiturils – barrel-shaped molecules with a hollow hydrophobic cavity and polar portals enabling it to capture & hold the malodours with extremely tight binding so they are virtually undetectable to the typical consumer. Unlike existing anti-odour solutions, AqFresh™ works in wet environments where femcare & babycare nonwovens are typically used, and does not rely on sensitising or allergenic fragrances or on antibacterials 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. Triethylamine or Isovaleric Acid were added to the nonwoven. The headspace was evaluated and compared to control (100% malodour before adding to the AqFresh™-impregnated nonwoven). The results showed that the level of malodour was reduced by up to 95% in the nonwoven with AqFresh™.

Aqdot at Tech Textil Frankfurt

Come and meet the Aqdot team at our stand #B80, hall 11 at Tech Textil Frankfurt, 21-24 June 2022. Learn more about our revolutionary patented technology and touch & smell a range of non-woven, textile and coated textile materials impregnated with AqFresh™ odour capture technology.


Malodours from Femcare & Babycare Nonwovens

Capturing external odours & pollutants is a key priority for manufacturers of feminine/adult care, baby care, and air-filter products. Current odour counteracting technologies are relatively ineffective and rely on fragrances to mask the odour. Nonwovens are widely used in this industry for panty liners, pads, diapers, nappies, intimate wipes and air-filters.

AqFresh™ is a versatile odour & pollutant capture technology with the potential to be incorporated into nonwovens produced using a variety of methods whether needlepunched, spunbonded, airlaid or meltblown. Manufacturers can reduce malodours by using AqFresh in polypropylene (PP), polyester (PE) and many more types of nonwovens, to provide the desired perception of freshness for these consumer products.

Malodour and pollutant reduction through nonwovens is of importance to a huge range of nonwoven applications including femtech, babytech, filters (HEPA), clothtech, hometech, indutech, medtech, mobiltech, protech, packtech, and sportech.


Odour Test

The odour test is run by Aqdot using trained assessors selected according to ISO 8586 for their ability to discriminate and describe malodour. They are trained & assessed quarterly 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 nonwoven materials, in order to capture malodours.

This patented technology consists of cucurbiturils: barrel-shaped molecules with a hydrophobic cavity and polar portal. Their unique structure enables exceptionally tight capture & binding of unwanted molecules.

AqFresh™ has been successfully impregnated into nonwovens, textiles and textile coatings to remove VOCs, odours & pollutants released by these materials themselves as well as capturing external environmental odours.

AqFresh™ has been proven to capture a wide range of malodours relevant to broader nonwoven applications including: putrescene & cadaverine (wounds), isovaleric acid (sweat), trimethylamine (urine) and skatole (faeces). It has also been shown to reduce VOCs enabling nonwovens, for example as used in car headliners, to meet the VDA-270 standard for automotive interiors.

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




Job Vacancy: R&D internship (10-13 weeks)

Explore the science and develop applications of novel supramolecular chemistry.

Aqdot is a small, rapidly developing company with a positive, diverse (age, gender, nationality) team.
We are making and applying a safe, novel, multifunctional, supramolecular chemistry that removes bad smells and pollutants, cleverly releases fragrances, stabilises enzymes, provides unique properties to hydrogels and even inactivates allergens and viruses. We develop applications for this chemistry in our well-equipped laboratories.
We are seeking interested and able physical scientists to work in our R&D team to develop and test new product concepts. The main activities will be developing formulations and making physico-chemical measurements.
The internships are ideal for curious, rigorous and enthusiastic young scientists-who are about to start or have just completed their final undergraduate year.
